发动机导管在滑油、漏油、放油、起动、状态操纵等系统中,起着与人体血管一样极为重要的作用。因此,导管制造工艺与发动机其它零件加工一样,有一套严密完整的工艺。导管在制造中的主要工艺步骤有;外表磨光和探伤检查、弯曲、钻孔、装配和焊接、x光检查、热表处理、校正、液压试验等。本文针对以上加工工艺的特点、生产中的改进,以及所遇到的主要问题和解决的措施等进行了叙述。
Engine duct in the oil, oil spills, put oil, start, state control system, plays the same with human blood vessels is extremely important role. Therefore, the catheter manufacturing process and other parts of the engine processing, there is a rigorous and complete process. Conduit in the manufacture of the main process steps are; external polishing and inspection, bending, drilling, assembly and welding, x-ray inspection, heat treatment, calibration, hydraulic test. This article describes the characteristics of the above process, the improvement in the production, the main problems encountered and the measures to be taken.
