Generally, Vacuum pump is a device to remove gas molecules from a sealed volume.The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump. There are various types of pumps like multi vane pumps, oil lubricated pumps ,liquid ring vacuum pumps, piston pumps etc…They are classified according to their techniques and applications. These Vacuum pumps are used in mainly industrial and scientific processes including composite plastic moulding processes, production of most type pf electric lamps, vacuum tubes and CRT’S.Especially in the field of transformer maintenance, vacuum pumps plays an vital role, it helps in increasing the life time of transformers. Vacuum may be used to provide assistance to mechanical devices.In hybrid and diesel motor vehicles, a pump is fitted on the engine is used to produce vacuum. This vacuum is used to power the following motor vehicle components : vacuum servo booster for the hydraulic brakes, motor that moves the dampers in the ventilation system, throttle driver in the cruise control servomechanisms and door locks . It is also used in an aircrafts to power the gyroscopes in various flight instruments. TYPES OF VACUUM PUMPS :
The above listed types are the major categories of vacuum pump. In positive displacement pump, a partial vacuum is generated by increasing the volume of a container.It moves the same volume of gas with each cycle, so its pumping speed is constant unless it is overcome by backstreaming. In momentum transfer pump, gas molecules are accelerated from the vacuum side to the exhaust side. Momentum transfer pumping is only possible below pressures of about 0.1 kPa. Regenerative pump works by utilising the vortex behaviour of the fluid and Entrapment pump works by condensing gases to solids by using cold temperatures. There are various leading vacuum pumps manufacturers in India providing innovative vacuum solutions.
