Hluav taws xob lub tsheb cav sab hauv
Sib sib zog nqus kev nkag siab ntawm kev txuam nrog sab hauv kev tsav tsheb
Sab hauv ntawm lub cev muaj zog tsis meej heev rau cov neeg caij tsheb. Tom ntej peb taug kev mus rau sab hauv ntawm lub tshuab kom pom seb cov khoom sab hauv yog txhua yam li cas.
Ua ntej, pib nrog cov hlau nplaum uas cov neeg tsav tsheb nyiam tshaj plaws. Muaj ntau hom hlau nplaum hlau, thiab muaj peb yam: hom ferrite, txhuas nickel cobalt, thiab neodymium hlau boron. Raws li lub ntiaj teb tsis tshua muaj hlau nplaum cov khoom, NdFeB tuaj yeem tso tawm ib qho khoom sib zog nqus hluav taws xob hauv ib lub ntim xwb, ua rau nws muaj peev xwm ua kom muaj lub zog DC. Yog li ntawd, ntxiv rau cov khoom siv hluav taws xob ntxov tshaj plaws, lub tshuab fais fab tuag yog ib lub ntiaj teb ntawm NdFeB. Cov hlau nplaum ntawm no tsis yog tus kheej qhov tseeb. Sib nqus hlau yog khoom muag. Txij li nws yog khoom, muaj peb los yog rau 6, yog li ntawd, yuav ua li cas ua cov hlau luam hlau hlau sib txawv ntawm qhov zoo thiab qhov phem? Thawj yog qib. Cov qhabnias hlau qhabnias muaj EH, UH, SH, H, M, N cov kev kawm los ntawm siab mus rau qis, thiab qhov ntsuas kub ua haujlwm coefficient yog 200, 180, 150, 120, 100, 80. . Tom qab tag nrho, lub cav nws tus kheej yuav sov. Tom qab lub tshav kub tsim, lub demagnetization yuav cuam tshuam rau lub neej ntawm lub cev. Nyob rau hauv pem hauv ntej ntawm hlau nqus hlau, yuav muaj feem ntau yog ib tug xov tooj. Tus xov tooj no feem ntau yog 35, 38, 40. Cov phiajcim digital no txhais tau tias muaj cov ntsiab lus khov kho. Ntev npaum li koj paub tias tus lej loj dua, txoj hauv paus ntsiab lus ntawm kev sib nqus zoo yog qhov zoo. Nta, cov motors ntawm kev ua lag luam yog feem ntau ua los ntawm 38M khoom sib nqus hlau nrog kub kub ntawm 100 degrees, thiab tus txheem H khoom sib nqus hlau yuav siv tsis tshua muaj.
Txiav txim xyuas cov khoom thiab ces saib qhov siab. Vim tias txoj haujlwm ua haujlwm ntawm lub cav tsuas yog electromagnetic conversion, ces koj yuav tsum muaj hwj huam txaus los sis txaus kom muaj lub zog txaus, uas yog ua txhua yam kom yuav tsum muaj qhov ntim txaus ntawm sib nqus hlau. Feem ntau, lub tshuab fais fab tuag tsuas yog qhov siab, thiab lub thickness dav tsis cim, thiab lub demagnetization ntawm cov hlau nplaum yog ze rau cov thickness (piv txwv, cov magnetite demagnetization ntawm 3 hli tuab yuav tsis pub tshaj 3% 2 teev nyob rau hauv 100 degree tus qauv, Nyob rau tib qhov chaw ntawm 2.5 hli thickness, lub demagnetization yog nyob rau hauv thaj tsam ntawm 5-8%, thiab lub thickness ntawm ob yog ntau tshaj li 10% In contrast, cov nyhuv ntawm lub dav rau lub cev muaj zog Tsis yog loj heev, Lub suab dub-hearted lub cev twb pib nyob rau hauv lub khw. Au, kuv lub siab.
Tom qab peb ua tiav cov hlau nplaum, peb tau hais tias cov tub ntxhais hlau ua tiav, qhov qub tsav yog ua los ntawm ib daim ntawv ntawm silicon hlau nyob rau hauv lub tshuab fais fab, yog li nws tseem hu ua silicon steel sheet, ob tug yog tib yam. Cov tub ntxhais kawm feem ntau yog qhov txias tshaj plaws (muaj cov nplooj ntawv kub ua kub ua ntej 06), thiab cov qib yog 800, 600, 470, 400, 350, 300 los ntawm siab mus qis. Cov npe no txhais li cas? Noj txias 470 ua piv txwv li, cov nqi hlau tsis yog 4.7w / kg. Qhov kev piav qhia tej zaum yuav nyuaj. Ntev npaum li koj paub tias tus nqi poob hlau tsis zoo rau lub cav, qhov qis dua qhov zoo dua, qhov qis dua qib tuaj yeem tus nqi qis dua, thiab cov nyhuv ntawm txhua cov khoom siv hlau zeb tsis zoo li qub, noj domestic steel raws li ib qho piv txwv, tib lub npe yog qhov zoo tshaj plaws nyob rau hauv WISCO, Baosteel Taigang zoo li taug qab, ntawm chav kawm, qhov zoo tshaj plaws hlau yog imported lub teb chaws Yelemees los yog Nyiv, tsuas yog yuav tsis tshwm nyob rau hauv lub lag luam hluav taws xob kev lag luam.
Tom qab ntawd peb saib ntawm lub xaim hlau loj. Txoj hlua hluav taws xob feem ntau siv los ntawm hluav taws xob lub cev muaj zog tsuas yog ob hom 130-2 los yog 180-1, ces yuav to taub cov ntaub ntawv no li cas? Ntawm lawv, 130 thiab 180 hais txog kev kub ntxhov ntawm kev ua haujlwm ntawm cov hlau xaim, tom qab 180 lawm ib txwm zoo; -1 thiab -2 feem ntau xa mus rau cov xim tho xim thiab xim xim zaj duab xis, uas yog, qhov teeb meem ntawm qhov chaw kub. Tsis muaj citation Yog tias lub tshuab siv 180-1, cov nyhuv yuav zoo tshaj 130-2.
Tom qab ntawd, muaj yim-cuaj kab, uas yog feem ntau hu ua East ntawm kab txhuas. Lub xwmfab XX ntawm lub rooj tsavxwm lub cev yog hais txog thaj tsam ntawm seem peb theem, feem ntau raws li cov cai hauv qab no: 800w los yog luv dua, 1.5 square; 800-1000, 2 square; 1000-1500, 2.5 lossis 3 square; 1500-2000, 6 square; 2000-2500, 8 xwmfab; 2500-3000, 10 square; 3000 nce, dua li 16 square. Yog hais tias koj lub cev muaj zog 1500W ntawm 1.5 square xwb, lub tshuab no muaj peev xwm ua kom muaj zog, vim hais tias lub hwj chim no muaj qhov siab ua rau muaj qhov kab mob no.
Thaum kawg, peb xav txhawm rau txheeb xyuas cov khoom siv ntawm ob lub tshuab hluav taws xob yuav tsum khawb: Bearings thiab Halls, peb tham txog zauv bearings. Kev siv ntawm cov bearings nyob rau hauv kev lag luam machinery feem ntau heev, yog li cas ntawm bearings yog feem ntau haum? Ua ntej tshaj, lub zog ntawm lub cev muaj zog zoo nrog rau qhov loj ntawm kev coj tus kheej. Tus ascas uas muaj kev paub txog kev kho lub tsheb yuav pom meej meej tom qab lem lub hau npog. Tom qab ntawd koj yuav tsum paub hais tias lub cev muaj zog hluav taws xob (li 1500W) yuav tsum sib npaug tsawg kawg yog 6004 (txheej diam 42 hli). Tus txheej txheem yuav lav tau ib lub neej ntawm peb lub xyoos, thiab qhov nce hauv hwj huam yuav tsum muaj kev tuav pov hwm kom muaj lub zog ntawm lub tshuab. Yog tias nws yog hluav taws xob, nws yog qhov yooj yim, muaj 6203 (sab diam 40). Thaum peb ua tiav qhov loj, peb tab tom ua zoo. No lub tuam txhab dav dav yog evasive, vim hais tias cov kabmob tus nqi yog txiav txim siab raws li cov ntaub ntawv z1-z4. Yog tias koj siv 6203 ntawm pawg Z4, tus nqi yuav tshaj 6005 ntawm pawg Z1. Outer inch 47)! Qhov no yog qhov nyuaj, thiab koj tuaj yeem them nyiaj rau qhov teeb meem no thaum koj xav yuav tsheb. Raws li rau lub xeem hom, kuv twv tsis hais ntau. Peb-quarters ntawm lub me bearings nyob hauv lub teb chaws yog concentrated hauv Cixi, Zhejiang. Koj tuaj yeem siv lub Z3 ntawm no. Koj twb tau txais nws lawm. Raws li dab tsi Havalo los yog neeg Qhov no tsis yog hais tias nws yog kiag li tsis yooj yim sua. Nws yog qhov zoo tshaj plaws kom pom nws raws li nws yog vim hais tias tus nqi ntawm cov bearings yog 3-8 lub sij hawm uas ntawm dogmat bearings, thiab tau yog tsawg heev.
Hall yog zoo li lub qhov rooj ntawm koj lub tsev. Nws yog ib lub qhov rooj rau lub tshuab kom sib txuas lus nrog cov maub los. Nws yog ob lub qhov rooj qhib qhov rooj los yog kaw qhov rooj (qhov no yog txoj cai ntawm kev txuag hluav taws xob). Tsuav tus tsav lub cev tsim kom zoo, tus maub los yog kom sib phim. Kev tsis yoojyim rau rhuav tshem lossis hlawv. Li ntawd, yog vim li cas cov Halls ntawm ntau tus neeg caij tsheb tau tam sim no hlawv dua? Thawj yog qhov teeb meem piv rau tus maub los. Tam sim no lub cev muaj zog fais fab loj dua thiab loj dua, tus maub los kuj nce siab, thiab txhua tus muaj feem kub. Tom qab ntawd qhov kev txawj ntse ntse yuav txiav tawm ntawm cov teeb liab sab nraud thaum nws pom tias cov roj kub kub ntawm kev tivthaiv hlawv, txawm nws yog lub roj teeb lossis lub tshuab. Nyob rau lub sij hawm no, nws tsis txuas ntxiv mus txuas, thiab nws nkees heev li tos. Lub sijhawm no, lub tshuab tsis txawj ntse. Nws tsis nres. Tom qab ntawd lub tshuab uas tsis nres lawm ces muab tso rau hauv ib lub tshuab hluav taws xob thiab txuas ntxiv mus txog thaum nws nres. Yog hais tias koj tshwm sim los ua qhov chaw Hall thaum koj nres, Kuv thov txim tias koj muaj kev xav tau thiab raug tua, qhov no yog ib qho tseem ceeb tshaj plaws rau kev hlawv chav Cheeb Tsam.
