Vacuum pump manufacturers, what is the impact of oil vapor in the process of vacuumizing on the environment? If the environment is not allowed to be polluted, oil-free vacuum pump can be selected, or oil vapor can be discharged outside. Proper combination of vacuum pump. Because the vacuum pump can selectively pump air, sometimes one kind of pump can not meet the requirements of air pumping, and several kinds of pumps need to cooperate and complement each other to meet the requirements of air pumping.

In vacuum pump factory, the sputtering ion pump (or two pole asymmetric cathode sputtering ion pump) has a certain pumping rate for argon. The combination of the two can make the vacuum device obtain a better vacuum degree. In addition, some vacuum pumps can not work under atmospheric pressure and need pre vacuum; And some vacuum pump outlet pressure is lower than the atmospheric pressure, need the front pump, so need to use all the pumps together.

When the working pressure of vacuum equipment is very high, the vacuum pump should be able to discharge all the gas volume produced in the process of vacuum equipment. The vibration produced by the pressure reducing pump does not affect the processing process and environment. If the machining process is not allowed, the non vibration pump or vibration reduction measures should be selected. Understand the composition of the extracted gas, the gas contains no condensable steam, particle dust, corrosivity, etc.

When choosing the vacuum pump, we need to know the composition of the gas and select the corresponding pump for the gas. If there are steam, particles and corrosive gas, it should be considered to install condenser, dust collector and other auxiliary equipment on the pump inlet pipe. Oil pollution requirements of vacuum equipment if the equipment requirements are strict and there is no oil, various types of no oil pump should be selected.

Such as: water ring pump, molecular sieve adsorption pump, sputtering ion pump, cryogenic pump, etc. If the requirements of oil pump are not strict, the oil pump with oil pump can be selected, and some anti oil pollution measures can be added, such as adding cold trap, baffle, oil trap, etc., which can also meet the requirements of vacuum purification.
