 After installation of the underwater pump, it is necessary to recheck the insulation resistance and three-phase continuity of the switch, and check whether the connection between the instrument and the starting equipment is wrong. If there is no problem, you can start the test machine. After starting, observe whether the indication reading of each instrument is correct. If the rated voltage and current specified on the nameplate are exceeded, observe whether the pump has any noise or vibration. If everything is normal, it can be put into operation. Four hours after the first operation of the pump, it should be turned off and the thermal insulation resistance of the motor should be quickly tested, and its value should not be less than 0.5 megaohm. After stopping the pump, it should be restarted after an interval of five minutes to prevent the water column in the pipeline from completely reversing, resulting in the motor burning due to excessive current. 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 eliminate the fault:

1 the current exceeds 20% under the rated working condition.

2 the dynamic water level drops to the inlet section, resulting in intermittent drainage.

3 the underwater pump vibrates violently or emits huge noise.

4 the supply voltage is lower than 340 volts.

5 a fuse is burned.

6 the water pipe is damaged.

7 the thermal insulation resistance of the motor to the ground is less than 0.5 megaohm.

When disassembling the device, it is necessary to untie the cable bundle and remove the pipeline part and the line protection plate. Remove the drain bolt and exclude all water in the motor chamber. Remove the filter element and loosen the screw on the coupling fixed to the motor shaft. Unscrew the bolt connecting the water inlet section and the motor, and separate the pump and the motor (pay attention to placing the device horizontally when separating to prevent the bending of the pump shaft). The sequence of disassembling the pump is as follows: (see Figure 1) water inlet section, impeller, water inlet shell, impeller. Check the valve body, and use a special tool to loosen the cone sleeve fixed to the impeller when removing the impeller. In the process of disassembly, avoid bending the pump shaft and damaging various components. The disassembly process of the motor is as follows: (see Figure 1) put the motor on the platform, and remove the nuts on the screw (pull rod bolt), base, shaft head lock nut, thrust plate, key and lower guide rail - bearing seat, bolt, and then remove the rotor (be careful not to damage the wiring harness), and finally remove the connecting parts and upper guide bearing seat. Unit assembly: before assembly, the rust and dirt of each component should be cleaned, and the sealant should be coated on each mating surface and fastener, and then assembled in the opposite order of disassembly (the movement of the motor shaft after assembly is about one millimeter), after the assembly is completed, the coupling should be flexibly rotated, and then the filter element should be placed for testing. Each time the underwater electric pump has been used for one year, or less than one year but has been immersed for two years, it must be disassembled and inspected in accordance with Article 5 and replace the worn parts.
