摘要
针对目前国内石油化工企业在更换石油运输蒸汽伴热管道时,因采用人力作业而面临高空作业风险、效率低、成本高以及作业空间狭窄等问题,提出一种高效能自动化拔管机液压控制系统,该系统集夹紧、顶伸和剪断功能于一体。通过利用差动连接的液压控制系统,该系统能够根据顶伸缸外负载大小自适应调节顶伸缸活塞杆运动速度。基于机电液耦合建模理论,在AMESim环境中通过液压系统机制分析、控制策略架构设计和核心元件参数协同优化,构建拔管控制系统联合仿真模型,并开展拔管典型工况下的动态特性验证与性能评估。结果表明:该液压系统满足拔管多功能一体化要求,顶伸液压缸具有负载自适应功能。
In view of the problems faced by domestic petrochemical enterprises in the replacement of petroleum transportation steam tracing pipelines,such as the risk of high-altitude operation,low efficiency,high cost and narrow working space,a high energy efficiency automatic pipe pulling machine hydraulic control system was proposed,which integrated clamping,jacking and cutting functions.By using the hydraulic control system of differential connection,it could adaptively adjust the movement speed of the piston rod of the jacking cylinder according to the external load of the jacking cylinder.Based on the theory of electro-mechanical-hydraulic coupling modeling,a multidisciplinary co-simulation model of the pipe pulling control system was constructed in the AMESim environment through hydraulic system mechanism analysis,control strategy architecture design,and collaborative optimization of core component parameters.Dynamic characteristic validation and performance evaluation were conducted under pipe pulling typical operating conditions.The results show that the hydraulic system can meet the requirements of multi-functional integration,and the jacking cylinder has the function of load adaptation.
