用于清理铸件浇冒口及表面修整的S150型风动砂轮机,在我厂清整车间广泛地使用。其动力源为5～6kgf/cm~2的压缩空气,进入机内气缸,推动叶片,使主轴旋转,从而带动砂轮工作。由于其转速在5000rpm以上,在排气口产生一种强烈的啸叫噪声。当砂轮机工作时,直接危害到操作工人的身心健康,如连续工作几小时,使大脑极易疲劳,从而也降低工作效率。为控制风动砂轮的噪声,我们设计试制出FW型风动砂轮微孔消声器,经试用,获得了较好的效果。
S150-type wind-driven grinder used to clean the pouring riser and surface finishing of castings is widely used in the cleaning workshop of our factory. The power source for the 5 ~ 6kgf / cm ~ 2 compressed air into the machine cylinder, promote the leaves, the spindle rotation, which led to the work of the wheel. Due to its speed above 5000rpm, a strong whistling noise is generated at the exhaust port. When the grinder work, directly endanger the physical and mental health of workers, such as hours of continuous work, so that the brain is very easy to fatigue, which also reduces work efficiency. In order to control the noise of the wind-driven grinding wheel, we designed and manufactured the FW-type wind driven grinding wheel microporous muffler. After trial use, we achieved good results.
