What are the parts of a Rotary Vane Vacuum Pump?
The inlet valve, if available, is designed as a vacuum safety valve that is always open during operation. As the rotor turns, gas flows into the enlarging suction chamber until the second vane seals it off. The enclosed gas is compressed until the outlet valve opens against atmospheric pressure. The outlet valve is oil-sealed. When the valve is open, a small amount of oil enters the suction chamber, lubricating it and sealing the vanes against the housing (stator).

Working Principle
The Working Principle of Rotary Vane Vacuum Pump
The rotor and the vanes divide the working chamber into two separate spaces with variable volumes. As the rotor turns it, the trapped gas flows into a suction chamber until the second vane seals it off. Then the enclosed gas is compressed until the outlet valve opens aligned with atmospheric pressure. In a gas ballast operation, a hole to the outside is then extended to empty into a sealed suction chamber on the front side of the pump.

FAQ
Knowledge About Rotary Vane Vacuum Pump
Differences Between Single Stage And Double Rotary Vane Vacuum Pumps?
The high rate of oil flow in the atmospheric level of hydraulic noise in the high vacuum stage does not exist. The lThe low oil flow rate makes the double rotary vane vacuum pump suitable for working under intense pressure and not for continuous work under high pressure. Even in the absence of town gas, the double rotary vane vacuum pump noise level is generally lower than the single-stage rotary vane vacuum pump.
