Analysis and treatment of common faults of water pump
Different types of pumps, the performance of the form of failure is not the same, but summed up.
1. Inadequate 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. Increasing the water depth at the end of valve; check the power supply voltage, improve the pump speed, sealing ring or impeller repair or replacement; reduce water pump installation, or replacement of 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.Severe vibration or noise of the pump body:
Cause: pump installation is not strong or pump installation is too high; motor ball bearing damage; pump shaft bending or the motor spindle is not concentric, not parallel, etc..
Methods: the installation of a stable pump or reduce the installation height of the pump; replacement motor ball bearings; correction of the main shaft of the bend or adjust the relative position of the pump and motor.
4.The drive shaft or motor bearings overheating:
Cause: the lack of lubrication or bearing rupture, etc..
Method of treatment: fill in the lubricating oil or replace the bearing.
5. No water pump:
Cause: pump body and suction pipe is not filled with water; the water level is lower than the pump water pump pipe, water pipe burst and so on.
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.
