Rules for using submersible pump safely

Submersible pump use safety regulations1, submersible pump should be packed in strong first basket into the water again, can be in the water around the perimeter of the pump set up strong protective fence. Pump should be upright in the water, the depth of the water should not be less than 0.5 m, should not be used in water with large amounts of mud.2, submersible pump into the water or the water, should be cut off power supply, it is strictly prohibited to pull cables or outlet pipe.3, submersible pump should be installed to protect zero and leakage protection device, working pump around 30 m within the surface of the water, cannot enter the people and animals.4, before the start of check and confirm:(1) pipe binding firmly;(2) put the plug such as gas, water and oil are tightening;(3) impeller inflow section without sundry;(4) electrical insulation is good.5, after turning on the power supply, should the first test run, check and confirm the direction of rotation is correct, there is no water running time may not exceed the instruction for use.6, often should observe water level changes, the impeller center to horizontal distance should be between 0.5 ~ 3.0 m, pump body into the sludge or surface is not allowed. The cable shall not wipe with wall, the wall.7, should comply with the regulations on the use of manual start voltage, electric current exceed the limits set by the nameplate, should stop the inspection, and shall not be frequent switch machine.8, submersible pump, need not when, shall not be submerged in water for a long time, should be placed in dry and ventilated room.9, motor stator winding insulation resistance shall be not less than 0.5 M Ω.
