Hydraulic Turbine Kaplan Type Water - China

price: contact company for price

The Kaplan turbine is an inward flow reaction turbine, which means that

the working fluid changes pressure as it moves through the turbine and

gives up its energy. Power is recovered from both the hydrostatic head

and from the kinetic energy of the flowing water. The design combines

features of radial and axial turbines. Its main parts usually include

Blades, hub, main shaft, runner cone, rotating mechanism.

Kaplan turbines are now widely used throughout the world in high- flow, low- head power production. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low- head applications that was not possible with Francis turbines.

According to whether the runner blade is movable or not in operation, it is divided into two categories: Axial movable- blade type and axial fixed- blade type.

Application scope of heads: 10m~70m

Runner diameters: 2.0m~11.0m

Installable capacity: 500KW ~ 200000KW

Specific ratio speed: 200 ~ 850

Kaplan turbines are now widely used throughout the world in high- flow, low- head power production.

Characteristics: Simple structure, Low cost.

Including Kaplan type, Propeller type and Thoma type.

* Kaplan type is with adjustable runner, the blade angle can change automatically according to the change of the water head and load, and ensure higher average efficiency, the efficiency of some Kaplan turbines are higher than 94% .

* Propeller type is with a vertical axle and fixed runner, blade angle can not be changed during operation mode, the efficiency curve is steep.

* Thoma type is between propeller type and kaplan type, according to the change of the water head and load, stop and adjustable blade, become to fixed blade operation.
