How To Reduce Water Pump Energy Consumption in Spring

Feb 22, 2025

Spring is coming, and the use of water pumps is about to enter its peak period. How should water pumps be used and what issues should be paid attention to in order to reduce energy consumption and save costs?

1, The surface of the water pump and the inner surface of the pressure chamber (also known as the volute) are corroded and uneven.

Surface rust and unevenness can reduce pump water flow by 7% -8%; During maintenance, simply use a steel brush and iron sandpaper or grinding wheel to smooth it out, which can reduce fuel consumption or electricity consumption by 9% -14% during operation

2, The gap between the sealing rings increases

According to the test, when the clearance in the radial direction of the impeller increases by 4 millimeters, the pump water volume will decrease by 10%; During maintenance, simply use organic adhesive and asbestos thread to restore the factory specified gap, which can reduce the fuel consumption or electricity consumption of the pump by 10% -12% during operation

3, The axis of the pressurized water chamber and impeller does not coincide

When the axis of the pressure chamber deviates from the impeller by 2 millimeters or the deviation angle is greater than 2 degrees, the pump water volume will decrease by 5% -6%; During maintenance, only careful measurement is needed to accurately locate the position where the axis coincides and install it securely, which can reduce the oil or power consumption of the pump by 6% -7% during operation.
