一、简况我厂表壳车间噪声很大,环境噪声有96分贝(A).其中一台160吨冷挤压床噪声高达115分贝(A).在远离100米处仍听到尖锐的“咔啮!咔啮!”声.在该台冷挤压床工作时,其它人不愿在附近停留,维修工人只得远远逃避.115分贝(A)强噪声给冷挤压生产和工人的健康带来困难和危害.为降低噪声,保护工人健康,我们把二组联合器(刹车片)用隔声罩封闭起来,在排气口装上微孔消声器,取得了较好效果(见简图).
First, the briefing I plant noise is large workshop workshop, the environment noise is 96 decibels (A) .One of 160 tons of cold extrusion bed noise up to 115 decibels (A) .At a distance of 100 meters still hear sharp "carbazole When the cold extrusion bed was working, others were reluctant to stay in the vicinity and maintenance workers had to flee far .115 dB (A) Strong noise for cold extrusion and workers’ health belt To reduce the noise and protect the health of workers, we sealed the two sets of brakes (brakes) with a soundproof cover and installed the microporous muffler on the exhaust port to achieve good results (see diagram) .
