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
drive (3) and the inlet and store (4). The store valve can be oil-sealed. The inlet valve was created as a
vacuum safety valve that’s always open during operation. The working chamber (5) is situated
inside the housing. Rotor and vanes divide the working chamber into two separate spaces having
adjustable 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 is definitely compressed before outlet valve opens against
atmospheric Planetary Gear box pressure. Regarding gas ballast procedure, a hole to the exterior 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.
