我厂机械加工车间使用的 气动夹具和气动尾架,均用手 动气阀操纵。当这些气动件运 动时,气阀会产生刺耳的排气 气流噪声,影响工人的身体健 康。经测定,在距排气口0.5 米处(相当于操作者所在位 置),排气噪声达110分贝(A) 左右。 1981年我厂在治理噪声的 工作中,自行设计了一种排 I plant mechanical processing plant used pneumatic clamp and pneumatic tailstock, are manually operated valve. When these pneumatic components move, the air valve will produce harsh exhaust airflow noise, affecting the health of workers. It has been determined that at a distance of 0.5 m from the exhaust port (corresponding to the operator’s location), the exhaust noise reaches about 110 decibels (A). In 1981 I plant in the management of noise work, designed a row of their own
