我厂弹簧装配线上有四台气动铆钉机。在排气放空时,由于压力突变,引起气体扰动,产生强烈的空气动力性噪声。影响了装配线上几十名工人的正常工作和健康,降低了工作效率。因此,必须设法消除这一设备缺陷。由于在声源中显著地减弱空气动力噪声比较困难(需要限制气流和机组运动部分的速度,造成最好的环流条件,以及减少在排气时压力的落差),所以我们采取了在排气管上装 I plant spring assembly line has four pneumatic riveting machine. When the exhaust vent, due to sudden pressure changes, causing gas disturbance, resulting in strong aerodynamic noise. Affect the normal work and health of dozens of workers on the assembly line and reduce work efficiency. Therefore, we must try to eliminate this equipment flaw. Due to the significant weakening of the aerodynamic noise in the sound source (the need to limit the speed of the airflow and the moving parts of the unit, resulting in the best circulation conditions, and reducing the pressure drop during venting) Tops
