▲风动凿岩机在工作时产生很大的噪声,特别是在坑下作业时噪声更大,可达100分贝左右,超过了国家最大允许标准,严重危害坑下作业工人的身体健康。将此隔膜消声环安装在目前使用的风动凿岩机消声罩内,即可将噪声强度降低30％左右,使该机噪声在任何条件下作业都低于国家允许标准。该产品采用橡胶、塑料、尼龙及其他材料制成。具有结构简单,生产成本低,易于推广,使用量 ▲ Pneumatic rock drill rig produces a lot of noise at work, especially in pit operation noise more, up to 100 decibels, exceeding the national maximum allowable standard, seriously endanger the health of workers under the pit. Installing this diaphragm muffler ring in the currently used anemometer of a pneumatic rock drill reduces the noise intensity by about 30% and makes the noise of this machine under any conditions lower than the national permissible standards. The product is made of rubber, plastic, nylon and other materials. Has a simple structure, low production costs, easy to promote, the amount used
