Introduction of Kaplan turbine
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
We also providing different kinds of water turbine generator:
1. Francis Turbine
2. Pelton Turbine
3. Inclined-jet water turbine
4. Cross flow water turbine
5. Tubular water turbine
Found in 1958, our factory in hydropower products has continuously been one of the national strategic turbine manufacturers in China since year 1995. It has now 246000 square meters ground area and 68000 square meters office building area. With over 500 workers and over 200 technicians and engineers, ADDNEW's invested factory is certificated by ISO9000-2000 and CE.
From the start of 2005 to the end of 2012, ADDNEW and our factory in Hunan, China have designed, manufactured and installed successfully over 170 small Hydroelectric Power Stations in Albania, Chili, Congo, India, Lithuania, Kazakhstan, Vietnam, Zambia and other overseas markets. The equipments adopted for those hydropower stations are unit-capacity from 800KW to 100MW and the total power generating capacities of each station ranging from 1600KW-200MW. All the completed stations are now maintaining their peak performance after their installations.
Why Choose Us (Addnew)
