长江葛洲坝十七万千瓦水轮发电机组,是目前国内最大的轴流式水轮发电机组。也是当前世界上最大的低水头大容量机组之一。研制这样的大型机组,在技术和制造上都存在相当大的难度。在整个研制过程中,得到了全国有关单位的大力合作。到全面投产前共完成55项重大科研项目,其中45项用于设计,主要有:为检验四叶片水轮机转轮的强度和结构的合理性,在陆水电站进行了水头23米的中间机组试验;为提高使用水头进行了叶片不锈钢材料和大型不锈钢叶片浇铸工艺的试验研究;为解决
The Gezhouba 170,000-kilowatt hydro-generating unit in the Yangtze River is the largest axial-flow hydro-generating unit in China. It is also one of the largest low-head and high-capacity units in the world. The development of such a large unit, there are considerable technical and manufacturing difficulties. Throughout the development process, it has received vigorous cooperation from relevant units across the country. A total of 55 major scientific research projects were completed before they were fully put into operation. Among them, 45 were used for design. The main ones are: To test the rationality of the strength and structure of the four-bladed turbine runner, an intermediate unit test of 23 meters head was carried out at Lu Shui Hydropower Station; In order to improve the use of the head of stainless steel leaves and large stainless steel blade casting process of experimental research; to solve
