| Abstract: | The working principle and structure of hydro-turbine main shaft seal were presented.The seal leakage reason was analyzed.By converting original seal water piping and improving seal water pressure,the relatively severe water leakage problem was solved.The converted main shaft seal runs smoothly,and the leakage amount is under the design range. |
