1, for the submersible pump should do some necessary checks before starting: whether the rotation of the pump shaft is normal, whether there is a stuck phenomenon; whether the position of the impeller is normal; whether the cable and cable plug is broken, scratched and broken. During operation, pay attention to the change of voltage, which is generally controlled within ± 5% of the rated voltage. In addition, the position of the pump in the water is very important. It should be selected as far as possible in a place with abundant water, no silt and good water quality. It should be suspended vertically in the water (note: never use cable to suspend it). It is not allowed to be placed horizontally, so as not to fall into mud or be blocked by suspended substances, resulting in sharp reduction of water output or even failure to pump water.

2. Water pump maintenance Once the water pump fails, do not disassemble it yourself. Because when disassembling by oneself, one is that one does not know where the fault is, causing blind disassembling. Second, there is no special tool and often damage the original intact parts. The best way is to go to an experienced, large-scale maintenance point for maintenance, and timely replacement of "over-age" parts and some wearing parts. Under normal circumstances, the pump should be repaired every six months.

3, long-term shutdown of the electric pump, the pump should be timely lifting away from the water source, and emptying the water in the pump, especially in the cold winter. Then place it in a dry place. Conditional users can also apply butter to the key parts of the water pump and add lubricating oil to the bearing to prevent parts from rusting. In addition, the non-use period of the pump is not the longer the better. If it is not used for a long time, it will not only easily rust the parts, but also reduce the service life of the pump.
