PELTON TURBINE – BRAKE FRICTION
This trainer can simulate a small scale Pelton turbine, especially designed for educational purposes.
It grants the possibility to constantly observe the system operation and its main components.
The turbine housing is partially transparent so that students can see how the turbine uses the inertia transferred by a water jet.
The water jet propels the turbine thanks to the recoil principle.
It includes several adjustable components that allow the changing of the parameters which can affect the mechanism.
The system has a built-in regulating valve of the water inlet allowing the functioning with different flows, as required.
The braking system is composed of dynamometers that allow the running at different revolutions according to the braking force exerted.
