7. Cable joint, cut off a 120mm rubber sleeve from one end of the outgoing cable and the matching cable with an electrician's knifethen stagger the length of the three core wires in a stepped shape, peel off a 20mm copper core, scrape of the oxide layer on theoutside of the copper wire with a knife or sand cloth, and insert the two connected wire ends in palirs.After tying the layer tightly with fine copper wire, solder it thoroughly and firmly, and sand of any. burrs on the surface. Then, forthe three joints, use polyvester insulation tape to wrap them in a semi stacked manner for three lavers. Wrap the two ends of thewrapping layer tightywith nyion thread,and then use a semi stacked method to wrap the tape for three layers. Wrap the outellayer with high-pressure insulation tape for three layers. Finally, fold the threestrands together and repeatedly wrap them for fivelayers with high-pressure tape. Each layer must be tightly tied, and the interlayer joints must be tight and fimm to prevent water frompenetrating and damaging the insulation, After wrapping, soak in water at room temperature of 20 ’c for 12 hours, and measurethe insulation resistance with a shaking table, which should not be less than 100M Ω

(5)This product is a portable water pump, with the characteristics of easy disassembly, the user can disassemble and clean the various components according to the following steps to maintain the normal operation of the pump. First of all to untie the cable tie, remove the pipeline part and take off the line protection plate. Then unscrew the drain bolt, discharge all the water in the motor chamber. Then take off the filter, loosen the fixing screw on the coupling fixed motor shaft. Then unscrew the bolt connecting the water inlet section and the motor, the pump and the motor separation (pay attention to the device leveling when separating, to prevent the bending of the pump shaft). The sequence of disassembly of the pump is: water inlet section, impeller, guide housing, impeller, check valve body. When disassembling the impeller, use special tools to loosen the cone sleeve fixed the impeller. In the whole disassembly process, pay attention to avoid bending the pump shaft and damage various parts. The steps of motor disassembly are: put the motor on the platform, remove the nut, seat, shaft head lock nut, thrust plate, key, lower guide rail from the bottom in order (tie rod bolt), then remove the rotor (pay attention not to damage the wire packet), and finally remove the connecting section and the upper guide bearing seat. Before assembly, the rust and dirt of each part should be cleaned, and sealant should be applied to each mating surface and fastener, and then the assembly should be carried out in the opposite order of disassembly (the movement of the motor shaft after assembly is about 1 mm). After assembly, the coupling should be flexible, and then the filter should be put on for machine test. 6. Submersible electric pump should be taken out of the well for dismantling and maintenance according to Article 5 after operating for one year, or less than one year, but the diving time has reached two years, and the worn parts should be replaced.
