Key Causes of Safety Accidents of Stainless Steel Submersible Pump in Deep Water Well

What problems should be paid attention to for the switching power supply motor of stainless steel submersible electric pump

1, grounding device processing-stainless steel submersible pump to carry out grounding protection is a mandatory requirement of national standards. If there is no grounding protection, once the shell is electrified, it will cause the water at the outlet of the pump casing and the water quality to be electrified, which will not only threaten personal safety, but also spend a lot of electromagnetic energy. However, if the grounding device is connected according to the national standard, when the pump shell is short-circuited, the current value will build a closed loop through its shell, protective grounding wire, grounding body, land resources, transformer and switching power supply. Once the leakage current is unstable, the pump casing will have a protective equipment posture, disconnect the electric switch power supply.

2, equipment leakage protection switch-most of this kind of pump shell will work in the water, once the electricity will inevitably lead to electromagnetic energy consumption, and even cause safety accidents. If the leakage protection switch is installed, if the power supply value of the pump casing exceeds the preset value of the leakage protector, the protection device will disconnect the switching power supply.

3, the power supply current status after the boot-current is too large, too low will make the pump shell temperature increase is too high, reduce the use of time limit, and even damage to the pump shell. According to the low-voltage power supply line is relatively long in rural areas, the voltage at the end of the line is low and the current at the first end is too large. Therefore, in the process of using stainless steel submersible pump, the operator must query the power supply current value anytime and anywhere. If it exceeds 10% of the rated current or 20% of the rated voltage, it needs to be shut down in time.
