How to deal with single stage fire pump power consumption?

1. The water head is lower than the rated value and the liquid is pumped too much. Elimination measures: consult the manufacturer. Install the throttle valve and cut the impeller.
2. The direction of rotation is wrong. Elimination measures: Check the direction of rotation.
3. The running clearance between the wear rings is incorrect. Elimination measures: Check if the gap is correct. Replace the wear ring of the pump casing and/or impeller as required.
4. Impeller damage. Elimination measures: Check the impeller and replace it as required.
5. The bearing is not properly lubricated or the bearing is worn. Elimination measures: check and replace as required.
6. The speed is too high. Elimination measures: Check the winding voltage of the motor or the steam pressure delivered to the turbine.
7. The shaft is bent. Elimination measures: Straighten the shaft or replace it as required.
8. The rotating parts are blocked. Elimination measures: Check if the clearance of the internal wear parts is normal.
9. The stuffing box does not have the correct packing. Elimination measures: Check the packing and refill the stuffing box.
10. The liquid is heavier than expected. Elimination measures: check the specific gravity and viscosity.
