摘　　要：叶片切割量是机电类风机的一个关键参数,直接关系到风机运行时的效率和稳定性,为了研究不同风叶切割量情况下的风机运行特性,采用FLUENT流体仿真分析软件,对轴流式通风机在不同叶片切割量情况下的工作特性进行分析,结果表明叶片的切割量对风机工作时的全压和效率有显著的影响,为了确保风机在常用的工作区间稳定运行,叶片切割量应保证风叶的叶顶间隙不变。Blade cutting quantity is a key parameter of electromechanical fan, which is directly related to the efficiency and stability of fan operation. In order to study the operation characteristics of fan under different blade cutting quantity, the working characteristics of axial-flow fan under different blade cutting quantity are analyzed by using fluent fluid simulation analysis software. The results showed that the amount of blade cutting had a significant impact on the total pressure and efficiency of the fan. In order to ensure the stable operation of the fan in the common working range, the amount of blade cutting should ensure that the top clearance of the fan blade remains unchanged.
