How Compression Works in Vacuum Pumps
How Compression Works in Vacuum Pumps
January 19, 2017

 

A compressor vacuum pump operates on the principle of air displacement. This creates low pressure zone and a pressure difference between the ends of the source and destination of the fluid. The pump has rotors that rotate in opposite directions within the pumping chamber. As the claws of the rotor move closer to the inlet port, air is sucked into the rear end of the compression chamber. With the continuous rotation of the rotors, the volume of the air trapped between the rotors and the walls of the chamber is compressed leading to an increase in the pressure.

 

The conventional design of the compressor vacuum pump deploys an oil-free technology where only the rotor gearbox is ventrally placed in the rotor chamber. This makes the compression vacuum pumps useful as either pumps or blowers that put compress air into low pressure and high volume and vice versa. A repeat of the high pressure and low pressure zones between the rotor chamber and the outside environment leads to the creation of a vacuum in the chamber relative to the external environment whose pressure is higher. This makes air from the external high pressure zone dash into the vacuum within the pump where it is compressed by the rotating rotor arms. The process is repeated as the pumping and compression continues over time.
