Operating Principle of a Pelton Turbine:
Water turbines are turbo-machines utilizing water power. The Pelton turbine is part of the free-jet turbines resp. impulse turbines which convert the pressure energy of water into kinetic energy entirely in the control device. During the conversion, the water jet is accelerated in a nozzle and directed onto the vanes of the Pelton wheel tangential. The water jet is redirected by approximately 180degree in the vanes. The impulse of the water jet is transmitted to the Pelton wheel. Operating Principle of a Pelton Turbine is the model of a Pelton turbine demonstrating the function of an impulse turbine. The experimental unit consists of the Pelton wheel, a needle nozzle used as control device, a band brake for loading the turbine and a housing with a transparent front panel. The transparent cover enables you to observe the water flow, the wheel and the nozzle during operation. You can modify the nozzle cross-section and thus the flow rate by adjusting the nozzle needle.
