1. 1.After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon. If everything is normal, it can be put into operation.
2. 2. After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
3. 3. After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from burning due to excessive motor current.
4. 4. After the pump is running normally, in order to prolong its service life, it is necessary to check whether the power supply voltage, running current and insulation resistance are normal on a regular basis.If the following conditions are found, the equipment should be shut down immediately to eliminate the fault:
5. - Under the rated working conditions, the current exceeds 20%.
6. - The dynamic water level drops to the inlet section, resulting in intermittent drainage.
7. - The submersible pump vibrates violently or emits noisy sounds.
8. - The power supply voltage is lower than 340 volts.
9. - There is a phase blown out in the fuse.
10. - The water pipe is damaged.
11. - The thermal insulation resistance between the motor and the ground is less than 0.5 megaohm.

1. 5. Disassembly device:
2. - Untie the cable, take off the pipe part and remove the line protection plate.
3. - Unscrew the drain screw and exclude all water in the motor chamber.
4. - Take out the filter and loosen the fixing screw on the coupling fixed to the motor shaft.
5. - Unscrew the bolt connecting the water inlet section and the motor, and separate the pump and the motor (pay attention to the level of the device to prevent the bending of the pump shaft when separating).
6. - The disassembly sequence of the pump is as follows: (see Figure 1) water inlet section, impeller, shunt shell, impeller, check valve body. When removing the impeller, use special tools to loosen the cone sleeve fixed to the impeller. In the process of disassembly, avoid bending the pump shaft and damaging various parts.
7. - The disassembly process of the motor is as follows: (see Figure 1) place the motor on the platform, and remove the nuts, base, shaft head lock nut, thrust plate, key, lower guide bearing. seat, and tie rod bolts from the bottom of the motor in order (see Figure 1), and then take out the rotor (be careful not to damage the wiring harness) and finally take out the connector and upper guide bearing seat.
8. - Assembly unit: before assembly, all parts should be cleaned of rust and dirt, and smear sealant on all the surfaces and fasteners, and then assemble 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 wear the filter for machine test. 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.
