Presumably you have a certain understanding of all aspects of the liquid ring vacuum pump, and there are some more in-depth issues that need to be discussed with you. Today's content is about the pumping requirements of the liquid ring vacuum pump, I hope you can take a serious look at it.
Because vacuum pumps have selective pumping, sometimes one pump can not meet the requirements of pumping. It needs several pumps to be combined to complement each other in order to meet the requirements of pumping. For example, the titanium sublimation pump has a high pumping speed for hydrogen, but it can not pump helium, while the tripolar sputtering ion pump (or the bipolar asymmetric cathode sputtering ion pump) has a certain pumping speed for argon. If the two pumps are combined, the vacuum device will get a better vacuum degree. In addition, some vacuum pumps can not work at atmospheric pressure, need pre-vacuum; some vacuum pumps outlet pressure is lower than atmospheric pressure, need the front pump, so they need to be combined to use.
Although the liquid ring vacuum pump can be selectively pumped, it must meet certain requirements when pumping. Therefore, we need our staff to pay special attention to this work.
