Causes and solutions of insufficient liquid supply for Fire Pump Equipment

There will be various problems in the use of fire pump, but there is a very serious problem when there is no liquid supply, insufficient liquid supply or insufficient pressure, because the fire pump is mainly used for fire rescue, what is the cause of this problem? What are the solutions?

1. Impeller or pipeline is blocked. Solution: Check for obstacles.Fire Pump Equipment

2. The pump has no water injection or proper exhaust. Solution: Check whether the pump housing and inlet line are fully filled with liquid.

3. The packing or seal in the packing box is worn, so that the air leaks into the pump shell. Solution: Check packing or seal and replace as needed, Fire Pump Equipment check whether the lubrication is normal.

4. Speed is too low. Solution: Check whether the wiring of the motor is correct, whether the voltage is normal or whether the steam pressure of the turbine is normal.

5. The impeller is damaged. Solution: Check the impeller and replace it as required.

6. The system head is too high. Solution: Check the head of the system.Fire Pump Equipment

7. The position of the pressure gauge is incorrect. Solution: Check whether the position is correct, check the outlet nozzle or pipe.

8. The suction distance is too high. Solution: Check the existing net pressure head

9. The rotation direction is wrong. Solution: Check the rotation direction.

10. Insufficient suction head when pumping hot or volatile liquid. Solution: increase the suction head, consult the manufacturer.

11, the bottom valve is too small. Solution: Install the correct size of the foot valve.

12. Air production or inlet pipeline leakage. Solution: Check inlet lines for air pockets and/or air leaks.

13. The clearance of impeller is too large. Solution: Check whether the clearance is correct.

14. The diameter of impeller is too small. Solution: to the manufacturer to consult the correct impeller diameter.

From this point of view, the fire pump in daily life to carry out regular maintenance and repair, so as to avoid major problems, affect the normal use of equipment, serious wear and tear of equipment parts, damage to equipment, resulting in unnecessary losses.
