JD-10KW Variable Pitch Blades Wind Turbine (New)
Under the wind speed of 0m/s ~ 3m/s, the turbine blade remain static ,and the angle X1 formed between the blade and turbine plane is B° (X1= B°);under this angle ,the blade is most easily to be started up. As long as the wind speed reached 3m/s, the blades will begin to rotate, during the rotation, the outermost edge of the blade will be driven by the centrifugal force generated by the rotation of the blade to tilt toward the turbine plane, the aforementioned angle X1 will decrease until 0° when the blade is in parallel with the turbine plane; at this angle, the turbine has nearly reached it’s rated output power.
Variable Pitch Blades Device of JD-10KW Wind Turbine
When the wind speed is between 11m/s ~25m/s,the blade will keep adjusting it’s position forth and backward slightly to let the angle X1 fluctuate a little bit but maintain at around 0°roughly, so as to stabilize it’s rated power. Within the wind speed of 25m/s ~ 50m/s ,when the wind has exceeded it’s rated speed , the wind will keep drawing the blade by the centrifugal force,so the angle X1 will continue to decrease and turn into a negative angle X1= - B°(PS: B°and - B°is not the same),under this negative angle, the rotation of blade will produce a resistance on the rotation of turbine blade to slow down the rotation and protect the wind turbine from over speed operation, the maximum RPM of the turbine will be no more than 220 RPM.(A、B、C：3 Pcs Blades a、b、c：3 PCS centrifugal hammers)
