The Importance of Protective Grounding of Submersible Pump
source:Industry News release time:2021-03-01 Article author:Rosit Popular:Air band saw
A submersible pump is a pump product that is connected with a pump and a motor, and works under the liquid at the same time. Why do the submersible pump need grounding protection?
The grounding protection of submersible pumps is very important. Only by adopting protective grounding can the personal safety during use be ensured. If there is no protective grounding, once the shell leaks, the water at the outlet of the submersible pump and the surface of the pumped water will become charged, endangering human life, and waste a lot of electrical energy.
If the metal shell of the submersible pump is connected to the grounding body that meets the standard, when the shell of the submersible pump leaks, the current flows through the metal shell of the submersible pump, the protective grounding wire, the grounding body, the earth, the working grounding wire of the transformer, and the power supply to form a closed loop.
When the leakage current is too large, especially when the live wire hits the shell, the protection device of the submersible pump can be activated, the fuse is blown or the air switch is tripped, and the power supply of the leakage submersible pump is cut off.
ROSIT is a leader in the global power tool service market. We take electric, pneumatic and hydraulic drive technology as the core. Our product categories mainly include hand tools, instruments, workshop equipment and fixed tools, labor protection products, industrial equipment,chemicals and so on.
