After the pump runs for the first four hours, the thermal insulation resistance of the motor should be closed and tested quickly.Its value should not be less than 0.5 megaohm.After the pump stops, it should be restarted after an interval of five minutes to prevent the water column in the pipeline from completely reversing and burning the motor due to excessive current.
- 3. After the pump is put into normal operation, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, working current and insulation resistance are normal. If the following conditions are found, the machine should be stopped immediately to troubleshoot.

- Unit disassembly:
- 1.untie cable rope, remove the pipeline part, remove the wire plate.
- 2.screw down the water bolt, put the water in the motor chamber.
- 3.remove the filter, loose the fixed screw on the coupling to fix the motor shaft.
- 4.screw down the bolt connecting the inlet junction with the motor, and separate the pump from the motor (pay attention to the unit cushion when separating, to prevent the bending of the pump shaft)
- 5.the disassembly sequence of the pump is: (see figure 1) inlet junction, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, and avoid bending and bruising of the pump shaft in the process of disassembly.
- 6.the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nuts, base, shaft head locking nut, thrust plate, key, lower guide bearing seat and double head bolt from the bottom of the motor in turn, and then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
- 7.unit assembly: before assembly, the rust and dirt of the parts should be cleaned, and the mating surface and fasteners coated with sealant, and then assembled in the reverse order of disassembly (the motor shaft moves up and down after assembly for about one millimeter), after assembly, the coupling should be flexible, and then the filter screen test machine. Submersible pumps shall be taken out of the well for dismantling and maintenance according to Article 5 after a year of operation, or less than a year of operation but two years of diving time, and the worn parts shall be replaced.
This product adopts advanced design and provides advanced storage suggestions to ensure long-term use effect.First of all, in winter, it is necessary to exhaust all the water to prevent freezing. In addition, the wire rolls should be placed well and tied up.Secondly, when storing, the environment without corrosive action and gas should be selected and the temperature should be kept below 40 °C. Finally, when not used for a long time, attention should be paid to prevent rust of submersible pump.These storage requirements will ensure that the product can maintain its performance status and prolong its service life for a long time.
