进口耐腐蚀离心泵/Centrifugalpump/德国品质德国KAYSEN凯森进口不锈钢离心泵概述卧式单级单吸离心泵采用******的水力模型，根据IS型单级单吸离心泵之性能参数和立式泵的独特结构组合设计，并严格按照国际iso2858进行设计制造，该产品轴封选用硬质合金机械密封装置，具有***节能、性能可靠、安装使用方便等特点。通过不锈钢离心泵与管路系统的特性曲线图分析了离心泵流量调节的几种主要方式：出口阀门调节、泵变速调节和泵的串、并联调节。用特性曲线图分析了出口阀门调节和泵变速调节两种方式的能耗损失，并进行了对比，指出离心泵用变速调节流量比用出口阀门调节流量可以更好的节约能耗，且节能效率与流量变化大小有关。在实际应用时应该注意变速调节的范围，才能更好的应用离心泵变速调节。不锈钢离心泵是广泛应用于化工工业系统的一种通用流体机械。它具有性能适应范围广（包括流量、压头及对输送介质性质的适应性）、体积小、结构简单、操作容易、操作费用低等诸多优点。通常，所选离心泵的流量、压头可能会和管路中要求的不一致，或由于生产任务、工艺要求发生变化，此时都要求对泵进行流量调节，实质是改变离心泵的工作点。离心泵的工作点是由泵的特性曲线和管路系统特性曲线共同决定的，因此，改变任何一个的特性曲线都可以达到流量调节的目的。离心泵的流量调节方式主要有调节阀控制、变速控制以及泵的并、串联调节等。由于各种调节方式的原理不同，除有自己的优缺点外，造成的能量损耗也不一样，为了寻求***佳、能耗***小、***节能的流量调节方式，必须***地了解离心泵的流量调节方式与能耗之间的关系。主要特点：不锈钢离心泵盖通过止口固定要中间支架上,然后通过泵体与中间支架止口的连接把泵盖夹紧在中间.泵体是轴向吸入,径向排出,脚支承式,可直接固定在底座上.悬架部件通过止口固定在中间支架上,并用悬架支架支撑在底座上.为拆卸方便,设计了加长联轴器,检修时可以不拆卸进出口联接管路、泵体和电动机。只需拆下长联轴器的中间联接件，即可退出转子部件进行检修。这是国际上一种通用的结构形式。泵的密封型式采用填料密封或机械密封，由用户根据需要选用，同时根据需要允许采用适合于IS03069规定的密封空腔尺寸的其他结构的轴封型式（如带波纹管的机械密封和付叶轮密封等等）。主要优点：●维修方便：更换密封、轴承、简易占地更省：出口可向左、向右、向上三个方向，便管道布置安装，节省空间●运行平稳：泵轴的***同心度及叶轮优异的动静平衡，保证平稳运行，***振动●噪音低：两个低噪音的轴承支撑下的水泵，运转平稳，除电机微弱声响，基本无噪音●故障率低：结构简单合理，关键部分采用国际***品质配套，整机无故障工作时间大大提高●滴水不漏：不同材质的硬质合金密封，保证了不同介质输送均无泄漏主要应用：●卧式化工泵，供输送不含固体颗粒，具有腐蚀性、粘度类似于水的液体，适用于石油、化工、冶金、电力、造纸、食品制药和合成纤维等部门，使用温度为-20℃～+120℃●卧式管道油泵，供输送***、煤油、柴油等油类产品或***、***液体，被输送介质温度为-20～+120℃●卧式清水离心泵，供输送清水及物理化学性质类似于清水的其它液体之用，适用于工业和城市给排水、高层建筑增压送水、园林喷灌、消防增压、远距离输送、暖通制冷循环、浴室等冷暖水循环增压及设备配套，使用温度t≤80℃●卧式热水泵广泛适用于：冶金、化工、纺织、造纸以及宾馆饭店等锅炉热水增压循环输送及城市采暖系统，iswr型使用温度t≤120℃GermanyKAYSENimportedstainlesssteelcentrifugalpumpoverviewThehorizontalsingle-stagesingle-suctioncentrifugalpumpadoptsthemostadvancedhydraulicmodel.ItisdesignedaccordingtotheperformanceparametersoftheIS-typesingle-stagesingle-suctioncentrifugalpumpandtheuniquestructureoftheverticalpump.Itisdesignedandmanufacturedinstrictaccordancewiththeinternationaliso2858.Thehardalloymechanicalsealingdeviceisadopted,whichhasthecharacteristicsofhighefficiency,energys***ing,reliableperformance,convenientinstallationanduse.Throughthecharacteristiccurveofthestainlesssteelcentrifugalpumpandthepipelinesystem,severalmainwaysofadjustingtheflowofthecentrifugalpumpareanalyzed:theoutletvalveadjustment,thepumpshiftregulationandtheseriesandparalleladjustmentofthepump.Thecharacteristiccurveisusedtoanalyzetheenergylossofthetwomethodsofoutletvalveregulationandpumpspeedregulation.Thecomparisonshowsthatthevariablespeedregulationflowofthecentrifugalpumpcans***eenergyands***eenergybyadjustingtheflowratewiththeoutletvalve.Itisrelatedtothesizeoftheflowchange.Inpracticalapplicati***,attentionshouldbepaidtotherangeofshiftregulationtobetterapplythecentrifugalpumpshiftregulation.Stainlesssteelcentrifugalpumpsareageneral-purposefluidmachinewidelyusedinchemicalindustrialsystems.Ithasawiderangeofperformance(includingflow,pressureheadandadaptabilitytothenatureofthetransportmedium),***allsize,simplestructure,easyoperation,lowoperatingcostsandmanyotheradvantages.Usually,theflowrateandpressureheadoftheselectedcentrifugalpumpmaybeinc***istentwiththerequirementsinthepipeline,orduetochangesinproductiontasksandprocessrequirements.Atthistime,theflowadjustmentofthepumpisrequired,whichessentiallychangestheworkingpointofthecentrifugalpump.Theworkingpointofthecentrifugalpumpisdeterminedbythecharacteristiccurveofthepumpandthecharacteristiccurveofthepipingsystem.Therefore,changingthecharacteristiccurveofanyonecanachievethepurposeofflowregulation.Theflowadjustmentmodeofthecentrifugalpumpmainlyincludestheregulatingvalvecontrol,thevariablespeedcontrol,andtheparallelandseriesadjustmentofthepump.Duetothedifferentprinciplesofvariousadjustmentmethods,inadditiontotheirownadvantagesanddisadvantages,theenergylossisnotthesame.Inordertofindthebest,thelowestenergyc***umption,themostenergy-s***ingflowregulation,itisnecessarytofullyunderstandtheflowregulationofthecentrifugalpump.Therelati***hipbetweenmodeandenergyc***umption.mainfeature:Thestainlesssteelcentrifugalpumpcoverisfixedtotheintermediatebracketthroughthestop,andthenthepumpcoverisclampedinthemiddlebytheconnectionbetweenthepumpbodyandtheintermediatebracket.Thepumpbodyisaxiallysucked,radiallydischarged,andthefootissupportedandcanbedirectlyfixed.Onthebase,thesuspensioncomponentisfixedontheintermediatebracketthroughthestop,andissupportedonthebasebythesuspensionbracket.Fortheconvenienceofdisassembly,theextensioncouplingisdesigned,andtheinletandoutletconnectionpipeline,thepumpbodyandtheelectricmotor.Simplyremovetheintermediatecouplingofthelongcouplingandexittherotorassemblyforinspection.Thisisacommonformofstructureintheworld.Thesealtypeofthepumpadoptspackingsealormechanicalseal,whichisselectedbytheuserasneeded,andothertypesofshaftsealtype(suchasmechanicalsealwithbellowsandimpellerseal)whicharesuitableforthesealedc***itysizespecifiedbyIS03069areallowedasrequired.andmanymore).Themainadvantage:●Convenientmaintenance:replacementofseals,bearings,andsimplelandoccupation:theexitcanbeleft,right,andupward,andthepipelinesareinstalledandinstalledtos***espace.●***oothoperation:absoluteconcentricityoft
