一、前言我厂空压机房担负全厂工业用动力风和仪表动力用风,80年扩建前有5 L-40/8型2台,4L-20/8型2台,3L-10/8型1台,80年扩建后,增加5L-40/8型4台,分别布置于8.5×21和8.5×25米的厂房内,压缩机的吸气口(滤清器)除3L-10/8型安装在室内外,其余均安装在室外北侧(即~#1蒸馏一侧)钢架上,由于吸气口脉动低频噪声与蒸馏空冷低频噪声和厂房窗户、墙壁
I. INTRODUCTION The air compressor room of our factory takes the power of wind power and instrumentation of the entire factory for industrial use. There are 2 sets of 5 L-40/8 type, 2 sets of 4L-20/8 type and 3L-10 / 8 type 1 Taiwan, 80 years after the expansion, an increase of 5L-40/8 type 4, were placed in 8.5 × 21 and 8.5 × 25 m of the plant, the compressor suction port (filter) in addition to 3L-10 / 8 installed indoors and outdoors, the rest are installed in the outdoor northern (ie ~ # 1 distillation side) of the steel frame, due to the pulsation of the inlet low frequency noise and distillation air-cooled low-frequency noise and plant windows, walls
