A rotary vane vacuum pump can be an oil-sealed rotary displacement pump. The pumping system
consists of a casing (1), an eccentrically installed rotor (2), vanes that move radially under spring
force (3) and the inlet and Reciprocating Vacuum Pump outlet (4). The store valve is certainly oil-sealed. The inlet valve is designed as a
vacuum safety valve that is always open during procedure. The working chamber (5) is situated
inside the casing. Rotor and vanes divide the operating chamber into two individual spaces having
variable volumes. As the rotor turns, gas flows into the enlarging suction chamber until it really is sealed
off by the second vane. The enclosed gas is definitely compressed before outlet valve opens against
atmospheric pressure. In the case of gas ballast procedure, a hole to the exterior is opened, which
empties in to the sealed suction chamber on the front side.
The Rotor moves with the aid of a motor attached to it.
