double stage rotary vane vacuum pump principle

The working performance of two-stage rotary vane vacuum pump is composed of high-pressure stage and low-pressure stage. Its suction port is connected with vacuum container or vacuum equipment. During operation, a large amount of gas in the container will be inhaled and discharged. When the rotary vane vacuum pump obtains the vacuum, the exhaust valve plate of the high pressure stage will be closed, and the gas inhaled by the high pressure stage will be transferred to the second stage, which will be inhaled and discharged by the second stage, so that the vacuum equipment can obtain a certain vacuum.

The technical parameters of the rotary vane vacuum pump are 6 × 10-2Pa. According to the user's use, the vacuum booster pump can be equipped. The rotary vane vacuum pump is used as the front stage pump. As the suction force of the booster pump is strengthened, the front stage pump is continuously removed, which can make your equipment obtain higher vacuum.
