摘要
双层上消音器已经成为压缩机降噪的常用方案,目前该消音器的外层排气方式一般采用轴颈排气。本文目的是探究一种双层消音器的内层隔板结构,其有最优降噪效果、且能保证压缩机性能。针对两种因素来研究其对压缩机噪音与性能的影响:不同隔板在外层内部总高的占比,内层隔板不同开孔方式。实验最终确定最优降噪方案:内层隔板高度为内部总高一半,开孔位置是在逆时针数上法兰排气孔所在瓣的邻瓣。此外,兼顾性能与降噪的隔板高度方案为:内层隔板高度为内部总高0.3倍。
Double-deck silencer have become a common solution for noise reduction of compressor.At present,it is a common solution that the exhaust is from central hole of the outer-layer silencer.The purpose of this article is to explore a structure of the inner baffle for the optimal noise reduction effect and maintain performance.The influence of two factors on the noise and performance of compressor is studied,which is the ratio of different clapboard in the total height of outer layer inside and different trepanning means in inner clapboard.Optimizing denoise case by the experiment was finally determined.The height of clapboard is the half of the total height of outer layer.And the opening position is located the adjacent petal of exhaust hole located in the above-flange.In addition,it can maintain performance and noise reduction that the height of the inner baffle is 0.3 times the total height.
