rotary vane pump

A rotary vane vacuum pump is an oil-sealed rotary displacement pump. The pumping system
consists of a Screw Air Compressors housing (1), an eccentrically installed rotor (2), vanes that move radially under spring
force (3) and the inlet and wall plug (4). The wall plug valve is certainly oil-sealed. The inlet valve is designed as a
vacuum safety valve that’s always open during procedure. The working chamber (5) is located
inside the housing. Rotor and vanes divide the working chamber into two individual spaces having
variable volumes. As the rotor turns, gas flows in to the enlarging suction chamber until it really is sealed
off by the second vane. The enclosed gas is certainly compressed until the outlet valve opens against
atmospheric pressure. In the case of gas ballast procedure, a hole to the outside is opened, which
empties into the sealed suction chamber on the front side.
The Rotor moves by making use of a motor attached to it.
