Liquid ring vacuum pump specification

How to choose the type of liquid ring vacuum pump?

1. Try to choose the specification with low speed

Under the premise of achieving the same amount of air, should try to choose the pump with lower speed, large pump consumption than power, that is, higher efficiency

In addition, the larger size of the liquid ring vacuum pump due to the long blade (that is, the flow channel is long), the fluid curvature is small, the flow line is approximate to a straight line, the fluid flow is close to the slow change of the flow, the fluid flow generated by the secondary eddies and boundary layer caused by the energy loss is also small

2. Consider the influence of water temperature

The temperature of most supplementary water is between 25 ° c and 35 ° c, so pump selection should be more than the amount of gas on the technical document appropriate increase

3. Influence of inspiratory resistance

In the layout of the pipeline, the larger suction pipe should be used to reduce the resistance loss, and try to reduce the right Angle elbow, in order to achieve the purpose of improving the suction efficiency

4. Selection of exhaust with micro positive pressure

(1) the influence of rising exhaust pressure and increasing backflow in the pump chamber on the volume of air extraction should be considered

As the exhaust pressure rises, the pump shaft power increases, with the power of the driving machine should also increase, in the selection should refer to the test performance curve and the corresponding technical data, in order to fully meet the requirements

Liquid ring vacuum pump of model specification

With the rapid development of vacuum technology, in order to adapt to the industrial, chemical and other fields of standards, vacuum pump models are also different. Industrial area, usually used 2 be1 liquid ring vacuum pump and 2 bv liquid ring vacuum pump. The next two types of vacuum pump models and the parameters of each model standard. Of course, it can also be customized.
