Abstract:The 300MW pump storage units are adopted in Pushihe Pumped Storage Power Station with umbrella-shaped structure. The whole unit axis is rigid eonnection, and the processing and installation accuracy of each part of shafting is high. The structure of shafting components for pumped storage units are introduced. The practices in shafting components of pumped units, thrust bearing, installation of thrust cone and integral barring as well as axis adjustment are discussed. After shafting installation and axis adjustment for pumped storage units, unit 3 and unit 4 in Pushihe Pumped Storage Power Station are operating satisfactorily

蒲石河抽水蓄能电站水泵水轮机由哈尔滨电机厂生产制造,机组额定功率300MW,额定转速 333.3r/min,为单级混流可逆式机组,推力部分在下机架上,为伞式结构。由于整个机组轴线全部为刚性连接,不仅对轴系各部分的加工精度要求商,而且为了控制机组轴线摆度,对安装工作也提出了更高要求。轴系的安装质量主要体现在轴系各部位的连接、推力轴承的安装调整、盘车和轴线的调整。 2
轴系各部位联轴
整个机组轴线全部为刚性联接,共4个联轴面。
机组整个轴线如图1所示。【收稿日期】2012-03-08
