rotary vane pump

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 wall plug (4). The store valve can be oil-sealed. The inlet valve was created as a
vacuum safety valve that’s always open during procedure. The working chamber (5) is located
inside the gear motor for greenhouse housing. Rotor and vanes divide the operating chamber into two separate spaces having
variable volumes. As the rotor turns, gas flows into the enlarging suction chamber until it really is sealed
off by the next vane. The enclosed gas can be compressed before outlet valve opens against
atmospheric pressure. In the case of gas ballast operation, a hole to the outside is opened, which
empties in to the sealed suction chamber on the front side.
The Rotor moves with the aid of a motor mounted on it.
