2009 年中国电机工程学会年会 超临界集电环转子的安装找正及对九号瓦轴振的影响 1 2 2 田国成 金英强 赵乾 （1. 山东中实易通集团公司，济南 250002; 2. 大唐山东黄岛发电厂，青岛 266001 ） THE INSTALLATION AND ALIGNMENT METHOD OF SUPERCRITICAL GENERATOR COLLECTOR RING ROTOR AND IT’S INFLUENCE TO THE SHAFT VIBRATION AT NO.9 TILE 1 2 2 TIAN Guo-cheng JIN Ying-qiang ZHAO Qian 1 ( Shandong Zhongshiyitong Group Co., LTD , Jinan 250002; Datang Shandong Huangdao 2 electric power plant , Qingdao 266001)。 ABSTRACT: The dynamic characteristics of the 中发生“漂移”，形成附加质量不平衡激发轴振， 670MW collector ring rotor are quite sensitive to some 并被#9瓦负载小、轴承座动态位置不稳定等安装因 special factors of it’s installation and alignment. In 素放大。提出了现场检修工艺要求，通过适当加大 order to clarify what were the factors and how to 对轮连接力矩，调整轴承中心、间隙与标高等措施， control them, understand the abnormal vibration 结合高速质量动平衡彻底解决了#9轴振异常。 reason of No.9 tile , introduced the rotor’s installation 关键词： 670MW 超临界 集电环转子 安装 main point in site and analyzed the No.9 tile’s 与找正 振动 分析 abnormal vibration according to the vibration characteristics measured in the unit start/stop courses. 0 引言 Pointed out that the primary reason was the value of 某电厂#5机组是由N670-24.2/566/566型 rotor’s swing changed at some specical operating 汽轮机和QFSN-670-2型发电机组成的，由高 mode.
