【摘要】 本文以不压井修井作业机械化装置为研究对象,根据其系统方案、整机的工作原理以及其作业流程的要求,提出了整机液压系统的设计要求,并对其各个执行机构的运动以及负载进行工况分析。在此基础上,根据计算及相关设计要求经验,确定主机液压系统参数、拟定液压系统图并选定各液压元件、油箱组件以及液压泵组,并合理设计其安装结构、排布系统管路,完成不压井修井作业机的样机液压泵站及控制台的设计。针对不压井作业机液压系统动态性能要求研究其液压系统的建模理论,应用解析法进行建模,对大臂起升、扶正手液压系统和井架起升系统进行分析并将其简化为阀控非对称缸和定量泵—溢流阀等液压单元,建立其数学模型为仿真试验奠定理论基础。基于AMESim软件搭建大臂起升系统、扶正手系统和井架起升系统的仿真模型并进行变参数仿真试验。对试验结果进行分析,从而掌握液压系统的动态特性及系统参数随时间的变化情况,并为系统的优化设计提供合理化建议,为实际液压系统的搭建提供了理论支持。更多还原

【Abstract】 Studying on the mechanized snubbing workover equipment, this paper proposed thedesigned requirements of its hydraulic system based on the system project, the operatingprinciple and the workflow, also carried out the working conditions analysis of its executivemechanism load and movement. On the basis of all above, according to the calculation and therelated designed experience of this hydraulic system, this paper accomplished calculating theparameters and sketching up the hydraulic system diagram of its hydraulic system, alsoaccomplished selecting the components of the hydraulic power pack and hydraulic pumpgroups and layouting the rational system pipeline, in the end finished designing the hydraulicpump station structures of the mechanized snubbing workover equipment .On the basis of the theoretical research of the snubbing workover hydraulic systemdynamic characteristics, this paper built the mathematical models of the big arm system, theaided manipulator system and the derrick system through the analytical modeling method, andsimplified them as Hvalve controlled asymmetric cylinderHand quantitative pump - relief valveand other hydraulic units, it used for the simulation as the theoretical foundation.The simulation models of the big arm system, the aided manipulator system and thederrick system were built through the AMESim software to simulate by setting up theexperiment parameters. The test results were analyzed in order to master the dynamiccharacteristics of hydraulic systems and system parameters changes over time and proposerational suggestion for the hydraulic system optimal design, The curve also provides atheoretical reference for the actual structures of the hydraulic system.更多还原
