(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.
