deep well hot water submersible pump work conditions are mostly above 40 ℃ water temperature, high temperature technical requirements for water lifting equipment, although the highest temperature of 125 ℃, but the temperature of its equipment is much higher than 125 ℃, but also to ensure the stability of its work and the useful life.
deep well hot water submersible pump use precautions
deep well hot water submersible pump cable connector should be strictly according to the map
1, before going down should be checked, whether the loosening of the screws, whether the cable break, the motor is turning over the water, the motor shaft, the pump can be rotated is flexible;
2, before going down to check the motor resistance should be more than 150 megohm;
3, the motor water to seriously prevent the fake full, should not be filled with water that is running;
4, protection switch and start the device should be required to match;
5, the motor running 2500 hours should be a major repair [replacement of wearing parts], 1500 hours should be a small inspection [maintenance];
6, wells with hot water submersible pump shutdown should be stored when the motor memory water finished;
7, is strictly prohibited do not understand the installation of brutal disassembly, repair should be in the factory or fixed-point repair shop;
8, prohibit frequent "open", "stop";
9, when installing deep well hot water submersible pump when the foreign body into the well;
10, in case of the following circumstances should be shut down maintenance:
(1) The current voltage exceeds the rated value.
(2) the flow was significantly reduced.
(3) the deep well hot water submersible pump intermittent water or sound show larger.
(4) protection switch frequently tripped.
(5) motor insulation, resistance below 0.5 megohm.
