Gilkes Pelton Hydro Turbine
The Gilkes Pelton Hydro Turbine are medium to highhead free jet impulse turbines. The jet(s) strike the splitter edge of the double bucket and is turned through an angle of nearly 180 degrees before falling under gravity into the discharge channel or tailrace. Gilkes Pelton turbines are supplied as horizontal single and twinjet units or vertical 3, 4 or 6 jet units.
*It can operate on silt laden water with the minimum of wear. When wear does occur, spear tip, nozzle and deflector plate can be easily repaired and, after longer periods, the runner can be repaired by welding. All working parts are easily accessible through a detachable to cover.
*Speed-load control is usually carried out by the deflector, which ensures no pipeline surge even on full load rejection. When water economy is important, the deflector speed control can be augmented by follow-up closure of the spear.
*There is no danger of cavitation damage to the runner or casing.
