The choice of the submersible pump before use is very important. Consider the actual situation of the water source, working time, pumping volume, etc., and comprehensively determine the model of the submersible pump selected. Just like the requirements of the environment, it is necessary to have a safe and reliable power supply, the drop of the outlet pipe on the water surface of the pool is less than the lift, and the water source is preferably clean. When the submersible pump is in normal use, it will inevitably lead to many unexpected situations. In any case, should the submersible pump be stopped immediately?
1) The submersible pump current is unstable and suddenly exceeds the rated current of the motor.
2) If the insulation resistance of the motor is less than 0.5 megohm, the grid voltage is insufficient and less than 5% of the rated voltage.
3) The amount of water is not normal, the intermittent water is discharged, and the sediment concentration is increased.
4) The fuse is burned out and the water supply line is damaged.
5) The unit has obvious noise and vibration.
