摘要
为了研究集成式高温不压井修井机液压控制系统的稳定性和可靠性,针对修井机液压控制系统中的液压缸结构,对卡瓦夹紧液压缸进行优化分析。通过修井设备的工作原理,根据其特定系统功能及工艺要求选取液压缸,同时,对选取的液压缸中活塞杆进行强度校核。然后利用液压缸腔内液体的压力与流量关系建立数学模型,并且结合数字PID控制算法理论,运用MATLAB软件对液压缸的数学模型进行优化仿真,并且,运用Simulink功能,仿真液压缸启动时速度与平稳运作时速度变化曲线,最后,得到数据分析设备液压控制功能的稳定性与可靠性。
In order to study stability and reliability for the hydraulic control system of integrated hyper-thermal snubbing operation,aimed to hydraulic cylinder structure of snubbing operation＇s hydraulic control system,so as to slip clamping hydraulic cylinder for optimize analysis. Through the working principle of workover equipment,selected a hydraulic cylinder according to it＇s specific system function and process requirements,meanwhile,carry out intensity check for the piston rod of the hydraulic cylinder,then employed chamber fluid pressure and flow relationship of the hydraulic cylinder to built a mathematical model,and combined with digital PID control algorithm theory,MATLAB is used to carry out optimize simulation for the mathematical model of the hydraulic cylinder,also used function of Simulink to simulated the hydraulic cylinder starting speed and smooth operation speed change curve,finally,got data that analyzed the stability and reliability of the hydraulic control function.
