Types And Characteristics Of Vacuum Pumps

A vacuum is a gas in which the molecular density of a gas is lower than the standard pressure. The degree of vacuum is a measure of the thinness of a gas, and its most direct physical quantity should be the number of molecules per unit volume. But because of the history, the vacuum is usually expressed as the pressure of the gas, and the lower the pressure of the gas is, the higher the vacuum. There are two types of vacuum pumps.types-and-characteristics-of-vacuum-pumps.

(1) rotary vane vacuum pump:

The type 2X rotary vane vacuum pump is a bipolar structure volume vacuum pump, which is rotated at high speed by the rotor with rotary vane installed eccentrically, so that the volume of the pump chamber changes continuously and the pumping function is completed. The pump is equipped with a pneumatic valve. When a small amount of water vapor is contained in the pumped gas, the valve is opened to inject air into the exhaust chamber of the pump. The type 2X vacuum pump can be used as the main pump separately, or as the front stage pump of the booster pump, diffusion pump and molecular pump.vacuum-pumps-are-used-in-oil-mines
