安徽水利机械厂许友成同志所试制成的水、砂喷射头,使铸件清理获得了良好效果。它消除了手工清砂造成的打击内伤,并由于喷射头射出的水雾而防止了灰尘弥漫,有效地避免了职业性的硅尘病。其结构如图:喷砂机的皮管和接头4连接,被高压气体吹出的石英砂通过喷管1射出,清除铸件砂 Anhui Water Conservancy Machinery Factory Comrade Xu Youcheng pilot made of water, sand jet head, so that the casting has been cleaned up good results. It eliminates manual blow sand caused by the fight against internal injuries, and because of the jet of water spray to prevent the dust filled, effectively avoid occupational silicon disease. Its structure is shown in the figure: The sand tube of the sand blasting machine is connected with the joint 4, the quartz sand blown out by the high-pressure gas is injected through the nozzle 1 to remove the sand of the casting sand
