TH 01.1 – Friction Brake Pelton Turbine

The TH.01.1 equipment simulates an instalation in a small scale with a Pelton turbine. It has been designed with special emphasis on the didactic aspect of the same, being able to observe at all times the operation of the system and the different components that constitute it.

Description

The turbine housing is transparent so that you can see how the turbine uses the inertia that transfers a jet of water, which drives it by the principle of recoil.

The equipment is endowed with different variable components, which allows to vary the facings that affect the mechanism and thanks to it to be able to realize different tests for a better understanding of the student.

It has a regulating valve for water inner, which allows to work with different flow rates as required.

Regarding to the braking system, it is made up of dynamometers that allow the braking force to be operated at different speeds.

Learning Objectives
