本文研究了国内外空气压缩机组噪声水平,指出国外微型空气压缩机组噪声级为57～62dB（A）,动力用空气压缩机组为75～80dB（A）,大型移动式空气压缩机组达85dB（A）,而国内产品一般比国外高10～15dB（A）。本文还提出消声措施及其技术要求,并指出综合考虑采用减噪措施,进一步降低空气压缩机噪声级,是空气压缩机在当前和较长一段时间内竞相努力实现的技术经济指标之一。
This paper studies the noise level of air compressors at home and abroad, pointing out that the noise level of foreign miniature air compressors is 57 ~ 62dB (A), power air compressor is 75 ~ 80dB (A), large mobile air compressors are 85dB ), While domestic products are generally 10 ~ 15dB higher than abroad (A). This paper also puts forward noise elimination measures and their technical requirements. It also points out that adopting noise reduction measures to further reduce the noise level of air compressors is one of the technical and economic indicators that air compressors strive to achieve at present and for a long time.
