Product Description

Operating Principle of Pelton Turbine

Water turbines are turbomachines utilising 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 180° in the vanes. The impulse of the water jet is transmitted to the Pelton wheel.
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.
The structure easily installed in the basic hydraulic bench.
The unit composed of a small size Pelton turbine.
Be made of stainless steel.
Transparent plexiglass cover for flow visualization.
