| Abstract: | Summarizes the study on the structure type of metal spiral case of water turbine and its application both at home and abroad, and introduces the advantages and disadvantages of some types of spiral cases in common use. Meantime, the study and development of structure types of spiral cases in Russia is presented in general. Besides, key technology of the pressure-maintaining spiral case by water filling and its application in Three Gorges project is demonstrated, providing technical support to the selection and design of spiral structure for the hydropower stations with high head and large install capacity. |
