摘要
在设备运行过程中,管道经常会产生振动问题,给设备的安全运行带来严重的隐患。针对管道振动问题,采用主动阻尼装置,通过惯性作动器向振动管道系统施加作动力,实现了对管道振动的主动控制。以某化工企业往复式压缩机出口管线25 Hz的振动为例,搭建门型管道振动实验台进行实验,利用SAP2000软件模拟仿真了主动阻尼装置的减振效果。实验研究了惯性作动器在不同安装位置时主动阻尼装置对管道振动的控制效果,探究了惯性作动器的安装位置对管道系统振动控制效果的影响规律。通过对比惯性作动器安装在所选取的4个位置时的减振效果,得出当作动器安装在振动最大的位置上时,主动阻尼装置对管道整体的减振效果最好。
Pipeline vibration often occurs during equipment operation,and can result in serious safety risks.In an attempt to solve such problems,a control force has been applied to a vibrating pipe system by an inertia actuator,so that active control of the pipeline vibration is achieved by means of an active damping device.Taking the 25 Hz vibration of the reciprocating compressor outlet pipeline in a chemical plant as an example,a vibration pipe test bench was built for experimental studies,and the vibration reduction afforded by the active damping device was simulated by SAP2000.The effect of the active damping device on the pipeline vibration when the inertial actuator was installed in different positions was studied experimentally.By comparing the vibration reduction when the inertial actuator was mounted at four different positions,it was found that the active damping device had the best vibration control effect on the whole pipeline when the actuator was installed in the position with the largest vibration.
