What is the reason that the water supply of pump is getting smaller?
1, the water pump screen plug, should remove the filter screen sundries.2, the use of lift is too high. Over the pump range, the pump should be adjusted to use height or replace the pump head.3, pump impeller plug or wear, should remove the impeller sundry. Replace the impeller if worn.4, pump outlet pipe blocked by debris, should remove the debris in the pipe outlet.5, diameter and pump does not match, replace the outlet pipe.6, the pump cover gap is too large, increased pump volume loss, should adjust the gap.7, pump body and pump cover leakage, should tighten the pump cover screw, make the pump body and pump cover close coordination.8, the pump speed is low, the use of voltage is too low. Should adjust the voltage to the rated value, replace the thicker cable or avoid peak use.9, water pump diving depth is too shallow, there is air intake, should adjust the diving depth. Pump running depth is not less than 0.5 meters.Yi Mai water pump to help you answer, I hope to help you
1., first look at the external situation, to see whether the water pump is running, the water level is not normal, the water inlet has nothing blocked.2., exclude the external situation, or small water, the pump itself may leak, it will also make water smaller
What kind of pump is it, home pump or factory pump? Single stage impeller or multistage impeller? Vertical or horizontal? Is it single suction or double suction? Different structure of the day pump has different causes of failure. But in general, there are several aspects: 1., the water inlet is small, the inlet pipe is blocked; 2., the blade is worn or broken; 3., the motor speed drops; 4., sealing serious leakage; 5., cavitation phenomenon.
