The use of underwater pumps need to be carried out in strict accordance with the following steps: First of all, after the installation of the underwater pump, it is necessary to recheck the insulation resistance and the three-phase continuity of the switch, and check whether there are errors in the connection of the instrument and the start equipment. If there is no problem, you can start to test the machine. After the start, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has any noise or vibration. If everything is normal, it can be put into operation. The second step, after the pump runs for four hours for the first time, it should be closed and the thermal insulation resistance of the motor should be tested quickly. Its value should not be less than 0.5 megaohm. The third step, after the pump stops, it should be restarted after five minutes to prevent the water column in the pipeline from completely reversing, resulting in the motor burning due to excessive current. The fourth step, after the pump is put into normal operation, in order to prolong its service life, it is necessary to check the power supply voltage, operating current and insulation resistance regularly to see if they are normal. If the following conditions are found, the machine should be shut down immediately to troubleshoot:

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

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

3 the underwater pump vibrates violently or makes a lot of noise.

4 the supply voltage is lower than 340 volts.

5 a fuse burned. 6 water pipe damage.

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

The fifth step, the removal of the unit:

1 untie the cable tether, remove the pipe part, and remove the line protection plate.

2 screw down the water bolt and discharge all the water in the motor chamber.

3 remove the filter and loosen the fixing screw on the coupling fixed motor shaft.

4 screw down the bolt connecting the water inlet section and the motor, separate the pump and the motor (pay attention to make the unit level to prevent the bending of the pump shaft when separating)

5 the removal sequence of the pump is: (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 the impeller. In the process of removal, avoid bending the pump shaft and damage the various parts.

6 the removal process of the motor is: (see Figure 1) put the motor on the platform, and in order from the bottom of the motor bolt nuts, base, shaft head lock nut, thrust plate, key and lower guide bearing seat (iron rod bolt) on the connecting parts, and then take out the stator (careful not to damage the wire packet), and finally remove the connecting part and the upper guide bearing seat. Unit assembly: before assembly, rust and dirt on each component should be cleaned and sealant should be applied to each mating surface and fastener, and then the assembly should be carried out in reverse order of disassembly (the motor shaft moves about 1 mm after assembly), the coupling should be flexible after assembly, and then the filter should be put on for testing. Step six, after each use of the underwater electric pump operation for one year, or less than one year but immersed for two years, the disassembly and inspection should be carried out in accordance with the provisions of Article 5 to replace the worn parts.
