摘　　要：提出了设计对旋式轴流通风机的基本设计思路。针对设计和生产中出现的诸如效率太低、噪声偏高、结构振动、叶片断裂、烧毁电机等问题，重点讨论了两级叶轮之间的负载分配和相互干扰等概念和现象，并作出适当分析，以有助于读者提高设计水平。The basic design thinking of counter-rotating axial fan is put forward in this paper.Against the problems such as low efficiency,high noise vibrating structure,blade braking,motor burn out etc.occured in designing & producing,The concept & phenomenon of load distribution & interference each other between two impellers are mainly discussed and proper analysis has been done in order to help reader in raising their design capabilities.
