What should I do if the submersible electric pump burns out, what causes it, and the reasons and solutions for the problem are summarized as follows:
1. The grounding wire is connected to the wrong power source. The cable of the submersible pump has four cores, so be careful not to use the grounding wire as a power line.
2. The mechanical seal of the stainless steel submersible pump is broken and leaking. Regularly check the insulation resistance of the submersible pump with a megohmmeter, and take timely maintenance measures when the insulation resistance drops to prevent the motor from burning out.
After the cable breaks, water enters the cable, and the insulation resistance of the submersible pump should be checked regularly.
When the impeller is stuck and cannot rotate, and the current is higher than the rated value, over time, the stator winding of the submersible pump will quickly burn out.
5. The two ends of the stator winding are in contact with the casing, causing the winding to break through to ground.
6. The stainless steel submersible pump starts and stops too frequently.
7. The dehydration operation time of stainless steel submersible electric pumps is too long, and the dehydration operation time of submersible electric pumps can only be about 1 minute. As time goes by, the temperature of the electric pump will increase due to poor heat dissipation.
8. During phase loss operation, the submersible pump is generally in a braking state with a current much higher than the rated value. At this time, the temperature of the submersible pump winding rises, and over time, the stator winding will be burned out.
The sudden failure of a submersible electric pump can be caused by the following reasons
1. Power outage may also be due to the sudden failure of the submersible pump to operate.
The solution to sudden non operation of the submersible pump is to first check if the power supply of the submersible pump has been cut off, identify the cause of the power outage, promptly troubleshoot and restore power supply.
The reason for the sudden non rotation of the stainless steel submersible pump may be due to the tripping of the control and protection switches of the submersible pump.
The main reason for the tripping of the control switch is that the submersible pump is damaged during operation or the submersible pump motor is overloaded. The solution to the sudden non rotation of the submersible pump is to first measure the insulation resistance of the submersible pump motor, check whether the stator winding of the submersible pump motor is damaged, and whether other components are damaged. If other components of the submersible pump are damaged, causing the stator winding to be damaged or damaged due to overload or short circuit, the damaged components and stator winding should be repaired. If the submersible pump is not damaged, the tripping of the control protection switch is caused by the overload of the submersible pump. Check whether the power supply voltage and the service head of the pump are within the specified range, adjust the power supply voltage and the operating conditions of the submersible pump to the allowable range, and avoid submersible electricity. Pump overload and control protection switch tripping.
