China Free Forging Steel Blade for Steam or Turbine

Name:Free forging 1.4021 ss420 Steel Blade for Steam Or Turbine
Description:
The Francis turbine are mostly suitable for hydro power station with medium or high head. The francis turbine we supply are compact in structure,
reasonable in design,convenient in operation and maintenance and excellent in efficency.
They are both vertical and horizontal shaft arrangement and can be vastly selected by the hydraulic power station.

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 spoonshaped 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 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.
Kaplan turbine also known as axial flow Turbine is developed in 1913 by the Austrian professor Kaplan.Its invention allowed efficient power production in low-head applications that was not possible with Francis turbines.
The feature of Kaplan turbine is the water flow passes through the runner axially.
Kaplan turbines are widely used throughout the world for electrical power production.
They cover the lowest head hydro sites and are especially suited for high flow conditions.
The tubular turbines are the best selection for exploitation of tidal power and hydraulic power with extremely low heads and extremely large flow
rates.
They have large discharge,high specific and high efficiency, and need less excavation.
They have been classified into Bulb, Pit, Siphon and S" types in the light of their structural types.
