I摘要本設(shè)計(jì)在分析了鉆床技術(shù)要求的基礎(chǔ)上,根據(jù)立式鉆床的特點(diǎn)和要求，進(jìn)行它的液壓系統(tǒng)設(shè)計(jì)，重點(diǎn)介紹這種鉆床的液壓系統(tǒng)工作原理、液壓系統(tǒng)的設(shè)計(jì)、閥塊塊設(shè)計(jì)和油箱及液壓泵站的設(shè)計(jì)。該液壓系統(tǒng)性能良好,工作穩(wěn)定。本次畢業(yè)設(shè)計(jì)的題目是鉆床液壓系統(tǒng)的設(shè)計(jì),設(shè)計(jì)時(shí)考慮的功能比較齊全。由于本系統(tǒng)的壓力小(3MPa),流量小,普通的滑閥就能滿足其要求。鉆床液壓泵站是近年來發(fā)展起來的設(shè)備，自動(dòng)化程度較高。本文先對(duì)鉆床液壓系統(tǒng)的要求進(jìn)行了闡述，并對(duì)設(shè)計(jì)要求和設(shè)計(jì)步驟進(jìn)行了說明。主要是對(duì)閥，泵，馬達(dá)和缸的選取，油箱，閥塊及閥組的設(shè)計(jì)，系統(tǒng)的性能較核與驗(yàn)算為主。并且對(duì)本液壓系統(tǒng)的保養(yǎng)與維護(hù)有著詳細(xì)的說明和要求。近30年來，由于原子能技術(shù)、航空航天技術(shù)、控制技術(shù)、材料科學(xué)、微電子技術(shù)等學(xué)科的發(fā)展，再次將液壓技術(shù)推向前進(jìn)，使它發(fā)展成為包括傳動(dòng)、控制、檢測(cè)在內(nèi)的一門完整的自動(dòng)化技術(shù)，在國民經(jīng)濟(jì)的各個(gè)部門都得到了應(yīng)用，如工程機(jī)械、數(shù)控加工中心、冶金自動(dòng)線等。采用液壓傳動(dòng)的程度已成為衡量一個(gè)國家工業(yè)水平的重要標(biāo)志之一。關(guān)鍵詞：液壓系統(tǒng)；液壓技術(shù)；液壓泵站IIAbstractThedesignoftheanalysisofthedrillingmachinetechnologyrequest,basedonthecharacteristicsofverticaldrillingandrequirementsforthehydraulicsystemdesign,whichfocusesonthedrillinghydraulicsystemprinciple,hydraulicsystemdesign,Valvedesignandhorizontaltankandpumpstationdesign.Thehydraulicsystemisingood,stablejobs.TheDesigngraduateRockeristhesubjectofdrillingmachinehydraulicsystemdesign,designconsiderationsofthefunctionofarelativelycomplete.Duetothepressureofthesystemissmall(C306),flowofsmall,ordinaryslidevalvewillbeabletomeetitsrequirements.Drillinghydraulicstationisdevelopedinrecentyearsforequipment,ahigherdegreeofautomation.Thearticlefocusesonthedrillinghydraulicsystemtotherequirementsofthepaper,thedesignrequirementsanddesignstepsdescribed.Themainvalve,pump,motorandcylinderselection,tanks,valvesandvalveblocktotheblockdesign,theperformanceofthesystemthannuclearandmainlychecking.Andtherighthydraulicsystemmaintenanceandmaintenanceisadetaileddescriptionandrequirements.Nearly30years,asaresultofnuclearenergytechnology,aerospacetechnology,controltechnology,materialscience,microelectronicstechnologydisciplines,suchasthedevelopmentofhydraulictechnologywillonceagainpushforwardintoit,includingtransmission,control,Detectionofacompleteautomationtechnology,ineverysectorofthenationaleconomyhavebeenapplied,suchasengineeringmachinery,CNCMachiningCenter,metallurgicalautomaticlanes.HydraulicDrivehasbecomeanationalindustrialmeasuringthelevelofoneoftheimportantsigns.Keywords:hydraulicsystems；hydraulictechnology；pumpstation目錄前言-1-1緒論-2-1.1課題選擇的意義-2-1.2液壓系統(tǒng)在工程中的應(yīng)用-3-1.3液壓傳動(dòng)系統(tǒng)的優(yōu)缺點(diǎn)-3-1.3.1優(yōu)點(diǎn)-4-1.3.2缺點(diǎn)-5-2.1液壓系統(tǒng)的設(shè)計(jì)步驟-6-2.2設(shè)計(jì)要求-6-2.3鉆床對(duì)液壓系統(tǒng)的要求-7-3液壓系統(tǒng)方案設(shè)計(jì)-8-3.1制定調(diào)速方案-8-3.2制定壓力控制方案-8-3.3制定順序動(dòng)作方案-9-3.4選擇液壓動(dòng)力源-9-3.5繪制液壓系統(tǒng)圖-10-4液壓執(zhí)行元件的設(shè)計(jì)計(jì)算與選用-12-4.1確定液壓系統(tǒng)的主要參數(shù)-12-4.1.1鉆床機(jī)床控制液壓系統(tǒng)的主要設(shè)計(jì)參數(shù)-12-4.1.2初步估算系統(tǒng)工作壓力-12-4.1.3系統(tǒng)工作流量的選擇-12-4.2管道尺寸的確定-13-4.3各種閥類的選擇-13-4.3.1換向閥的選取-13-4.3.2單向閥的選擇-14-4.3.3減壓閥的選擇-14-4.3.4壓力繼電器的選擇-14-4.4液壓泵的選擇-15-4.5液壓泵驅(qū)動(dòng)電機(jī)的選擇-15-4.6液壓馬達(dá)的選取-16-4.7確定油箱的有效容積-16-4.8液壓缸的載荷力計(jì)算-17-5系統(tǒng)性能驗(yàn)算-18-5.1沿程壓力損失-18-5.2局部壓力損失-18-6系統(tǒng)發(fā)熱量的計(jì)算-20-6.1計(jì)算發(fā)熱功率-20-6.2計(jì)算散熱功率-20-7液壓系統(tǒng)安裝、調(diào)試、維護(hù)-22-7.1安裝前的技術(shù)準(zhǔn)備工作-22-7.1.1液壓元件質(zhì)量檢查-22-7.1.2液壓輔件質(zhì)量檢查-23-7.1.3管子和接頭質(zhì)量檢查、管接頭壓力等級(jí)
