Hauv Tuam Tshoj thaum ub, tib neeg khi lub lauj kaub av nplaum nrog ib kawg ntawm txoj hlua, tuav lwm qhov kawg ntawm txoj hlua, tig lub lauj kaub, tsim kom muaj lub zog centrifugal kom nyem tawm cov zib ntab rau hauv lub lauj kaub, qhov no yog daim ntawv thov thaum ntxov ntawm lub hauv paus ntsiab lus ntawm centrifugal. sib cais.
Muaj cov centrifuges tau yug los hauv Tebchaws Europe. Piv txwv li, nyob rau hauv nruab nrab ntawm xyoo pua puv 19, peb ko taw centrifuges rau textile lub cev qhuav dej thiab sab saum toj kawg ntawm centrifuges rau kev cais cov kua qab zib hauv qab zib hauv qab zib mills pom kev ua tiav. Qhov kev tawm tswv yim thaum ntxov no yog kev ua haujlwm ntu thiab phau ntawv slagging.
Vim tias kev txhim kho ntawm cov tshuab tsis ua haujlwm, kev ua haujlwm tsis tu ncua centrifuges tau tshwm sim nyob rau xyoo 1930, thiab cov sijhawm ua haujlwm nruab nrab centrifuges tseem raug tsim vim qhov tseeb ntawm kev tswj tsis siv neeg.
Kev lag luam centrifuges tuaj yeem muab faib ua lim dej centrifuges, kev sib xyaw av centrifuges thiab cais tawm raws li cov qauv thiab cov tseev kom muaj sib cais.
Lub centrifuge muaj lub tog raj kheej uas tig ncig nws lub axis ntawm kev kub ceev, hu ua lub nruas, thiab feem ntau yog tsav los ntawm lub tshuab hluav taws xob. Tom qab ncua kev kawm ntawv (lossis emulsion) ntxiv rau lub nruas, nws tau nrawm nrawm rau tig ntawm tib lub nrawm ntawm lub nruas, thiab cov khoom sib cais tau sib cais raws li kev ua ntawm centrifugal quab yuam thiab tawm mus sib cais. Feem ntau, qhov ntau dua lub nruas ceev, qhov sib cais cov nyhuv zoo dua.
Lub tshuab centrifugal separator muaj ob txoj haujlwm: centrifugal lim thiab centrifugal sedimentation. Centrifugal filtration yog lub zog centrifugal siab uas tsim los ntawm kev ncua hauv lub zog centrifugal teb, uas ua haujlwm ntawm lub nruab nrab lim, kom cov kua kis tau los ntawm lub nruab nrab lim thiab dhau los ua cov lim dej, thaum cov khoom tawg tau daig rau saum nplaim lim nruab nrab kom ua tiav cov kua-sib cais; centrifugal sedimentation yog siv Lub hauv paus ntsiab lus tias cov feem ntawm kev ncua (lossis emulsion) nrog ntau qhov sib txawv tau txiav txim siab nrawm nrawm hauv lub zog centrifugal kom ua tiav cov kua-ua tau (lossis kua-kua) cais sib cais.
Kuj tseem muaj ntau hom kev cais tawm rau kev tsom xam, uas tuaj yeem ua cov kua kom paub meej thiab ua cov khoom tawg, lossis cov kua sib cais. Hom kev sib cais no muaj cov qauv sib txawv uas ua haujlwm hauv kev ua haujlwm siab, lub tshuab nqus tsev, thiab qhov chaw ua haujlwm txias.
Qhov ntsuas tseem ceeb rau ntsuas qhov sib cais ua tau zoo ntawm cov centrifuge yog qhov sib cais sib cais. Nws sawv cev qhov sib piv ntawm lub zog centrifugal mus rau qhov sib tsoo ntawm cov khoom kom raug sib cais hauv lub nruas. Qhov loj dua ntawm qhov sib cais, qhov sib cais sai dua thiab qhov zoo dua qhov sib cais. Qhov sib cais ntawm cov tshuab centrifugal separator feem ntau yog 100 txog 20000, qhov sib cais sib cais ntawm ultra-tshaj tawm cov raj cais tau ntau npaum li 62,000, thiab qhov sib cais ntawm ultra-tshaj tawm cov sib cais rau kev tsom xam yog siab txog 610,000. Lwm qhov ntxiv uas txiav txim siab xyuas cov kev ua haujlwm ntawm centrifugal separator yog thaj chaw ua haujlwm ntawm lub nruas. Thaj chaw ua haujlwm loj kuj tseem muaj peev xwm tsim khoom loj.
Lim centrifuges thiab cov kev ua kom cov centrifuges tsuas yog vam khom nce ntawm txoj kab uas hla ntawm lub nruas kom nthuav dav kev ua haujlwm ntawm qhov ncig ntawm ncig ntawm lub nruas; ntxiv rau sab nrauv phab ntsa ntawm lub nruas, lub cais tawm kuj tseem muaj cov chaw ua haujlwm ntxiv, xws li lub disc thiab chav ntawm cov disc separator Sab hauv lub tog raj kheej ntawm cov khoom sib cais ua rau muaj kev cuam tshuam ntau qhov chaw ua haujlwm nto.
Tsis tas li ntawd, ntau cov ntsiab lus sib cais ntawm cov khoom sib txawv hauv kev ncua, qhov nyuaj tshaj nws yog qhov nyuaj, thiab cov nplua zoo coj hauv cov lim dej lossis cov kua cais kom ntau ntxiv. Hauv qhov no, lub centrifuge xav tau kev sib cais ntau dua los ua kom zoo sib cais; Thaum cov kua viscosity siab, qhov kev sib cais nrawm qeeb; qhov sib txawv ntawm qhov sib txawv ntawm txhua feem ntawm kev ncua lossis emulsion yog loj, uas tau txais txiaj ntsig los ntawm kev ua kom lub zog centrifugal, thaum qhov kev tshem tawm centrifugal lim tsis xav tau qhov ntom sib txawv ntawm txhua feem.
Kev xaiv ntawm centrifugal separator yuav tsum ua raws qhov loj me thiab kev kub siab ntawm cov khoom sib txawv hauv qhov ncua (lossis emulsion), qhov sib txawv ntawm qhov sib txawv ntawm cov khoom thiab cov kua (lossis ob lub kua), cov viscosity ntawm cov kua, cov yam ntxwv ntawm lim residue (los yog sediment), thiab cov kev sib cais yuav tsum muaj kev soj ntsuam tau ua tiav kom tau raws li qhov yuav tsum tau ua rau cov dej noo ntawm lub lim dej (lim av) thiab qhov meej ntawm lim dej (cais kua), thiab hom twg ntawm centrifugal separator yog xaiv thawj zaug. Tom qab ntawd raws li cov txheej txheem ua thiab cov automation uas yuav tsum tau ua ntawm kev ua haujlwm, hom thiab qhov tshwj xeeb ntawm lub centrifuge raug txiav txim siab, thiab thaum kawg kuaj xyuas los ntawm qhov ntsuas tiag tiag.
Feem ntau, rau kev ncua uas muaj cov khoom ntau tshaj 0.01 hli hauv qhov loj me, lim dej centrifuges tuaj yeem siv; rau kev ncua nrog cov qhov me me lossis cov kev hloov kho tsis tuaj yeem, txo kev ua kom loog centrifuges yuav tsum siv; rau cov kev ncua nrog cov khib nyiab uas tsis muaj cov ntsiab lus me me, thiab thaum ua kom pom tseeb ntawm cov kua, yuav tsum siv tus cais tawm.
Kev txhim kho yav tom ntej ntawm cov centrifugal separator yuav ua kom muaj zog ntawm kev sib cais kev ua tau zoo, txhim kho cov txheej txheem loj centrifugal separators, txhim kho slag paug mechanism, nce tshwj xeeb thiab sib xyaw nruas centrifuges, ntxiv dag zog rau kev sib cais kev tshawb fawb tshawb fawb thiab kawm txog kev ua haujlwm tswj kev siv tshuab kev sib cais centrifugal. cov txheej txheem.
Ua kom muaj zog ntawm kev sib cais muaj xws li nce kev sib hloov ceev ntawm lub nruas tig; ntxiv cov tsav tsheb tshiab thaum lub sijhawm ua haujlwm centrifugal sib cais cov txheej txheem; leeb lub slag thawb nrawm; nce qhov ntev ntawm lub nruas tig kom txuas lub sijhawm ntawm centrifugal sedimentation thiab sib cais. Kev tsim cov tshuab loj loj centrifugal separator feem ntau yog ua kom lub qhov loj ntawm lub nruas thiab kev siv lub nruas ob npaug los txhawm rau txhim kho kev ua ntau ntxiv kom cov cuab yeej siv peev, siv zog thiab txij nkawm nqi rau kev ua cov ntim ntim ntawm cov khoom siv txo. Hais txog kev tshawb fawb theoretical, nws tsuas yog kawm txog kev ua dej ntws ua kom haum rau hauv lub nruas thiab kev tsim cov txheej txheem ntawm cov lim dej seem, thiab kawm txog cov tswv yim kev suav ntawm kev sib cais tsawg kawg thiab kev ua kom muaj peev xwm.
