前言葛洲坝17万千瓦水轮机(以下简称葛洲坝大机)叶片的强度性能,很长时间以来是大家共同关心的问题。十多年来,许多兄弟单位做了大量的研究工作,取得了许多有价值的科研成果,从而解决了设计、生产中的一些疑难问题,使葛洲坝大机的制造、安装得以按期完成,并于1981年12月正式并网发电。葛洲坝电站的最高水头为27米,按过去生产惯例和我国水轮机型谱规范,在这一水头范围内,用
Preface Gezhouba 170,000-kilowatt turbine (hereinafter referred to as the Gezhouba Da machine) blade strength performance, for a long time we are all concerned about the issue. For more than a decade, many fraternal units have done a lot of research and have made many valuable achievements in scientific research so as to solve some difficult problems in design and production so that the manufacture and installation of the Gezhouba Grand Machine can be completed on schedule. December 1981 formally grid-connected power generation. Gezhouba Hydropower Station’s highest head of 27 meters, according to past production practices and China’s turbine profile specifications, in this head range, with
