Causes Of Submersible Slurry Pump Motor Burnout

Aug 22, 2022

1. Since the head of the Submersible Slurry Pump is too low and the head of the pump is more than 5 meters higher than the actual working condition, the flow will be too large and the current will rise. The solution is to close the outlet valve of the small pump to increase the resistance. Decrease outlet flow control current.

2. The submersible pump motor needs to be submerged in water for use. The heat dissipation of the submersible motor mainly relies on water cooling. If the motor leaks out of the water without water cooling, the motor temperature will rise sharply, which will easily cause the motor to burn out.

3. If the liquid to be transported is hot water below 80 degrees, a hot water submersible pump must be used. The hot water submersible pump is usually a product with a stainless steel jacket and external cooling water cooling. The tap water cooling motor will definitely burn out because the medium temperature is too high to cool the motor.

4. Because the mechanical seal of the submersible pump is idling or corroded by the liquid, the mechanical seal is damaged, so that the water in the motor will also cause the motor to burn. It can be avoided if the corresponding water leakage sensor is matched with the control cabinet. Regular maintenance of submersible pump replacement seals is not recommended for this configuration.

5. The motor will also be burnt if the motor is missing due to other contact reasons such as the power cord is not in good contact.

For submersible pumps that have been immersed in water for a long time, the ground insulation and phase-to-phase insulation of the coil should be checked before the motor is started.

The water pump with the function of leakage and overload protection can be selected: high temperature resistant submersible pump
