Experience gained from these turbines are useful for the future large high-head Francis turbine design.
该水轮机的经验对今后大型高水头混流式水轮机的设计将是有益的。

To increase the head of bulb turbine, it is necessary to improve the runner blade design method and design highhead bulb turbine with good energy and cavitation coefficient performance high.
The impulse turbine unit is normally used in high water-head power stations, whose diversion system is long and is likely to cause pressure fluctuation.
