Description

Two Stage Direct Drive Rotary Vane Vacuum Air Pump, Air Pumping Speed 4L/S

(Type: 2XZ-4)

1, Application:

  Rotary Vane vacuum pump, with two-stage pumps able to reach pressures well below 10-6 bar. These vacuum pumps are found in numerous applications, such as providing braking assistance in large trucks and diesel powered passenger cars (whose engines do not generate intake vacuum) through a braking booster, in most light aircraft to drive gyroscopic flight instruments, in evacuating refrigerant lines during installation of air conditioners, in laboratory freeze dryers, and vacuum experiments in physics. In the vane pump the pumped gas and the oil are mixed within the pump, and so they must be separated externally. Therefore the inlet and the outlet have a large chamber–maybe with swirl–where the oil drops fall out of the gas. Sometimes the inlet has a venetian blind cooled by the room air (the pump is usually 40 K hotter) to condense cracked pumping oil and water, and let it drop back into the inlet. When these pumps are used in high vacuum systems (where the inflow of gas into the pump becomes very low), a significant concern is contamination of the entire system by molecular oil backstreaming.
