叶片翼型好坏直接关系到水轮机气蚀、效率和运行稳定性。我厂ZZ500之所以能安全满载运行,甚至能超出限制线运行,使我厂多年来获得较好的电能效益,其中重要原因之一是水轮机转轮有较好的翼型,它能使水能充分地转换为机械能和电能。为了保持转轮完好的叶片翼型,避免因泥沙磨损、气蚀 Blade airfoil is good or bad directly related to turbine cavitation, efficiency and operational stability. One of the important reasons why our plant ZZ500 can run safely and fully and even exceed the limit line has made our plant better energy efficiency over the years. One of the important reasons is that the turbine runner has better airfoil, which can make water energy Fully converted to mechanical and electrical energy. In order to maintain the integrity of the runner blade airfoil, to avoid erosion due to sediment, cavitation
