The Role Of Bearing Oil Cooler in The Motor

Bearing oil cooler is one of the important parts of the hydro generator, its function is to establish thermal dynamic balance by heat exchange between bearing friction heat and cooler so that the temperature of the shaft tile can be stabilized in the normal operating range.

At present, most of the thrust bearings of hydropower plant units are replaced by fluoroplastic tiles from gold tiles, and the water-cooled tile structure is canceled. Therefore, the temperature of the tile surface of the thrust shaft tile, the temperature of the tile body, and the oil temperature of the thrust oil tank mainly rely on the oil cooler for heat dissipation.

Ensuring the normal operation of the oil cooler becomes a key link to ensuring the normal operation of the thrust tile and the unit.
