The liquid ring vacuum pump is an important equipment in industrial production. Its selection is directly related to the efficiency of operation. Therefore, it is necessary to select the pump correctly. So, how do we choose the liquid ring vacuum pump?
1. Type determination: The type of liquid ring vacuum pump is mainly determined by the gas volume, vacuum degree or exhaust pressure required for work. When working, we should pay attention to the following two aspects:
1. Operate in the high efficiency area as far as possible, that is, in the critical vacuum or critical exhaust pressure area.
2. Operating near the maximum vacuum or exhaust pressure should be avoided. Operating in this area is not only very inefficient, but also very unstable and prone to vibration and noise. For vacuum pumps with high vacuum, cavitation often occurs when they operate in this area. The obvious sign of this phenomenon is that there is noise and vibration in the pump.
2. Choose vacuum pump according to the volume of air required by the system: After the type of pump is initially selected, the type of vacuum pump should be selected according to the volume of air required by the system.
When choosing and purchasing, we can determine the type and type of liquid ring vacuum pump according to the required gas volume, vacuum degree or exhaust pressure, so as to ensure that the selected pump can meet the actual needs and run efficiently in operation.
