Product Detail

Model No.: FSC-5KW
Brand Name: VILLE


Speciality:Low wind speed start,Changeable propeller pitch control,The system work safer.
1. FSC-5kw changeable propeller pitch wind generator brief introduction
 Ningbo Fengshen Fengdian Science and Technology Co.,Ltd have successfully developed various pitch wind turbine, which is the first one who apply pitch technology into 5kw wind turbine. the system adopt mechanical centrifugal pitch, track rotation and automatically adjust blades' pitch,to keep rated rotation, ensure steady voltage output and safe working.
2.The speciality of the pitch control wind turbine
  Compare with exist technology ,the speciality of this system as follows:there is centrigugation pitch control system on  the hub of the wind wheel .When the rotate speed of the wind wheel is over the rated rotate speed under the performance of centrifugation pitch control system. The system will adjust the rotate speed of the wind wheel and make sure that the wind wheel will not run over speed in to much. And ensure the wind turbine can run smoothly under the rated wind speed. It will protect the blade wind generator and control system ,and they will not be destoried even it is in high wind speed. At the same time it makes the wind turbine can be widely used at low and high speed. While there is baffle in front of the hinge cover. When the spring releases its pressure, the system can prevent the axis from over reposition. It can ensure that the reposition angle of the axis more accuracy. So that the centrifugation pitches control system can control the rotate speed exactly. Furthermore ,the structure of the whole system is briefness and easy for production.
  All the insiders know that all the shape of wing have a critical angle of attack, under this angle attack ,the blade have a maximum valuable rate. So that the wind wheel can work with high efficiency .This is the performance index which the designers seek. When the attack angle is greater than or less than the critical value, the wind wheel will work with low efficiency. This system adapted mechanical centrifugation pitch control wind wheel, which make use of heavy hammer inclined on the footstalk. When the wheel speed over the rated rotate speed it will have centrifugal moment,drive the footstalk,and make the pitch angle smaller ,attack angle bigger. when it is bigger than the critical angle of attack, the air stream on the surface of the wing will separate and bring backset and made the wing stall. The resistance will be bigger and lift force smaller. At the same time the wind wheel work with low efficiency ,the energy utilization and. rotate speed will be lower. So that it can control the speed. The prominent speciality of this system is pitch and stall doubling control. The whole system can work reliably and run smoothly.
