In order to make you better choose and use the vacuum pump, we have summarized the following precautions so that you can choose the right product. According to the actual use, we should pay attention to these: 1. Whether the vibration produced by the small vacuum pump has an impact on the process and environment. If the process is not supported, the pump without vibration shall be selected or a series of anti vibration measures shall be taken. 2. Understand the composition of the extracted gas, whether there are particles, dust and corrosivity in the gas. 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 vapor, particles and corrosive gas, it is necessary to consider installing auxiliary equipment on the air inlet pipeline of the pump. 3. Under its working pressure, small vacuum pump can discharge all the gas produced in the process of vacuum equipment. 4. Combine the vacuum pump correctly. Sometimes the selection of one pump can not meet the pumping requirements. Because the vacuum pump has selective pumping, several pump combinations are needed to supplement each other to meet the pumping requirements. If the titanium sublimation pump has a high pumping speed for hydrogen, but cannot pump helium, and the three pole sputtering ion pump (or the two pole asymmetric cathode sputtering ion pump) has a certain pumping speed for argon, the vacuum device will obtain the corresponding vacuum degree. 5. Requirements for oil pollution of small vacuum equipment. If the equipment clearly requires no oil, various non oil pumps should be selected. If the requirements are not strict, oil pumps can be selected and some oil pollution prevention measures can be taken. 6. Correctly select the working point of small vacuum pump. Each pump has a certain working pressure range. Therefore, the working point of the pump should be selected within this range rather than long-term operation under 25 ~ 30mmhg. 7. How does the oil vapor discharged by the small vacuum pump affect the environment. If the environment is not allowed to be polluted, you can choose an oil-free small vacuum pump, or discharge the oil vapor outdoors. 8. The working pressure of small vacuum pump should meet the requirements of extreme vacuum and working pressure of vacuum equipment. For example, a vacuum drying process requires a working vacuum of 10mmhg, and the limit vacuum of the selected vacuum pump should be at least 2mmhg, preferably 1mmhg. Generally, the extreme vacuum degree of the pump is half to one order of magnitude higher than the working vacuum degree of the vacuum equipment.
