水轮机转轮室因其衬砌上作用着渐变的荷载而容易受损。水利工程科研所自 2 0世纪70年代初就开始研制用于水轮机转轮室设计与检修的计算方法。拟制了转桨式水轮机转轮室检修的有效工艺 ,包括传统的金属结构以及利用复合材料的多层结构。研究了多层结构和复合材料在转轮室改造中的应用 ,与传统工艺作了某些比较 ,得出了一些结论。 Turbine runner cabins are susceptible to damage due to the graded loads acting on their linings. Hydraulic Engineering Research Institute since the early 1970s began to develop the design and maintenance of turbine runner room calculation method. An effective process for overhauling the rotor room of a paddle turbine is proposed, including a traditional metal structure and a multi-layer structure using the composite material. The application of multi-layer structure and composite materials in the renovation of the runner room was studied. Some comparisons were made with the traditional process, and some conclusions were drawn.
