我国幅员辽阔,江河纵横,蕴藏着极其丰富的水力资源。优先发展水电,提供价廉而洁净的能源,是加快工农业建设的前提,也是“富民”、“升位”的基本保证。为此要求能制造出效率高,汽蚀破坏小,稳定性能好的水能机;同时还期待着能开发出结构更简单,制造更方便,性能更优良的新机型。广大水轮机研究工作者一方面努力提高现有机型的性能,如我厂研究所为龙羊峡、天生桥、二滩等电站研究成功的新转轮,水轮机比转速都有较大提高;同时也积极研究水轮机新机型。近年来,适用于不同条件的水轮机新机型不断出现,如天津电气传动设计研究所研制出适用于潮汐电站的双向贯流式水轮机就是其中一例,它们各有特色和创新。本文结合我省具体情况,将国内外新近研 With its vast territory and vast rivers, China boasts extremely rich water resources. Give priority to the development of hydropower and provide cheap and clean energy is the premise to speed up the construction of industry and agriculture, but also the basic guarantee of “enriching the people” and “upgrading”. For this reason, it is required to be able to manufacture hydropower machines with high efficiency, small cavitation damage and good stability, and also look forward to developing new models with simpler structure, more convenient manufacture and better performance. On the one hand, the majority of turbine researchers work hard to improve the performance of existing models. For example, the research institutes of our factory are new runners and hydro turbines that have been successfully researched by power plants such as Longyangxia, Tianshengqiao, Ertan and so on, Actively study new turbine models. In recent years, new turbine models suitable for different conditions continue to emerge. For example, Tianjin Electric Transmission Design Institute has developed a bi-directional tubular turbine for tidal power plants, one of which has its own unique features and innovations. This article combined with the specific situation in our province, will be new research at home and abroad
