| Abstract: | During the reconstruction of distributor with high water head, contrast cavitation erosion between distributor and runner was analytially contrasted, meanwhile the cause of cavitation erosion was explored and its damage according to the related theory, then its solution was found. Moreover, the use of O-shaped seal ring in guide vane bearing neck seal was researched, and some experience in dealing with water leakage was got. |
