Applications :-
Single stage pumps work well for rough vacuum levels and are less expensive than similar two-stage versions.
Rotary Vane Vacuum Pump
A rotary vane vacuum pump is an oil-sealed rotary displacement pump. The pumping system consists of a housing
(1) an eccentrically installed rotor
(2) vanes
(3) that move radially under centrifugal and resilient forces and the inlet and outlet
(4) The inlet valve, if available, is designed as a vacuum safety valve that is always open during operation.
(5) The working chamber is located inside the housing and is restricted by the stator, rotor and the vanes.
The eccentrically installed rotor and vanes divide the working chamber into two separate compartments with variable volumes. As the rotor turns, gas flows into the enlarging suction chamber until it is sealed off by the second vane. The enclosed gas is then 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 and not only lubricates it but also seals the vanes against the housing (stator).
