前言 ·風車調速机构的作用,是使風車在風速經常发生变化的条件下运行时,仍有稳定的轉速和輸出功率。常用的几种調速机构中以使風輪偏側的調速机构为最簡单,它的制作很容易,特別适合于当前在我国广大农村推行的簡易風車上应用,这种机构的工作原理如图1所示。在不同的風速下,風輪应与風向成不同的偏角,以保持其轉速与功率的稳定,此时風車調速彈簧K的恢复力P_K对風車机头迴轉中心的力矩(以下簡称弹簧力矩),同使風輪偏側的
Preface · The function of the speed regulating mechanism of the windmill is to keep the speed and output power of the windmill steady when the wind speed is constantly changing. Several commonly used speed governing mechanism in order to make the rotor side of the speed governing mechanism is the simplest, its production is very easy, especially for the current implementation of simple windmills in rural areas of our country the application of the principle of this body As shown in Figure 1. At different wind speeds, the wind wheel should have a different declination angle with the wind direction in order to maintain the stability of its speed and power. At this moment, the restoring force P_K of the wind turbine speed control spring K exerts a great influence on the torque of the wind turbine head rotation center Torque), with the wind wheel side
