全液压钻机液压系统研究—以ZDY3200S全液压钻机为例摘要钻机作为当今我国钻井作业中最为主要的设备，在我国的钻井作业和矿物勘探等领域占据着举足轻重的地位。论文根据国内外钻机的发展现状，首先分析了目前传统钻机的液压系统，其次介绍了目前国内研究比较多的两类矿物勘探钻机煤矿坑道钻机和全液压钻机，分析其各自液压设计原理，最后通过对比总结，可得到全液压钻机在液压控制方面的优势，并通过仿真分析，对于改进的液压系统进行了验证，对钻机未来发展的趋势的指导。关键词钻机；液压原理；分析AbstractDrillrigasthemostmajorequipmentfordrillingoperationintoday'sChina,areassuchasdrillingandmineralprospectinginourcountryoccupiesapivotalposition.Accordingtothecurrentsituationofdrillingrigs’developmentinChinaandoversee,thepaperanalysisthetraditionalrigs’hydraulicsystemfirst,andintroducesthecurrentcoalminetunneldrillingrigs’hydraulicdesignprinciple,comparethesetwokindsofrigs’hydraulicsystemtogettheadvantageofthehydrauliccontrolandthedirectionoffuturedevelopment.Keywordsdrillingrigs;hydraulicprinciple;analysis目录摘要..............................................................................................................................iAbstract............................................................................................................................ii第1章绪论....................................................................................................................51.1国内外研究现状.................................................................................................51.1.1国内研究现状.............................................................................................51.1.2国外发展现状.............................................................................................51.2钻机的发展概况.................................................................................................61.2.1卧式钻机介绍.............................................................................................71.2.2立式钻机简介.............................................................................................71.3钻机中液压原理的应用现状.............................................................................8第2章传统钻机液压系统功能与分析........................................................................92.1常见钻机液压系统.............................................................................................92.1.1单泵液压系统.............................................................................................92.1.2双泵液压系统...........................................................................................102.1.3多泵液压系统...........................................................................................102.2传统钻机液压系统基本回路...........................................................................112.2.1回转液压回路...........................................................................................112.2.2调压限压回路...........................................................................................112.2.3调速回路...................................................................................................122.2.4给进液压回路...........................................................................................132.2.5压力控制回路...........................................................
