Because the submersible pump cable fixed way is not correct, the water flow caused cable and boom long-term friction when submersible pump running, resulting in damage.submersible pump running in the motor coil will heat, the motor internal temperature is high, submersible pump After stopping the operation, the internal temperature of the motor chamber will drop, the motor outside the water will be broken from the cable along the cable was sucked into the motor inside, because the number of submersible pumps and the time is not the same, so the degree of water leakage inside the submersible motor Different. But also because the drainage station is running a small number of times each year, and each time the operation is also short, and the submersible pump is insulated, the electric coil is not short-circuit burned, but the motor internal water, the motor is running unbalanced, causing the motor running current higher, seal damage, oil leakage.
As the cable damage caused submersible pumps in the motor leakage is a more common accident, we should be targeted to take preventive measures.
