摘要
通过对轴流式通风机高效区分布特性的研究,找出了在转数和轮毂比一定的条件下其高效区域分布的规律,从而发现了通风机运行工况发生变化时高效工况点的情况,为通风机的运行平稳、安全可靠、工作效率的提高提供了理论依据。
By research of axial- flow fan characteristic distribution in high efficiency operating range, a distribution rule is discovered on the definite rotating speed and hub ratio condition, consequently condition of high efficiency operating point is easy to be found when axial - flow fan operating course is changed. The rule is the theory for axial- flow fan to increase steady work, reliable safety and the work efficiency.
