Why submersible pump not working?

A small number of users will encounter the phenomenon that the submersible pump stops suddenly and does not work during the use of the submersible pump. If it does not understand the internal structure of the submersible pump, it will be mistaken for the quality of the submersible pump. The following is a reference for you to share the specific reasons why the submersible pump does not work suddenly and the solution to the sudden stop of the submersible pump:

This article contains the following:

• Downtime due to high temperature

• Overcurrent caused the submersible pump to stop

• Solution

• Other possible reasons why the submersible pump does not work

1.Downtime due to high temperature

The submersible pump products used, such as stainless steel submersible pump products, are equipped with a submersible pump burn-in protection device. As long as the submersible pump motor temperature rise exceeds the preset temperature, the submersible pump will automatically start the protection system to stop the submersible pump. After the pump is used to deliver hot water, the submersible pump will automatically stop running after about 20 minutes. The submersible pump will heat during operation. If the submersible pump is not a high temperature submersible pump product but an ordinary submersible pump, the submersible pump will suddenly appear. If the submersible pump product without protection device is used, it will cause the motor to burn down. If the reason why the submersible pump stops suddenly is caused by the high temperature of the conveyed medium, the solution to the sudden stop of the submersible pump does not work is to recommend the use of high temperature resistant submersible pump products, the temperature of the high temperature submersible pump can be up to 80 degrees.

2.Overcurrent caused the submersible pump to stop

If the submersible pump products used rely on the configured control cabinet to protect the submersible pumps. For example, WQ submersible sewage pumps usually rely on the control cabinet to achieve protection, then the reason why the submersible pumps stop suddenly and do not work may also be caused by the submersible pump overcurrent The phenomenon that the submersible pump suddenly stops due to the air switch tripping. The solution to this submersible pump's sudden shutdown does not work is to increase the submersible pump's head or install a valve on the outlet pipe to control the submersible pump's output to reduce the submersible pump's current Do not exceed, it will avoid the emergence of such phenomena.

3.Solution

Since the submersible pump does not have any protective measures. The submersible pump motor is burnt down due to lack of phase or over temperature and overload. The submersible pump suddenly stops. After the submersible pump motor is repaired, the corresponding pump control cabinet should be configured to protect the submersible pump.

4.Other possible reasons why the submersible pump does not work

Poor cable contact, excessive current caused by blocked rotation, reverse rotation, and low voltage will cause the submersible pump to sometimes not work. You can determine where the problem is based on current and water output.
