Safe Operation of Deep Well Submersible Pump

Deep well submersible pump unit with oil and water immersion in two ways, and in order to ensure the deep well submersible pumps to normal and effective operation, you should pay attention to the following precautions:
1, start to check whether the cable is normal, there is no fracture, cracking, abrasion and other phenomena, if there are several phenomena that should be immediately replaced, to prevent leakage phenomenon;
2, check the water pump pipe has cracked, the connection is solid;
3, deep well submersible pump into the water or hanging out of the water, you can not pull the cable to avoid cable breakage;
4, the pump into the water before the pump should be filled with water, in the venting, but also to check the pump start and idling is not normal. Its steering to the appropriate inspection to see whether the correct turn;
5, oil immersed motor immersed in water, it should first replace the sealing element into the water after; flooding motor should be filled with water after the bolt fastened and then into the water;
6, should check whether the motor insulation resistance is normal, the normal value should not be less than 5 megohm;
7, deep well submerged pump unit into the water should be placed vertically, but not tilted or tilted put;
8, the pump unit start-up voltage must be normal, the power of the film should be rated about 5% of the voltage;
9, deep well submersible pump delivery medium should not contain a lot of sediment or mud, sediment content can not be too high, and the pump running for some time, should be on the pump and motor cavity should be cleaned;
10, the pump used in the lift should be within the rated head, so that can improve the efficiency of the pump, energy saving, can effectively avoid the pump motor overload operation, which makes the motor damage;
11, the pump if not for a long time, it should be cleaned and painted with rust-proof paint, placed in a dry environment, and the pump motor should be its cavity water dry and dry.
