Tubular Turbine

The tubular turbines are the best selection for exploitation of tidal power and hydraulic power with extremely low heads and extremely large flow rates.They have large discharge, high specific and high efficiency,and need less excavation.They have been classified into Bulb,Pit,Siphon and "s" types in the light of their structural types. At present,HNAC has developed 16 varieties of tubular turbines,ranging from 2 to 25m in water head,200kW to 16mW in capacity,and 0.8 to 5.8m in runner diameter.They offered the best selection for exploitation of low head hydro-power resources in China.
