rotary vane pump

A rotary vane vacuum pump can be 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
push (3) and the inlet and outlet (4). The wall plug valve is certainly oil-sealed. The inlet valve was created as a
vacuum safety valve that’s always open during procedure. The working chamber (5) is situated
inside the casing. Rotor and vanes divide the functioning 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 next vane. The enclosed gas is certainly compressed before 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 leading side.
The Rotor moves with the aid of a motor attached to it.
