How to improve the pump efficiency Improve the pipeline system, reduce resistance.Line length should as far as possible, shorten and keep straight, lower velocity in order to reduce frictional head loss;Reducing valve, bottom valve, elbow, the number of orifice plate etc, in order to reduce the local head loss.Reduce the amount of rich water pump outlet pressure, appropriately meet the requirements of pipeline system for the pressure. Pump is the most widely used general machinery and power consumption, energy consumption and thus improve the efficiency of the pump itself and the pump efficien […]
