rotary vane pump

A rotary vane vacuum pump is 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
Taper Pulleys pressure (3) and the inlet and store (4). The wall plug valve is usually oil-sealed. The inlet valve was created as a
vacuum safety valve that is always open during procedure. The working chamber (5) is situated
inside the housing. Rotor and vanes divide the operating chamber into two separate spaces having
adjustable volumes. As the rotor turns, gas flows in to the enlarging suction chamber until it is sealed
off by the second 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 into the sealed suction chamber on leading side.
The Rotor moves with the help of a motor mounted on it.
