摘　　要：石景山热电厂原有 8.5E(ZQM - 2 16型 )中速磨煤机 ,由于它的一些缺点需改换成ZGM - 95G型磨煤机。在改造工程中 ,由于场地的限制 ,要使用弹簧隔振基础。在浇注了台座块混凝土基础后 ,进行了弹簧隔振元件的安装。磨煤机运行后 ,对弹簧隔振基础的振动进行了测试。测试结果表明 :磨煤机隔振基础的隔振效率高 ,1号炉达到 90 % ,3号炉达到 91% ,与未安装弹簧隔振基础的 2号炉和 4号炉相比 ,隔振效果显著。Shijingshan Thermal Power Plant had 8.5E roll mill pulverizer(model ZQM-216).Due to some shortcomings they need to be replaced with a model ZGM-95G mill.During the innovation project the spring vibration-isolated foundation is required due to limitation of the site.After pouring the concrete foundation of bench block,the spring vibration isolated elements are installed.After operation of the mill the test and measurement for vibration of the foundation are executed.The results represent:the vibration-isolation efficiency of the foundation is high,90% for mill in No.1 boiler and 91% for mill in No.3 boiler.Compared with mill in No.2 and No.4 boilers without spring vibration-isolated foundations,the vibration isolation result is obvious.
