摘要
立式水轮发电机组水轮机导轴承运行中发生甩油是一种常见现象,但瞬间大量润滑油被吸出现象极为少见,针对车坝三级电站#1机组运行中水导轴承因真空影响,润滑油瞬间被吸出现象进行了分析,并就同类型机组运行中,如何避免水导轴承突然缺油导致设备损坏提供了分析解决思路。
During the operation of vertical hydro-turbine units,oil spill of the guide bearing is a common problem.While in the No.1 unit in Cheba III Hydropower Plant,the lubricating oil of the water guide bearing is sucked out instantly due to the vacuum effect,which is rarely observed.Possible causes of the problem are analyzed and treatment measures are proposed correspondingly to avoid the equipment damage caused by the sudden shortage of lubricating oil.
