1. Does the vibration generated by the vacuum pump have any impact on the process and the environment. If the process does not allow, a vibration-free pump should be selected or anti-vibration measures should be taken.
2. Understand the composition of the pumped gas, the gas contains no condensable vapor, whether there is particulate dust, whether it is corrosive, etc. When selecting a vacuum pump, you need to know the gas composition and select the corresponding pump for the pumped gas. If the gas contains vapors, particles, and corrosive gases, you should consider installing auxiliary equipment such as condensers, dust collectors, etc. on the inlet line of the pump.
3. Under its working pressure, the vacuum pump should be able to discharge all the gas generated during the vacuum equipment process.
4. Correctly combine the vacuum pump. Because the vacuum pump has selective pumping, therefore, sometimes the choice of a pump can not meet the pumping requirements, the need for several pumps to combine, complement each other to meet the pumping requirements.
