摘要
以“FPSO+CTV+VLCC”三浮体外输原油作业的管道旋转接头高参数密封系统为研究对象,针对泛塞封蓄能密封装置这一典型结构,建立综合考虑密封装置静摩擦时微间隙介质流体力学行为、密封件及管端宏观固体力学行为、表面微凸体瞬态接触力学行为等多物理过程耦合的非线性密封数值仿真模型,以泄漏量、接触压力、接触区域宽度等作为目标参数,通过有限元仿真和数值计算方法,研究分析在静密封条件下三种不同结构的泛塞封在不同介质压力和不同介质下的密封性能,并选出了其中的较优结构。
Taking the"FPSO+CTV+VLCC"three-floating high-parameter sealing system for crude oil transportation externally as the research object,aiming at the typical sealing structure of the pan-plug seal,the hydrodynamic behavior of the micro-gap medium and the sealing parts were established considering the static friction of the sealing device.Nonlinear sealing numerical simulation model coupled with multiple physical processes such as the macroscopic solid mechanical behavior of the pipe end,the transient contact mechanical behavior of the surface asperity,etc.The sealing performance of three different structures of plugging seals under different media pressures and media under static sealing conditions is studied and analyzed,and the optimal structure is selected.
