AI Technical Summary
The existing high-power submersible pumps have poor bearing cooling, which leads to excessively high bearing temperatures, making them prone to damage, affecting equipment lifespan, and increasing maintenance costs.
A coolant channel is constructed inside the pump body of the submersible pump to cool the bearing using an existing cooling system or the pumping medium. The coolant channel is integrated with the main shaft hole fixing plate and is inclined to enhance the flow of the medium, which is especially suitable for axial flow pumps or oil-cooled pumps.
It effectively removes heat from the bearing, ensuring that the bearing operates within a reasonable temperature range, extending the service life of the equipment, and reducing maintenance costs.
