摘 要: 本文对某型筒形风机气动性能及噪声进行了详细的试验研究,结果表明:筒形风机气动性能曲线平坦,高效区宽,无"驼峰",在变工况下运行时不会发生"喘振"现象;比A声级曲线平坦,且比A声级噪声随运行转速升高而略有下降的趋势。 Detailed experimental studies of the aerodynamic performance and the noise characteristics of a cylindrical fanare performed in this paper.The test results show the cylindrical fan’s aerodynamic performance curve to be flat,in the highefficiency area without‘hump’,and no surge under variable working conditions.The A-weighted sound pressure level curveis flat,and it shows a decreasing tendency with increasing rotational speed.
