采用不同风管试验装置的通风机性能试验研究

摘要

通过对几台通风机分别采用不同风管试验装置进行性能试验，将其试验结果进行了比对，发现不同的试验装置对测得的风机性能曲线存在一定的差异，并对差异结果进行了分析，得到初步结论。%Performance tests of several sets of fans which were carried on with different duct test devices were compared. It was found that there is some deviations among the obtained performance curves with different duct test devices and the differences were analyzed and preliminary conclusions were drawn in this paper.
