Perforated Sheet and its various applications

Perforated Sheets are also known as perforated metal or perforated screen or stamping plates which are fabricated through sheet metal and metal stamping manufacturing processes. The sheet metal substances include aluminum, steel, stainless steel, brass, bronze and titanium and many more. The materials which are used for perforations are very versatile in nature. From load bearing structural parts to lightweight decorative elements perforated metal offers exceptional opportunities to couple functionality, strength and beauty. The excellent way of achieving objects with sustainable design is done through perforated metal. The perforated sunscreens and sunshades offer the building occupants with privacy which also offers in providing perfect view without blocking it. During the hours of daylight these perforated metal offers natural lighting of comfortable level which also help in redirecting the heat on the HVAC system and also helps in reducing the load. Energy is saved and inferior climate is controlled with the help of perforated facades, canopies and claddings.

Highest open area is provided by the staggered perforation pattern. Holes are aligned in nested or staggered orientation. In straight pattern the hole of perforation are aligned in straight columns or rows. The pattern with end perforation is not solid which appears incomplete and rough at the sheet’s end. The area on the inside, end and side are without perforations in margins perforated pattern. The safe side margins are the perforated patterns which do not have perforations over or on the edge but consists of perforations on the way of the edge. The perforated tooling or tools which are used for perforating various patterns on the metals include punch holder, stripper plate, die plate, punches or pins in interchangeable die sets. Side to side measurement is used for determining the diameter or the size of thee holes or of the shape of perforations. At the end of the sheet the end perforation pattern appears complete or uniform and is solid.

Perforated sheets have a wide range of applications which include fencing and screening, risers and stair treads, furnishings, ceilings, in fill panels, building facades, sunscreens, security ceilings, noise control, HVAC, interior designs and many more. The perforated products are used in almost all sections of industries like in food processing used for grain dryers, bee hives, wine vat, hammer mill screens, fish farming, sorting machines, silo ventilation, threshing machines etc. In manufacturing and mechanical industries these are used for ventilations in casing, tractor engine, ventilation grid etc. These are also used in automotive, energy and chemical industries.

Different Electric Locomotive Parts

 Electric Locomotive Parts include all types of parts used in electric locomotives. These parts are operated by electricity derived from overhead lines or on board energy storage like fuel cell or battery. In 1837, Robert Davidson, the famous chemist built the first electric locomotive. Batteries or galvanic cell were used to power it. Later, Galvani, a larger locomotive was built by him. In 1879, Werner von Siemens at Berlin presented the first passenger train driven by electric. This train reached a speed of 13 kilometers per hour and consisted of series wound motor of 2.2 kilowatt, three cars and other locomotive parts.

There are many Electric Locomotive Parts. Some of which are discussed below-

Brake lever

A handle which is utilized for operating brakes of a train or of a locomotive is called a brake lever. The brake levers of diesel and steam locomotives look alike. In many electric locomotives, a joystick is used instead of a handle. There are various types of brake levers which are used for various purposes. Some of these include-

Dynamic brake- slowing down of a train or limiting the speed of a locomotive is done by a secondary brake instead of emergency brakes which is called dynamic brake.
Lap brake- the brake of the entire train or locomotive is controlled by the main brake which is called the lap brake.
Emergency brake- in emergency situations the brake that immediately stops the entire train or the locomotive is called emergency brake.
Independent brake- the own individual brakes of the locomotives which are used to stop the locomotive is called the independent brake.

Pantograph

The device that is used to power an electric locomotive by collecting an electric current is known as pantograph. These devices are operated to make a connection with a cable or an electrified overhead wire. There are various types of sizes and shapes of pantographs which depend upon the power supply system, power requirements, speed of the train or locomotive etc. The primary parts of a pantograph are lower arm, upper arm and a head. The head is used for current collection which utilizes metalized carbon strips.

Coupler

The locomotives and the rolling stock are connected on a train with the help of a coupler. The types of couplers include hook with buffers, knuckle, connecting rod or hook and magnetic.

Connecting rod

The mechanical parts of a locomotive are connected from one to other with the help of connecting rods.

Cab

The section of the locomotive housing the engineer or train driver or assistant of the driver or firemen for the required operations and controls of the locomotive is called the cab.

Water Coolers serve us with chilled water

Water Coolers are appliances that cool water and dispense it. These coolers are also known as water dispensers. These coolers can be categorized into bottled water coolers and coolers without bottles. Bottled coolers needs self pick up or delivery of water from the vendors in large bottles. Coolers without bottles are hanged or hooked to the supply of water.

Types

There are two types of Water Coolers which include –

Freestanding

 These freestanding coolers have spout fitted on the cooler, where the bottles are placed to dispense water from the device. Worktops of kitchens or table tops are used for placing these dispensers with five liter water bottles installed on it. The water is cooled in these appliances using thermoelectric cooling devices and the water is pushed into the cooling chamber using the air pumps. Countertop appliances are the most advanced coolers which are connected with the main water supply to dispense instant supply of boiling, hot or chilled water.

Wall mounted

The coolers mounted on the wall are connected to the water supply of the building which uses electricity to operate the refrigeration system to chill the incoming water and it also disposes unused water in the water disposal system of the building. The coolers that are wall mounted are also known as drinking fountains or water fountains which serve instant cool water to the user with the help of the storage system in the appliance that stores chilled water. A button is pressed to deliver the water. On top of the appliance a spring loaded valve is present and the button is placed on it which helps the water to be released. The stream of water delivered arches up so that the user can easily drink from the water source. These coolers deliver water from the municipal water supply directly without any filtering or treatment.

Cleaning process of coolers

Water coolers should be regularly cleaned so that healthy service for years is delivered by it and at the same time the cooler should also remain bacteria and germ free. Some very easy steps to clean the coolers include-

• Whenever the bottle is changed the cooler should be cleaned, at least every six weeks.
• The reservoir must be rinsed with clean water after using mild solution to scrub and clean it.
• The drip tray should also be removed and washed with a mild soap and rinsed thoroughly.
• New bottle should be installed after washing the hands. The neck and the top of the bottle should also be cleaned before installing and the expiry date should also be checked.

Indian Carpets Have High Demand All Over the World

Carpets are textile floor coverings which are used for enhancing the beauty of the floor. On the floor the carpets are fixed from wall to wall or the middle of the floor is covered to enhance the surface of the floor. The upper layer of the carpet is called pile which is attached to the back portion of the carpet. The pile of the floor coverings are made from natural fibers or man-made fibers. The natural fiber which is mostly used for making these floor coverings is wool and the most common man-made fiber is nylon.

Indian Carpets

Indian carpets are famous all over the world. The weaving of carpet was introduced in India when the Muslim conquerors, the Ghauris and the Ghaznavids from the West invaded India in the late eleventh century. The art of carpet weaving also flourished during the period of the Mughal emperor, Akbar around 1500 AD. The Persian carpets were patronized by the Mughal emperors. Persian craftsmen were brought to India for their expertise in fine knotting of Persian style. Carpet weaving entered a classical and aesthetic phase during the reign of Shah Jahan and Jahanigir

The northern part of India is famous for carpet industry, especially Kashmir, Agra, Jaipur and Bhadohi. The high compactness of Indian Carpets has made it popular all over the world. The underprivileged sections of the society are uplifted by the establishment of the carpet industry successfully. The rugs of Khariabad are hand woven which are quite impressive. The Khariabad rugs are knotted and hand tufted rugs made usually of cotton and the other materials like chenille, rayon and jute are also used.

Carpet Manufacturers

Carpet manufacturers fabricate carpets with the help of expert craftsmen who make carpets with specialized hand techniques. The contemporary process of fabricating carpets is completed with the help of computerized machines. The most famous handmade carpets are knotted. In the knotted pile carpets, the supplementary wefts are alternatively used with structural weft threads which rise on the surface at right angles. In the tufted carpets the backing materials are used to inject the pile and this is bonded with the backing of a secondary hessian weave. These tufted carpets are sturdy and offer stability.

Carpet Exporters

Types of Coffee Machinery

Coffee Machinery includes the coffee machines that are used in making coffee. These machines are used for brewing coffee based on various types of brewing principles. Generally coffee beans or grounds are placed inside a funnel with a metal filter or paper and this is set over a ceramic or glass coffee pot. Separate chamber is there for pouring cold water which comes to the boiling point by heating and the water is intended to the funnel.




Types

These are different types of Coffee Machinery used for brewing coffee for years. Some of these include-

Vacuum Coffee Maker

Coffee is brewed in vacuum coffee maker utilizing two chambers which have vacuum and vapor pressure to produce coffee. Loeff Berlin invented vacuum coffee maker in the 1830s. These coffee makers are also called siphon or siphon coffee maker or vac pot. Pyrex or borosilicate glass, plastic, metal etc. are used  for making the material of the chamber and the filter can either be screen or a metal rod which is made up of metal, paper, cloth or nylon. The principle of these coffee makers is to heat the lower vessel water until the force is expanded trough the narrow tube to the upper vessel which consists of ground coffee. The heat is removed when all the water has emptied the lower vessel and then the coffee is brewed in the lower part with a strainer.

Coffee Percolator

A coffee percolator is a type of pot which is used in brewing coffee. The water is passed through the coffee grounds and the constituents that are soluble give color, aroma, taste and stimulating properties to the coffee. These coffee percolators are of two types- in one the boiling water is forced through the grounds under pressure into the separate chamber and in the other the boiling cycle continuously goes on till the required strength is achieved utilizing the gravity.

Electric Drip Coffeemakers

In electric drip coffeemakers, the water from the cold water reservoir is admitted using a flexible hose and then passed into the heating chamber or thin metal tube. This metal tube is surrounded by a heating element which is used for heating the water. The siphoning effect and thermally induced pressure is used to heat the water through vinyl riser hose or insulated rubber onto the ground coffee with the help of a spray head. The brew basket contains the ground coffee which is mounted under the spray head. A filter is used to pass the coffee and then the coffee is dripped down the flask.

All types of coffee machines are available online in the shopping carts. One interested in these machines can browse through the web and can directly avail them from the manufacturers.
