1. Before using the submersible pump
, check whether the power supply equipment and power supply circuit can ensure the normal operation of the electric pump. Check whether the electrical wiring, control and protection devices are reasonable, safe and reliable, and whether the power supply voltage and frequency meet the conditions of use.
2. When a failure occurs, immediately turn off the submersible pump and check whether the circuit is stable, especially if there is a problem with its internal structure, and then you can judge whether it is a more serious problem.
3. After determining the problem, do not choose self-disassembly and repair, but choose a professional team to repair, so that you can better replace the parts or choose the appropriate maintenance method, because the self-disassembly may cause secondary damage and increase the maintenance cost.
