流体诱发离心式动力输气管道振动分类及研究现状

Classification of flow-induced vibration of centrifugal power gas pipeline and its research status

  • 摘要: 针对流体诱发离心式动力输气管道振动问题,对当前研究成果进行了梳理与总结,将其分为流激湍动、流致振动及声致振动3种类型,分别阐述了振动机理和振动特点,并提出了振动的预防方法及解决措施。为了更好地预防管道振动,提出以下建议:在管道设计阶段,应该根据Energy Institute提出的准则筛查管道振动的可能诱发情况;在管道运营阶段,应该结合管道结构、运行工况及振动特征进行分析,确定振动类型,进而采取相应的解决措施。最后,指出了在流体诱发离心式动力输气管道振动领域尚待解决的重要问题。

     

    Abstract: Current research on the flow-induced vibration of centrifugal power gas pipelines were sorted out, summarized, and classified into three types, i.e. the flow-induced turbulence, the flow-induced vibration and the acoustic-induced vibration. Definitely, the vibration mechanisms and vibration characteristics were claried, and the prevention methods and solutions of vibration were developed. In order to better prevent the pipeline vibration, the following recommendations were proposed: In the pipeline design stage, the possibility of flow induced pipeline vibration should be screened according to the criteria formulated by Energy Institute, while in the pipeline operation stage, analysis should be conducted with consideration given to the pipeline structure, the operating conditions and the vibration characteristics, so that the vibration type could be determined, and the appropriate measures should be taken. Finally, the important issues to be solved in the field of centrifugal power gas pipeline vibration were pointed out.
