摘要
柱塞泵以及相关管网振动过大的问题,是困扰油田注水泵站安全生产的难题之一,极大的管道振动常常会引起管道的疲劳破裂,从而引发流体泄漏等安全事故。研究了基于颗粒阻尼的专用减振器,并基于有限元与离散元耦合分析算法,建立了颗粒阻尼技术阻尼分析模型,然后利用有限元方法,分析了增加颗粒阻尼前后的设备减振效果,并结合现场测试数据以及空间安装位置,设计了合理的阻尼减振方案,并完成了阻尼器的现场安装与调试,研究发现,增加颗粒阻尼减振后,设备的振动烈度降低57.5%以上,进出口管线降低45%以上,确保了设备的安全运行。
The excessive vibration of plunger pumps and related pipe networks is one of the problems that plague the safety of oilfield water injection pumping stations.Excessive pipe vibration often causes fatigue failure of the pipe,which can lead to safety incidents such as fluid leakage.In this paper,a special damper based on particle damping was studied,and a damping analysis model for particle damping technology was established based on the finite element and discrete element coupling analysis algorithm.Then,the finite element method was used to analyze the vibration reduction effect of the equipment before and after the particle damping was added.Combined with the field test data and the space installation location,a reasonable damping and vibration reduction plan was designed,and the on-site installation and debugging of the damper was completed.It was found through research and development that after the particle damping was added,the vibration intensity of the equipment and the outlet pipeline were reduced by more than 57.5%and more than 45%respectively.The safe operation of the equipment has been ensured.
