输油泵出口管线流固耦合振动分析及减振措施
|
摘要
输油泵管道是油田输油生产的关键设备之一,其能否正常运行,直接关系到整个输油装置的运转。基于ANSYS软件建立输油泵出口管道有限元模型,首先,对输油泵出口管道进行模态分析,得到管道模型的固有频率和各阶振型;其次,开展热-应力耦合分析计算,得到出口管线的应力和应变情况;再次,进行双向流固耦合计算,分析流体与管道的互相影响,得到不同时刻管道的周期性振动频率;最后,根据数值计算结果和现场测试情况,提出不同的减振措施。通过对改进前后管道的振动情况进行对比,发现输油泵出口管道的振动情况有了很大的改善,表明该方法能够有效减小管道振动,可供类似工程借鉴参考。
Oil pump pipeline is one of the key equipments in oil production. Whether it can run normally is related to the operation of the whole device directly. The finite element model of the export pipeline of oil pump is established based on ANSYS. Firstly,modal analysis is carried out on the outlet pipeline of the oil pump to get the natural frequency and different order mode of vibration of the pipeline model. Secondly,the thermal-stress coupling analysis is carried out to obtain the stress and strain of the outlet pipeline. Thirdly,the bi-directional fluid-structure coupling calculation is carried out in this paper,and the interaction between fluid and pipeline is analyzed to obtain the periodic vibration frequency of pipeline at different times. At last,different vibration reduction measures are proposed according to the results of numerical calculation and field test. By comparing the vibration of the pipeline before and after the improvement,it is pointed out that the vibration of the outlet pipeline of the oil pump has been greatly improved,which shows that the method can effectively reduce the vibration of the pipeline and provide reference for similar projects.
