Working principle of oil sealed vacuum pump

Working principle of oil sealed vacuum pump:

By changing the mechanical vacuum pump exhaust, maintenance and Realization of collective vacuum seal oil seal, pump cavity volume of moving parts. They work in the whole plant mechanical pump cavity volume, reduce the increase in emissions. When the pump chamber becomes the capacity of the working chamber, the pump inlet is connected to the air chamber and the largest until the re suction volume is far away from the pump suction chamber for the longest time. When the volume is reduced until the atmospheric pressure of the gas is higher than that of the compressed gas discharge valve, the discharge pressure of the gas is lower.


For oil seal pump fluid:

Large mechanical vacuum pumps, even the best design, and the relative motion between components are currently used, even with high precision. Vacuum pump limit, which is difficult to prevent low true air "break through" the end of the return inlet. In addition, due to the design, manufacture and inevitable harm of the pump, and reduce the assembly clearance limit vacuum. The components of relative movement between oil sealed vacuum pumps and the sealing of exhaust valves; the opportunity of harmful space filling to make it a "breakthrough" of high pressure gas is much less, more, better sealing performance, it can pump higher vacuum.
