Introduction of Pelton turbine

The Pelton type turbine is usually the preferred turbine for hydropower, when the available water source has relatively high hydraulic head at low flow rates, where the Pelton wheel is most efficient. They have the advantages such as compact structure, small size, high efficiency, low operation maintenance cost, low cost because of less excavation and less investments, etc. and disadvantages like inadequate energy recovery and lower efficiency than other types of turbines.


Application scope
Application scope of head: 80m~1200m
Runner diameter: 0.6 m ~ 3.5m
Installable capacity: 200KW ~ 80000KW

Theirs shaft arrangements are either vertical or horizontal and they may have single nozzle, twin or multi-nozzles. With characteristics such as high head, big capacity, multi-nozzle and good structure, etc..

Composition of Pelton turbine
Nozzle, runner, support parts and deflector parts.
Major components: rotating parts(runner, main shaft etc), nozzle parts(nozzle and related control), seat parts(seat, cover, spiral casing etc), pipeline parts(distributing pipe, brake piping, expansion joint etc), bearing parts and others. Core part is the runner and nozzle for structure
