摘要
三峡左岸电站VGS(VOITH—GE—SIEMENS集团)机组推力轴承为小弹簧束支撑结构。小弹簧支撑推力轴承属弹性支撑,安装后不需进行受力调整。本文主要针对VGS水轮发电机组推力轴承运行情况,介绍了VGS水轮发电机组推力轴承的结构、运行及技术改造情况,分析了瓦温偏高的原因,并提出改进建议。
The thrust bearings of three gorges VGS unit are supported by many small springs. The springs have strong self-adjusting capability which make the segments don’t need to be adjusted after their installation. This paper mainly presented the structure, operation and technichal reconstruction of the VGS units thrust bearing, gave the reasons of the higher segments temperature and the improvement proposal.
