Descrição Geral

With the Francis Turbine unit, "FME28", designed by EDIBON, we study the Francis turbines commonly used when we have average flow rates and heights.

This unit consists on a miniature Francis turbine. The water inlet flow is controlled by a valve situated in the Hydraulics Bench (FME00) or Basic Hydraulic Feed System (FME00/B).

It includes a distributor with adjustable guide vanes that allow for control of the water angle of incidence in the turbine. To adjust the turbine distributor, the unit has a lever on the front of the same. It also has a braking system, connected to two dynamometers, that allows to vary the load supplied to the turbine.

The inlet pressure of the turbine is measured with a manometer situated at the turbine inlet. The feed or spiral chamber is provided with a damping cover and two tubes to avoid water overflow. Its name indicates that it is spiral-shaped and for this reason it is known as snail chamber. Thanks to its design, the water flows at a constant velocity without forming swirls. This way, there are no load losses. The turbine’s axis velocity is determined by a tachometer.
