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 being completely reflowed and causing the motor to burn out due to excessive current.
4. （4）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, running current and insulation resistance are normal.If the following conditions are found, the pump should be shut down immediately to eliminate the fault:
5. 1 under the rated working conditions, the current exceeds 20%;
6. 2 the dynamic water level drops to the water inlet part, resulting in intermittent drainage;
7. 3 the submersible pump vibrates seriously or emits huge noise;
8. 4 the supply voltage is lower than 340 volts;
9. 5 a fuse is blown out;
10. 6 the water pipe is damaged;
11. 7 the thermal insulation resistance between the motor and the ground is less than 0.5 megaohm. The discovery of these problems need to be handled in time to ensure the normal operation of the pump, improve its reliability, so as to ensure the stable operation of the equipment for a long time.
