为消除L型空压机进气口气流噪声,上海机电设计研究院和余姚通用机器厂共同研制成功与L型空压机配套使用的YXL10A型及YXL20A型低频抗性消声器,并于去年底鉴定通过,经鉴定,该消声器的消声特性、空气动力性能良好,阻损小。空压机配套消声器后,排气量基本不变,比功率增加小于1%,可 In order to eliminate the airflow noise of the air inlet of L-type air compressor, Shanghai Mechanical & Electrical Design Institute and Yuyao Tongji Machinery Factory co-developed YXL10A and YXL20A low-frequency resistant muffler which are used together with L-type air compressor and were identified at the end of last year Passed, identified, the muffler muffler features aerodynamic performance good, small resistance loss. Air compressor supporting muffler, the displacement of the same basic, than the power increase of less than 1%, can be
