1. Wear of the pump body or seal: Wear of the pump body or seal is one of the main causes of water leakage.
2. Improper installation: For example, the pump shaft and the motor shaft are not concentric, the coupling is not aligned, etc.
3. Sand holes or cracks in the pump body: Sand holes or cracks in the pump body can also cause water leakage.
4. The packing is pressed too loose or too tight: Inappropriate packing compression can cause water leakage.
5. The pump body temperature is too high: The high temperature of the pump body can cause thermal deformation of the rubber seal, resulting in water leakage.
6. Impurities in the pump: Rusty water, sand and other impurities in the pump can cause seal failure and water leakage.
7. Mechanical seal damage: Mechanical seal damage is one of the common reasons, and the mechanical seal needs to be replaced.
8. Problems at the water pipe connection: Water leakage at the water pipe connection may be due to spring damage, water seal damage or failure to install a check valve.
How to deal with household water pump leakage:
1. Replace the pump body and seals: If the pump body or seals are worn, replace new parts immediately.
2. Reinstall the pump correctly: Ensure the coaxiality of the pump shaft and the motor shaft and the alignment of the coupling.
3. Repair or replace the pump body: If the pump body has sand holes or cracks, it should be repaired or replaced in time.
4. Adjust the packing tightness: Maintain the appropriate tightness of the packing to prevent it from being too loose or too tight.
5. Check and ensure that the pump's cooling system is normal: Ensure that the pump works at normal temperature.
6. Remove impurities in the pump: Regularly remove rusty water and impurities in the pump to prevent seal failure.
7. Replace the mechanical seal: If the mechanical seal is damaged, replace it with a new one.
8. Check the water pipe connection: Ensure the normal operation of the spring, water seal and check valve.
