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…
Atomic Hydrogen Welding ( AHW ) thermo-chemical is a welding process in which welding is done using the arc produced between two tungsten electrodes and hydrogen gas provided by a hydrogen gas cylinder.It is named atomic hydrogen welding because the arc disassociates the hydrogen into atomic form. This process is also known as atomic arc…
A turret lathe is a semi-automatic lathe machine that is used for repetitive production of lathe parts.It is advance from the lathe machine produced earlier as it has a hexagonal turret.Hexagonal turret is an indexable tool holder which can hold six tools at a time. With the help of hexagonal turret, multiple cutting operations can…
Pirani Gauge is a device that is used to measure pressure, especially in vacuum systems. It was invented by a German physicist Marcello Stefano Pirani in the year 1906.It is based on a hot metal wire suspended in a tube and exposed to gas pressure media. This hot metal wire is made up of thin Tungsten, Nickel,…
