    It is one thing to master a cocktail recipe—that impeccable Negroni ratio, the exact length of time to stir a Martini, the just-right orange liqueur and cognac to make a killer Sidecar. It is quite another thing to make that cocktail with style. And style is not spilling a half-ounce of vermouth on the table, dashing ice cubes across the kitchen floor, and cutting lime wheel garnishes so thick they topple the coupe. You need the right tools of the trade to have any hope of aping the grace of a professional bartender (we miss them dearly), and on behalf of your bar cart, you also need tools that look the part. So instead of piecing together a random at-home setup, go for the visual cohesion of a bartending kit.

    Here, you'll find both basic and more extravagant kits such as Whisky Set or Whisky Gift Set, Wine Tools like Corkscrew and Wine Rack, Cocktail Mixing Glass Set and Cocktail Tool Set With Suitcase. Make the call on the shaker versus mixing glass, how much physical space you can dedicate to the cause, and whether your drinking habits really require the addition of a muddler. If you don't know a 1x2oz. jigger from the can opener under the sink, you can read up on all the traditional bartending tools in our home bar guide. And if you don't know any cocktail recipes, well, get to studying. From toil comes great reward and such a nice, harsh-mellowing buzz.

    In just a few years, the bar industry will be radically different. It is a booming business. With the cocktail renaissance in full swing, more people are looking for quality drinks and bars that can provide them. This has led to an influx of new bars opening up across the country, as well as many bartenders looking for work. While this is great news for bartenders who want to find a job, it also means that there are now more bars than ever before vying for customers who have limited time and money.

    It is necessary to have these epuipments in a bar like Bar Set, Matel Cup & Mug, Automatic Wine Corkscrew,Wine Stopper and of course, bartender tools. There are Bartender Tools You'll Need. A cocktail strainer is a utensil used to remove solids from cocktails and other liquids. This tool is typically employed after shaken drinks, catching any fruit bits or ice in the liquid before it goes out.

    A stirring spoon, also known as a cocktail stirrer, is the perfect tool for bartenders to measure, layer and stir cocktails. Its stainless steel construction is sturdy and can be washed clean with soap and water. Not only does it give your customers their drinks their preferred taste but it won’t affect the flavor of your customer's.

    A cocktail shaker is also on the list ofvaluable bar accessories that you should never go without. The item is useful when mixing cocktails such as cosmopolitans and martinis. It eases the idea of having to come up with a perfect blend that has balanced flavors. It is the best choice if you are looking for something much cheaper than a cocktail mixer as well. Most bartenders and mixologists use it when making a single cocktail. What makes it even more remarkable is that you can use it to make both non-alcoholic and alcoholic drinks. You should, however, make sure you rinse the shaker well enough when switching between those two categories.

    The item enables you to diversify drinks and makes it easy to explore newrecipes. There are also various types of cocktail shakers for you to pick from, including Parisian, Cobbler, and Boston cocktail shakers. The easiest shaker to use is the Cobbler or the 3-piece cocktail shaker. That is because it comes with a lid and a strainer making the mixing fun. When picking a type of shaker, you should ask yourself what your level of expertise is and how you like your cocktails. If you are an expert, consider the Boston shaker.

    Aluminum windows and doors have become increasingly popular for both commercial and residential buildings. Aluminum window frames can be made to match almost any color and home style. They can also be made in a range of different configurations including Aluminium Casement Windows, double-hung windows, Aluminium Sliding Windows/doors, awning windows, fixed windows, and lift and slide doors. Here are some reasons why you should choose aluminum.


    Aluminum windows are far less prone to warping; they are weather-proof, corrosion-resistant and immune to the harmful effects of UV rays, ensuring optimal performance with a long lifespan. Their strong window frames will last longer than wood and vinyl frames.

    Variety of Color Options

    Aluminum windows can be powder coated or anodized in thousands of colors. The only limitation in color is your imagination.

    Energy Efficient

    Because aluminum is light, malleable and easy to work with, manufacturers are able to produce window frames that offer high levels of wind, water, and air-tightness, which means exceptional energy efficiency.

    Cost efficient

    Aluminum windows are far less expensive than wood frames. They do not leak; therefore, they can save a ton of money on energy bills.

    Low Maintenance

    As opposed to wood, aluminum does not warp or decay. Additionally, paint touchups are not needed. Aluminum is strong enough to bear the load of window lintels with minimal reinforcement. Aluminum windows are virtually maintenance free.

    Better Operability

    Aluminum is a durable substance and will keep its shape over time. Therefore, aluminum windows and doors will continue to open and slide smoothly over the years.

    Noise Proof

    Aluminum windows are much better at stopping noise than vinyl windows. Since they are three times heavier and many times stronger than Vinyl. Also, aluminum windows are best when you're opting for the soundless feature due to the fact that they can support heavier glazing than other solutions.

    Safety Features

    The linkage hardware around the window sash and the handle operating make the window have excellent safety and security. Also, aluminum windows are highly resistant to forced entry and have high-quality multipoint locking mechanisms, which makes it impossible for people to break-in.

    Pressure washing including Electric Pressure Washer and Gas Pressure Washer has quickly become one of the preferred methods of cleaning a variety of surfaces in both residential, commercial, and business locations. From sidewalks and patios to residential home exteriors, pressure washing is suitable in a number of different cleaning contexts. Pressure washing is an excellent way of maintaining or restoring the look of the home, with many realty agents recommending that potential sellers invest in a pressure wash as a way of boosting the curb appeal and listing price of their home. When used to treat concrete sidewalks, pressure washing is a quick, easy, and efficient way of removing all manner of dirt or salt deposits that contribute to surface weathering. If you are worried about having to invest time and energy replacing another stained deck, then pressure washing may be your answer, as it is one of the best ways to boost their longevity. Read on to learn about the many benefits of pressure washing!

    Pressure washing is easy for everyone.

    Conventional cleaning tasks typically require a lot of time, energy, and elbow grease. With pressure washing, there is no need to scrub and strain to unsettle stubborn debris. Save your back and joints the effort. Pressure washers let you maintain a strong upright posture and direct the force of the water towards unwelcome stains. The set-up required for a pressure washing treatment is also quite simple, involving about as many steps as it would require to find soap, sponges, and fill a bucket. Simply affix a water hose to the pressure washer unit, and either plug it in or add fuel to its power source to begin.

    Pressure washing saves serious time.

    Compared to regular cleaning methods, pressure-washing is an anti-bacteria blitzkrieg. When you invest in a professional pressure washing, you are cutting out the need to gather materials, prepare a cleaning solution of appropriate strength, and undergo a rigorous half-day or more of scrubbing. Pressure washing eliminates the need for time-consuming ladder work, allowing you to simply point the nozzle towards hard-to-reach areas.

    Pressure washing keeps your family safe.

    Your home houses more than family. On decks, exterior walls, and sidewalks you will find a number of unique contaminants, varying in severity from dirt to harmful mold. Pressure washing blasts these potentially harmful substances away, keeping your family breathing the purest air possible. Pressure washing away algae or other slippery substances also minimizes your family's risk of slips or falls at home. Furthermore, regular pressure washing treatments are considered part of an overall preventative maintenance effort that can keep your home safe and in-shape. Keeping your home clean hinders the premature decay of your porch, driveway, or deck, improving safety outcomes.

    Pressure washing boosts curb appeal.

    When realty agents are asked by motivated sellers how they can distinguish their homes from countless other listing competitors, they often reply that increasing curb value is an effort well-invested. Curb appeal allows your home to stand out from other home listings, and will draw in many more interested buyers when it comes time to host a viewing. Many of the actions taken to improve curb appeal can be completed faster and more thoroughly using a pressure washer. Boosting curb appeal is often done by shaping up the condition of the driveway and bordering sidewalks, or by cleaning unattractive mildew off of the home’s exterior. Pressure washing can take care of all of these tasks in a breeze, preserving your time and energy for more pressing issues faced when entering in to an unruly realty market!

    Pressure washing is easy on the environment.

    Heavy-duty cleaning is commonly associated with the application of harmful chemical cleaners. These cleaning solutions can be very effective, but typically enact a heavy toll on the environment. Pressure washing does not introduce any harmful chemicals into the environment. Pressure washers work by blasting water at high velocity, and the power of this water stream is often sufficient to lift stains and mildew without the need for harmful chemicals.

    Pressure washers also use less water when compared to the amount used by a garden hose tackling the same kind of job. The amount of force applied by pressure washers means that much less water will be needed overall, with some estimates suggesting that as much as 75% of water is saved using pressure washing. This is because a pressure washer expels water at roughly 50 times the force of a garden hose. This allows the smallest amount of water to be granted the greatest amount of cleaning power. 

    Except for the pressure washer, Sprayers also play an effective role in vleaning or house keeping, like Electric Sprayer, Power Sprayer and Manual Sprayer.

    Towels are the most commomly used products in our dailt life. A towel is a piece of absorbent fabric or paper used for drying or wiping a body or a surface. It draws moisture through direct contact.

    In households, several types of fabric towels are used, including hand towels, bath towels, and kitchen towels. At the beach, people use beach towels. Paper towels are provided in commercial or office bathrooms via a dispenser for users to dry their hands. In households they are used for minor, precision, or particularly dirty jobs of wiping, cleaning, and drying.

    Nothing feels better than wrapping yourself up in a cozy towel after you get out of the tub or shower. If your towel is feeling rough or isn't drying you off quickly, chances are it's time for an upgrade. The problem is there are so many bath towels to choose from at a wide range of price points, so it's not exactly easy to shop for bath towels, especially when you're unsure of how they'll hold up over time.

    If you want a super soft, ultra-absorbent towel, look for 100% cotton with dense, plush loops of yarn on the surface. You can also look at fabric weight, which is shown in GSM. Over 600 GSM is considered heavy, so these will typically be the most plush. Lighter towels like waffle weaves or ribs weren't typically as soft in our test.

    If you want a towel that's quick-drying and more durable, consider a cotton-poly blend or a lighter fabric with a low pile (short loops). Fluffy loops help the towel feel soft and absorb water, but they can take longer to dry and may show more wear from laundering.

    As for the stuff for bath or bedroom, there are also many tpyes except for the towel.

    Visit a bed and bath store, and you'll find aisle after aisle devoted to every type of bedding. There are comfortable, soft sheets that make sliding into bed a joy; blankets that warm up chilly winter nights, and many different types of bedding toppers such as Mattress Toppers, Pillows & Pillow Cases and Bathrobe. The last category is where confusion might set in—comforter, duvet cover, quilt, bedspread: What’s the difference, and why should you choose one over the other, anyway? While sheets and blankets are mostly functional, the bedding topper has a more decorative purpose—it sets the pace for your bedroom’s style and feel. So when it's time to give your bedroom a new look, it helps to know which type of topper is the best choice for your space.

    Typically, comforters are defined as thick bedding toppers filled with down or a synthetic substitute. Many comforters are sewn-through or quilted to keep the filling in place, but unlike a quilt, a comforter’s stitching is not ornately patterned. The amount and type of fill determine how much warmth a comforter provides. Probably the most popular type of bedding topper in the U.S., you can find comforters in just about any theme, color, style, or design you desire. Cotton, cotton blends, and synthetics are the most common fabrics. Comforters are usually warm enough to use without a blanket underneath. Often, you'll find comforters sold as a set with matching shams.

    Without doubt, these toppers are also highly needed in the hotel. Therefore, a lot of similar products specially designed for hotel come into being. Except for the product mentioned above, there are also Hotel Linen and Hotel Fabric.

    Aluminum (Al), also spelled aluminium, chemical element, a lightweight silvery white metal of main Group 13 (IIIa, or boron group) of the periodic table. Aluminum is the most abundant metallic element in Earth's crust and the most widely used nonferrous metal. Because of its chemical activity, aluminum never occurs in the metallic form in nature, but its compounds are present to a greater or lesser extent in almost all rocks, vegetation, and animals. Aluminum is concentrated in the outer 16 km (10 miles) of Earth's crust, of which it constitutes about 8 percent by weight; it is exceeded in amount only by oxygen and silicon. The name aluminum is derived from the Latin word alumen, used to describe potash alum, or aluminum potassium sulfate, KAl(SO4)2.12H2O.

    Aluminum is added in small amounts to certain metals to improve their properties for specific uses, as in aluminum bronzes and most magnesium-base alloys; or, for aluminum-base alloys, moderate amounts of other metals and silicon are added to aluminum. The metal and its alloys are used extensively for aircraft construction, building materials, consumer durables (refrigerators, air conditioners, cooking utensils), electrical conductors, and chemical and food-processing equipment.

    Pure aluminum (99.996 percent) is quite soft and weak; commercial aluminum (99 to 99.6 percent pure) with small amounts of silicon and iron is hard and strong. Ductile and highly malleable, aluminum can be drawn into wire or rolled into thin foil. The metal is only about one-third as dense as iron or copper. Though chemically active, aluminum is nevertheless highly corrosion-resistant, because in air a hard, tough oxide film forms on its surface. There are also other aluminum contents like 1050 Aluminum, 1060 Aluminum, 1100 Aluminum, Alloy Aluminum, 2A12 Aluminum, 3003 Aluminum, 5052 Aluminum, 5083 Aluminum, 5754 Aluminum, etc.

    Aluminum is an excellent conductor of heat and electricity. Its thermal conductivity is about one-half that of copper; its electrical conductivity, about two-thirds. It crystallizes in the face-centred cubic structure. All natural aluminum is the stable isotope aluminum-27. Metallic aluminum and its oxide and hydroxide are nontoxic.

    Aluminum is slowly attacked by most dilute acids and rapidly dissolves in concentrated hydrochloric acid. Concentrated nitric acid, however, can be shipped in aluminum tank cars because it renders the metal passive. Even very pure aluminum is vigorously attacked by alkalies such as sodium and potassium hydroxide to yield hydrogen and the aluminate ion. Because of its great affinity for oxygen, finely divided aluminum, if ignited, will burn in carbon monoxide or carbon dioxide with the formation of aluminum oxide and carbide, but, at temperatures up to red heat, aluminum is inert to sulfur.

    Aluminum can be detected in concentrations as low as one part per million by means of emission spectroscopy. Aluminum can be quantitatively analyzed as the oxide (formula Al2O3) or as a derivative of the organic nitrogen compound 8-hydroxyquinoline. The derivative has the molecular formula Al(C9H6ON)3.

    Greeting cards are an illustrated message that expresses, either seriously or humorously, affection, good will, gratitude, sympathy, or other sentiments. Greeting cards are usually sent by mail in observance of a special day or event and can be divided into two general classifications: seasonal and everyday. Seasonal cards, also called Holiday Cards, include those for Christmas, Valentine's Day, Mother's Day, Father's Day, Easter, graduation, Halloween, and St. Patrick's Day. Everyday cards include those commemorating birthdays, anniversaries, or births; cards of condolence, congratulations, or friendship; as well as get-well cards, gift cards, bon voyage cards, and thank you cards.

    Modern greeting cards are usually of stiff paper or cardboard, but some are made of cloth, leather, celluloid, vellum, metal, or even wood, clay, cork, or other materials. Size is determined by common usage, the availability of suitable envelopes, ease of mailing, and the system of grading according to price and quality. There are also some kind of cards with neoteric design like Laser Card and 3D Greeting Cards. Somenody even use Sticker and Washi Tape to decorate the card. Extreme exceptions include an inscribed grain of rice presented in 1929 as a Christmas greeting to the prince of Wales and a Christmas card sent to Pres. Calvin Coolidge in 1924 that was 21 by 33 inches (53 by 84 cm). The imprinted messages on cards may vary in length from a brief word or two to 100 words or more in prose or verse.

    The exchange of illustrated greetings among friends dates from ancient times. In Egypt the new year was celebrated by the exchange of symbolic presents, such as scent bottles and scarabs inscribed au ab nab ("all good luck&quotWink. The Romans exchanged strenae, originally branches of laurel or olive, frequently coated with gold leaf. Symbols of seasonal good will, such as a Roman lamp impressed with the figure of Victory surrounded by strenae, were inscribed with Anno novo faustum felix tibi sit ("May the new year be happy and lucky for you&quotWink. The acknowledgment of the new year with exchanges of good will continued in Europe through the early days of Christianity.

    Speaking of cards, I thought of another paper product that is used most often - Notebook.

    We all saw it over and over during the pandemic year: In the face of remote and hybrid learning, students spent hours tethered to iPads and Chromebooks, all day, every day. While such technology thankfully allowed for online learning that would have been inconceivable a decade ago, excessive screen time has been linked to a host of deleterious effects.

    Students using devices to take notes are often bombarded with updates, messages, and notifications, plus they’re distracted by the ever-present temptation to search the web. Authentic learning, however, requires concentration and deep, uninterrupted immersion in a topic.

    In a bid to reclaim some balance between digital and analog learning, Many students are required to use paper notebooks this coming year. Paper notebooks can help draw young people's attention away from screens, and they offer several educational benefits.

    Using a notebook compels students to become more deliberate in the organization and presentation of their notes. Plenty of apps provide ways to create and manage notes, but I’ve found that using notebooks places more responsibility on the students to find, adapt, and stick to a method that works best for them. And there is always a tpyes of notebook to fit your love of using habit. For example there are PU Notebook and Spiral Notebook. If that is not enough, it is very normal to add some Sticky Notes on the notebook as a additonal content.

  How does a miniature circuit breaker actually work?
Posted by: alumniii - 12-01-2021, 01:07 AM - Forum: My Forum - No Replies

How does a miniature circuit breaker actually work?

    Miniature circuit breakers (MCBs) ensure electrical safety in homes, offices, and other buildings as well as for industrial applications by protecting electrical installations against overloads and short circuits. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. Warranting reliability and safety for people and assets, MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

            Just imagine you live in an apartment built maybe sometime in the 60s. You抳e just decided to get your annual spring clean over and done within record time tonight. In preparation, you抳e compiled your favorite MP3 playlist on your PC and it抯 being streamed in all rooms. You抳e filled the dishwasher and turned it on, the washing machine is full of clothes and you抳e flicked the switch, you抳e pulled the vacuum cleaner out of its corner and plugged it in.
            Not long after, you hear a quiet 慍LICK?from the corner (or, in the case of older apartments, from out in the hallway). The lights are out, the music is only playing in a couple of rooms or not at all, the washing machine and the dishwasher are off and the vacuum cleaner has fallen silent.
            You抮e annoyed, and you try to figure out what抯 going on. Usually, 憈he cause?can be located quite quickly: that 憈hing?in the box on the wall is off. So, you switch it back on, and off you go. Moments later, the circuit breaker once again clicks to cut off the overload. In a pinch, you might even get the bright idea that you might be able to jam the switch in the ON position so that you can just finish vacuuming your apartment.
            What happened?
            Annoyingly, doing that won抰 let you effectively clean your apartment nowadays. Our ABB miniature circuit breaker will, thankfully, protect your wires from both overloads and short-circuits even if the switch has been forced into the ON position, due to what we call a 憈rip-free?MCB. Even if your finger keeps the switch in the on position, the internal mechanism will trip and ensure safe disconnection of the overloaded circuit.
        What exactly does an MCB do?
        The short answer: it protects wires from overloads and short-circuits. When we look on the inside of an MCB we can see how that actually works.
        While electricity has become an indispensable component of our lives, the fact is, it comes with its own hazards to human life and property. Electrocution and fire being the two major risks associated with electricity, one cannot afford to be negligent when it comes to insulating equipment.
A Residual Current Circuit Breaker (RCCB) is an important safety measure when it comes to protection of electrical circuits. It is a current sensing device, which can automatically measure and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity.
        Principle behind RCCB
        RCCB works on the principle of Kirchhoff抯 law, which states that the incoming current must be equal to the outgoing current in a circuit. RCCB thus compares the difference in current values between live and neutral wires. Ideally, the current flowing to the circuit from the live wire should be the same as that flowing through the neutral wire. In case of a fault, the current from the neutral wire is reduced, the differential between the two known as Residual Current. On spotting a Residual Current, the RCCB is triggered to trip off the circuit.
        A test circuit included with the Residual Current device ensures that the reliability of RCCB is tested. When the test button is pushed, the current starts to flow through the test circuit. As it creates an imbalance on the neutral coil of the device, the RCCB trips and supply is disconnected thereby checking RCCB抯 reliability.

        Benefits of RCCB
        Provides protection against earth fault as well as any leakage current
        Automatically disconnects the circuit when the rated sensitivity is exceeded
        Offers possibility of dual termination both for cable and busbar connections
        Offers protection against voltage fluctuation as it includes a filtering device that guards against transient voltage levels.
        Moulded Case Circuit Breaker is an electromechanical device which protects a circuit from overcurrent and short circuit. It provides overcurrent and short circuit protection for circuits ranging from 63 Amps up to 3000 Amps.
            The primary function of an MCCB is to provide a means to manually open a circuit and automatically open a circuit under overload or short circuit conditions. The overcurrent, in an electrical circuit, may result from short circuit, overload or faulty design.
            It is generally installed on the secondary side of transformer stations (main switch or for protecting individual branches). In industry, we can use it in switchgear or for protecting the motors as well we have big requirements in shipbuilding. For building applications, you can find it as the main protection switch.
        The Molded Case Circuit Breaker is a specific type of circuit breaker.
        NEMA defines Molded Case Circuit Breaker as devices designed to open or close a circuit by nonautomatic means and to open the circuit automatically on a predetermined overcurrent without damage to itself when properly applied within its rating.
        The term 搈olded case?simply refers to the construction of the circuit breaker and refers to the fact that the circuit breaker is an assembled unit in a supporting housing of insulating material.
        MCCB vs Fuse
        MCCB is an alternative to a fuse since it does not require replacement once an overload is detected.
        Unlike a fuse, an MCCB can be easily reset after a fault and offers improved operational safety and convenience without incurring the operating cost.
    What are circuit breakers?

        Essentially, circuit breaker is lockdowns but for a limited amount of time. They are designed to break the chain of infection, and bring the infection rate down. It抯 hoped that circuit breakers will help to reduce pressure on health services as hospitalizations due to Covid-19 rise.
        This is crucial for the U.K., which has the third-highest number of coronavirus cases in Europe, with its tally now standing at just over 744,000 cases with 43,816 fatalities, according to data from Johns Hopkins University. It is currently battling a dramatic second wave of infections, like the rest of Europe, particularly in northern England.
        On Monday, 18,804 new daily infections were reported, up from 16,982 on Sunday. The seven-day average number of cases on Oct. 16 was 17,649, according to government data, compared to 14,588 a week before.
        Scientists advising the government seem to favor circuit breakers, as does the opposition Labour Party, with both encouraging the government to implement a mini-lockdown.
                                        While technology has improved over years, the primary means of controlling electrical circuits remain the same. Among these are contactors , and this article examines the different types of contactors and how they work. It also looks at the differences between contactor and relay , AC contactor and DC contactor.
                                        What Is a Contactor?
                                            A contactor is an electromechanical switch whose function is to make or break the connection between the power supply and the load. The contactor is electrically controlled and usually powered at a much lower level than the switched circuit. For example, you would have a 24-volt coil electromagnet that controls a 230-volt motor switch.
                                            A contactor抯 applications include controlling electric motors, thermal evaporators, lighting, capacitor banks , heating, and other electrical loads. Contactors range in size and capacity. You have those that you can easily lift with your hand to massive ones measuring about a meter on the side. You also have those with a breaking current ranging from a few amperes to thousands of amperes and those from 24V DC to many kilo volts.
                                        Types of Contactors
                                        Knife Blade Switch
                                            It is the oldest type of contactors and uses ON and OFF electric motors. The knife blade switch consisted of a strip and a lever. The lever serves to pull the metal strip up and down, making this contactor a manual operation. It has several shortcomings which led to its discontinued use. These challenges include
                                            High incidences of arcing led to a short life span for the contactor
                                            Had safety risks
                                            Was vulnerable to moisture and dirt
                                            Double Break
                                        Manual Contactor
                                            This contactor was a replacement and improvement on the knife blade switch. It, however, still features manual operation. Other key features are
                                            Double break contacts, which can open the circuit in two places simultaneously, providing more current in smaller spaces.
                                            Properly enclosed unit protecting the inner parts
                                            Safer operation
                                            Smaller size
                                        Magnetic Contactor
                    This is the latest contactor design and is the most advanced of them all. It is commonly used in industrial applications due to its features like
                    It works automatically
                    Offers the safest operation
                    Uses the least amount of control current to open and close a circuit.
                    How Does a Contactor Device Work?
                                                            To understand the contactor working, you need to know the various parts of a contactor. There are three essential components of a contactor;
                                                            The coil/electromagnet
                                                            The frame or enclosure
                                                        Coil or electromagnet
                                                            The coil provides the driving force in a contactor that closes the contacts. It features a coil wound around an electromagnetic core and thus behaves like an electromagnet. The coil has two parts, a fixed one and a movable part with a spring connecting both parts. This structure creates a spring return mechanism.
                                                            A rod called an armature is connected to the movable part. When the coil抯 force is more than the spring抯 force, both contacts connect. When the spring抯 force is more than the coil抯 force, the contacts disconnect.
                                                            The input of the contactor coil could either be AC or DC. This current comes from an external control circuit for the contactor and serves to excite the electromagnetic core. For AC magnetic contactor, soft laminated iron is the electromagnetic core material. It helps reduce the eddy current loss. In DC contactors, solid steel is the material for the electromagnetic core as the issue of eddy current does not arise.
                    Magnetic Starter
                    Magnetic starters are the most common type of starter & they are mostly used for high power AC motors. These starters operate electromagnetically like a relay that breaks or makes the contacts using magnetism.
                    It provides a lower & safer voltage for starting & also includes protection against low voltage & overcurrent. During the power failure, the magnetic starter automatically breaks the circuit. Unlike manual starters, it includes automatic & remote operation that excludes the operator.
                    The magnetic starter consists of two circuits;
                    Power circuit; this circuit is responsible for supplying power to the motor. It consists of electrical contacts that turn ON/OFF the power supplied from the supply line to the motor through overload relay.
                    Control circuit; this circuit controls the contacts of the power circuit to either make or break the power supply to the motor. The electromagnetic coil energizes or de-energizes to pull or push the electrical contacts. Thus providing a remote control for the magnetic starter.
                    A overload thermal relay works on the heat produced by the excessive overload current. The heat produced by the overload current is utilized to trip the motor circuit. These are mostly used for protection of low-voltage squirrel cage induction motors or DC motors of lower output rating. As a professional manufacturer, we will continue to provide customers with excellent quality products.

The 4 Benefits of Using PPR Pipes for Drinking Water

    PPR pipes are made of polypropylene random copolymer plastic and it is commonly a cylindrical pipe and straight. They are lightweight which makes them easy to transport and are usually offered in green and white. The PPR pipes are also known for having walls that are thicker than PVC pipes. The PPR piping system comes with fittings, valve, fusing machine, and other accessories that are available for every size of the pipe.  They are safe to use and are non-toxic, that抯 why this is the best choice when it comes to drinking water piping systems.

    Let抯 take a dive-down look at the benefits of PPR Pipes for drinking water and why it is safer.

    1. Smooth Inner Surface

    Compared to other traditional types of pipes, the PPR pipes have a very smooth inner wall or surface. Because of the smooth walls, the pipes only have a small effect when it comes to frictional resistance. It also reduces the pressure during transporting and distributing the fluid. On the other hand, the PPR pipes do not flake, unlike the metal pipes, that抯 why this is a safer choice for drinking water.

    2. Long Term  Service

    We want a piping system that is safe, and other than being safe we want it to have a long service life. For over 50 years, the PPR piping system has been functional and still has that wide range in temperature. It can endure the hot temperature and at the same time, it can withstand cold temperatures without getting cracks or breaking that will lead to water leaks.

    3. Heat and Cold Resistance

    PPR is designed to be a versatile piping system for potable water that can be used in different industries, such as hospitals and hotels. And PPR piping system has good heat resistance that can reach up to 80 (and above) degrees celsius. It can also withstand cold temperatures, mostly installations in cold weather where other pipes are prone to damages that cause water leaks. This is why PPR is the best choice for drinking water.

    4. Non-Toxic

    Toxic chemicals that come from our water supply is a threat to our health, but pipes and fittings made from PPR are harmless raw materials. Thus, it will not carry toxic substances that will affect the health of people drinking water from it. And it抯 not only safe for our bodies, but it is also safe for the environment. Since they are non-toxic, any production or installation of the PPR piping system will not cause pollution.

    Overall, PPR pipeline is safer and has more advantages than metal pipes which is why PPR is suitable for our drinking water. After all, we want our family to be safe and healthy at the same time.

    We hope that this article has helped you in making a decision on which pipes you抣l use for drinking water.

    PPR Fittings: Know More About Them

    PPR Fittings are the most important part of the PPR piping system because their purpose is to make different applications for water connection, whether in the building or at home. They may seem complicated because of their various appearances, but they are easy to remember!

    In this article, we will help you understand the functions of PPR fittings and its applications.

    1. Elbow

    If you need to turn your pipes in another direction, use the elbow fitting. This helps you direct the flow of the water, may it be to the left or right, upward or downward direction. They are available in different angles, depending on how you need it.

    Usually, the elbow fitting is meant for pipes that have the same diameter sizes, so always check the sizes before you purchase this fitting.

    2. Elbow Reducer

    An elbow reducer is a type of pipe fitting that joins two pipes of various sizes together. It connects two different pipe sizes that need an angled direction. l

    3. Coupling

    Couplings are used to connect two pipes together.

    What Is Poly B Plumbing, and What Does It Mean If You Have It?

    Poly b plumbing used to be a household name, but that's no longer the case. If you've heard that you have this type of plumbing and want to learn more about what that means, read on. We've laid out a guide on what pb pipe is, how to tell if you have it, and what you should do if you find this piping in your home.

    What is poly b plumbing?

    Polybutylene plumbing is also known as poly b plumbing, poly b pipe, or pb pipe. This plastic piping was used frequently as a water supply line in homes from the 1970s up until the mid-1990s. It was originally used as a substitute for copper piping because of its low cost, flexibility, and easy installation.

    However, over time, the use of poly piping was eventually discontinued. Originally, the fault was thought to be in the brass fittings, which were used to connect one pipe to another. If the fittings were installed too tightly, they would crack and cause leaks.

    Eventually, though, it was also discovered that hot water and chemicals like chlorine can also melt or corrode the Pb piping system. To make matters worse, these pipes will look fine on the outside as they are degrading on the inside, so there was no way to tell when a leak would occur.

    How to tell if you have pb pipe

    If you live in a house built between 1970 and 1996, there's a chance your home might have plastic piping. Luckily, the International Association of Certified Home Inspectors (InterNACHI) has provided tips for identifying poly piping:

            Poly b piping is usually a gray color. However, it may also be white, silver, black, or blue. Blue pb, in particular, is primarily used outdoors.
            It's usually stamped with the code "PB2110."
            Unlike copper pipe, poly pipe is flexible. Sometimes it can even be curved.
            It's a half inch to an inch in diameter.
    Notably, sometimes poly b pipe is confused with pex pipe. Pex piping is usually used with radiant heating systems and can be either white, red, or blue in color. While there are also safety concerns surrounding pex piping, its colors are noticeably brighter than those you would find on pb piping. Those tubes are also much more flexible, so much so that they are even able to coil.

    HDPE Pipe Fittings

    The HDPE fittings can be performed in several ways as described below. It should be noted that based on the type of the fittings included in the specifications of the design one should do pipe fittings in different parts of the plan.
HDPE pipes are usually produced with two simple ends. Therefore, in order to establish a connection between the two branches, it is necessary to connect one simple end of a branch to the other simple end with a connection to each other. The various methods used to connect HDPE pipes, accessories and valves, are as follows:

    1-    Thermal Butt (Butt fusion)

    2-    Thermal bushing

    3-    Electro Fusion

    4-    Flange

    5-    Extrusion

    6-    Bolting

    7-    Rubber gasket latching

    It should be explained that all of the above methods are currently not applicable due to the lack of production of the necessary supplies in the country, but the explanations needed to use them, if produced, are given. The consultant engineer will determine the pipe connection method according to the facilities available at the time of work in the specifications of the design. At the moment, the butt thermal connection is used for the main projects of HDPE piping and the flange connection is used for special fittings. The contractor is required to provide arrangements, and qualified personnel for any method specified in the layout specifications, and, accordingly, proceed with the connection.

    HDPE Pipe Fittings

    HDPE pipeline Adaptable for all piping, these fittings are used on HDPE pipe to change direction, insert a lateral or tee, or simply to cap off an end of a line.

    polyethylene pipe fittings

    polyethylene pipe fittings are used in all polyethylene pipelines and projects that have been used in some way as polyethylene tubes, and the type of polyethylene pipe fittings will vary according to the type of project. Polyethylene pipes are used in sewage transfer, water supply, fire extinguishing systems, covering cable and gas applications, which will vary depending on polyethylene pipe applications.

  What is the difference between hydraulic bending machine and CNC bending machine?
Posted by: alumniii - 12-01-2021, 12:57 AM - Forum: My Forum - No Replies

What is the difference between hydraulic bending machine and CNC bending machine?

    Casting technology has a long history in our country. The overall cost of the workpiece is very low, mainly by smelting the metal into a liquid, and then pouring the liquid into a specific forming mold. After the liquid metal is cooled, a shaped casting is formed. The casting technology is to burn some steel material in a charcoal fire, and then quickly pull the red steel out and put it into an air hydraulic hammer for forging.

    Bending machine blade mould

    The reason why CNC bending machine molds choose forging instead of casting is because casting generally requires steel mills to produce rolled blanks, and steel mills are willing to produce when there are many standard parts, but standard parts for CNC bending machine molds Generally not many, it is not very cost-effective to use castings in general.

    Numerical control bending machine molds also have high requirements for strength. Castings are prone to bubble formation during the production process, which makes the strength not as good as forgings. Forgings are forged by air hammers, and the interior will be more rigid, so the strength will Larger, so CNC bending machine molds generally choose forging rather than casting.

    The CNC bending machine is an ordinary hydraulic bending machine with a CNC operating system. It is an upgraded product of the ordinary bending machine. Frequent process conversion can reduce the labor intensity of the operator. However, the operating skill of the operator is higher than that of the ordinary hydraulic press brake.

    Compared with the hydraulic bending machine, the CNC bending machine is characterized by its CNC operating system. This is an upgrade to the ordinary bending machine, which reduces the labor of the operator and enhances the processing efficiency. But at the same time, the operating requirements and skills of CNC bending machines are much higher than those of hydraulic bending machines, and they are relatively complex. The CNC bending machine has a multi-step programming function, which can realize multiple automatic operations and complete the one-time processing of multi-step parts.

    In the hydraulic bending machine, the coil is energized by the wire, and the gravitational force is generated on the pressure plate after the energization, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the electromagnetic clamping, the pressing plate can be made into a variety of workpiece requirements, and the workpiece with side walls can be processed.

    The hydraulic bending machine includes a support, a workbench and a clamping plate. The workbench is placed on the support. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a housing, a coil and a cover. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the wire is energized to the coil, and the gravitational force is generated on the pressing plate after being energized, so as to realize the clamping of the thin plate between the pressing plate and the base. Due to the electromagnetic clamping, the pressing plate can be made into a variety of workpiece requirements, and the workpiece with side walls can be processed.

    CNC bending machine and CNC folding machine

    CNC bending machine and CNC folding machine in sheet metal forming, from the following six aspects of the characteristics of the comparison:

    (1) different forming principles

    Bending machine -- bending Angle is controlled by controlling the amount of upper and lower pressure. When bending, the short side is included. Operators need to lift most of the materials on the outside. Edge folding machine - after the plate is placed flat on the work table, the edge holder is pressed down to fix the plate, and the edge holder is flipped up and down to achieve the edge folding. In all the edge folding processes of an edge, manual positioning and auxiliary turning and positioning work are no longer needed.

    (2)The bending accuracy is different

    Bending machine -- the dimensional accuracy of the control is the short side dimensional accuracy of the positioning of the rear stop. After the completion of bending, the final error accumulates to the inner space size. At the same time, because the bending Angle is controlled by the pressing amount of the upper die, the Angle is related to the thickness of the material. Folding machine -- the size precision of the control is after the first folding is finished, the first edge is taken as the positioning benchmark, and the final control size is exactly the inner space size required by the customer. At the same time, the bending Angle is directly controlled by the flanging Angle, which has nothing to do with the thickness of the material.

    (3) material surface damage problem

    Bending machine - when working, the material will generate relative movement in the lower die, leaving indentation without surface protection.When bending large workpiece, need to turn over and move many times, the process will inevitably produce scratches. Crimping machine - when working, the crimping beam cutter and the crimping beam cutter do not move relative to the material, thus completely avoiding surface damage.Large workpiece in bending, because the plate is flat processing, at the same time a positioning can be completed on one side of the workpiece all processing, completely avoid surface damage.

    ?The skill level of workers is different

    Bending machine - bending workers of a relatively higher level of technical requirements. Folding machine -- programming can be realized intuitively by drawing with fingers or offline programming can be realized by engineers using software and importing processing program with USB or network connection. After programming, the main work of workers becomes simple loading and unloading work without skilled bending workers.

    ?Cutting tools configuration

    Bending machine - different thickness, shape of the product, need different up and down mold, in the realization of some special bending (such as arc) requirements, need to change the tool or transfer to another machine tool to achieve, increase the transfer of semi-finished products and temporary storage work. Folding machine - through the configuration of rotatable beading beam, while installing two sets of beading beam tools, to achieve the simi complete all bending procedures, for arc bending or other special bending requirements, basic need not change the tool, just in the program to make changes can be completely achieved.

    ?The knives' service life

    Bending machine - because of the relative movement of the workpiece in the die, the tool will wear, maintenance or replacement. Flanging machine - basically avoids the relative motion between the material and the cutting tool.

    ?Drive system

    Bending machine - hydraulic drive, bring more maintenance work and easy to be affected by environmental factors. Flanging machine -- adopts all-electric drive design, reduces the maintenance workload and is independent of the use environment, so as to achieve higher bending accuracy

    ?Disadvantages of the hemming machine

    1) due to different bending principles, R Angle of the edge bender is larger than that of the bending machine;

    2) limited by the supporting table, the workpiece that flips down on both sides cannot be processed;

    3) the workpiece size is limited by the pressing area of the upper mold, and the workpiece smaller than the size of the pressing area cannot be processed;

    4) the efficiency is not as high as the bending machine;

    5) due to the structural characteristics and mold diversity of the bending machine, some complex shapes can be simple to achieve through the bending machine, relatively speaking, the  flexibility of the folding machine is poor;

    6) folding machine is widely used in Europe and the United States, we are affected by the traditional Japanese processing concept, the general use of bending processing, no better use of folding machine.

    How does the sheet metal bending machine grasp the bending size and how to adjust the mold?

    We all know that the material that we want to bend on the sheet metal bending machine is in compliance with the standard, and we need to have a certain control over the size of the bending, so do you know how to grasp the size of the bending? The main thing is to bend. The following article will give you a detailed introduction. In addition to the bending angle, the mold is also very important. As long as there is no problem with the use of the mold, the bending angle will be no problem. Do you know how the mold should be adjusted? Mainly about the adjustment of the machine, the adjustment of the slider stroke, and the stroke Module adjustment, gap adjustment and angle adjustment, the following is a detailed introduction, let抯 take a look.

    How to grasp the bending size of sheet metal bending machine:
If you want to ensure that the bending size of the sheet metal bending machine is in compliance with the standard, you need to control the bending angle. Then the following is an introduction to the grasping method of the specific bending size:
1. Avoid using sheet metal bending machine to bend the edge alignment, avoid large angle alignment.
2. Preliminary inspection is carried out before formal processing, and cyclic inspection is carried out during processing.
3. In order to avoid accumulative errors, the unfolded size must be measured each time it is processed.
4. Choose a good processing method and a good technical preparation method to simplify the processing difficulty.
5. The bending machine selects the appropriate machine according to the accuracy requirements of the processed product.
6. Do not choose different tools, make sure that the tip of the upper die is on the same straight line before processing.
7. For products whose edges must be bent by a bending machine, the front bending angle must be less than 90 degrees.
8. Determine the accuracy of the measuring instrument before processing.

    Installation and adjustment of the mold for sheet metal bending machine:
When installing the sheet metal bending machine mold, be sure to check the status of the equipment, and then install and debug according to the steps. Pay attention to personal safety when debugging. The following is the detailed adjustment content:
1. Adjustment of the machine
When installing the sheet metal bending machine mold, you must first understand the performance of the machine, turn on the metal bending machine, adjust and check patiently, and see if the machine has previously used dust and iron chips. Prevent unnecessary trouble for later use.
2, adjustment of slider stroke
First check whether the ratio between the thickness of the metal sheet bending machine mold and the upper and lower modules is normal. The general slider needs to be controlled at the switch point of the stroke line. This must be noted, otherwise the mold will not be used normally, but some people still Such mistakes are often made.
3, stroke module adjustment
After adjusting the slider stroke standard, the next step is to adjust the upper limit point of the module. Generally speaking, the module is up to the highest point, and the module and switch must be set. In this way, the staying position of the module can be flowed out, and through some of the above operations, the production efficiency can be greatly increased. In this process, the module also needs to be slowed down. Because the module must be decelerated when it is down to the bottom dead center, which protects the machine and the mold.
4. Adjustment of the gap
Then there is the adjustment of the gap between the molds of the sheet metal bending machine. First, measure the gap between the upper module and the lower module. The reasonable gap needs to be determined according to the sheet to be folded.
5. Angle adjustment
Adjusting the bending angle is also the most important link. The selection of the angle is definitely related to the product requirements. Generally speaking, when bending a 90?mold, the angle must be set. The middle angle must be greater than the angle on both sides. Sometimes it may be tight. You can adjust it The screws on the machine are processed. After the adjustment, if the product does not change the demand, do not modify it again. Then, when bending, use the pressure gauge to calculate the accurate pressure number and adjust the pressure. So as not to cause mold chipping.
