direct-connected rotary vane vacuum pump

The eccentrically mounted rotor in the pump is tangent to the fixed surface of the stator, and two (or more) rotary vane slide in the rotor groove (usually radial) and are in contact with the inner wall of the stator, dividing the pump chamber into several variable-volume rotary variable-volume vacuum pumps.Usually, the gap between the rotary vane and the pump chamber is sealed with oil, so rotary vane vacuum pumps are generally oil-sealed mechanical vacuum pumps.

The 2XZ rotary vane vacuum pump is the basic equipment used to remove gas from sealed containers.It can be used alone or as a pre-stage pump for booster pumps, diffusion pumps, molecular pumps, maintenance pumps, and titanium pumps; this series of pumps has the advantages of low sound, no oil return when the pump is stopped, and easy to start. The pump is equipped with an air ballast valve, which can remove a small amount of condensable steam.This vacuum pump cannot remove excessive oxygen content, corrosive, explosive or toxic (except for 2XZFL explosion-proof rotary vane vacuum pumps), and gases containing fine particles of dust, nor can it be used as compression pumps or air delivery pumps.

The XD series rotary vane vacuum pump is a type of vacuum pump with a relatively complete design that can operate at any inlet pressure.Therefore, it has a wider range of applications than conventional rotary vane vacuum pumps. Currently, this type of pumps is widely used for vacuum packaging of various types of food products, forming vacuum blisters in the rubber and plastic industries, transporting paper in the printing industry, vacuum impregnation and sealing of food products. various castings, vacuum fixtures, vacuum drying, vacuum filtration, vacuum dynamic testing and vacuum suction in hospital operating rooms. Vacuum treatment is within the vacuum range that this pump can provide.
