Water Ring Vacuum Pump Unit WorkTo a large extent, the role of water ring vacuum pump unit is to create a preparatory vacuum needed by Roots pump. In general, for single stage vacuum pump unit, we should pay attention to the fact that the ultimate vacuum of itself is not high, and we In fact, we should pay attention to some things.At present, the pre-vacuum required by our roots pump is actually relatively high. In view of this, we will not use the single-stage water ring vacuum pump unit directly as a front pump on the roots pump. Next, we should pay attention to the extreme pressure. The lower two-stage water ring pump is used as the front-stage pump, which can actually reduce a limit pressure of the unit itself.In fact, the limit pressure of a vacuum pump unit and a water ring pump is 400 Pa. In this respect, to a large extent, it can directly meet the vacuum demand in general. However, in terms of its scope of use, we should pay attention to its own suffering. To a certain limit.When we directly connect two Roots pumps in series and then combine them with vacuum pumps, to a certain extent, it can greatly improve the limit pressure of the unit itself (up to 25 Pa). It is precisely because of this, we should pay attention to, in fact, in this type, the more common is that two Roots pumps in series and then use two-stage pumps directly as the components of the former pump unit.However, as far as the application of vacuum pump unit is concerned, when we need a higher limit pressure, that is to say, we should pay attention to the combination of three Roots pumps and vacuum pump unit. In terms of its limit pressure, to a certain extent, it is actually direct. It reaches 1 Pa.
