Axial flow hydro turbine
　　Axial flow hydro turbine with fixed blade is suitable for the power plant with the low-medium head (usual 3-50m), big discharge, small variation in head and load. Its feature is that water flows through the runner in axial direction without a shift direction. It’s characterized by simple structure, vertical shaft installation, running stably under any working condition. The flume of the turbine can be classified into open channel, pressure trough, concrete spiral case, and totally enclosed metallic spiral case.
