【摘要】 本文采用R.J.Templin的方法,对以自然风为动力的立轴型排风机,进行了理论计算与分析。结果表明,风机的输出功率与转数、风速成正比。增大风机半径、高度,功率也会增大。单个叶片在θ=90°,270°位置时输出功率最大;在θ=0°,180°,360°位置时输出功率最小。更多还原

【Abstract】 Based on the R.J.Templin method,a theoretical calculation and analysis for vertical shaft blower drove by the natural wind is presented in this paper.The results show that the output power of the blower has direct ratio with the revolution and wind velocity and it is also enhanced with the increase of the radius and the altitude of the blower.At the positionθ=90°.270°,a single vane obtains the maximum output power,however,at the positionθ=θ°,180°,360°,it gets minimum output power.更多还原
