【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。更多还原

【Abstract】 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.更多还原
