蓄能机组轴线问题及机组运行摆度偏高分析处理

Analysis and treatment of abnormal axis and throw of a pumped storage unit

十三陵蓄能电厂针对机组运行中水导摆度过大的问题,特别是2号机组在安装期间进行过加垫调整轴线,对全厂4台机组的轴线进行了彻底检查。本文通过对2号机组的轴线调整阐述了可逆式、高转速、高水头蓄能机组的轴线调整,从各方面分析了影响机组运行摆度的可能原因。

In order to solve the problem of over-throw of units in Shisanling Pumped Storage Plant,the axes all of 4 units were inspected. The axis of No. 2 Unit was adjusted by padding during installation. This paper discusses the axis trimming of a reversible,high-speed,high-head storage unit: and analyzes the causes of affecting the throw.
