A rotary vane vacuum pump is an oil-sealed rotary displacement pump. The pumping system
consists of a casing (1), an Vacuum Pump eccentrically installed rotor (2), vanes that move radially under spring
power (3) and the inlet and store (4). The store valve is certainly oil-sealed. The inlet valve was created as a
vacuum safety valve that is always open during procedure. The working chamber (5) is located
inside the housing. Rotor and vanes divide the working chamber into two separate spaces having
variable 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 is usually compressed before outlet valve opens against
atmospheric pressure. In the case of gas ballast operation, a hole to the outside is opened, which
empties in to the sealed suction chamber on the front side.
The Rotor moves by using a motor attached to it.
