乳化液泵的设计毕业论文.doc

I摘要在当今的生产技术领域内，广泛应用着乳化液泵，它与乳化液箱组成乳化液泵站，是井下综合采煤工作面支护设备的动力源泉，是煤矿井下支护作业“外注式单体液压支柱”及“液压支架”的专用小型推移式注液设备。该泵具有体积小、重量轻、操作简便、移动灵活、工作平稳可靠和高效节能安全的特点，尤其空间狭小的坑道口，掘进头，低煤层等地段，更是一般大型泵站无法替代的产品。此次设计乳化液泵主要是因为它在煤矿工业上有主要的应用。在此次设计中，首先采用了对比的方法进行总体方案的设计，确定泵的型式，选用曲轴连杆机构为传动方式的结构型式，将曲线运动转变为直线运动。总体方案确定以后通过液力计算对液力端型式进行选择，根据流体力学及流体机械对传动端的结构型式进行选择。选出电机的型号，考虑到给定的设计参数通过计算确定泵的主要结构尺寸及参数。再通过设计计算进行液力端主要部件液缸体的设计及校核，传动端的主要部件减速机构、曲轴、连杆的设计及校核，经过校核计算，最终设计合理。关键词：柱塞流量往复泵曲柄连杆IIAbstractInthenowadaysfieldofthetechniqueoftheproduction,extensiveusethepumpoftheemulsification,itintegratewiththeemulsificationliquidmakeupofemulsificationpumpingstation.Itisthebottomofawellsyntheticalexcavatecoalworkingfacetimberingfacilityspowerheadspring,itisalsotheappropriativeminitypeprocessinjectingliquidequipmentwhichusescoalminebottomofawelltimberingwork“inthemannerofqutsideinjectingmonocasehydraulicpressureunderpinning”and“hydraulicpressurebracket”.Thepumphavemanytraitseg:smallvolume、lightweight、manipulatesimpleandconvenient、movingagility、workplacidityandcredibility、highefficiency、savingenergysources,safetyandsoon.Especiallyinnarrownessroomagessapostium、grubentrance、lowcoalseamregionandsoon,itisalsothebignesspumpingstationcannotinstead.Inthisaboutdesignthepumpoftheemulsification,theimportanceofthereasonisthatithasextensiveuseatthecoalmineindustry.oncomingdesign,inthefirstplace,adoptingthecontrastmethodgoalongcollectivityprojectdesign,confirmthepumptype,chooseingthecrankconnectspoleorgnizationstransmissionfashionconfigurationstyle.Hadorwouldthecurvesporttransformthebeelinesport.Afterthecollectivityprojectdesign,getacrossliquidmechanicscalculatechoosingfluidforceendconfigurationstyle.Baseshydrodynamicsandhydro-mechanismchooseingthetransmissionendconfigurationstyle.Voteinelectromotorstypeconsideringthegivingdesignparameteroverpasscountingconfirmthepumpmostlyconfigurationdimensionandparameter,aftertheparametermakingcertainbasispowerelectingelectromotorstype.Afterwardspassingreckondesignforthefluidforceendimportantpartliquefyurnbodygoalongdesigningandvalidating,transmissionendsimportantpartseg:decelerateorganization、crankandconnectspolesdesigningandvalidating,comebythevalidateaccounting,atlasttestifythedesignisfeasible.Keywords:Thepillarfillsfluxtoandfropumpcrankconnectspole目录摘要.IAbstract.II第一章绪论.11.1.选题的意义.11.2乳化液泵的用途.11.3设计的理论基础研究的内容及方法.1第二章总体方案的确定.4.泵型的选择及特点.42.1.1机动泵及其共同特点.42.1.2直接作用泵及其特点.52.1.5隔膜泵及其特点.72.1.6卧式泵及其共同特点.72.1.7立式泵及其共同特点.72.2液力端结构型式选择.82.3传动端结构型式选择.8第三章泵的主要结构参数的选择与确定.113.1泵的主要尺寸参数的确定.113.1.2柱塞直径和行程的确定.123.2电动机的选择.153.2.1原动机功率的选择与确定.15第四章主要零部件的设计.194.1液力端主要零部件的设计.194.2传动端主要零部件的设计.214.2.1机体的组成及设计
