摘要:为分析不同接头的三通的冲蚀磨损情况,以某公司生产的4种不同接口形状的液压三通管接头为对象,利用有限元分析软件对4种型号的三通管接头模型进行冲蚀分析,对比了不同型号的三通管接头的冲蚀磨损影响,得到最大冲蚀率最小情况下的一种,为后续三通管接头的选用研究提供参考价值。结果表明,其中D型三通管接头的最大冲蚀率相较于其他三种型号的较高,A、C、H型这3种三通管接头的最大冲蚀率无较大区别,其中H型的最大冲蚀率较低,达3.51 × 10-3 kg·m-2·s-1。

Abstract:In order to analyze the erosion and wear of the tee of different joints, four types of hydraulic tee joints with different interface shapes produced by a certain company are used as the object, and the four types of tee joint models are eroded using finite element analysis software. Analysis and comparison of the erosion and wear effects of different types of three-way pipe joints are obtained, and the maximum erosion rate is the smallest, which provides reference value for the subsequent selection and research of three-way pipe joints. The results show that the maximum erosion rate of the D-type tee joint is higher than that of the other three types. The maximum erosion rate of thethree-way pipe joints of A, C, and H-type is not much different. Among them, the maximum erosion rate of the model of H-type is relatively low, reaching 3.51 × 10-3 kg·m-2·s-1.

三通接头在人们生活中应用广泛,在各个行业如石油化工、海洋、机械工程等都有涉及,主要用在油井固井、压裂施工作业的管汇上,是各种液压管路系统重要连接部分[1-2]。在工作过程中,由于液体压力和流速的影响,三通接头内部经常受到严重的冲蚀磨损影响[3-4],且随着液体压力变大,冲蚀磨损现象愈发严重,因此对三通管接头的性能要求也变高。冲蚀磨损是油气行业不可避免的退化过程,夹带的固体颗粒会撞击管道内表面[5-7],造成机械磨损,最终导致设备失效,造成经济损失。因此,研究得到最小冲蚀率的一种接口形状的三通管接头,增大装置寿命,对后续的研究有重要意义,并促进采油事业的发展。
