进口污泥螺杆泵/Screwpump/德国品质德国KAYSEN凯森进口污泥螺杆泵概述进口污泥螺杆泵是一种内啮合的密闭式螺杆泵，属转子式容积泵，污泥单螺杆泵对介质的适应性强，流动平稳，压力脉动小，自吸能力高，这是其它任何泵种所不能替代的。污泥螺杆泵零件少，结构紧凑，体积小，维修简便，转子和定子是本泵的易损件，结构简单，便于装拆。主要特点：●污泥螺杆泵在负压下也能输送含有气体固体混合物的介质。●污泥螺杆泵可以输送含有纤维物和固体颗粒的液体。●污泥螺杆泵振动小，无脉动，运行平稳，流量稳定。●污泥螺杆泵自吸性能好，吸入性能好。●污泥螺杆泵低粘度、高粘度、腐蚀性液体都可以输送。主要应用：适用范围：石油、化工、食品、纺织、造纸、造船、建筑、核工业、冶金与矿工。螺杆泵工作原理及故障排除：一，G型单螺杆泵转子与定子同转,泵无法正常输送泥浆,造成这样的故障可能是固定定子的4颗螺母松弛。解决方法是将泵排出口的4颗螺母拧紧。这里要注意泵排出口的4颗螺母下两个螺母对面有固定螺母,要先松,后紧。上两螺母对面没有固定螺母,所以可以直接进行松紧。二，G型单螺杆泵使用时有声响且声响过大,造成原因可能是泵排出介质量不足,造成泵工作时声响过大。解决方法是可以将排出口的蝶阀关小。这里也要特别注意控制好压力,不要将排出口一次性关闭。如不确定压力,可调节关闭多次蝶阀,勿造成泵超过工作压力。三，另外还有另外的问题，紧4颗螺母也无法解决转子与定子同转。造成原因可能是介质中杂质较多,将转子与定子之间缝隙卡死,带动转子与定子同转。解决方法:可找6根钢筋,将泵体旱死（一边三根）,也就是将定子固定牢固。之后拆解泵体。注意两点1.拆解过程中要注意泵本身可能会有残压,应将法兰略松一点,待压力散尽。2.对泵进行放液。放液口在泵体中部,变速箱的前段,将放液口“慢”松,注意喷出来的杂质。四，***后一个问题，G型单螺杆泵使用时有声响,并且声响不大,各别泵在使用过程中,泵出口略有声响属于正常现象。造成原因有以下三点:1.G型单螺杆泵泵为3级泵,在使用过程中,介质由一个舱室挤压到另一个舱室,压力节节攀高,会略有声响。2.G型单螺杆泵泵内有空气,随着压力***,会被挤压***,造成声响,一般情况下使用一段时间后声响就会消失。3.G型单螺杆泵安装不当,将泵安装过高,泵使用过程中造成泵体晃动,使泵有声响。如泵体内有声响,是由于安装过高,泵内介质受挤压状况造成。GermanyKAYSENimportedsludgescrewpumpoverviewTheimportedsludgescrewpumpisaninternalmeshingclosedscrewpump,whichisarotortypepositivedisplacementpump.Thesludgesinglescrewpumphasstrongadaptabilitytothemedium,stableflow,***allpressurepulsationandhighself-primingability.Thisisanyother.Pumpscannotbereplaced.Thesludgescrewpumphasfewparts,compactstructure,***allvolumeandeasymaintenance.Therotorandstatorarethewearingpartsofthepump,andthestructureissimpleandeasytoassembleanddisassemble.mainfeature:●Thesludgepumpcanalsotransportamediumcontainingamixtureofgaseoussolidsundernegativepressure.•Thesludgescrewpumpcantransportliquidscontainingfibrousandsolidparticles.●Thesludgescrewpumphas***allvibration,nopulsation,stableoperationandstableflow.●Sludgescrewpumphasgoodself-primingperformanceandgoodsuctionperformance.●Sludgescrewpumpcantransportlowviscosity,highviscosityandcorrosiveliquid.mainapplication:Scopeofapplication:petroleum,chemical,food,textile,paper,shipbuilding,c***truction,nuclearindustry,metallurgyandminers.Screwpumpworkingprincipleandtroubleshooting:First,theG-typesingle-screwpumprotorrotateswiththestator,andthepumpcannottransportthemudnormally.Thefailuremaybethatthefournutsofthefixedstatorareslack.Thesolutionistotightenthe4nutsofthepumpdischarge.Here,payattentiontothefournutsofthepumpdischargeport.Therearefixingnutsontheoppositesidesofthetwonuts.Itmustbeloosefirstandthentight.Thereisnofixingnutontheoppositesideoftheuppertwonuts,soitcanbetighteneddirectly.Second,theG-typesingle-screwpumphasanaudiblesoundandthesoundistooloud.Thecausemaybethatthepumpdischargemediumisinsufficient,causingthesoundtobetooloudwhenthepumpisworking.Thesolutionistoclosethebutterflyvalveofthedischargeport.Specialattentionshouldalsobepaidheretocontrollingthepressure.Donotclosethedischargeportatonetime.Ifthepressureisuncertain,thebutterflyvalvecanbeclosedmultipletimeswithoutcausingthepumptoexceedtheworkingpressure.Third,thereisanotherproblem.Thefournutscannotsolvethesamerotationoftherotorandthestator.Thecausemaybethattherearemanyimpuritiesinthemedium,andthegapbetweentherotorandthestatorisstuck,andtherotorandthestatorarerotatedtogether.Solution:Youcanfind6steelbarsanddrythepumpbody(threeononeside),thatis,fixthestatorfirmly.Thendisassemblethepumpbody.Payattentiontotwopoints.1.Duringthedisassemblyprocess,payattentiontotheresidualpressureofthepumpitself.Theflangeshouldbeslightlylooseneduntilthepressureisexhausted.2.Dischargethepump.Theliquiddischargeportisinthemiddleofthepumpbody,andthefrontpartofthegearboxis“slow”loose,payingattentiontotheimpuritiesemitted.Fourth,thelastproblem,theG-typesingle-screwpumphassoundwhenitisused,andthesoundisnotloud.Itisnormalforthepumpoutlettosoundslightlyduringtheuseofthepump.Therearethreereas***forthis:1.TheG-typesingle-screwpumpisa3-stagepump.Duringuse,themediumissqueezedfromonecompartmenttotheother,andthepressureisrampedupandwillsoundslightly.2.ThereisairintheG-typesingle-screwpump.Asthepressureincreases,itwillbecrushedandruptured,causingsound.Undernormalcircumstances,thesoundwilldisappearafteraperiodofuse.3.TheG-typesingle-screwpumpisimproperlyinstalled,thepumpisinstalledtoohigh,andthepumpbodyisshakenduringtheuseofthepump,sothatthepumpsounds.Ifthereissoundinthepumpbody,itiscausedbytheinstallationbeingtoohighandthemediuminsidethepumpissqueezed.)
