Small hydro power generation(Scroll turbine)

The most important equipment of small hydro power system is water turbine.In order to improve the economic efficiency, the selection of water turbine to the characteristics of the plant should be prioritized.

Scroll is a whirlpool. Scroll aberration turbine is a hydro turbine with two scrolling parts.By relatively moving to obtain the rotational force, although the principle has been known for a along time, if can not be put to practical use due to difficulties in manufacturing, It has been put into practical use due to development of working techniques and applied to a compressor and expander manufacturing technology.
