How to repair the fault of stator winding of submersible electric pump

The repair method for the fault of stator winding of submersible electric pump is as follows:
(1) the lead and a bridge line open welding repair if find out the breaking point is lead or coil open welding welding part of the bridge line, can clean the desoldering, then stay in welding area near the coil on the ground lay a layer of insulating paper, prevent damage from the solder to shed the coil insulation, and then carries on the repair welding.
(2) the stator winding end coil burn out of repair of the stator winding end burn out one or several wire coil, the coil must be heated to 130 ℃, to soften the insulation and then turns to pry up will burn out, distinguish each wire's end, with the same specifications of the wire connection on the wires burn out endpoint, good connection after welding, after welding, insulation bandaging, and paint processing.
(3) slot wire burn out fault repair groove wires burn out, the processing method and the methods of dealing with the coil of coil grounding or short circuit, also need to heating coil, softening insulation, then eliminate slot wedge, then burn out by groove of the coil, the ends of the wire turn that will burn out by the end cutting, to move welding points at the end, avoid trough in crowded.The new wire of the same specification is welded, and the insulation is wrapped in the welding place. Finally, the finished wire turns are inserted into the groove, the insulation paper is padded, the groove wedge is inserted, and the insulation paint is applied.
