蒲石河抽水蓄能电站采用单机容量为300MW立轴单级混流可逆式水泵水轮发电机组,伞式结构,整个机组轴线为刚性连接,轴系各部分加工及安装精度要求高。介绍抽水蓄能电站机组轴系各部件的结构,论述了发电电动机组轴系各部件、推力轴承、推力头的安装工艺和机组整体盘车及轴线调整的实践。通过对机组联轴及轴线的调整,经机组运行实测显示,3号与4号机组运行效果良好。
Pushihe pumped storage power station adopts stand-alone capacity of 300MW vertical single-stage flow reversible reversible pump turbine generator set, umbrella structure, the entire unit axis is rigidly connected, the shaft of the various parts of the processing and installation of high precision. This paper introduces the structure of each component of the shaft of pumped storage power plant, and discusses the installation process of each component, thrust bearing and thrust head of power generating unit, and the practice of unit turning and axis adjustment. Through adjusting the coupling and axis of the unit, the actual operation of the unit shows that the operation of Unit 3 and Unit 4 is good.
