Analysis on the Causes of the Decrease of the Horizontal Water Pump
1. Adding medicines or water quality before the pump causes serious fouling or corrosion in the pump casing. Severe fouling in the pump casing can increase the wall thickness of the pump casing by about 2 ram, and the inner wall of the horizontal water pump will form scale tumors, which will reduce the volume of the pump body, reduce the pumping capacity, and rough the flow path, increase the head loss, and increase the efficiency The hydraulic efficiency is reduced.
2. With the scouring of the water flow, the inner wall of the horizontal water pump flow channel and the impeller surface become rough and uneven, the friction coefficient of the flow channel in the horizontal water pump increases, and the flow rate of the water in the pump is large, and the head loss increases. The hydraulic efficiency is reduced.
3. Cavitation on the surface of the impeller. Because the negative pressure is generated when the back surface of the blade is running, when the pressure is Pk, the vapor cavity and honeycomb surface are generated, and the pump blade is cavitation under the action of electrochemical corrosion.
4. Casting defects, cavitation, abrasion, corrosion and chemical erosion caused by the horizontal water pump processing technology cause cavities or cracks in the pump flow channel, and vortexes are generated when water flows, which causes energy loss and reduces hydraulic efficiency.
5. Volume loss and mechanical loss. As the pump is used for a long time, the leakage and resistance increase due to mechanical wear, which reduces the volumetric efficiency and mechanical efficiency.
The above reasons make the performance of the horizontal water pump worse. The operating efficiency is reduced by 2 to 5%, and the efficiency of the horizontal pump can be reduced by more than 10% in serious cases.
