基于高压水射流的燃气管道带压智能切割机械的研制

Research on Intelligent Cutting Equipment of Gas Pipe Based on High-pressure Water Efflux

燃气输送管道经常需要在不断气运行情况下安装分支管道,其与主管道相贯部分的切割必须防火、安全、不漏气。基于高压水射流的燃气管道带压智能切割机械采用添加磨料的高压水射流作为切割方法,能满足由不同管径、不同相交角度、非标准圆管相交而成的非标准相贯线在密封环境中的自动切割,并能自动取出废料。本文介绍了该机械的总体结构、智能控制方案、运动执行机构及密封结构。使用结果表明相贯部分切割准确,且切割过程高效、安全,完全符合使用要求。

A new branch pipe has to be equipped when the pipe is transporting gas. Cutting process of intersected part with branch pipe in main pipe must be safety, quick and gas were not leaked. Intelligent cutting equipment adopted high-pressure water efflux with abrasive as cutting method and can automatically cut standard and non-standard intersecting lines formed by intersecting of different diameter pipe in different angle and non circle pipes in sealed pipe, and take off cutted material. General structure, intelligent control scheme, movement mechanical and sealing device were introduced. The results of application show that intersecting line is cutted accurately and the machine meets the requires of user.
