Causes of overheating of the drive shaft or motor bearing: lack of lubricating oil or broken bearings. Solution: Lubricate or replace bearings
The reason why the mixed flow pump does not produce water: the pump body and the suction pipe are not filled with water; the moving water level is lower than the pump filter pipe; the suction pipe is broken. Solution: Eliminate the fault of the bottom valve and fill it with water; lower the device orientation of the pump so that the water filter pipe is below the moving water level, or pump the water after the water level rises; repair or replace the suction pipe.
The reasons for the excessive power consumption of the mixed flow pump are as follows: the speed of the pump is too high; the pump shaft is twisted or the pump shaft is not concentric or non-parallel with the motor shaft; the pump head is not suitable; the pump sucks in sand or has obstructions; the motor ball bearings are damaged, etc. Solution: Check the circuit voltage and reduce the speed of the pump; The manufacturer of the horizontal irrigation mixed-flow pump corrects the main shaft of the pump or adjusts the relative orientation of the pump and the motor; chooses a pump with a suitable lift; arranges sediment or obstructions; replaces the ball bearings of the motor.
The pump body of the mixed-flow pump vibrates violently or causes noise: the water pump device is not strong or the water pump device is too high; the motor ball bearing is damaged; the water pump main shaft is bent or is not concentric or non-parallel with the motor main shaft. Solution: Install the pump to stabilize or lower the height of the pump; Replace the motor ball bearing; Correct the twisted pump shaft or adjust the relative orientation of the pump and the motor.
