分析了地铁风机的工作特点及传统反风技术的缺陷,结合地铁风机的结构特征提出了从结构设计入手解决反风问题的方法,并给出了相应的结构方案,从而使得地铁风机在正、反风时都可在最佳效率状态下工作,节能效果显著;该装置操作简便,结构紧凑、合理,占地面积小,特别适用于城市地铁建设,也适用于矿井等需要反风的场合。
Based on the analysis of the working characteristics of subway fans and the drawbacks of the traditional anti-wind technology, the method of resolving the anti-wind problems from structural design is proposed based on the structural features of the metro fan. Corresponding structural solutions are given, It can work under the best efficiency under the wind and anti-wind, and has obvious energy-saving effect. The device has the advantages of simple operation, compact structure, reasonable occupation and small area and is especially suitable for the construction of urban metro and also for occasions requiring anti-wind such as mines.
