摘要
阐述了某大型联合装置项目中进料气液两相流管道的振动问题。首先,根据气液两相流气液相的数据判断管道的流型为环雾状流。通过CAESARⅡ软件对其进行一次应力及二次应力不同工况的校核结果的分析,添加合适支架,使静力分析满足管道自身及其相连的设备、机器以及土建结构的安全后,对管道进行动力分析,并根据分析的结果在进料的水平管道上增设液压阻尼器,有效地减少了管系的振动。
The problem of vibration occurred in the piping for gas-liquid two phases flow used in one integrated unit was described in this article. From the data of gas-liquid flow, the flow type in the piping was determined as mist annular flow. By using CAESAR II, primary and secondary stresses in different conditions were analyzed and checked. When appropriate supports were provided, the results of static analysis for piping, machines and foundation were satisfied. Then, dynamic analysis for the piping system was performed. Based on the analysis result, liquid damper was added in the horizontal piping at inlet. In this way, the vibration occurred in the piping system has been effectively reduced.
