| 摘 要： | 从某电厂4号机组汽轮机轴瓦烧蚀问题入手,对该机组汽轮机油进行分析检测,得出油品运行中受热氧化是导致运行油油质劣化、汽轮机轴瓦烧蚀的主要原因,新油热氧化安定性较差是另一影响因素。据此,从多方面对运行汽轮机油的维护工作进行探讨,包括严格进行新油验收,提高机组检修质量,消除油系统缺陷和加强油质监督及维护等,以期提高汽轮机油管理及维护水平,确保发电机组运行的安全性及经济性。

| Abstract: | The analysis and detection on turbine oil for Unit 4 are carried out in consideration of the bearing bush erosion in a power plant. It concludes from the analysis and detection that the turbine oil quality deterioration and bearing bush erosion are mainly caused by the heated and oxidized oil in operation. Another cause is the poor thermal oxidation stability of the new oil. Therefore, multi-aspect discussion on the maintenance of turbine oil quality in service is taken, which includes strict new oil exam, unit overhaul enhancement, lubricating oil system defects elimination and the oil supervision and maintenance improvement to. The discussion is toenhance the oil management and maintenance, and ensure the safety and economy of the unit operation. |
