北京第一通用机械厂五车间是个空气压缩机组装车间,面积很大,工种较多。为确保压缩机管道和辅机设备清洁畅通,压缩机组装后均在车间内进行中间吹除试验,即启动压缩机将一级气缸压缩到 3公斤/厘米～2的空气直接排至大气,使一级气缸通道及中间冷却器中的铁屑及油污等吹出。由于吹除时气流噪声很大,车间噪声A声级在100分贝以上,严重危害工人健康。因此,急待解决降低噪声问题,非常需要体积小、重量轻、装拆方便的消声器。北京第一通用机械厂五车间实行工人、技术人员和领导干部三结合,根据中国科学院物理研究
Beijing First General Machinery Plant five workshops is an air compressor assembly shop, a large area, more types of work. In order to ensure the compressor pipeline and auxiliary equipment clean and smooth, the compressor assembly are in the workshop after the middle blow-off test, which started the compressor will be a cylinder compressed to 3 kg / cm ~ 2 of the air directly to the atmosphere, A class of cylinder channels and intercooler in the iron and oil and other blow out. As blowing air blowing noise is very large, workshop noise A sound level of 100 dB or more, seriously endangering the health of workers. Therefore, the urgent need to solve the problem of reducing noise, very small size, light weight, easy assembly and disassembly muffler. Beijing First General Machinery Plant five workshops implement the three workers, technicians and leading cadres, according to the Chinese Academy of Sciences
