摘要:

为了减少某些特殊工况下，清管器和检测器皮碗在清管和检测过程中产生的皮碗偏磨现象。深入分析了导致皮碗出现偏磨的原因，提出一种适用于直径355.6mm油气管道的复合耐磨皮碗结构设计方案。利用有限元模拟仿真分析方法验证了复合耐磨皮碗结构在不同管道壁厚下的适应能力和密封性能。结果表明：复合皮碗结构与不同壁厚管道的接触过程中，在保证固有密封性能的条件下，皮碗外边缘上的万向滚珠可以有效减少皮碗唇边与管壁之间的接触面积，分担皮碗唇边所受的正压力和接触应力。说明该复合耐磨皮碗结构设计方案具有可行性，可以有效减缓皮碗唇边磨损，减少皮碗偏磨现象的产生。该复合耐磨皮碗结构设计和密封性能的分析验证，对于丰富中国清管器和检测器用皮碗设计理念，完善清管器和检测器结构设计具有重要意义。（图7，表3，参21）

Abstract:

In order to reduce the partial abrasion of the cup of pig and detector in pigging and detection under some special conditions, the causes for partial abrasion of cup were analyzed in depth, a structural design scheme of composite wear-resistant cup for oil and gas pipeline with diameter of 355.6 mm was proposed, and the adaptability and sealing performance of the composite wear-resistant cup in pipeline with different wall thickness was verified by the finite element simulation analysis. The analysis results show that the universal ball on the outer edge of the cup can effectively reduce the contact area between the cup lip and the pipe wall, and share the positive pressure and contact stress on the cup lip under the premise of guaranteeing its inherent sealing performance during the contact between the composite cup structure and the pipeline with different wall thickness, which shows that the structural design of the composite wear-resistant cup is rational and feasible to certain extent, capable of effectively reducing the wear of the cup lip and the partial wear of the cup. The structural design and sealing performance analysis verification of the composite wear-resistant cup are of important practical significance to enrich the domestic design concept of cup for pig and detector and to improve the structural design of pig and detector.
