摘要
高压磨料射流切割作为新兴的切割技术高效、环保优势明显,该技术在国内石油工业的应用尚处于起步阶段。为满足油田大尺寸管柱结构物外切割作业需求,基于SOLIDWORKS软件设计自爬行式高压磨料射流外切割执行机构,建立执行机构运动过程受力理论模型,计算执行机构所需吸附力,并利用ABAQUS软件和ADAMS软件进行轨道极限弯曲性能和执行机构动力学特性分析。结果表明,执行机构在不同工况条件下运动平稳,性能可靠,适用于切割直径大于1.5 m的管柱结构物,执行机构现场切割管柱试验取得成功。
High pressure abrasive water jet cutting, as a new cutting technology with obvious advan-tages of high efficiency and environmental protection, is still in its early phase in Chinese oil industry. To meet the demand of external cutting operations for large-sized pipe structures in oilfields,the exter-nal cutting actuator for auto-crawling high pressure abrasive jet is designed by the software SOLID-WORKS.The theoretically mechanical model of the motor process of the actuator is established to cal-culate the absorbability for the actuator.Meanwhile,software ABAQUS and ADAMS are used to ana-lyze the limiting bending performance of the track and dynamic characteristics of the actuator. The re-sults show that the actuator with steady and reliable moving performance is suitable for pipe structures whose cutting diameters are more than 1.5 m. The field test of cutting pipes by the actuator has achieved success.
