进口渣浆泵/Slurrypump/德国品质德国KAYSEN凯森进口渣浆泵概述渣浆泵(slurrypump)从工作原理上讲属于离心泵,从概念上讲指通过借助离心力(泵的叶轮的旋转)的作用使固、液混合介质能量增加的一种机械,将电能转换成介质的动能和势能的设备。主要适用于:矿山、电厂、疏浚、冶金、化工、建材及石油等行业领域。渣浆泵的名称是从输送介质的角度来划分的一种离心泵。另外渣浆泵从不同角度还可以具体划分不同类型。水泵除了抽水之外,还可以抽气体、固体、固液混合体——矿粉泥浆!水泵用电在***总电量中所占比重很大,水泵的节能情况对国民经济有着重要影响,水泵不但在节能环节中起着积极作用,在火力发电减排流程中也发挥着重要作用。渣浆泵不但比同类产品节能4%-8%,还为大气脱离雾霾“魔爪”做贡献。一般将适用于输送液体(水)中含有悬浮固体物的泵称为渣浆泵。目前是选矿、选煤厂各工艺流程中不可缺少的设备之一。渣浆泵可按不同原则分为单级/多级、单吸/双吸、悬臂、卧式/立式以及泵壳水平中开/垂直结合等型式,如图所示,其基本结构由叶轮、泵壳、泵轴、轴承及托架组成,动力还包括电动机,对轮或胶带轮联轴器等,耐磨件还包括衬板轴套等,密封件包括轴封、副叶轮等,支撑件包括支架等,但内部原理是一致的,当叶轮快速转动时,叶片促使介质很快旋转,旋转着的介质在离心力的作用下从叶轮中飞出,泵内的介质被抛出后,叶轮的中心部分形成真空区域,介质在大气压力(或水压)的作用下通过管网压到了进料管内。这样循环不已,就可以实现连续供料,从而达到工艺设计要求的扬程和流量。当然,入料方式目前多采用压入式,即料位高于入料管,则可以减去从上水管或泵壳向内部***的步骤。主要特点:首先讲述一下离心泵和渣浆泵的关系,然后渣浆泵原理也就自然清晰了。离心概念是从泵原理来讲的。泵有许多种,依据不同的角度可划分几十个类别。离心泵是从泵的工作原理上划分,是通过离心力作用来达到给输送介质增压的过程。另外还有常见的种类包括螺杆原理,柱塞原理等可以划分出不同于离心原理的泵。说完离心泵概念,再说渣浆泵,渣浆泵又是从另外一个角度来划分泵的,即从输送介质来划分的。顾名思义,渣浆泵输送的是含有渣滓的固体颗粒与水的混合物。但从原理上讲渣浆泵属于离心泵的一种。离心泵的主要工作部件是叶轮和机壳,机壳内的叶轮装置位于轴上,并与原动机连接形成一个整体。当原动机机带动叶轮旋转时,叶轮中的叶片迫使流体旋转,即叶片对流体沿它的运动方向做功,从而迫使流体的压力势能和动能增加。与此同时,流体在惯性力的作用下,从中心向叶轮边缘流去,并以很高的的速度流出叶轮,进入压出室,再经扩散管排出,这个过程称为压水过程。同时,由于叶轮中心的流体流向边缘,在叶轮中心形成低压区,当它具有足够的真空时,在吸入端压强的作用下(一般是大气压强),流体经吸入室进入叶轮,这个过程称为吸水过程。由于叶轮连续的旋转,流体也就连续的排出、吸入,形成连续的工作。离心式的泵(包括渣浆泵)的工作过程,实际上是一个能量传递和转化的过程。它将电动机高速旋转的机械能,通过泵的叶片传递并转化为被抽升流体的压能和动能。主要优点:●水力性能好●效率高●磨损率低●流道宽畅●抗堵塞性能好●汽蚀性能优越主要应用:●化工●疏浚●矿山●电力●冶金●煤炭●建材GermanyKAYSENimportedslurrypumpoverviewSlurrypumpisacentrifugalpumpfromtheworkingprinciple.Itconceptuallyreferstoamachinethatconvertstheenergyofsolidandliquidmixedmediabytheactionofcentrifugalforce(rotationoftheimpellerofthepump)toconvertelectricalenergyintoAdeviceforthekineticandpotentialenergyofamedium.Mainlyusedin:mining,powerplants,dredging,metallurgy,chemical,buildingmaterialsandpetroleumindustries.Thenameoftheslurrypumpisacentrifugalpumpthatisdividedfromtheperspectiveoftheconveyingmedium.Inaddition,theslurrypumpcanbedividedintodifferenttypesfromdifferentangles.Inadditiontopumpingwater,thepumpcanalsopumpgas,solid,solid-liquidmixture-mineralmudslurry!Pumppowerc***umptionaccountsforalargeproportionofthecountry'stotalelectricity.Pumpenergyc***ervationhasanimportantimpactonthenationaleconomy.Pumpsnotonlyplayanactiveroleintheenergy-s***ingprocess,butalsoplayanimportantroleinthethermalpowergenerationemissionreductionprocess.Theslurrypumpnotonlys***es4%-8%energycomparedwithsimilarproducts,butalsocontributestotheatmospherefromthe***og"claw".Apumpsuitablefortransportingsuspendedsolidsinaliquid(water)isgenerallyreferredtoasaslurrypump.Itiscurrentlyoneoftheindispensableequipmentsintheprocessofmineralprocessingandcoalpreparation.Theslurrypumpcanbedividedintosingle-stage/multi-stage,single-suction/double-suction,cantilever,horizontal/verticalandhorizontal/verticalcombinationofpumpcasingaccordingtodifferentprinciples.Asshowninthefigure,thebasicstructureisimpeller.Thepumpcasing,thepumpshaft,thebearingandthebracketarecomposedoftheelectricmotor,theoppositewheelorthetapewheelcoupling,thewearpartsfurtherincludetheliningbushing,etc.,andthesealingcomponentincludestheshaftseal,theauxiliaryimpeller,etc.Thepartsincludebrackets,etc.,buttheinternalprincipleisthesame.Whentheimpellerrotatesrapidly,thebladescausethemediumtorotatequickly.Therotatingmediumfliesoutoftheimpellerundertheactionofcentrifugalforce.Afterthemediuminthepumpisthrown,theimpellerThecentralportionformsavacuumregion,andthemediumispressedintothefeedtubethroughthepipenetworkundertheactionofatmosphericpressure(orwaterpressure).Inthisway,continuousfeedingcanbeachievedtoachievetheheadandflowrequiredbytheprocessdesign.Ofcourse,thefeedingmethodiscurrentlymoreindented,thatis,thefillinglevelishigherthanthefeedingtube,andthestepofpouringwaterfromtheupperwaterpipeorthepumpcasingtotheinsidecanbesubtracted.mainfeature:First,let'stalkabouttherelati***hipbetweenthecentrifugalpumpandtheslurrypump,andthentheprincipleoftheslurrypumpisnaturallyclear.Theconceptofcentrifugationisintermsofthepumpprinciple.Therearemanytypesofpumps,whichcanbedividedintodozensofcategoriesdependingontheangle.Thecentrifugalpumpisdividedfromtheworkingprincipleofthepump,andthecentrifugalforceisusedtoachievetheprocessofpressurizingtheconveyingmedium.Therearealsocommontypesincludingtheprincipleofthescrew,theprincipleoftheplunger,etc.,whichcanbedividedintopumpsdifferentfromtheprincipleofcentrifugation.Aftertalkingaboutthecentrifugalpumpconcept,andthentheslurrypump,theslurrypumpdividesthepumpfromanotherangle,thatis,itisdividedfromtheconveyingmedium.Asthenameimplies,theslurrypumpdeliversamixtureofsolidparticlesandwatercontainingdross.Butinprinciple,theslurrypumpisakindofcentrifugalpump.Themainworkingcomponentsofthecentrifugalpumparetheimpellerandthecasing.Theimpellerdeviceinthecasingislocatedontheshaftandisconnectedwiththeprimemovertoformawhole.Whentheprimemoverdrivestheimpellertorotate,thebladesintheimpellerforcethefluidtorotate,i.e.,thebladeperformsworkonthefluidinitsdirectionofmotion,therebyforcingthepressurepotentialandkineticenergyofthefluidtoincrease.Atthesametime,unde
