Each product in use after a period of time, there will be a failure, but for the use of a period of time there may be a decline in operating efficiency, resulting in lower efficiency of sewage pump operation, to understand.
1, due to the erosion of the water flow, the sewage pump inner wall and the impeller over the water surface becomes rough, the sewage pipe flow resistance coefficient increases, coupled with the water flow in the pump is very large, head loss increases. Reduced hydraulic efficiency.
2, due to the sewage pump before the addition of drugs or water quality and other reasons, so that the pump casing serious fouling or corrosion. Pump casing serious dirt can make the pump casing wall thickness increases about 2ram, and the sewage pump wall formation scale tumor, so that the pump volume reduced, pumping reduced, and the flow channel rough, head loss increased. Passenger efficiency and hydraulic efficiency are reduced.
3, due to the processing process caused by the diaphragm diaphragm pump pump defects, cavitation, erosion, corrosion and chemical erosion and other causes of pump flow channel generated voids or cracks, water flow caused by the vortex caused by energy loss. Reduced hydraulic efficiency.
4, impeller surface cavitation.
5, volume loss and mechanical loss. As the pump is used for a long time, mechanical wear is lost and the resistance increases, resulting in reduced volumetric efficiency and mechanical efficiency.
Sewage pump should be observed in the running time, so that early detection of these failures, timely processing. Early processing will not cause too much loss. For more information on the prices of wholesale sewage pump manufacturers, please keep an eye on our website
