Hydroelectric Vertical Francis Turbine Generator

Francis turbine is a kind of turbine suit to water head 20-300meters and with certain suitable flow.
Vertical Francis turbine unit, with vertical shaft, metal spiral case or concrete spiral case. With adjustable guide vane, and stay ring etc parts, are suit to runner diameter bigger than 1000mm. Our engineer will select the most suitable Francis turbine for your hydro power project.

Generators
We selects only high quality generators to include with our systems, ensuring efficient operation, long life, and low maintenance. In most cases, the rotating speed of the generator is 1800 rpm or slower to maximize longevity and minimize efficiency losses in the drive system.
Governors
Governors can range from relatively simple devices to highly complex systems for larger, grid-connected hydro projects. Regardless of complexity, however, the basic function remains the same: maintain a constant RPM at the generator, and therefore a constant voltage and frequency. We will be happy to discuss your site requirements and recommend the appropriate governor type.
Needle Nozzle Control
If flow changes frequently, the optional needle nozzle can simplify adjustments and eliminate the need to shut down the turbine. It permits infinitely variable flow adjustment, from zero to maximum design flow, while the turbine is running. Forster needle nozzles have stainless steel needles and beaks for extremely long life.
