The centrifugal pump only cuts the impeller, does not change the electrical machinery, can achieve the energy conservation goal?
Actual application of the pump, flow, lift head than the actual needs of large, with throttle valve to reduce flow, at this time cutting impeller can be energy-saving, do not change the motor.
Can not ah, can only reduce the motor load, for energy saving, the effect is not large
As long as the motor is not particularly large, such as power than the actual power more than doubled, the efficiency changes little, do not change.If not the existing pump, cutting impeller can not save energy, most of the efficiency to drop a little
