本文简要介绍小型多翼式前向风机试验研究结果,对三种试验风机进行对比分析,从中筛选出一种满足工艺要求的实用叶轮。这种小型风机达到了小型多翼式风机的新水平,其压力系数P=1.29,效率η=0.78。文章还对实验数据作了理论分析,就小型多翼式风机的设计提出一些有益的看法。
This article briefly introduces the experimental results of the small multi-wing forward fan, comparative analysis of the three kinds of test fan, filter out a practical impeller to meet the process requirements. This small fan has reached a new level of small multi-winged fan, the pressure coefficient P = 1.29, efficiency η = 0.78. The article also made a theoretical analysis of the experimental data, put forward some beneficial views on the design of small multi-winged fan.
