1. When the stainless steel submersible pump is working, pay attention to the situation where the water level drops, and the submersible pump must not work out of the water.
2. When the use of submersible pumps is found to be stalled, there is little water outflow, there is noise, and thermal protectors frequently jump, and the pump should be stopped in time.
3, check the power supply voltage is too low or off, the cable is broken or missing phase.
4. Check whether the impeller is blocked or worn, whether the outlet chamber is blocked, the head is too high or too low, and the filter is blocked. If there is a fault, find a solution.
5, in case of stator winding burnout and other failures, shall be sent to the maintenance unit for repair, reassembly, sealing parts need to do air pressure inspection.
6. If it is found that the cable is damaged and replaced immediately, it can be used. For example, after the stainless steel submersible pump is used for pumping more viscous slurry, it should be put in clean water and run for several minutes. Wash the slurry in the electric pump, then wipe it dry. Anti-rust oil, stored in dry gout.
