本文讨论了三峡右岸模型水轮机稳定性试验中的特殊压力脉动现象,通过多个方案不同转轮的模型试验和深入比较、研究,形成了对压力脉动的试验条件,包括测量链路的硬件条件、数据的处理方法、采样速率等内容比较一致的看法,并概括了特殊压力脉动现象的幅值、频率、流态现象、噪声等物理特征。为今后的试验研究打下了比较深厚的基础。
This paper discusses the special pressure pulsations in the turbine stability test of the right bank of the Three Gorges Project. Through the model tests and in-depth comparison and analysis of several runners of different models, the test conditions of the pressure pulsations are formed, including the measurement of the link hardware conditions, Data processing methods, sampling rates and other content of more consistent view, and summed up the special pressure pulsations of amplitude, frequency, flow phenomena, noise and other physical characteristics. For the future experimental study has laid a more profound foundation.
