Qhov txawv ntawm Permanent Magnet thiab Electromagnet
Magnetic lifters yog ntau yam khoom siv tuav cov khoom siv uas tuaj yeem siv los txav ntau yam ntawm cov hlau ferrous - los ntawm cov pob me me ntawm qhov bar lossis seem mus rau qhov loj, hnyav blocks. Hloov cov hlua khi thiab cov hlua khi nrog cov hlau nplaum nqa tuaj yeem ua kom muaj peev xwm tsim tau tag nrho, tso cai rau ib tus neeg los ' nqa' cov khoom uas xav tau ob lossis ntau tus neeg los nqa cov cuab yeej qub.
Lifting hlau nplaum tuaj yeem ua kom cov khoom tsim tau. Piv txwv li, piv txwv li ib lub voj voos kheej kheej puv kab rov tav nyob rau hauv ib qho chaw rau hauv, yog tias siv hlua los yog saw hlau es tsis txhob siv lub tshuab nqus hlau nplaum, nws yuav tsum tau nqa ib qho kawg ntawm ib sab ntawm tes kom cov hlua los yog hlua khi mus. nyob rau hauv ib feem, thiab nws tsuas yog nqa ib lub bar. Cov hlau nplaum nqa tuaj yeem txo qis los ntawm crane, nyiam mus rau qhov yuav tsum tau ua, thiab nqa ib feem tawm tsis muaj zog. Cov hlau nplaum tshem tawm qhov xav tau ntawm cov blocks thiab slings, ntxiv sijhawm txuag thiab tsis ua rau cov hlau puas.
Hom ntawmLifting Magnets
Muaj ob hom kev nqa cov hlau nplaum: cov hlau nplaum ruaj khov thiab electromagnets.
Cov hlau nplaum tas mus li, raws li lub npe qhia, siv cov khoom sib nqus mus tas li los txhim kho qhov chaw sib nqus.
Cov hlau nplaum tas mus li siv rau ntawm qhov chaw ua haujlwm feem ntau yog hloov mus rau thiab tawm siv tus tswj tuav. Lawv tuaj yeem siv los tuav cov ntaub ntawv tiaj tus nrog rau qhov sib npaug txog li 2,200 lbs. Cov khoom nqa nqa no yog 'tus kheej' thiab tuaj yeem txav mus rau qhov chaw ua haujlwm sib txawv txhua lub sijhawm hauv lub khw muag khoom, tab sis qhov tsis zoo ntawm cov hlau nplaum ruaj khov yog tias lub peev xwm nqa tau txwv.
Lub electromagnet yog hluav taws xob zoo siab thiab nyiam cov khoom siv rau cov hlau nplaum nto. Lub tshuab electromagnet siv lub zog coil qhov txhab ntawm cov tub ntxhais hlau los npaj cov khoom hauv cov khoom ferrous nyob rau hauv ib qho kev taw qhia, yog li tsim ib qho chaw sib nqus. Electromagnets feem ntau ua haujlwm ntawm qhov tam sim no ncaj qha thiab yog li xav tau lub rectifier. Tsis zoo li cov hlau nplaum tas mus li, cov hlau nplaum yuav tsum muaj lub zog tas li, uas yuav pom tau tias yog qhov tsis zoo lossis qhov zoo nyob ntawm lub hom phiaj ntawm cov hlau nplaum. Cov hluav taws xob hluav taws xob tuaj yeem ua rau muaj kev puas tsuaj thaum siv cov khoom siv hluav taws xob, txawm hais tias cov teeb meem no tuaj yeem daws tau nrog cov khoom siv hluav taws xob ntau lub hom phiaj thiab cov roj teeb thaub qab uas muaj nyob hauv khw niaj hnub no. Ntawm qhov tod tes, lub peev xwm ntawm electromagnets sib txawv ntawm cov energized tam sim no muab kev yooj yim dua rau cov neeg siv piv rau cov hlau nplaum ruaj khov.
Permanent Magnet vs. Electromagnet
Ob lub hlau nplaum ruaj khov thiab cov hlau nplaum tuaj yeem tsim tau los tsim cov ntawv sib txawv ntawm cov hlau nplaum. Thaum xaiv ib lub voj voog sib nqus, thawj qhov kev txiav txim siab yog txoj haujlwm koj xav tau cov hlau nplaum ua. Cov hlau nplaum tas mus li yog qhov muaj txiaj ntsig zoo nyob rau hauv cov xwm txheej uas hluav taws xob tsis yooj yim, hluav taws xob tshwm sim ntau zaus, lossis tsis tas yuav kho qhov sib nqus quab yuam. Electromagnets muaj txiaj ntsig zoo rau cov ntawv thov uas yuav tsum tau hloov lub zog sib nqus lossis qhov twg yuav tsum tau tswj cov chaw taws teeb. Cov hlau nplaum yuav tsum tsuas yog siv raws li qhov lawv tau npaj tseg, thiab siv cov hlau nplaum tsis raug rau ib daim ntawv thov yuav ua rau muaj kev phom sij heev lossis ua rau tuag taus.
Ntau qhov kev ua haujlwm machining yog ua rau cov ntaub ntawv hnyav thiab cov hlau nplaum ruaj khov yog xav tau rau cov ntawv thov no. Raws li ntau tus neeg siv lub khw muag khoom, qhov zoo tshaj plaws ntawm cov hlau nplaum no yog tias tsis muaj hluav taws xob sib txuas.
Cov hlau nplaum ruaj khov muaj qhov 330-10, 000- phaus nqa lub peev xwm, thiab lub voj voog sib nqus tuaj yeem qhib lossis kaw nrog ib qho tig ntawm tus kov. Cov hlau nplaum feem ntau haum nrog kev ruaj ntseg xauv kom ntseeg tau tias cov hlau nplaum tsis tuaj yeem raug txiav tawm thaum lub sijhawm nqa. Cov pab pawg hlau nplaum tuaj yeem siv rau cov khoom hnyav thiab ntev uas tsis tuaj yeem ua haujlwm los ntawm ib qho hlau nplaum.
Tsis tas li ntawd, ntau zaus cov khoom uas yuav tsum tau ua yog nyias nyias (0.25 ntiv tes los yog finer) thiab tau kos los ntawm lub pas dej ua ke ntawm qhov zoo sib xws. Cov hlau nplaum tas mus li tsis haum rau kev nqa cov khoom los ntawm ib pawg ib zaug. Cov hlau nplaum tas mus li, txawm tias muaj kev ntseeg siab heev thaum siv kom raug, tsis tuaj yeem hloov lub zog sib nqus. Hauv qhov no, electromagnets tso cai rau tus neeg teb xov tooj los tswj lub zog ntawm cov hlau nplaum los ntawm kev tswj cov hluav taws xob sib txawv thiab xaiv ib qho los ntawm ib pawg ntawm cov khoom. Self-muaj solenoids yog cov hlau nplaum uas muaj nqi tshaj plaws rau ib chav tsev ntawm kev nqa nqa, uas tuaj yeem txuas mus rau 10,500 lbs.
Cov hlau nplaum uas muaj roj teeb muaj txiaj ntsig zoo, lawv siv cov roj teeb uas muaj gel rau lawv tus kheej kom muaj peev xwm nqa tau, thiab tuaj yeem tuav cov khoom tiaj tus, puag ncig, thiab cov khoom zoo li. Cov hlau nplaum uas siv los ntawm cov roj teeb tuaj yeem rov ua qhov kev nqa nqa, muab lub peev xwm nqa ntau yam tsis muaj lub zog sab nraud.
Pib nrog Magnetic Crane
Lifting hlau nplaum, txawm tias hluav taws xob lossis mus tas li, muaj qhov ntsuas ntsuas ntawm daim ntawv teev npe. Lub peev xwm no muaj feem xyuam rau qee qhov tuab. Yog tias cov hlau nplaum siv rau cov khoom siv nrog lub thickness me dua li tus nqi ntsuas, qhov ntsuas qhov peev xwm yuav raug txo. Txhawm rau ua kom muaj peev xwm nqa tau, cov hlau nplaum nqa tuaj yeem ntsia tau rau hauv pawg ntawm cov nqaj nqa nqa. Thaum siv ib pawg hlau nplaum los nqa lub nra, cov hlau nplaum yuav tsum sib npaug sib npaug kom sib faib tag nrho cov khoom thauj. Cov ntaub ntawv zoo li sag yam tsis muaj kev txhawb nqa, yog li cov hlau nplaum yuav tsum muaj qhov loj me kom txhawb nqa lub nra. Thaum lub load yog nqa thiab thim rov qab, kev saib xyuas yuav tsum tau ua kom lub peev xwm ntawm cov hlau nplaum poob mus txog li 1/4 ntawm tus nqi teev rau ntawm daim ntawv teev npe. Tsis tas li ntawd, cov khoom zoo li plam thaum raug shear, yog li yuav tsum tau saib xyuas hauv cov ntawv thov no.
Nyob rau hauv rooj plaub uas cov hlau nplaum ua haujlwm ntawm DC, ib qho kev sib koom ua ke AC-DC rectifier thiab hlau nplaum maub los yuav tsum tau muab tso rau ntawm lub crane, uas hloov lub zog crane ntawm AC mus rau DC thiab hloov cov hluav taws xob sib nqus ntawm / tawm.
Cov chaw taws teeb ua haujlwm nqa cov hlau nplaum tuaj yeem tswj tau los ntawmcrane cab, los yog ntawm ib tug pendant hloov los yog tej thaj chaw deb transmitter. Cov tshuab no yog siv los ua ib daim ntawv los yog ntau daim ntawv, txawm nyob rau hauv qhov chaw cia khoom, lub tsheb thauj khoom, lossis txiav lub rooj thauj khoom thiab tshem tawm. Lub tshuab hluav taws xob kuj tau nruab nrog lub roj teeb ntxiv thaum muaj hluav taws xob poob.
