How to know more exactly the operation status of a water ring vacuum pump equipment? In fact, it can be regarded as a physical problem. First, we should see which aspects of the situation to be solved, and then we can calculate the relevant data into the formula. The specific speed of water ring vacuum pump can also be calculated as follows:

As the basis of pump standardization, specific speed can reflect the general parameters of water pump. Under the highest efficiency, the size of the pump is reduced (or expanded) according to a certain proportion, so that the effective power Pu = 0.7355kw, the lift HM = 1m, the flow QM = 0.075m3/s. At this time, the speed of the model pump is called the specific speed of the actual pump which is similar to it.

Although the specific speed is obtained according to the similar relationship, it contains many actual parameters. Therefore, it reflects the main performance of the actual water ring vacuum pump; when the speed of the water ring vacuum pump is fixed, the greater the specific speed, the greater the pump flow and the lower the lift; on the contrary, the smaller the specific speed, the smaller the pump flow and the higher the head.

With the formula, as long as we measure the relevant data, we can accurately know the specific speed of the water ring vacuum pump, so that the actual and theoretical combination, so that we can be very good use.
