Rotary vacuum pump is oil seal rotary piston pump. The outlet valve is oil-sealed. The intake valve is designed as a vacuum safety valve, which is always open during operation. It can be used alone or as a pre-pump for booster pump, diffusion pump, molecular pump and titanium pump. It is also used in electronic equipment production, vacuum drying, filtration, welding, metal smelting, etc.
2XZ-2 rotary vane vacuum pump is mainly composed of pump body, rotor, rotary vane, end cover, spring and so on. The rotor is installed in the cavity of the rotary vane pump. The outer surface of the rotor is tangent to the inner surface of the pump. Two rotating blades with springs are installed in the rotor groove. When it rotates, centrifugal force and spring tension keep the top of the rotating blade in contact with the pump chamber wall, and the rotating rotor drives the rotating blade to slide along the inner wall of the pump chamber.
