Vacuum pump

XD single-stage multi rotary vane series vacuum pump adopts foreign advanced technology, high-tech materials and advanced technology. The utility model has the advantages of compact structure, beautiful appearance, high vacuum degree, wide application range, long service life, convenient maintenance, vacuum pumping and air compression. It is mainly used for super large, medium and small fecal suction and sewage suction vehicles, industrial and mining enterprises and schools.

When the eccentric rotor rotates, the rotary vane slides against the inner wall of the pump body under the action of centrifugal force, the volume of the suction chamber gradually increases, and the pumped gas is sucked into it until the rotary vane turns to the end of suction, and the inhaled gas is isolated.

The rotor continues to rotate, the isolated gas is gradually compressed, and the pressure increases. When the pressure exceeds the pressure at the exhaust port, the gas is discharged from the pump. In this way, the air in the container is pumped to form a vacuum.
