Common failures of fire pumps, analysis and preventive measures!

Fire pumps are important equipment to ensure the normal operation of fire protection systems, but some failures often occur.

The following are some common fire pump failures, analysis and preventive measures:

1. The pump is difficult to start or cannot start:

- Analysis: It may be a power failure, motor damage, control circuit failure, etc.

- Preventive measures: Regularly check the power supply line, motor and control circuit to ensure their normal operation; perform regular maintenance and clean the motor and control equipment.

2. The pump makes too much noise when running:

- Analysis: It may be bearing wear, impeller imbalance, loose pump body, etc.

- Preventive measures: Regularly check the bearings, impellers and pump bodies, and replace worn parts in time; perform regular balance corrections to ensure the normal operation of the pump.

3. Pump leakage:

- Analysis: It may be aging of seals, damage to the pump body, loose connections, etc.

- Preventive measures: Regularly check the condition of the seals and replace aging seals in time; regularly check the pump body and connections to ensure they are intact.

4. Unstable pump pressure:

- Analysis: It may be due to blockage of the water inlet pipe, accumulation of scale inside the pump body, wear of the pump impeller, etc.

- Preventive measures: Clean the water inlet pipe regularly to prevent blockage; clean the inside of the pump body regularly to prevent accumulation of scale; check the pump impeller regularly and replace worn parts in time.

5. Pump overheating:

- Analysis: It may be due to too long operation time of the pump, failure of the cooling system, accumulation of scale inside the pump body, etc.

- Preventive measures: Arrange the operation time of the pump reasonably to avoid too long operation; check the cooling system regularly to ensure its normal operation; clean the inside of the pump body regularly to prevent accumulation of scale from affecting heat dissipation.
