- 摘要:
- 大型活塞式压缩机基础转速较低，传统上采用固定大块体结构，不仅基础的体积和重量都很大，而且动力计算模型也比较复杂，设计参数具有不确定性。而弹簧隔振基础结构边界条件简单清晰，解除了设备、基础块与下部结构的刚性动态耦合，受力明确，构造简单，可靠性和准确度高；隔振效率高达80%以上，能大大降低设备本身和对下部结构的动力作用。文章结合胜利油田油气集输总厂一工程实例，从结构型式、隔振原理、物理参数、动力分析几方面介绍了弹性隔振基础的设计，并简要介绍了弹性隔振基础的安装要点。
Foundation of a large scale pistol compressor works usually at low machine rotation speed.Traditionally it takes the form of fixed massive structure.It not only has a large volume and a heavy weight,but also needs a complicated model for dynamic calculation with some uncertain design parameters.Whereas the elastic vibration isolation foundation has simple and clear structural boundary conditions.It releases the dynamic rigidity coupling among the equipment,foundation block and substructure,and possesses the features of definite actions,simple structure,high reliability and accuracy.The efficiency of vibration isolation can be up to 80% and it reduces effectively the dynamic action of equipment itself on substructure.Associated with an engineering practice of General Oil and Gas Gathering and Transporting Plant of Shengli Oilfield,this paper introduces the design of elastic vibration isolation foundation in aspects of structural form,vibration isolation philosophy,physical parameters and dynamic analysis.Also it puts forward the key installation matters briefly.2006,6(6): 13-15 收稿日期：2006-1-9分类号：TU476.1基金项目：胜利油田分公司计划项目(22033100026)作者简介：郭景洲（1955- ），男，山东莱州人，高级工程师，1982 毕业于山东青岛科技大学。现从事油气储运技术管理工作。参考文献：
