Safety requirements for submersible pumps

The submersible pump protection device is not sensitive and unreasonable, resulting in leakage and injury accidents.
A submersible pump refers to a pump that is used directly into the water, and the following points should be paid attention to when operating:
1. The shell of the water pump must be protected to zero (grounding), and a leakage protector (15mA×0.1s) is installed in the switch box.
2. The pump should be placed in a sturdy basket and placed in water, and the pump should be placed upright. When putting it into the water or lifting it out of the water, the power supply should be cut off first, and it is forbidden to pull the cable.
3. The distance from the center of the impeller to the water surface should be between 3~5m, and the pump body should not fall into the sludge or expose the water surface. [1]
