摘要
在查阅了国内所有关于轴流通风机扩散筒效率的论述和测量数据的基础上,详细推导了轴流通风机扩散筒效率、损失和静压升系数等公式,并对一台按当量直径设计的16号轴流通风机的扩散筒和扩散塔的效率进行了测量,结果表明:扩散筒的效率较文献推荐值低。
On the basis of checking all the data about the discussion and measurement for the efficiency of the diffuser tube for axial-flow fan in China, it deduces in detail the formula of the efficiency, loss and static pressure rise coefficients of diffuser tube for the axial-flow fan, and to measure the efficiency of diffuser tube and diffuser tower of No16 axial-flow fan which was designed as equivalent diameter. The result shows: The efficiency of the diffuser tube is lower than the recommended value form the literature.
