Product Description

Francis Turbine Trainer

The Francis turbine belongs to the reaction turbines which convert pressure energy of the working medium into kinetic energy in the guide vanes and in the rotor. Francis turbines are used for medium heads. The turbine power is controlled by adjusting the guide vanes. In practice, Francis turbines are used in run-of-river power plants and in pumped storage plants.

Learning Objectives And Experiments

 

  1. Investigation of the conversion of hydraulic into mechanical energy
  2. Determination of the mechanical power and hydraulic power of the turbine
  3. Determination of efficiency
  4. Recording of characteristic curves
  5. Investigation of the influence of the guide vane position
  6. Velocity triangles
