我国有丰富的水利资源,长江、黄河……举世闻名。水利资源除用于运输、灌溉之外,最主要的是用来发电,水力发电除一次性投资大外,具有发电成本低、无污染等优点。 建水电站需要各种钢铁材料,其中水力发电机的心脏 水轮机的转轮和转轮叶片材料是至关重要的,其性能优劣直接影响发电机的发电效率和寿命。转轮和叶片工作条件很恶劣,一是受飞流直下的水流冲击和冲 Our country is rich in water conservancy resources, the Yangtze River, the Yellow River ...... world-famous. In addition to water conservancy resources for transport, irrigation, the most important is used to generate electricity, in addition to a one-time large-scale investment in hydropower, with low power generation costs, pollution-free and so on. Jianshui hydropower station needs a variety of steel materials, of which the heart of the hydro turbine wheel and runner blade material is crucial, and its performance will directly affect the efficiency and life of the generator power generation. Rotors and blades working conditions are very bad, first, by the impact of the water jet and red impact
