How to avoid malfunction of submersible pump？

Submersible pumps are very common in our lives, especially in agricultural irrigation, industrial and mining water supply, and water use in the high mountain areas. Do not neglect the maintenance of the submersible pump during the use of the submersible pump, otherwise it will easily lead to the submersible pump failure, affecting work efficiency and quality. Here are the precautions for the maintenance of the submersible pump. First, check the machine's switches, cables, electric shock protectors, etc. before using the submersible pump to ensure that these things are not abnormal and can work properly to start the submersible pump. In particular, pay attention to the grounding of the machine to avoid electric shock accidents. Second, the insulation resistance of the submersible pump should be checked regularly. If it is lower than 0.5 MΩ, it will not meet the requirements. It should be handled in time to ensure the normal operation of the machine. Third, check the drain hole and the hole regularly. If there is no abnormality, tighten it. When the submersible pump enters or discharges water, turn off the power and pull the rope on the ring.Fourth, the submersible pump works for more than 300 hours. It is necessary to carry out a sensitive water inspection. If the water discharged is less than 25 ml, it is necessary to check whether the rubber sealing ring has been damaged. It should be noted that the submersible pump cannot be buried in the river mud because there are many debris in the river mud, which will affect the working effect of the submersible pump.
