1. improper selection. If the high lift pump is installed and used as a low lift pump, the pump flow rate will increase and the power consumption will be too high. Replace or select the appropriate pump, or close the gate valve on the outlet pipe. 2. Increased speed. When the power of the pump is selected, the speed of the power machine is higher than the specified speed, or the diameter of the water pump pulley is small, so that the pump speed is increased and the power consumption is excessive. The water pump pulley should be replaced. 3. The pump packing is too tight. Causes the water pump shaft friction to increase, the power consumption is too large. The packing should be adjusted. Turn the pump by hand until it is light and flexible. 4. Mechanical friction. The impeller of the water pump and the ring rotate to generate friction and consume too much power. The water pump can be turned before starting. If the situation in the world cannot be turned and it is heavy and rubs, you should find out the cause, troubleshoot, repair or replace the new one. 5. Bearing damage. Causes inflexible operation and excessive power consumption. To replace the new bearing. 6. The installation axis of pump and motor is not accurate. If there is no leveling or misalignment during installation and the power consumption is too high, the pump and motor should be recalibrated.
