How can we choose a vacuum pump unit that meets our requirements
In order to select the time of vacuum pump unit, in terms of its operating pressure, in fact, it is necessary to directly satisfy the requirements of a limit vacuum of vacuum equipment and its operating pressure. In this respect, a vacuum drying process requires a working vacuum of 10 mmHg, and then a limit vacuum of 2 mmHg for the vacuum pump unit to be selected.
As for the vacuum pump unit, we should pay attention to it. As far as it is concerned, it is better to reach 1mmHg. Generally speaking, regarding the selection of the limit vacuum degree of pumps, it is actually to be directly higher than the vacuum degree of vacuum equipment operation half or to an order of magnitude.

Moreover, we should pay attention to this aspect. In fact, we should correctly select a working point of the vacuum pump unit. For each pump, in fact, there will be a certain scale of operating pressure. If we talk about the operating pressure of 2BV series water ring vacuum pump, its scale will be in fact 760 mmHg ~ 25 mmHg (absolute pressure), just in such a wide range of pressure.
In terms of pumping speed of our vacuum pump unit, it will actually change with its pressure (in terms of its specific change, actually referring to the function curve of the pump directly). In this case, in terms of its stable operating pressure scale, it will actually be in the range of 760-60 mmHg. It is also the odor, as far as the operation point of the pump is concerned, it should be selected within this scale to be able to.
