1. Mechanical damage: Improper installation, repair or maintenance may cause the water pump shaft to bend or the seal to be damaged, which may cause the water pump to fail to work properly.
2. Material problems: The water pump material is not up to standard, and wear and corrosion may occur after long-term use, which will eventually lead to water pump damage.
3. Lack of lubrication: The water pump lacks necessary lubrication, which will cause increased wear of bearings and other components and shorten its service life.
4. Unstable voltage: Too high or too low supply voltage may cause damage to the water pump.
5. Impurity blockage: Too many impurities in the water may block the inlet and outlet of the water pump, affecting its normal operation.
6. Insufficient cooling: Too high water temperature may cause the water pump to overheat, affecting its performance and life.
Prevention and solution measures:
Check the power supply: Make sure the connector is firmly connected, the switch is in close contact, the fuse is intact, and the three-phase power supply is normal.
Clean up blockages: Regularly check and clean up impurities and blockages inside the water pump to ensure smooth inlet and outlet.
Replace damaged parts: Replace damaged bearings, seals and other parts in time to ensure the normal operation of the water pump.
Adjust voltage: Keep the power supply voltage stable to avoid too high or too low.
Enhance cooling: Ensure that the water pump has sufficient cooling to prevent overheating.
The above measures can effectively prevent and solve the damage problem of diesel engine water pumps and extend their service life.
