本科毕业论文（设计）论文题目量化注入式泡沫灭火系统设计学生姓名所在院系机电学院所学专业机电技术教育导师姓名完成时间摘要泡沫消防系统中，大规模泡沫消防工程对泡沫混合液的供给源提出了更高的要求，传统的贮罐压力式泡沫比例混合装置有限的泡沫液供给量已越来越不适应现代大型泡沫消防工程的要求。因此，可以设想采用一种新的系统，用目前发展比较成熟的交流变频技术进行控制，使泡沫灭火达到一个更有效的水平。关键词泡沫消防变频AbstractFireinthefoamsystem,alargescalebubbleburstingfireworksonthesupplysourceofthemixtureahigherdemand,thetraditionalfoamtankpressuredevicelimitedtheproportionofmixedfoamliquidsupplyhasbecomeincreasinglyunsuitedtomodernlargescalebubbletherequirementsoffireprotectionengineering.Socanimagine,useonenewsystem,adoptdevelopmentripeexchangefrequencyconversiontechnologycontroltothefireextinguishingsystemoffoamcomparativelyatpresent,makethefoamputoutthefireandreachamoreeffectivelevel.KeyWordsFoamFireExchangefrequency目录引言........................................................11设计要求...................................................12量化注入式泡沫灭火系统.......................................12.1工作原理...................................................12.2主要特点...................................................22.3适用范围...................................................23主要构成...................................................24注入式泡沫比例混合装置工作流程................................35系统组件的选择..............................................45.1泡沫液的选择................................................45.2泡沫消防泵的选择............................................55.3控制阀门和管道..............................................65.4泡沫比例混合器..............................................75.5控制系统...................................................85.6泡沫液储罐..................................................85.7泡沫产生装置................................................86系统供水...................................................96.1管道水力计算................................................96.2减压孔板..................................................127量化注入式与平衡式泡沫比例混合装置的比较........................147.1相同之处..................................................147.2不同之处..................................................148结束语....................................................14致谢........................................................15参考文献....................................................15
