Water pump failure analysis and treatment
Different types of pumps, the failure of the form of expression is not the same, but in general, there are 5 common characteristics.
(1) insufficient flow;
Causes: lack of impact of water flow is the water pipe leakage, valve leakage; water plugging; water depth at the end of valve insufficiency; the pump speed is too low; the impeller sealing ring or excessive wear; high water exceed the standard.
Treatment methods: check valve and water pipe, blocked the leak source; clean water inlet sludge or blockage; water depth at the end of valve must be greater than 1.5 times the diameter of the water inlet pipe, increase the water depth at the end of valve; check the power supply voltage, improve the pump speed, to replace the sealing ring or impeller; the installation of pumps to reduce or replace the high lift pump.
(2) power consumption is too large
Cause: pump speed is too high; pump shaft bending or pump shaft and motor shaft misalignment or not parallel; selection of the pump head is not suitable; pump suction or sediment blockage; motor ball bearing damage.
Treatment methods: check the circuit voltage, reduce the pump speed; the relative position correction of pump shaft or adjust the pump and motor; appropriate lift pump; clean sediment or blockage; the replacement of ball bearing motor.
(3) violent vibration or noise of pump body;
Causes: pump installation is not fixed or water pump installation is too high; motor ball bearing damage; water pump spindle bending or with the motor spindle is not concentric, not parallel.
Handling method: install the stable water pump or reduce the installation height of the water pump; replace the motor ball bearing; correct the bent main shaft of the pump or adjust the relative position of the pump and the motor.
(4) overheating of drive shaft or motor bearing;
Causes: lack of lubrication or bearing breakage.
How to do it: add lubricating oil or replace the bearings.
(5) the water pump does not produce water
Causes: pump body and suction pipe are not filled with water; the water level is lower than the water pump filter pipe; water pipe rupture.
Processing method: remove the end of valve failure, filled with water; reduce water pump installation, and make the water pipes under the water level in the dynamic, or moving water pipes or filters and then pumping; repair or replacement of water pipes.
