1. When working on stainless steel diving pumps, pay attention to the decline in the water level. The submersible pump cannot work out of the water.

   2. During use, it is found that the submersible pump is stopped, the water out of water, the noise, and the frequent jump of the heat protection device should be stopped in time.

   3. Check whether the power supply voltage is too low or power off, the cable is broken or lacking.

   4. Check whether the leaf wheels are blocked or worn, whether the water out of the water out room, the high or too low, and whether the filter is blocked. If there is a failure, find out the corresponding way to solve it.

   5. In case of failure such as the burn of the stator winding, it is necessary to send the maintenance unit for repair. When the assembly is re -assembled, the sealing site must be checked.

   6. If the cable is found to be damaged and replaced immediately, it can be used. If the stainless steel diving pump is used to pump up the more viscous pulp, it should be placed in the water for a few minutes. Rust -proof oil is stored in a dry place.
