Mine submersible pump in the mine production is widely used, maintenance of mining submersible pump is also very important. Mine submersible pumps to maintain the most important thing is mine submersible pump motor maintenance.
Mine submersible pump motor electromagnetic part is basically the same as ordinary motors, therefore, the electromagnetic aspects of the fault and repair, but due to the specificity of explosion-proof motor. In the repair or transformation, shall comply with the following provisions:
1. The relevant personnel of the repairing unit should understand the national regulations, explosion-proof standards and the relevant provisions on the qualified products related to the maintenance work.
Second, the repair unit should have the repair of explosion-proof motor technology and equipment and the necessary inspection and test equipment.
Third, maintenance, should be ready for the necessary technical information.
Fourth, the motor repair is completed Before commissioning, should check the cable, relay protection and wiring system to ensure its intact and still meet the explosion-proof requirements.
5, for those engaged in explosion-proof motor maintenance personnel should carry out the necessary training.

After the inspection, inspection and repair inspection items after the repair, authorized or approved by the explosion-proof inspection unit, can be carried out in the repair unit; explosion-proof inspection units that are necessary items by explosion-proof inspection unit inspection.
7, after repair of the explosion-proof motor should be provided to the use of the following documents:
1) failure to check the situation;
2) Description of maintenance work;
3) replacement, repair parts catalog;
4) inspection, test results;
5) repair certificate.
8, not allowed to repair the pieces
1) parts made of glass, plastics or other materials of an unstable size;
2) fasteners;
3) The manufacturer or the explosion-proof procedures that can not be repaired parts, such as casting components.
9, after the repair does not affect the signs of explosion-proof performance of the repair, repair signs without repair.
10, after the repair of explosion-proof certification motor repair by the repair unit of the repair department issued a certificate of repair. The certificate shall include at least the name, type, specification, explosion-proof mark, name of the repairing unit, the number of the approved certificate, the number of the explosion-proof certificate, date of repair and so on. After the repair of the standard code-named GB3836.13-1997. Signs must be clear, durable, and resistant to chemical corrosion. Signs should generally be metal materials, permanently fixed after the repair of the motor, once again repaired, the repair should be removed after the previous repair signs.
