Today, I’m here to briefly introduce the relevant information about the air pumping requirements of the liquid ring vacuum pump. I hope it can help you to use it in future purchase. Please follow the editor to learn about the following content.
Properly assemble the liquid ring vacuum pump. Because of the selective pumping of vacuum pump, sometimes selecting one vacuum pump can not meet the pumping requirements. Several vacuum pumps need to be combined to supplement each other to meet the vacuum pumping requirements.
If the vacuum pump has a high pumping speed for hydrogen, but it can not extract helium, and the tripolar sputtering ion vacuum pump (or the two pole asymmetric cathode sputtering ion vacuum pump) has a certain pumping speed for argon, and the combination of the two will make the vacuum device get a good vacuum.
In addition, some vacuum pumps can’t work under atmospheric pressure and need pre vacuum; some vacuum pumps need pre stage vacuum pumps because the outlet pressure is lower than atmospheric pressure, so they need to be combined for use.
