Cov lim dej yog cov pob txha ntawm cov kua dej huv thiab tau siv dav hauv ntau lub lag luam, suav nrog kev tsim khoom thiab kev kho mob. Txhawm rau kom ua tiav lawv cov txiaj ntsig, nws yog ib qho tseem ceeb kom paub cov tswv yim xaiv cov hom phiaj, qhia meej cov lus nug, thiab tsim cov txheej txheem ua tiav. Cov lus qhia no ua kom yooj yim rau qhov nyuaj thiab muab tswv yim rau koj rau kev pom niaj hnub xav tau.
Cov ntsiab lus
1. Kev txawj ntse lim caij xaiv lub tswv yim
2. Cov ntsiab lus siv tau thiab cov kev coj ua zoo tshaj plaws
3. Cov kev cia siab yav tom ntej rau cov ntawv thov lim
4. Cov lus teb rau cov lus nug tseem ceeb
1. Cov tswv yim xaiv ntse rau cov ntsiab lus lim
1.1 Nyob rau hauv- tsom xam qhov tob ntawm cov kua thiab cov pa paug
Thawj kauj ruam hauv cov txheej txheem xaiv yog txhawm rau txheeb xyuas qhov "tus yam ntxwv" ntawm cov kua dej: Puas yog kua nplaum, roj, lossis cov tshuaj nplua nuj nyob hauv cov tshuaj? Qhov kub thiab tshuaj muaj zog ntawm cov kua dej tsis tuaj yeem raug ignored - cov lim cov ntsiab lus uas yuav tsum tau ua rau cov kua roj thiab cov kua qaub acidic sib txawv heev.
Cov kab mob sib kis tsis zoo ib yam. Cov nroj tsuag ua zaub mov tej zaum yuav tau cuam tshuam nrog "cov pa phem" xws li cov poov xab thiab cov kab mob, thaum qhov chaw pom ntawm qhov chaw tsim kho tsom mus rau cuam tshuam "cov khoom tsis zoo" xws li xuab zeb, pob zeb, thiab khib nyiab. Nws raug nquahu kom siv cov cuab yeej xws li laser diffraction analyzers kom raug daim ntawv qhia cov ntaub ntawv loj me me kom phim cov peev xwm pom ntawm lub lim dej thiab ua rau kev xaiv ntau dua.
Kev lim dej tsis yog yooj yim li "cov kua dej huv", tab sis kuj yuav tsum ua kom tau raws li cov qauv kev lag luam. Hauv kev lag luam tshuaj, kev pom tseeb, uas yog, qhov ua tau zoo ntawm kev tshem tawm cov khoom saum toj no qee qhov teeb meem loj txog 99.9%, uas yog qhov yuav tsum tau ua kom nruj; thaum nyob rau hauv industrial circulating dej systems, nominal filtration, uas yog, tshem tawm feem ntau ntawm cov khoom ntawm lub hom phiaj particle loj, feem ntau ua tau raws li cov kev xav tau.
Flow rate kuj tseem ceeb heev. Yog tias cov khoom lim tau nquag thaiv thaum lub sijhawm xav tau siab tshaj plaws, nws poob nws qhov tseem ceeb ntawm daim ntawv thov. Nws yog ib qho tsim nyog los xam cov nkas loos ib feeb txaus tus nqi thiab siab poob siab ntev. Yog tias cov khoom lim loj dhau lawm, nws yuav ua rau qhov chaw pov tseg; yog tias nws me dhau lawm, nws yuav ua rau kev ua haujlwm tsis zoo ntawm qhov system.
1.3 Lim yam hom thiab cov qauv kev hloov kho
Cov khoom lim tsis yog homogeneous cov khoom, thiab ntau hom muaj lawv tus kheej zoo:
- Pleated membrane lim caij: Nrog rau kev tsim pleated, thaj tsam loj ntawm cov txheej lim tau muab tso rau hauv lub plhaub nqaim, uas yog qhov kev xaiv zoo tshaj plaws rau chav kuaj- qib purity yuav tsum.
- Lub hnab lim khoom: Cov nqi ua tau zoo, tsim nyog rau cov dej ntws loj, qis - qhov tseeb pom qhov xwm txheej, tuaj yeem cuam tshuam ntau qhov tsis huv.
- Sib sib zog nqus lim caij: Siv ntau txheej txheej ntawm cov xov xwm los ntes cov khoom ntawm ntau qhov sib txawv tuaj yeem tsim kom muaj "kev tiv thaiv net" rau cov khoom siv qis qis.
Thaum xaiv, nws yog ib qho tsim nyog yuav tsum tau muab cov kev txwv qhov system. Compact pleated lim ntsiab yog haum rau scenarios nrog txwv qhov chaw, thaum khovhnab lim ntsiabtuaj yeem tiv nrog siab - ib puag ncig impurity.
1.4 System compatibility pov thawj
Cov ntsiab lus lim yuav tsum "sib haum" nrog lub vaj tsev. Ua tib zoo xyuas qhov loj me thiab sealing mechanism kom tsis txhob muaj kev pheej hmoo ntawm kev tawg. Cov khoom siv sib xws yog cov kab hauv qab yuav tsum tau ua - fluoropolymer lim cov ntsiab lus yog cov tshuaj tiv thaiv, thiab cov khoom lim cellulose haum rau cov kua dej.
Rau aseptic daim ntawv thov scenarios, nws tseem yuav tsum tau paub meej tias seb lub lim caij tuaj yeem tiv taus kom tsis muaj menyuam thiab yuav tsis degrade thaum lub sijhawm ua haujlwm.
2. Cov ntsiab lus siv tau thiab cov kev coj ua zoo tshaj plaws
Kev teeb tsa
- Kev ruaj ntseg foob: Hauv kev siv huv huv, siv cov khoom noj- qib roj nplua nyeem rau O-rings; zam roj av- raws li cov khoom lag luam los tiv thaiv cov kua dej paug.
- Flow direction control: Feem ntau cov ntsiab lus lim tau cim nrog "inlet" thiab "qhov hluav taws xob". Rov qab ntws yuav ua rau cov khoom lim dej puas. Them mloog mus rau lub xub cim thaum lub sij hawm installation.
Kev saib xyuas thiab kev saib xyuas
- Cov ntaub ntawv kaw lus siab: txuas ntxiv taug qab cov kev hloov pauv hauv kev poob siab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua ntej.
- Ua ntej- pom kev tiv thaiv: Nruab ib qho ntxhib- cuam tshuam ua ntej- lim (xws li lub hnab lim lub ntsiab) txhawm rau txuas ntxiv lub neej kev pabcuam siab -cov ntsiab lus lim.
- Cov txheej txheem ntxuav: Rau cov khoom lim rov qab siv tau (xws li qee cov lim dej sib sib zog nqus), ua raws li kev tu lub voj voog - kev tu ntau dhau tuaj yeem ua rau cov khoom lim tau yooj yim puas.
Tej teeb meem daws teeb meem
- Cov teeb meem dej xau: Ua ntej nruj qhov kev sib txuas thiab hloov lub nplhaib O- puas lawm; yog tias cov dej ntws mus ntxiv, xyuas seb lub tsev puas deformed.
- Cov teeb meem pom tsis zoo: Paub meej tias seb qhov lim cov khoom puas haum raws li qhov yuav tsum tau ua. Yog hais tias cov khoom "kua hauv lub vas", lub lim dej yuav raug xaiv tsis raug lossis puas.
- Teeb meem poob siab: Ntxuav lossis hloov lub lim ua ntej - kom ntseeg tau tias lub kaw lus ntws tsis dhau lub lim lim load txwv.
3. Kev cia siab yav tom ntej rau daim ntawv thov lim
Raws li kev lag luam tsim, lim cov ntsiab lus kuj yuav tsum tau hloov kho dua tshiab. Kev xyuam xim rau cov qauv no tuaj yeem ua rau koj qhov system pom "txog hnub tim":
- Ntse filter element:Ua tau -hauv sensor, tiag tiag- lub sij hawm tawm tswv yim ntawm cov ntaub ntawv siab, ntws thiab cov pa phem, los pab kev ua haujlwm thiab kev saib xyuas.
- Sustainable lim media:Siv cov khoom siv biodegradable lossis recyclable los txo cov kev cuam tshuam ib puag ncig thiab ua tau raws li cov kev xav tau ntawm kev loj hlob ntsuab.
Kev paub txog cov ntsiab lus ntawm kev xaiv, qhia meej cov lus nug, thiab ua kom raug lawv tuaj yeem hloov cov ntsiab lus lim los ntawm "cov khoom qub" mus rau "cov cuab yeej cuab tam" - txhim kho kev tsim khoom, ua kom muaj kev ua raws cai, thiab tiv thaiv cov txiaj ntsig ntawm cov tuam txhab. Txawm hais tias koj tab tom lim dej tshuaj lossis kho cov dej khib nyiab, phau ntawv qhia no tuaj yeem pab koj "ntse pom, ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog".
4. Cov lus nug tseem ceeb
Dab tsi yog qhov lim dej?
Cov khoom lim dej yog ib qho kev ua haujlwm ntawm nws tus kheej "filter capsule" nrog cov xov xwm lim hauv. Thaum cov kua dej dhau los, cov kab mob kis tau raug cuam tshuam. Nws cov qauv cylindrical tuaj yeem ntsia tau yooj yim hauv cov vaj tsev tus qauv, ua kom yooj yim rau kev teeb tsa.
Yuav ua li cas xa cov lim dej?
Kev npaj vaj tsev: Ntxuav lub vaj tsev thiab tshem tawm cov impurities uas yuav nyob ib ncig ntawm lub lim dej.
Kev teeb tsa: Ntxig lub lim kom ruaj khov thiab xyuas kom meej tias O-ntiv nplhaib haum rau qhov chaw. Thaum txhim kho lub membrane lim caij, tsis txhob dhau -ntxo nws kom tsis txhob ua rau cov khoom lim puas.
Flow test: Khiav cov kua dej ntawm qhov pom zoo txaus txaus thiab saib xyuas lub siab. Kev nce siab sai sai yuav qhia tau tias kev teeb tsa tsis raug lossis ua ntej -clogging ntawm lub lim lim.
Dab tsi yog cov yam ntxwv ntawm "zoo tagnrho lim caij"?
Muaj peb yam tseem ceeb rau kev sib npaug:
Qhov tseeb: Ua raws li koj qhov kev xav tau tshem tawm particle.
Efficiency: Tsis tshua muaj siab poob thiab siab av tuav peev.
Durability: Resistant mus rau chemical thiab thermal degradation nyob rau hauv cov dej teev ib puag ncig.
Yuav txhais li cas lim qhov tseeb?
Qhov no yog "daim ntawv qhia kev ua tau zoo" ntawm cov khoom lim. "Nominal raug" yog cov lus qhia dav dav; "qhov tseeb tseeb" yog qhov tseeb dua thiab yuav tsum tau-muaj rau kev lag luam tswj hwm. Nws raug nquahu kom hla - tshawb xyuas thib peb- cov ntaub ntawv xeem thib peb kom ntseeg tau tias muaj tseeb.
Thaum twg los hloov lub lim dej?
Nrhiav ob lub cim tseem ceeb:
Kev hloov hauv siab poob: Ib qho 20-25% nce hauv siab poob piv rau lub hauv paus, saib xyuas los ntawm lub ntsuas siab, qhia tau hais tias cov khoom lim lim.
Cov kua dej zoo: Ua kom muaj cov pa paug ntau ntxiv hauv cov qauv lim, kuaj pom nrog lub ntsuas particle lossis turbidity meter.
