600MW大型水轮发电机组推力轴承瓦温和油温高原因分析及处理

Reason analysis and treatment of high temperature of thrust bearing bush and oil for 600 MW large-scale hydroelectric generating unit

对600MW大型水轮发电机组推力轴承瓦温和油温偏高现象进行了分析,找出了导致瓦温和油温高的原因,并采取了优化油循环结构及提高油循环速率等主要措施,取得了良好效果,供同类型机组处理此类故障参考。

The study analyzed phenomenon of high temperature of thrust bearing bush and oil for 600 MW large-scale hydroelectric generating unit,found out reason which caused high temperature of bush and oil,and adopted main measure such as optimize oil circulation structure and increase oil circulation rate,and gained well result which can provide reference for same category unit to handle such kind of fault.
