喷砂清理是机械制造中应用极广的工序,凡锻造、铸造、热处理和表面处理的零件,都要经过喷砂来清除表面的氧化皮、粘砂、旧镀层、熔盐、銹蚀等。利用水力或压缩空气为动力,喷射弹丸或砂子来清理零件表面的各种标准型号的机械,在各个企业内已取得了极广泛的应用。这些设备虽然效率高,但制造成本亦高,不能使所有的大、中、小型企业都能普遍使用。为了满足一些中、小型企 Sand blasting is a very wide range of processes used in machinery manufacturing, where forging, casting, heat treatment and surface treatment of parts, have to go through blasting to remove the surface of the oxide, sticky sand, old coating, molten salt, rust and so on. The use of hydraulic or compressed air as the driving force, the shot pellets or sand to clean the surface of the parts of various standard models of machinery, has made a very wide range of applications in various enterprises. Although these devices are highly efficient, they also have high manufacturing costs and can not be universally used by all large, medium and small-sized enterprises. In order to meet some medium and small enterprises
