我厂是以生产抗生素为主的制药厂,拥有一定数量的往复活塞式压缩机,为了降低气流脉动对管道振动及周围环境的不利影响,采用孔板进行减振与消声,收到了明显的效果。 一、我厂庆大霉素车间空压机班有L型40m～3空压机四台并联运行。长期以来,由于进气系统中很强的气流脉动,导致砖砌混凝士结构进气地道及管道连接部位产生松动和破裂;周围建筑物振动,特别是门窗玻璃晃动历害,响声大。脉动的气流噪声也给毗邻的其他作业班组,如冷冻、电工等造成很大的困扰,部分家属区职工住户也不同程度受其干扰。
I plant is the production of antibiotic-based pharmaceutical factory, has a certain number of reciprocating piston compressor, in order to reduce the pulsation of air flow on the pipe and the adverse impact on the surrounding environment, the use of orifice damping and muffling, received a clear effect. First, our factory gentamicin workshop air compressor class L-40m ~ 3 air compressor four parallel operation. For a long time, due to the strong air flow pulsation in the intake system, cracks and cracks were generated in the tunnels and the pipe joints of the brick-concrete structure. Vibrations around the buildings, especially the sliding of glass doors and windows, were loud and loud. The pulsating airflow noise also caused great troubles to other adjacent working groups, such as freezing and electricians. Some households and their families also interfered with their work to varying degrees.
