Yuav tshuaj xyuas thiab kho cov kab rov tav centrifugal slurry twj tso kua mis li cas
(1) lub impeller lub impeller thiab lwm qhov chaw kho kev sib txhuam abrasion generated, vuam txoj kev kho.Rau lub impeller ntawm cov khoom sib txawv, txoj kev vuam sib txawv.Tom qab vuam, yuav tsum tau nyob rau hauv lub tshuab dhos, lub surfacing txheej tsheb mus rau tus thawj loj.Cov txheej tuab tsim los ntawm cov kua qaub, alkali rau impeller corrosion los yog yaig ntawm cov xov xwm thinning, stomatal cam khwb cia hlau impeller los yog slag thiab cov kab nrib pleb tshwm sim los ntawm kev co los yog kev sib tsoo, nyob rau hauv ib txwm xwm txheej tsis kho, tuaj yeem siv cov khoom seem los hloov cov tshiab.Txawm li cas los xij, yog tias koj yuav tsum kho, "kho welding method" los kho.Kho vuam ntawm impeller, raws li cov ntaub ntawv sib txawv, siv ntau txoj kev kho vuam.
(2) cylindrical impeller inlet kawg thiab qhov hluav taws xob kawg, qhov radial runout feem ntau yuav tsum tsis pub tshaj 0.05mm.Yog tias ntau tshaj qhov tsis txaus (hauv 0.1 hli), tuaj yeem ua rau hauv tshuab dhos rau 0.06 ~ 0.1 hli, uas yog raws li qhov yuav tsum tau ua.Yog tias muaj ntau tshaj, yuav tsum ncaj nraim kev sib txawv ntawm cov slurry twj tso kua mis ncej loj heev, tuaj yeem siv txoj kev ncaj nraim los kho, tshem tawm cov impeller radial runout.
Lub tes tsho kho ncej yog centrifugal slurry twj tso kua mis hnav qhov chaw.Yog tias qhov hnav me me, tsuas yog qee qhov hnav qis heev, txoj hauv kev tuaj yeem siv los kho vuam, vuam thiab tig mus rau qhov loj me, tseem tuaj yeem siv txuas ntxiv.Yog tias hnav hnyav dua, hnav caws pliav tob, koj yuav tsum hloov lub tes tsho tshiab.
(3) kab rov tav centrifugal slurry twj tso kua mis ncej dabtsi yog khoov kev taw qhia ntawm kev kho cov slurry twj tso kua mis ncej thiab tus nqi ntawm dabtsi yog khoov yog ntsuas tawm, yog hais tias tus dabtsi yog khoov tus nqi ntau tshaj qhov tso cai, koj siv tau txoj kev ncaj, lub slurry twj tso kua mis ncej straightening.Los ntawm slurry twj tso kua mis ncej hauv zos hnav, yog hnav qhov tob tsis loj heev, cov khoom hnav nrog vuam txoj kev kho.Vuam yuav tsum tig mus rau qhov loj me me.Yog tias qhov hnav qhov tob loj dua, tuaj yeem "ntxig qhov kho qhov chaw".
(4) ntawm qhov hnav ntawm slurry twj tso kua mis ncej yog loj los yog tawg, feem ntau tsis kho, thiab spare qhov chaw rau hloov.
Sab ntawm slurry twj tso kua mis ncej qhov tseem ceeb, yog tias muaj kev puas tsuaj me, tuaj yeem siv los kho cov ntaub ntawv teeb.Yog tias muaj qhov tshwm sim hnyav dua, yuav tsum siv txoj kev vuam los kho.Kho, ua ntej nrog lub arc vuam ib tug keyway zoo, thiab ces siv lub milling, npaj los yog phau ntawv filing txoj kev, los kho qhov qub loj thiab cov duab ntawm lub keyway.
Tsis tas li ntawd, kuj tuaj yeem siv los hloov txoj haujlwm tseem ceeb ntawm txoj kev kho.Thawj qhov welding ntawm thawj qhov tseem ceeb ntawm txoj hauj lwm, thiab tom qab ntawd ua cov ntaub ntawv nto, ua rau nws qhov chaw curvature radius thiab qag caj dab, thiab tsim ib qho kev sib txuas.Thaum kawg, tus ncej tig 180 DEG, qhov chaw sib txuas tom qab qhov tseem ceeb ntawm txoj haujlwm, raws li qhov loj me thiab cov duab ntawm txoj kev tseem ceeb, tsim txoj haujlwm tshiab.
(5) kev kho ntawm dov bearing txheej nplhaib ntawm lub slurry twj tso kua mis lub cev nyob rau hauv lub bearing qhov slurry twj tso kua mis tig, yuav Zhou Chengkong lub puab lub voj voog sib tsoo tsis xws luag los yog kauj ruam loj, striation thiab lwm yam.. twj lub cev ntaus lub txaj.
1 bearing qhov tho txawv, tom qab ntawd raws li qhov loj ntawm qhov ntxig cov kabmob qhov tho txawv.
2 rau cam khwb cia hlau slurry twj tso kua mis lub cev, tshwm slag los yog tsis xws luag xws li pores, thawj qhov tsis xws luag los ntxuav, thiab ces welding.
3 slurry twj tso kua mis lub cev vim kev co, kev sib tsoo los yog percussion thiab tawg thaum, siv tau oxygen acetylene gas vuam los yog arc vuam.
