* It has large overflowing, good flow characteristic and high efficiency etc. Merits. * The runners are fixed or can adjust manual the efficient turbine of this kind can produce a large quantity of water flow which passes unimpeded. * All are horizontal type, the water enter into the turbine along the axial direction. * Compared with vertical axle flowing type units, the factory building is little in excavating amount, and hydropower station water conservancy project investment can save 10%- 20%, equipment investment saves 5%- 10%.
