Rotary pump

Rotary pump (dry) - is a rotary vane vacuum pump consisting of a body (cast iron, steel, composite), with two sides closed front and back covers. Inside housing is located eccentric rotor, which rotates on two ball bearings located in the lid of the housing.

The rotor has several grooves ( 4 or more) along the entire rotor, in which freely moving textolite or graphite vanes. During rotation of the rotor blades under the action of centrifugal force pressed against the inner surface of the housing.

Due to the eccentric located in the rotor housing between the vanes, the rotor and the housing are formed camera, different in scope. When the rotor space between blades-casing and a rotor having a zone of vacuum and compression zones. Compressed the air expands and is expelled through the system piping and muffler in atmosphere. The vacuum region through a system of pipes connected to vacuumized space and pumping gas.

Lubrication of rotary pump forced. Due to the underpressure (vacuum) is created in the suction the connection of the pump and the bearing cavities, compressor oil through tubes through grease enters the pump, where it is atomized and lubricates the rubbing surface details: cervical shafts, bearings, blades.

In depending on the model and materials used rotary vacuum pumps provide a fairly wide range of performance and level of vacuum.
