What are the sealing requirements of vacuum pump

Vacuum pump is a common vacuum equipment, so what are the sealing requirements of vacuum pump?

Under its working pressure, the vacuum pump should be able to discharge all the gas produced in the process of vacuum equipment. Combine the vacuum pump correctly. Because of the selective pumping of vacuum pump, sometimes selecting one pump can not meet the pumping requirements. Several pumps need to be combined to supplement each other to meet the pumping requirements. For example, the titanium sublimation pump has a very high pumping speed for hydrogen, but it can't pump helium, while the three pole sputtering ion pump (or the two pole asymmetrical cathode sputtering ion pump) has a certain pumping speed for argon, and the combination of the two will make the vacuum device get a better vacuum degree.

Vacuum pump can not work under atmospheric pressure, need pre vacuum, some vacuum pump outlet pressure is lower than atmospheric pressure, need pre pump, so we need to combine the pump. Requirements of vacuum equipment for oil pollution. If the equipment is strictly oil-free, various oil pumps should be selected, such as: water ring pump, molecular sieve adsorption pump, sputtering ion pump, low temperature pump, etc. If the requirements are not strict, oil pump can be selected, and some anti oil pollution measures, such as cold trap, baffle, oil trap, etc., can also meet the requirements of clean vacuum.

The vacuum pump shall be installed in a solid place on the ground, and there shall be sufficient space around it for inspection, maintenance and repair. The foundation level shall be kept under the vacuum pump base. It is recommended to pad damping rubber or install it with bolts at the four corners of the base to ensure the smooth operation and small vibration of the vacuum pump.

The connecting pipeline between vacuum pump and system shall be sealed reliably. For small vacuum pump, metal pipeline connection gasket can be used, and oil-resistant rubber can be used. For small vacuum pump, vacuum rubber pipe connection can be used. The pipe diameter shall not be less than the suction diameter of vacuum pump, and the pipeline shall be short with few elbows.
