Abstract

Abstract: In Weihai Hydropower Station, the temperature of the technical supplied water for the hydroelectric generating set was too high, and at summer, the cooling effects for the bearings of the hydroelectric generating set were poor. The bearing bush temperature and the oil temperature of the bearings and the air temperature of the air cooler all achieved the alarm value and were close to the temperature for emergency stop, which threatens the unit safe and stable operation seriously. The fault and the reasons of the problems were analyzed, and the defect eliminating measures were adopted. The fault does not appear again.

Key words: technical water supply, circulation, reason analysis, treatment method
