摘要
本文指出了提高离心通风机性能的若干途径。在4-69№5A离心风机的研制中,将这些想法应用于气动和结构设计的改进和试验。新机与目前广泛使用的4-72№5A离心风机相比,设计点处全压效率提高6%,噪声下降4dB。
In order to improve performance of the centrifugal fan, some suggestions are presented and they have been used in design and experiment of model 4-09 № 5A centrifugal fan. Compared it with 4—72 № 5A centrifugal fan it was found stagnation pressure effieienc rised 6% and noise level is 4 dB lower.
