摘　　要：磨料水射流切割技术能够满足油气储运设备设施应急抢修切割的需求。通过切割试验研究了便携式磨料水射流切割系统对管线钢的切割特性,得到压力、靶距和横移速度对切割深度的影响关系,提出了切割深度预测模型。结果表明:切割深度与切割压力成正比,与靶距和横移速度成反比。切割深度模型对切割结果预测的最大误差为15.04%,最小误差为0.87%,平均误差为5.98%,表明切割深度模型在一定参数范围内能够有效指导切割工艺的制定。Abrasive water jet cutting technology can meet the requirements of emergency repair for oil and gas storage and transportation facilities. Through cutting experiments which were carried out on pipeline steel by portable abrasive water jet cutting system to research the cutting characteristic,the law for impacts of pressure,standoff distance and traverse rate on cutting depth was obtained,and then a cutting depth prediction model was put forward. The results show that the cutting depth is proportional to the pressure and inversely proportional to the standoff distance and the traverse rate. The maximum error of prediction result of the cutting depth by the cutting depth model is 15. 04%,the minimum error is 0. 87%,and the average error is 5. 98%,which shows that the cutting depth model can effectively guide the cutting process establishment in a certain parameter range.
