Abstract

Abstract: In the operation of the water circulating pump motor of the Yunnan Huadian Kunming Power Generation Corporation Limited, the oil in the oil chamber of the upper guiding bearing pads was blackened. By analysis, the reason of oil blackening was found, and it's hazard was expounded. Aiming at the problems existing in overhaul of the water circulating pump motor, the treatment methods and the preventive measures were put forward.

Key words: shaft current, electrical corrosion, insulation pad, treatment method, preventive measure
