水轮机导水机构密封结构的选择

Selection of seal structure of water-turbine disposal water mechanics

阐述了水轮机导水机构目前采用的各种类型密封结构特点,根据国外电站运行和设计经验,总结分析了每种密封结构如何适用于各水头段的大、中、小型机组,并详细地阐述了每种密封结构的性能,可为导水机构密封结构的选择提供可靠的依据。

The characters of all kinds of seal structure in water-turbine water disposal mechanics were discussed. According to the experience of operation and design in foreign countries, each and very seal structure was summarized and analyzed in order to adapt itself to large-scale, medium-scale and small-scale unit with all kinds of water head, the performance of each kind of seal structure was also explained in details, which provide reliable reference to selection of seal structure of water disposal mechanics.
