摘要
针对丙烯压缩机进口管线气液过滤分离装置存在较大的振动问题,采用ANSYS软件建立整体管道模型并计算其模态,利用SAP2000软件模拟对比施加阻尼前、后管道振动情况,并优化设计阻尼器的安装方案;最后在不停工的情况下,对管线进行阻尼减振改造。改造后离心压缩机主管线振动幅值平均减小75%,监测仪表处最大振幅从1 900μm降低至350μm,降幅81. 6%;液位计最大振幅从2 300μm降至320μm,降幅86. 1%。该阻尼减振技术有效控制了主管线振动的同时也降低了监测仪表与液位计的振幅,保证了压缩机的稳定工作以及生产安全。
To address the large vibration problem of the gas-liquid filtration and separation device of the propylene compressor inlet pipeline,the ANSYS finite element software is used to establish the overall pipeline model and calculate its modal to analyze the cause of pipeline vibration.The SAP2000 software is used to simulate and compare the vibration of the pipeline before and after the damping.The installation scheme of the damper is optimized.The pipeline is installed with damper without stopping working.After the installation,the vibration amplitude of the main line of the centrifugal compressor is reduced by 75%on average,and the maximum amplitude of the monitoring instrument is reduced from 1 900μm to 350μm,a decrease of 81.6%.The maximum amplitude of the liquid level gauge is reduced from 2 300μm to 320μm,a decrease of 86.1%.The vibration damping technology effectively controls the vibration of the main line and reduces the amplitude of the monitoring instrument and the liquid level gauge,ensuring stable operation of the compressor and production safety.
