• Abstract: The application of high quality pipe inner wall sand-blasting especially suction sand-blasting to the inner wall of long pipe is a difficult problem in surface engineering field. It needs to take the lead in solving the two technical bottlenecks of high efficiency sand-blasting and multi-runner rotary seal. The wind tunnel sand- blasting gun improves the efficiency of suction sand-blasting, the double-flow two- phase flow rotary sealing joint solves the problem of gas and material supply in rotation, and the introduction of scanning mechanism finally realizes the engineering significance of the automatic application of uniform and efficient sand-blasting on the inner wall of long pipe. It provides advanced surface engineering equipment with convenience, environmental protection, high quality and automation for the pretreatment process of pipe inner wall painting, thermal spraying, electroplating and vacuum coating in narrow space. 高质量管内壁喷砂特别是吸入式喷砂应用于长管内壁预先处理是长期 困扰表面工程界的难题。它需要率先解决高效率喷砂和多流道旋转密封两个技 术瓶颈。风洞式喷砂枪提高了吸入式喷砂效率，双流道两相流旋转密封接头解 决了旋转中的供气供料问题，引入扫描机构最终实现了工程意义的长管内壁均 匀高效喷砂自动化应用。为狭窄空间的管内壁涂装、热喷涂、电镀、真空镀膜 等预处理工序的广大需求提供了具备便捷性、环保性、高质量和自动化的先进 表面工程设备。
