Compressors are the most prominent devices used in industries to increase the pressure of gases. The screw compressor is a type of positive displacement compressor which achieves this with a pair of rotors. The gases are taken inside the compressor using suction valves. It is made to flow through the rotor and finally discharged through…
Flash welding is a method of welding in which the ends of the workpiece are pressed together during the welding process. Flash welding is a type of resistance welding.In this welding process, a heavy current is passed through the joint.Resistance welding is a type of welding in which resistance is used to develop heat. In…
A vane pump is a positive displacement pump that is used to increase the pressure of the flowing fluid using the vanes which are mounted to a rotor.This pump can be used to flow the fluid from one point to another at high pressure.The vanes in the vane pump can have the variable-length or can be tensioned…
Gear Pump is one type of positive displacement rotary pump. In a gear pump, a fluid moves by enclosing a fixed volume of fluid using the interlocking gears and then transferring it as the gear rotates.This pump delivers a pulse-free flow that is directly proportional to the rotational speed of the gears.The gear pump is mainly used for…
Cone Clutch is a type of frictional clutch. It is used to engage and disengage engine shaft to the transmission box shaft while changing gear ratio.Cone clutch uses two conical surfaces to transmit torque by friction. One surface is called male member and another one is called female member.Cone clutch is easier to engage and…
utocollimator is an optical instrument that is used to measure small angular differences.This device is very sensitive to change in angles and provides a very accurate measurement of angular differences. It is basically a combination of an infinity telescope and a collimator.Autocollimators are mainly used to align optical components and measure optical and mechanical deflections….
Electron Beam Machining (EBM) is a machining process in which material is removed from the workpiece by focusing a beam of high-velocity electrons towards the workpiece.The source of energy in electron beam machining is high velocity electrons. A high voltage DC power supply is used to generate electrons with high energy in this process.It is…
The machining process in which a water jet is used to remove material from the workpiece is called Water jet machining(WJM).In this process, a water jet is used which acts as a tool in the form of water saw.In this process water is greatly accelerated and further concentrated on the target workpiece.This water jet at…
Electrochemical machining is a non-traditional machining process. In the electrochemical machining process, a combination of electrical energy and chemical energy is used to remove material from the workpiece.This process is characterized as a reverse electroplating process but this process removes material instead of depositing it. This process is a non-contact process in which the cavity…
Babcock and Wilcox Boiler is a horizontal, externally fired, water tube, natural circulation boiler.This boiler is named after the persons who discovered it. It was discovered by Herman Babcock and Stephen Wilcox in 1967.This boiler is called natural circulation boiler because the circulation of water in the boiler is maintained by convective current.This boiler is…
