1968年我们制成一台小型加压式喷砂机,它是利用加压式喷丸器的道理,将加压缸布置在机身底部而成(见图)。其工作台可以自由回转并能拉出三分之一,这样,大一些的工件就可用天车吊装。所有的砂粒都在机壳内循环,太细的粉尘由风机抽出,劳动条件好,可不戴口罩工作。 In 1968 we made a small pressurized sandblasting machine, which is the use of pressurized shot blasting machine, the pressure cylinder is arranged in the bottom of the fuselage made of (see photo). Its table can be freely swiveled and can pull out one-third, so that larger workpieces can be hoisted by crane. All the sand particles are circulated in the casing, too fine dust is drawn by the fan, working conditions are good, do not wear a mask work.
