Pelton turbine 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 through nozzles and strikes spoon-shaped buckets or cups arranged on the periphery of a runner, which causes the runner to rotate, producing mechanical energy. The runner is fixed on a shaft, and the rotational motion of the turbine is transmitted by the shaft to a generator.

The impulse type turbines are the best election for high head and small discharge hydraulic power resources. They have compact structure, small size, high efficiency and need fewer investments. They have been divided into Turgo and Pelton type.

The impulse type turbines made by Fuchun, are ranging from 80 to 1, 000m in water head, 200kW to 20MW in capacity and 0.55 to 2.3 in runner diameter. Theirs shaft arrangements are either vertical or horizontal and they may have single nozzle, twin or multi-nozzles.
