1987年7月3～4日,上海发电设备成套设计研究所在湖北二汽热电厂的汽轮发电机组上首次成功地进行了轴系扭振和叶片动应力的相关试验,获得许多重要结果。二汽热电厂2号机系上海汽轮机厂制造的五万千瓦抽汽凝汽式机组(产品编号A170)该型机组共投运十余台,分布在吉林、江苏、河北、湖北、上海等地。自七十年代投运以来,曾发生过动叶片断裂事故。 From July 3 to July 4, 1987, Shanghai Power Generation Equipment Design Institute successfully carried out the related tests on the torsional vibration of the shaft system and the blade dynamic stress for the first time in the steam turbine generator set of the Hubei Steam Thermal Power Plant. Many important results have been obtained. Unit 2 of Steam Thermal Power Plant of Shanghai Steam Turbine Co., Ltd. The 50,000-kilowatt condensing steam condensing unit manufactured by Shanghai Steam Turbine Works (product No. A170) is equipped with more than 10 units and is distributed in Jilin, Jiangsu, Hebei, Hubei and Shanghai. Since the seventies put into operation, there have been moving blade rupture accident.
