摘要
针对混流式模型水轮机研发中有关降低高部分负荷压力脉动的方法进行了探讨。通过不同转轮多个方案的模型试验和深入比较,掌握了不同形式泄水锥对混流式水轮机高部分负荷压力脉动的影响规律以及不同补气位置对长泄水锥混流式水轮机转轮压力脉动的影响,为电站运行中降低高部分负荷压力脉动提供了科学依据。
This paper discusses the methods of reducing pressure pulsation in high load zone of Francis turbine models. By way of deep studies anti experiments, we master the influence laws of different types of runner cone on pressure pulsation in high-load zone of Francis turhine runner, and the influence of different air-admission position on pressure pulsation of Francis turbine runner with longer runner cone.thus establishing a scientific basis for reducing special pressure pulsation zone with hydraulic turbine operation.
