长征系列液体火箭发动机导管锉修技术

Pipe filing-repairing technology for Long March Series liquid rocket engine

导管锉修是发动机装配工作中一项重要操作技能,根据液体火箭发动机的装配特点,从导管锉修流程中导管比试、导管锯切和导管锉修3个环节进行论述,深入剖析了发动机导管锉修技术的关键和难点,得出了导管锉修技术方法。从实际装配经验中归纳总结了4条导管的比试准则,归纳总结了6条影响导管锯切位置的关键影响因素,并详细说明了导管锉修应满足的5项要求以及各项控制参数。

The pipe filing-repairing is one of the important skills in engine assembly. Based on the assembly features of liquid rocket engines, the keys and difficulties of pipe filing-repairing technology were discussed in terms of three steps： pipe match check, pipe cutting and pipe filing-repairing. Ac- cording to actual assembly experience, the four principles of pipe match check, six key factors influ- encing the position of pipe cutting, and five requirements and corresponding controlling parameters were summed up. The pipe filing-repairing technology was realized successfully.
