喷砂机是零件去锈和提高表面耐磨性的一种有效设备,因此,在机械工厂里被广泛采用。喷砂机一般由喷砂室、运转部分、喷砂系统和吸尘器等部分组成。喷砂机运转工作盘的转动多数是由电动机通过一套齿轮变速机构来带动的,但这种结构比较复杂,若采用气体吹动一个叶轮,由叶轮带动工作 Sandblasting machines are an effective tool for removing rust and increasing the wear resistance of surfaces and are therefore widely used in machine shops. Sandblasting machine is generally composed of sandblasting room, running part, sandblasting system and vacuum cleaner and other components. Most of the rotation of the sandblasting working disk is driven by a motor through a gear shifting mechanism. However, the structure is more complicated. If the impeller is driven by the gas and driven by the impeller
