Reasons and solutions of insufficient liquid supply for Gasoline Portable Fire Pump

There are various problems with the Gasoline Portable fire pump when it is used, but the problem is very serious 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. The impeller or pipeline is blocked. Solution: Check for obstacles.

2, the pump does not have water injection or appropriate exhaust. Solution: Check that the pump housing and inlet line are fully filled with liquid.

3, the packing or seal in the packing box wear, so that air leakage into the pump shell. Solution: Check the packing or seal and replace as needed, check whether the lubrication is normal.

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

5, impeller damage. Solution: Check the impeller and replace it as required.

6. The system water head is too high. Solution: Check the head of the system.

7. The position of pressure gauge is not correct. Solution: Check whether the position is correct and check the outlet nozzle or pipe.

8. Suction range is too high. Solution: Check the existing net pressure head

9. Wrong direction of rotation. Solution: Check the direction of rotation.

10, pumping hot or volatile liquid suction head is insufficient. Solution: increase the suction head and consult the manufacturer.

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

12, air 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 impeller diameter is too small. Solution: Consult the manufacturer for the correct impeller diameter.

Therefore, regular maintenance and repair of the Gasoline Portable Fire Pump should be carried out in daily life. The Gasoline Portable Fire Pump should avoid big problems, which will affect the normal use of the equipment, and cause wear and damage of the equipment parts in serious cases. Cause unnecessary losses.
