本文介绍了轴流式水轮机轴向水推力试验研究的结果，分析了各种运行参数及叶栅稠密度，轮载体直径等几何参数对轴向水推力的影响，论述了其在协联工况及非协联工况下的变化规律，对其变化原理进行了探讨．作者发现了原计算式中单位轴向力参数在不同水头、不同空化系数条件下的不相似性，归纳出了新的相似规律及原型模型换算公式
In this paper, the axial thrust test results of axial-flow turbine are introduced. The influences of various operating parameters, such as the geometric parameters such as cascade density and wheel carrier diameter on axial water thrust are analyzed. And non-cooperative conditions under the law of change, the principle of change was discussed. The author discovers the dissimilarity of unit axial force parameters under different water head and different cavitation coefficient in the original calculation formula and sums up the new similarity rule and conversion formula of prototype model
