上海工业建筑设计院声学组多年来在有关单位配合协作下,对各类风机、空压机等通用设备的噪声特性及降噪技术进行了大量的调查、测试和试验研究工作,先后设计研制成T—701—6型低中压通风机消声器系列、D型罗茨风机消声器系列、F型离压风机消声器系列、K型空压机消声器系列、Z型轴流风机消声器系列及多种非标准消声器产品等.这些系列化消声器大多具有消声性能好、阻力小、结构合理、安装方便、规格齐全等特点,多年来已在许多工矿企业得到广泛应用,为大量工厂解决了风机、空压机等空气动力设备的噪声污染问题,对保护工人健康,保障居民住房的安宁、改善城市环境质量起到了积极的作用.近年来,
Over the years, the Acoustics Team of Shanghai Industrial Design Institute has carried out extensive investigations, tests and experimental studies on the noise characteristics and noise reduction technologies of all kinds of general-purpose equipment such as blowers and air compressors, with the cooperation of relevant units. T-701-6 low and medium pressure fan muffler series, D-type Roots blower muffler series, F-type off-pressure fan muffler series, K-type air compressor muffler series, Z-axial fan muffler series and a variety of non-standard Muffler products, etc. Most of these series mufflers have the characteristics of good muffler, small resistance, reasonable structure, convenient installation and complete specifications, etc. They have been widely used by many industrial and mining enterprises over the years and have solved the problems of fans, air compressors And other aerodynamic equipment noise pollution issues, to protect the health of workers, to protect the tranquility of residential buildings and improve the quality of urban environment has played a positive role.In recent years,
