A small number of users may encounter the phenomenon of the submersible pump suddenly stopping and not working during the use of the submersible pump. Without understanding the internal structure of the submersible pump, they may mistakenly believe that it is a quality problem with the submersible pump. So, what is the reason for the sudden shutdown of the submersible pump? Below are specific reasons for sudden shutdown of submersible pumps and solutions for sudden shutdown of submersible pumps for reference:
The submersible pump product used is equipped with a submersible pump non burning protection device inside. As long as the temperature rise of the submersible pump motor exceeds the preset temperature, the submersible pump will automatically start the protection system to stop running. Some users take ordinary submersible pumps to deliver hot water and run them for about 20 minutes before the submersible pump will automatically stop running. The submersible pump itself will generate heat during operation. If a normal submersible pump product is used instead of a high-temperature resistant submersible pump product, the submersible pump will suddenly stop. If a submersible pump product without a protection device is used, it will cause the motor to burn out. If the reason for the sudden shutdown of the submersible pump is due to the high temperature of the medium being transported, the solution to the sudden shutdown of the submersible pump is to recommend the use of high-temperature resistant submersible pump products, which can withstand temperatures up to 80 degrees Celsius.
If the submersible pump product used relies on a configured control cabinet to protect the submersible pump, such as the WQ submersible sewage pump, which usually relies on the control cabinet to achieve protection, the reason for the sudden shutdown of the submersible pump may also be due to the overcurrent of the submersible pump causing the air switch to trip, resulting in the phenomenon of sudden shutdown of the submersible pump. The solution to this sudden shutdown of the submersible pump is to increase the head of the submersible pump or install a valve on the outlet pipeline to control the water output of the submersible pump, in order to reduce the current of the submersible pump from exceeding the limit and avoid such phenomena.
If there are no protective measures for the submersible pump, and the submersible pump motor burns out due to phase loss, overheating, or overload, the submersible pump may suddenly stop. After repairing the submersible pump motor, a corresponding pump control cabinet should be configured to protect the submersible pump.
