Why does the liquid ring vacuum pump system need to replenish water

Supplementary water for liquid ring vacuum pump system can effectively work on gas and improve efficiency. Supplementary water should enter at the end of liquid work on gas, that is, at the highest point of the compression chamber, so that the unit can get sufficient energy and start again when the next cycle turns.

Advantages of replenishing water in liquid ring vacuum pump system:

1. The loss caused by the exhaust hole of the supplementary liquid ring flowing out with the gas flow;

2. End clearance between sealing pump body and impeller;

3. Compressed heat generated by discharging compressed gas;

4. Cooling and lubricating fillers, packing glands and other spare parts.

For example, the liquid ring vacuum pump system has more supplementary water, and excessive water takes up part of the gas space, which reduces the gas volume and exhaust pressure. Too much water will increase power consumption and reduce efficiency, resulting in noise and vibration. The liquid ring vacuum pump system works unsteadily and periodically sprays a large amount of water from the exhaust holes.

If the liquid ring vacuum pump system has less supplementary water, the compressed heat in the liquid ring vacuum pump system can not be fully discharged, so that the temperature of the water ring and the upper gas rises and the gas volume and vacuum degree decreases; the loss of the water ring can not be supplemented, which not only further reduces the performance, but also stops working because the water ring can not be formed.

In order to improve the working efficiency of the liquid ring vacuum pump system, the water supply should be appropriate, not too much or too little, so as to ensure the good operation of the equipment.
