Clean water pump consumes a lot of power during operation, the reasons and treatment methods are as follows:
(1) Impeller wear ring or impeller and friction. The processing method of diesel engine fire pump is inspection and repair.
(2) The operation flow is too large. The processing method is to reduce the flow.
(3) The fluid density increases. The treatment method is to check the liquid density.
(4) The packing gland is too tight or dry friction. The treatment method is to relax and pack, check the water pipe.
(5) The bearing is damaged. The treatment method is to check repair or replace the bearing.
(6) The speed is too high. The solution is to check the driver and power supply.
(7) The pump shaft is bent. The treatment method is to straighten the pump shaft.
(8) The axial force balance device is malfunctioning. The treatment method is to check the balance hole and the return pipe is blocked.
(9) The axial clearance of the coupler is too small. The treatment method is to check the situation and adjust the axial clearance.
