摘　　要：为满足某些受限工况下高压气动噪声处理需求,研制了一种适用于狭小封闭空间使用的小型高压消声器。该消声器主要采用阻性消声技术对高压用气设备排气产生的气动噪声进行降噪处理,结构上采取内外双支撑骨架设计,增强抗高压冲击能力,经过测试该消声器可承受35 MPa高压气体冲击,消声量可达到45 dBA以上。In order to meet the demand of high-pressure pneumatic noise processing under some restricted conditions,a small high-pressure muffler suitable for use in narrow enclosed space was designed.The muffler mainly adopts the resistance muffler technology to reduce the pneumatic noise generated by the exhaust of high-pressure gas equipment.The structure adopts the internal and external double support skeleton design to enhance the resistance to high-pressure impact.After testing,the muffler can withstand the impact of 35 MPa high-pressure gas,and the noise reduction can reach more than 45 dB.
