Maximizing cov cuab yeej ua tau zoo thiab ua kom ruaj khov ntau lawm tseem yog qhov kev xav tau ceev tshaj plaws ntawm cov tuam txhab hlau thiab hlau. Qhov tsis ua haujlwm ntawm cov khoom siv tseem ceeb ntawm cov dov zeb yuav cuam tshuam rau kev ua haujlwm ntawm kev ua haujlwm thiab kev nyab xeeb ntawm cov dov zeb, thiab dhau los ua qhov mob ntawm cov txheej txheem ntawm "kev hloov pauv ntse" ntawm cov tuam txhab steel.
Kev ua haujlwm nyuaj
Bearing tawb kwv yees yog qhov nyuaj dua:
Raws li SKF txheeb cais:
Txij li thaum 2021,92 feem puantawm cov dov zeb gearbox bearing tsis ua haujlwm kuaj pom hauv kev lag luam steel yog cov kabmob pob txha pob txha (ob leeg nrog thiab tsis ceeb toom).
Hauv 10 xyoo dhau los, 57 qhov xwm txheej tsis ua haujlwm gearbox raug kuaj xyuas thiab tshuaj xyuas, thiab qhov teeb meem ntawm lub tawb nqa tau suav tias yog siab li.58 feem pua.
Lub luag haujlwm tseem ceeb ntawm lub tawb nqa khoom yog cais cov dov cov ntsiab lus, sib npaug ntawm cov khoom thauj thiab coj cov dov cov ntsiab lus kom ua haujlwm ib txwm. Raws li qhov tsis yog qhov tseem ceeb ntawm kev ntxhov siab, nws qhov hardness thiab lub zog yog qis dua lwm qhov ntawm cov kabmob.
(Hauv kev siv steel dov,complex ua hauj lwm tej yam kev mob xws li alternating loads,Kev poob siab txawv txav, thiab qhov sib txawv ntawm qhov ceev ua rau cov kabmob pob txha muaj zog heev.)
Los ntawm kev txheeb xyuas cov yam ntxwv ntawm kev ua haujlwm ntawm dov ntau lawm, peb pom tias kev siv qhov kev kwv yees txij nkawm ntawm dov zeb gearboxes nthuav tawm ntau yam teeb meem:
1.Lub hauv paus ntawm qhov teeb meem txhaum yog qhov nyuaj rau kev paub qhov txawv
Kev cuam tshuam los ntawm kev ua haujlwm nyuaj,cov teeb liab cuam tshuam muaj kev cuam tshuam ntau heev;thiab lub zog ntawm lub teeb liab puas yog attenuated thaum lub sij hawm kis tau tus mob,thiab cov teeb liab tau txais txiaj ntsig tsis muaj zog heev;
2.Image Cov kev soj ntsuam feem ntau muaj qhov ntsuas qhov tseeb tsawg
Feem ntau cov qauv kev coj ua tsis tuaj yeem ua kom tau txais txiaj ntsig zoo ntawm cov teeb meem hauv lub tawb, thiab ua tsis tauntsuas kev puas tsuaj thiab qhov hnyav ntawm kev puas tsuaj;
3.Image Residual lub neej tsis tuaj yeem kwv yees
Lub sijhawm ceeb toom ntawm feem ntau txoj kev tshuaj ntsuam yogfeem ntau luv heev,thiab nws tsis tuaj yeem txhais cov kev hloov pauv tsis zoo thiab kho cov khoom seem thiab cov tswv yim txij nkawm hauv lub sijhawm.
Rolling mill gearbox yog cov khoom siv tseem ceeb ntawm cov hlau dov ntau lawm kab. Cov kabmob tsis ua haujlwm yuav ua rau muaj qhov tshwm sim loj xws li kev poob qis mus ntev, kev poob ntau ntau, thiab kev nce nqi hauv kev saib xyuas thiab kho cov nqi.
Kev xyaum ua tiav
Txhaum Qhov Kev Ua Haujlwm Saib Xyuas Kev Ua Haujlwm Zoo:
Nyob rau hauv 2021, SKF tau ua tiav kev soj ntsuam ntau lub gearbox bearing tawb tsis ua hauj lwm ntawm 2050 kub dov tiav zeb gearboxes ntawm ob lub tsev loj steel zeb cov neeg siv khoom, pab cov neeg siv khoom txo qis kev poob qis thiab tsis txhob nthuav dav.
Nyob rau hauv rooj plaub ntawm cov nroj tsuag steel, SKF online saib xyuas qhov system tau tshaj tawm cov lus ceeb toom ntxov ntxov ntawm kev vibration ntawm lub tswv yim ua haujlwm sab ntawm F4 tiav zeb, thiab qhia txog qhov txawv txav ntawm qhov tshwm sim los ntawm qhov ua txhaum ntawm cov yam ntxwv ntawm lub tawb ntawm lub gearbox. .
(Cov cuab yeej tsav tsheb tseem ceeb ntawm lub tshuab dov yog nruab nrog SKF kev saib xyuas online)
Tom qab tus kws kho mob tau lees paub qhov kev puas tsuaj ntawm cov kabmob tawb, thiabtau muab cov lus qhia txog kev ua kom lub neej ntev tshaj plaws ntawm cov khoom siv, cov cuab yeej tuaj yeem ua haujlwm ruaj khov rau li 4 lub lis piam nrog tus kab mob. Xyuas kom cov neeg siv khoom txaus sijhawm los npaj cov khoom seem ua ntej teem sijhawm rau kev hloov cov kabmob.
Ua ceev faj
Muaj ib daim ntawv qhia rau kwv yees ua ntej:
1.Saib xyuas cov ntsiab lus thiab ntes cov cim siv tau
Cov ntaub ntawv zoo yog qhov yuav tsum tau ua ua ntej rau kev saib xyuas kom raug.
Raws li kev txiav txim siab dav davcov yam ntxwv ntawm cov txheej txheem, cov khoom siv, cov khoom siv load thiab quab yuam, thiab cov cuab yeej siv tsis ua haujlwm ntawm cov hlau dov ntau lawm, SKF dov zeb gearbox kwv yees txij nkawm kev daws teeb meem muaj cov hauv qab nopeb yam ntxwv ntawm daim ntawv thov:
✓ Lub sensor pem hauv ntej yog ze rau qhov chaw thauj khoom ntawm cov kabmob
✓ Lub sijhawm ua piv txwv ntawm cov khoom siv kho vajtse tau txais kev sib koom ua ke nrog cov khoom siv dov
✓ Kev rho tawm ntawm cov teeb liab poob siab thaum dov ntau lawm
Xyuas kom meej tias cov txheej txheem tau txais cov teeb liab ntawm cov dov zeb gearbox yog qhov ua tau zoo thiab cov teeb liab raug siab, thiab muaj txiaj ntsig zoo nrog kev cuam tshuam ntawm kev hloov ceev ceev thiab thauj khoom hloov ntawm lub gearbox thiab cuam tshuam cov teeb liab cuam tshuam.

2.In-depth tsom xam los txhim kho kev kwv yees qhov tseeb
SKF's proprietary acceleration envelope thev naus laus zis (gE), los ntawm kev lim dej tsawg zaus thiab siab-amplitude vibration Cheebtsam, siv cov ntaub ntawv ua tiav cov kabmob thiab muaj peev xwm ua kom muaj kev puas tsuaj ntau zaus, suav nrog kev soj ntsuam kev daws teeb meem raws li cov khoom siv dov, kom ntes tau qhov tshwm sim ntawm kev poob siab. teeb liab nyob rau hauv thaum ntxov theem ntawm bearing tsis ua hauj lwm, thiab muaj peev xwm txheeb xyuas bearing tawb puas ua ntej thiab ua kom raug kev kwv yees.

3.Professional kuaj mob, kwv yees lub neej seem
Ntxiv nrog rau qhov kev kwv yees kom raug, nws tseem yog qhov tseem ceeb rau steel mills los kwv yees cov khoom seem ntawm lub neej. Kev vam khom rau cov kev paub dhau los ntawm cov kws tshaj lij kev tshuaj ntsuam xyuas, SKF tuaj yeem taug qab qhov kev cuam tshuam ntawm kev coj tus kab mob kev puas tsuaj los ntawm kev siv Protean kev kuaj xyuas cov cai hauv kev txheeb xyuas software. Ua ke nrog cov suab nrov ntawm qhov chaw thiab cov khoom thauj khoom, SKF tuaj yeem lees paub qhov hnyav ntawm lub tawb tawg thiab ntsuas lub neej ntawm cov khoom siv. Thiab tsim cov khoom seem thiab cov tswv yim kho.
（SKF Protean Diagnostic Trend Alert）
SKF lub ntse saib xyuas qhov system ua rau muaj kev pheej hmoo ntawm cov cuab yeej tsis nyob qhov twg los nkaum, siv cov ntaub ntawv los qhia kev tsim khoom, pab steel mills ua tau zoo dua kev saib xyuas, thiab tiv thaiv kev ruaj ntseg thiab ruaj khov ntawm kev tsim khoom txhua lub sijhawm.
Nyob rau hauv lub neej yav tom ntej, SKF yuav ntxiv dag zog rau cov tuam txhab metallurgical kom ceev cov kev hloov pauv thiab kev hloov pauv ntawm "kev tsim khoom ntse" los ntawm txoj kev ntse dua thiab huv, thiab txav mus rau lub hom phiaj ntawm kev txhim kho zoo.
