我厂铸造车间使用的两台Q3110型抛丸清理滚筒,原用高速回转的叶轮抛丸,叶片磨损快,耗量大,每天要更换一次,停台时间多。根据这种情况,车间领导、工人和技术人员三结合进行研究,将叶轮抛丸改为气体喷丸,并设计了一个铁丸喷嘴(如图), Two Q3110 type shot blasting cleaning drums used in our foundry’s casting workshop are used. The original high-speed rotary impeller shot blasting, the blades wear fast, consume a large amount of oil, and have to be replaced once a day. According to this situation, workshop leaders, workers and technicians combined three studies, the impeller shot blasting into gas shot peening, and the design of a shot iron nozzle (pictured)
