- The Pelton turbine should be a type of impulse turbine, such turbines convert the pressure energy of water into kinetic energy entirely in the distributor. During the conversion, the water jet accelerated in a nozzle and directed onto the blades of the Pelton wheel tangentially. The water jet is redirected by approx. 180″ in the blades. The impulse of the water jet is transmitted to the Pelton wheel.
- This model of a Pelton turbine should demonstrate the function of an impulse turbine. The experimental unit should consist of the Pelton wheel, a needle nozzle used as distributor, a band brake for loading the turbine and a housing with a transparent front The transparent cover should enable to observe the water flow, the Pelton wheel and the nozzle during operation.
- The nozzle cross-section and thus the flow rate are modified by adjusting the nozzle
- The turbine torque should be determined by force measurement on a band brake and is read on spring balances.
- The experimental unit should be positioned easily and securely on the work surface of the base module. The water should be supplied and the low rate measured by base module.
- Alternatively, the experimental unit can be operated by the laboratory
