rotary vane 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 that move radially under spring
pressure (3) and the inlet and wall plug (4). The wall plug valve is certainly oil-sealed. The inlet valve was created as a
vacuum Cycloidal Reducers safety valve that’s always open during procedure. The working chamber (5) is located
inside the casing. 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 next vane. The enclosed gas can be compressed until the outlet valve opens against
atmospheric pressure. Regarding gas ballast operation, a hole to the exterior is opened, which
empties in to the sealed suction chamber on leading side.
The Rotor moves with the help of a motor mounted on it.
