As we all know, double suction pump has high lift, flow and other characteristics, widely used in engineering. Of course, understanding the factors that affect the efficiency of the double suction pump, the purchase of your double suction pump products are also very helpful. The following is the double suction pump efficiency decline of the five major reasons for your reference. Five reasons for the double suction pump efficiency decline Double suction pump efficiency reasons 1, due to the erosion of water flow, the inner wall of the pump runner and impeller over the water surface becomes rough, the water pump friction coefficient increases, plus water The flow rate in the pump is very high, head loss increases. Hydraulic efficiency is reduced. 2, due to dosing drugs or water quality before the pump and other reasons, so that the pump casing serious scaling or corrosion. Serious pump casing can make the pump shell wall thickness increased 2ram or so, and the formation of dirt on the pump wall, so that the pump volume is reduced, reducing the amount of pumping, and the runner rough, increased head loss. Passenger plot efficiency and hydraulic efficiency are reduced. 3, due to casting process caused by pump defects, cavitation, erosion, corrosion and chemical etching and other causes of hollow or cracks in the pump flow path, resulting in vortex water flow caused by energy loss. Hydraulic efficiency is reduced. 4, the cavitation of the impeller surface. Negative pressure is generated when the blade is running on the water surface, with pressure Pk 5, volume loss and mechanical loss. Due to the long pump life, loss of mechanical wear and increased resistance, the volumetric efficiency and mechanical efficiency. The above reasons, the performance of the pump worse. Operating efficiency decreased by 2 ~ 5%, serious pump efficiency can be reduced by 10% or more. These are the reasons for the decline in the efficiency of double suction pumps introduced, I hope you buy double suction pump products help.
