【摘要】 本文从水锤基本微分方程式出发,按水锤压力在一相末达到最大值,然后维持不变的条件求得水轮机导叶最合理的调节序律。由于在计算中对水轮机考虑了较为严格的边界条件并计及了管道摩阻损失的影响,因而计算结果较一般手算方法精确。最后并给出了程序框图及计算实例。更多还原

【Abstract】 In this paper, the most rational regulation of the wicket gates of a water turbine is determined on the basis of the basic differential equations of water hammer, the pressure of which reaches the maximum at the end of one phase and then remains unchanged. Taking the boundary conditions for a water turbine into consideration in a strict way as well as the effect of friction losses in pipeline, the results of calculation by a digital computer are more accurate in comparison with those obtained from ordinary method. Lastly, a program flow chart is given together with a concrete example.更多还原
