AI Technical Summary
When the inlet of a horizontal submersible pump is located between the motor and the impeller, the water cannot pass through the motor section, resulting in poor cooling, increased motor temperature, and a high failure rate.
Design a horizontal submersible pump external circulation cooling mechanism, which consists of a water injection pipe joint, a drain pipe joint, and heat dissipation elements to form an external circulation cooling system. It uses the temperature difference to circulate and cool the water inside the pump motor, and combines it with a filter element to filter impurities, thereby achieving internal circulation cooling of the pump motor.
It improves the cooling effect of the motor, reduces the failure rate, extends the service life of the equipment, and facilitates installation and maintenance through the bracket structure.
