Axial Flow Hydro Power Water Turbine Generator
Introducton of Axial Flow Hydro Power Water Turbine Generator
Hydro turbine generator is droved directly or indirectly by hydro turbine. The rotating speed is less than 1500r/min, with horizontal and vertical arrangement. Excitation mode with brushless and static silicon type. Components including stator, rotor, base frame, bearing, excitation motor or collecting ring. The outlet voltage from 400V to 13.8KV, and frequency could be 50Hz or 60Hz, output from 50Kw to 50Mw. Our generator are high efficiency, reliable, manufacture and tests all follow related IEC standards.
Application Range
Head: 20-200m Flow: 0.15-10m3/s
Most widely used turbine in the world. (70-80%)Applicable head and flow range is very wide.As a type of reaction turbine, the draft tube can be used to effectively increase net head.Peak efficiency is highest among all turbine types. (85-94%)Due to its complex design and large number of moving parts, maintenance and repair can be significant.
