1. It may be that the power supply voltage of the user on -site is too low. The standard power supply voltage that cannot meet the demand for the submersible pump will cause difficulty in the launch of the submersible pump. Long will lead to the phenomenon of burning of the submersible pump motor. In this case, check the power supply voltage to the standard power supply to solve the problem.

   2. Due to the large flow diving pump motor, the power of the motor is too large. The user has other electric equipment on the spot. The configuration capacity of the user transformer is too small, resulting in the start of the submersible pump. Pump power.

   3. Because the electric cables of the submersible pump are relatively small and the cables are relatively small, the voltage drops are too large, so the submersible pump is difficult to start. Therefore, it is better to use a larger cable or a submersible pump from the transformer.

   4. The submersible pump uses the 380V power supply should be a three -phase power supply, and the power supply supplying the submersible pump is only two phases, so that the submersible pump will not start. This situation should be checked by a professional electrical tong -shaped current meter, or the current meter on the submersible pump control cabinet should be viewed. If it is found that it is a shortage of power supply, you should immediately cut off the power supply of the submersible pump; check whether the contacts in the cable joint, the wiring, and the power switch are not in contact. Burning. Check whether there is a disconnection of the power cable, and whether there is a problem with the cable joint; whether the motor winding has been burned and the specific reasons are excluded.

    5. If the three -phase current of the submersible pump is available, the current is large and stable, and the phenomenon that the submersible pump cannot be started, then the reason can only be found from the submersible pump. It may be that the bearing in the submersible pump is damaged and caused stuck. The impeller is stuck in the diving pump body into the diving pump into the diven. For example, the fiber rope is wrapped around the pump axis, which will make the submersible pump cannot be started. In this case, the submersible pump should be disassembled. Perform maintenance, replace new bearings and clean up debris. It may also be that liquid has corrosive sealing of the submersible pump mechanical sealing or the corrosion of the pump body. The water pump motor is damaged to the water pump motor. In this case, it is recommended to use the stainless steel submersible pump.
