由中国船舶工业总公司第九设计研究院设计、江苏宜兴分水噪声控制设备厂制造、安装于上海吸尘器厂和上海浦江发动机厂的自动冲床隔声罩,于1986年11月27～28日在沪通过了评审。会议由上海市普陀区科协主持,参加评审会的有高等院校、科研、设计、环保、监测、生产、使用等单位,共70名代表。高速自动冲床噪声一般为100～105dB(A)。目前设计制造的组装式自动冲床隔声罩主要用于进口的85吨和125吨高速自动冲床的隔声降噪,可使自动冲床的噪声降至80～85dB(A)。评审会一致
By the Ninth China Shipbuilding Industry Corporation Design Institute of Design, Jiangsu Yixing watershed noise control equipment manufacturing plant, installed in Shanghai Vacuum Cleaner Factory and Shanghai Pujiang Engine Factory automatic punch noise enclosures, in November 1986 27-28 Shanghai passed the review. The meeting was presided over by Putuo District Association for Science and Technology of Shanghai and attended by 70 institutes of higher learning, scientific research, design, environmental protection, monitoring, production and use. High-speed automatic press noise is generally 100 ~ 105dB (A). At present, the design and manufacture of the assembly of automatic punch press hood is mainly used for imported noise of 85 tons and 125 tons of high-speed automatic punch noise, automatic punch press noise down to 80 ~ 85dB (A). The review will be the same
