Also called a free-jet turbine or Pelton wheel, a type of impulse turbine,named after L. A. Pelton who invented it in 1880. Water passes throughnozzles and strikes spoon-shaped buckets or cups arranged on the periphery of a runner, or wheel, which causes the runner to rotate, producing mechanicalenergy. The runner is fixed on a shaft, and the rotational motion of the turbine is transmitted by the shaft to a generator.Pelton turbines are suited to high head, low flow applications. Typically, to work this type of turbine, water is piped down a hillside so that at the lower end of the pipe it emerges from a narrow nozzle as a jet with very high velocity. The Pelton turbine can be controlled by adjusting the flow of water to the buckets.In order to stop the wheel a valve is used to shut off the water completely. Small adjustments, necessitated by alterations in the load on the generator, are more safely made by a device which deflects part of the water jet away from the buckets. | |
Pelton wheels are are used in storage power stations with downward gradients up to 2,000 meters and can contain up to 6 nozzles. Compare with the Francis turbine and the Kaplan turbine. |
