进口液下泵/Submergedpump/德国品质德国KAYSEN凯森进口液下泵概述液下泵是一种正压输送立式泵，可有效解决气阻、气蚀问题。输送物料的防爆等级决定了液下泵产品具有不同的结构、工作原理、分类、适用范围、产品优缺点和操作方式，可简单分为传统液下泵（罐外1区防爆、罐内0区不防爆）和新型液下泵（罐外1区防爆、罐内0区防爆）两大类。主要特点：●能够与CPTANSIB73.1化工泵互换外壳和叶轮●球墨铸铁或双相不锈钢外壳配合双相不锈钢叶轮，使用寿命长●多种材料的重载荷轴承，可提升耐腐蚀性和高扭矩能力●提供各种液位开关、液位传感器和其他仪器主要应用：广泛应用于油田、炼油、石油化工、化学制品、化肥、***、冶金、食品、纺织、医药和制冷等领域工业系统中,输送不含固体颗粒的******、******、腐蚀性介质及不允许密封污染的介质，不适宜输送含有铁磁性物质的介质。液下泵故障处理及防范措施：液下泵在使用过程中，往往会遇到一些故障，下面介绍几种常见故障，并提供处理方法及防范措施：故障现象：(1)液下泵运行正常不打水。(2)液下泵运行有异音。原因分析：(1)泵吸入口有杂物，堵住液下泵正常运行。(2)水泵检修后电机接线反。(3)泵轴承、轴套磨损严重，造成液下泵叶轮位移，与泵壳发生摩擦。处理方法：(1)清理液下泵入口杂物。(2)联系电热重新调换电源线相级。(3)拆卸液下泵，更换轴承及轴套，保证水泵叶轮与壳体有足够的间隙。防范措施：(1)加强点检，出现问题及时处理。(2)提高员工的检修工艺培训，严格检修质量。GermanyKAYSENimportedsubmergedpumpoverviewThesubmergedpumpisapositivepressureconveyingverticalpump,whichcaneffectivelysolvetheproblemofairresistanceandc***itation.Theexplosion-proofgradeofthetransportedmaterialdeterminesthatthesubmergedpumpproducthasdifferentstructure,workingprinciple,classification,scopeofapplication,productadvantagesanddisadvantages,andoperationmode.Itcanbeeasilydividedintotraditionalsubmergedpump(explosion-proofzone1outsidethetank,zone0inthetank)Thereistwocategoriesofnon-explosion-proofpumpsandnewsubmergedpumps(explosion-proofinZone1outsidethetankandexplosion-proofinZone0intanks).mainfeature:●AbilitytointerchangehousingandimpellerwithCPTANSIB73.1chemicalpump●Ductileironorduplexstainlesssteelshellwithduplexstainlesssteelimpeller,longservicelife●He***y-dutybearingsofvariousmaterialsforimprovedcorrosionresistanceandhightorquecapacity●Providevariousliquidlevelswitches,liquidlevelsensorsandotherinstrumentsmainapplication:Widelyusedinindustrialsystemssuchasoilfield,oilrefining,petrochemical,chemical,fertilizer,nuclearpower,metallurgy,food,textile,medicineandrefrigeration,conveyingflammable,explosive,toxic,harmfulandcorrosivemediawithoutsolidparticles.Itisnotallowedtosealcontaminatedmedia,anditisnotsuitabletotransportmediacontainingferromagneticsubstances.Submergedpumptroubleshootingandprecauti***:Whenthesubmergedpumpisinuse,itoftenencounterssomefaults.Thefollowingdescribesseveralcommonfaults,andprovidestreatmentmethodsandpreventivemeasures:Faultphenomenon:(1)Thesubmergedpumpoperatesnormallywithoutwater.(2)Thesubmergedpumpoperateswithabnormalsound.CauseAnalysis:(1)Thereisdebrisinthesuctionportofthepumptoblockthenormaloperationofthesubmergedpump.(2)Afterthepumpisoverhauled,themotorwiringisreversed.(3)Thepumpbearingandbushingareseriouslyworn,causingdisplacementofthesubmergedpumpimpellerandfrictionwiththepumpcasing.Approach:(1)Cleanuptheinletdebrisofthesubmergedpump.(2)Reconnectthepowerlinephasebycontactingtheelectricheater.(3)Disassemblethesubmergedpump,replacethebearingandthebushingtoensuresufficientclearancebetweenthepumpimpellerandthehousing.Precauti***:(1)Strengthentheinspectionanddealwithproblemsinatimelymanner.(2)Improvethemaintenanceprocesstrainingofemployeesandstrictlycontrolthequality.)
