Horizontal Unit
Horizontal type hydroturbine and generator each have a fulcrum(bearing) and connected by flywheel coupling. Diaxon horizontal turbine axial length is short, the structure is tight, installation and debugging is convenient and it needs to adapt three fulcrums (bearing) structure when bearing is under high load. Different from vertical type, horizontal type turbine and generator can be installed separately.

Horizontal type unit covers big plant area, volute and rotating part cause additional force in structure. So horizontal type is only appropriate for small and medium unit.
Part 1-Hydro turbine type and runner type
According to the power conversion methods of the runner, hydro turbine can be divided into reaction turbine(the hydraulic energy transfers to the runner with main enable power and kinetic power as supplement) and impulse turbine(the hydraulic energy transfers to the runner with full kinetic power).
