轴流风机串联排气特性的试验研究

Experimental Study on the Ventilating Characteristics of the Axial Fans in Series

由于对风机串联特性的系统研究较少,使得在风机串联运行时参数的选择上存在着盲目性。因而,对风机串联特性的研究有着重要的实用价值。为此,进行了多种转速组合下的轴流风机串联排气性能试验,分析了单机性能、理论叠加性能和实际总排气性能间的关系,得出了轴流风机串联排气的一般规律,对风机串联时参数的选择具有一定的指导意义。

Under the condition of changing rotating speed, we made experiments of the series ventilating characteristic of the Axial Fan-the Axial Fan and analyzed the relationships among the single-machined performance, theoretical adding performance and the total ventilating performance actually. The general laws of the series characteristic of the Axial Fan-the Axial Fan were gained. It has practical value to the parameter selections of the axial fans in series.
