摘要
介绍了混流式水泵水轮机模型验收试验内容和主要性能参数的验收方式,对包括水泵高扬程区域的驼峰区和水轮机启动工况的不稳定"S"区等主要水力性能参数的试验验收问题进行了探讨,简述了无叶区压力脉动频率特性。
Model acceptance test content and main performance parameter’ acceptance mode of mixed flow pump turbine wereintroduced, main hydraulic performance parameters, such as hump of pump high lift region and S unstable region during turbinestarting, were discussed, after that, frequency characteristic of pressure fluctuation beside guide blade area were presented in briefly.
