摘要
针对济南某炼油厂丙烷塔空冷器集合管管道振动问题,通过现场测量管道系统的振幅和频率,运用有限元分析软件对管系进行模态分析,并与实测数据进行对比,提出了管系振动的解决方案。在不停机的情况下,在管道的适当位置安装阻尼器,有效降低了管道系统的振幅,提高了管道的运行寿命。
To solve the problem of pipe vibration of the air cooler concentrated pipe of propane tower in a refinery in Jinan,this paper employs finite element analysis software to analyze the pipeline modal by measuring the amplitude and frequency of the pipeline system in the field.It compares the measured results and provides the solution to pipe vibration.Installing viscous dampers to the appropriate location in the piping system when it is in working status may reduce the amplitude of the pipeline effectively and increase the operation life of the pipeline.
