我厂的三台高速风动磨头机床,使用时磨头轴承间需有一定的气膜压力和保持每分钟6～10万转的速度,气体压力在4个大气压以上,结果产生刺耳的排气气流噪声。为了消除噪声危害,我们设计制作了Ⅰ型和Ⅱ型消声器,经使用效果良好。 Ⅰ型消声器是一种阻式消声器,通过吸声结构来进行消声 I plant three high-speed pneumatic grinding head machine, the use of grinding head bearings need to have a certain film pressure and maintain the speed of 6 to 10 million revolutions per minute, the gas pressure at 4 atm or more, resulting in harsh row Air flow noise. In order to eliminate the noise damage, we designed and manufactured Type I and Type II mufflers, which have good effect. Type Ⅰ muffler is a type of muffler, through the sound absorption structure to silence
