Abstract  The design of the mechanical structure and hydraulic system of the tubular turbine governor has certain particularities. In order to improve the control performance of the tubular turbine governor, the tubular turbine governor of Chongqing Tongnan Hydropower Station is taken as the research object, and its mechanical structure and hydraulic system are designed. Firstly, the main mechanical components and the main adjustment functions and characteristics of the hydraulic system of the newly designed governor were introduced. Then, the structure and function of the main distributing valve with self-resetting function and the accident distributing valve that met the closing requirements of tubular turbine units were mainly analyzed. At the same time, a selection design method of the main distributing valve based on the relationship between the flow and the pressure drop was proposed, and the control window shape of its bushing was analyzed. Finally, through the governor field performance test, the rationality of the design of the mechanical structure and hydraulic system of governor was verified. The research results can provide references for the design of governors and the hydraulic system of turbines.

贯流式水轮机调速器的机械结构和液压系统设计

贯流式水轮机调速器的机械结构和液压系统设计具有一定的特殊性。为提高贯流式水轮机调速器的控制性能，以重庆潼南水电站的贯流式水轮机调速器为研究对象，对其机械结构和液压系统进行设计。首先，介绍了新设计的调速器液压系统的主要机械元件及其主要调节功能和特点。然后，重点分析了具有自复中功能的主配压阀和满足贯流式水轮机组关闭要求的事故配压阀的结构与功能；同时，提出了一种基于流量与压降关系的主配压阀选型设计方法，并对其衬套控制窗口的形状进行了分析。最后，通过调速器现场性能试验验证了其机械结构和液压系统设计的合理性。研究结果可为水轮机调速器及液压系统的设计提供参考。
