摘要
为改善带压作业开关密封系统的性能和提高工作寿命,提出了由橡胶和聚合物材料组合的开关柔性密封结构,该密封由2个半环组成。建立了橡胶和聚合物材料组合密封模型,利用有限元方法对组合密封胶芯进行了非线性计算,胶芯整体受力和变形状态满足设计要求,该方法可用于开关柔性密封的优化设计。利用带压作业试验台和油田现场带压作业设备,进行了密封胶芯磨损试验,试验结果证明,组合密封胶芯在水润滑状态下的工作寿命得到很大提高。
For advancing the seal performance to long life time, a new on-off flexible seal composed of rubber and polymer that has two symmetric half-circle sealing component was put forward.The seal module consisted of rubber elastomer and polymer materials was set up, the nonlinear equation was computed by using the finite element method.The simulation results show that the mechanics behavior and deformation between the rubber and the polymer materials of the on-off flexible seal satisfy the design requirement,it p...
