介绍用于对航空发动机部分进行X射线检测的微焦点棒阳极射线管,这种棒阳极射线管要求其可以在高强度的X射线下进行长时间的曝光拍摄,应具有很好的稳定性和持久性,故需要采用新的结构设计和冷却系统。探讨了减少射线管使用中所产生热量和改进冷却系统等问题,提出将密封胶圈纳入冷却循环的方法。解决了这些重大技术问题后,组装出紧凑耐用的棒阳极射线管,应用到了飞机发动机检测中,降低了设备的故障率,优化了发动机制造厂的X射线检测过程。 Introducing a micro-focus rod anode ray tube for x-ray detection of the aeroengine section, which requires its exposure to long exposures under high-intensity x-rays, with good stability and Persistence, it requires the use of new structural design and cooling system. The problems of reducing the heat generated in the tube and improving the cooling system are discussed. A method of incorporating the sealant into the cooling cycle is proposed. Solve these major technical problems, the assembly of a compact and durable rod anode ray tube, used in aircraft engine testing, reducing the failure rate of equipment, optimizing the engine manufacturer’s X-ray detection process.
