What are the principles of rotary vane vacuum pump

The rotary vane vacuum pump is a series connection of the main pump and the former stage pump. The rotary vane vacuum pump selects the rotary vane pump as the front stage pump, so it overcomes the defect of low pumping rate of rotary vane vacuum pump under certain pressure when it is in use, and retains the advantages of roots pump, such as agile operation and relatively large pumping rate.

Because of its compact structure and small floor area, rotary vane vacuum pump can replace multiple mechanical vacuum pumps. Therefore, rotary vane vacuum pump units are widely used in vacuum training, power capacitor, transformer vacuum heat treatment, vacuum coating equipment pre pumping, electric vacuum semiconductors and other occupations, which will not react with pump oil and contain no particulate dust.

Next, I'd like to introduce you to the following introduction, and maybe you can make a profit from it. How does the rotary vane vacuum pump work? Let's learn about it. When the rotary vane vacuum pump in the laboratory is lower than the full steam pressure under the pump temperature, it can be filled with gas and discharged from the pump at any time to avoid condensation in the pump oil. In addition, when the closed pump mouth is working.

The condensate of condensable gas that has been mixed into the oil may be dissolved in the oil in the gas phase, which will overflow from the pump cavity. At this time, if the mission of opening the gas town, a certain amount of condensable substances can be pumped out, and then play a certain pollution effect, extending the operation period of the pump oil.
