| Abstract: | With the development of low-head run-of-water hydropower station, the bulb turbine units with such advantages as little investment, short installation period, convenient maintenance becomes widespread used. The break-off of the sealing water flow in the principal axis of the tubular turbine in the hydro-junction of Guangxi Changzhou becomes the main reason of the unit shutdown. |
