Muaj ob qhov xwm txheej rau kev sib khi ntawm lub tshuab nqus tsev. Ib qho yog tias lub foob cais ib lub thawv ntim nrog cov kua nruab nrab ntawm lub tshuab nqus tsev sab nraud. Hauv qhov no, lub luag haujlwm tseem ceeb ntawm lub foob yog txhawm rau tiv thaiv cov kua nruab nrab los ntawm kev nkag mus rau hauv qhov chaw nqus. Lwm qhov xwm txheej yog tias lub foob cais lub tshuab nqus tsev sab hauv los ntawm cov kab noj hniav sab nraud, thiab nws txoj haujlwm yog los tswj lub tshuab nqus tsev uas yuav tsum tau ua. Qhov teeb meem no yog qhov nyuaj dua, vim tias txawm tias me ntsis to ntawm cov pa nruab nrab ib puag ncig rau hauv lub tshuab nqus tsev yuav txo nws lub tshuab nqus tsev. Yog tias cov roj corrosive xau hauv, cov khoom siv lub tshuab nqus tsev yuav puas. Feem ntau, qhov ntsuas ntawm lub tshuab nqus tsev thiab kev huv ntawm lub tshuab nqus tsev muaj qhov txiav txim siab ntawm qhov zoo ntawm ntau yam txheej txheem ua raws li lub tshuab nqus tsev. Lub tshuab foob siv hauv lub tshuab nqus tsev tsis muaj qhov tshwj xeeb hauv nws cov qauv. Rau thawj rooj plaub uas tau hais los saum toj no, ib qho hlau bellows hom ib leeg-kawg tshuab foob nrog zoo airtightness feem ntau yog siv. Nyob rau hauv rooj plaub thib ob, ob lub ntsej muag kawg lub ntsej muag tshuab foob yog siv. Yog tias siv lub ntsej muag kawg nkaus, yuav tsum muaj teeb meem uas lub ntsej muag lub ntsej muag tsis tuaj yeem lubricated.
Feem ntau, nws yog ib qho nyuaj rau cov tib neeg kom paub qhov txawv ntawm cov tshuab foob thiab hydraulic seals, thiab lawv feem ntau xav tias lawv yog tib yam.
Lub ntsiab lus ntawm mechanical seals thiab hydraulic seals:
Mechanical seals yog ib qho ntawm cov cuab yeej siv tshuab yooj yim nrog precision thiab complex qauv. Lawv yog cov khoom tseem ceeb ntawm ntau lub twj tso kua mis, cov tshuaj tiv thaiv hluavtaws kettles, turbo compressors, submersible motors thiab lwm yam khoom siv. Nws sealing kev ua tau zoo thiab kev pab cuam lub neej nyob ntawm ntau yam, xws li hom xaiv, tshuab raug, raug installation thiab siv, thiab lwm yam.
Hydraulic seals muaj kev xav tau siab thiab xav tau qee qhov kev sib tw ntawm qhov sib koom ua ke. Cov khoom sib khi feem ntau yog cov roj hmab, thiab cov nyhuv sealing tiav los ntawm lub zos deformation ntawm lub foob.
Classification ntawm mechanical seals thiab hydraulic seals
Mechanical foob qauv: cartridge foob series, lub teeb mechanical foob series, hnyav mechanical foob series, thiab lwm yam.
Hydraulic seals: di ncauj ntsaws ruaj ruaj, V-shaped ntsaws ruaj ruaj, U-puab ntsaws ruaj ruaj, Y-zoo li cov ntsaws ruaj ruaj, YX-zoo li cov ntsaws ruaj ruaj, thiab hydraulic thooj voos kheej kheej. Cov khoom siv sib xyaw ua ke feem ntau yog cov hlua khi hlua khi, cov hlua khi hlua khi thiab ster seals.
Xaiv lub foob
Thaum yuav cov ntsaws ruaj ruaj rau kev saib xyuas, feem ntau cov neeg siv yuav yuav lawv raws li qhov loj thiab xim ntawm cov qauv. Qhov no tsuas yog nce qhov nyuaj ntawm kev yuav khoom thiab tej zaum yuav tsis tas yuav xaiv cov khoom tsim nyog. Cov txheej txheem hauv qab no raug pom zoo los txhim kho qhov tseeb ntawm kev yuav khoom ntawm cov ntsaws ruaj ruaj:
1. Cov kev taw qhia ntawm kev txav mus los - ua ntej txiav txim siab ntawm kev txav ntawm qhov chaw ntawm lub foob, xws li reciprocating, rotating, kauv lossis tsau.
2. Kev sib khi ua kom pom tseeb-piv txwv li, txiav txim siab seb lub ntsiab lus tseem ceeb yog qhov khi hlua khi nrog lub taub sab hauv lossis lub piston foob nrog lub taub sab nraud.
3. Qib ntsuas kub-sib sab laj thawj cov lus qhia ua haujlwm ntawm lub tshuab lossis ntsuas qhov ua haujlwm kub raws li qhov chaw ua haujlwm tiag tiag los txiav txim siab cov ntaub ntawv xav tau. Rau cov lus piav qhia ntawm qhov ntsuas kub, thov xa mus rau cov ntawv hauv qab no rau cov neeg siv khoom tsim khoom.
4. Qhov loj me-feem ntau cov neeg siv yuav xaiv cov qauv qub uas tau siv, tab sis tom qab siv lub sijhawm, qhov loj ntawm lub foob yuav cuam tshuam zoo heev los ntawm cov khoom xws li kub, siab thiab hnav. Kev xaiv raws li tus qauv tsuas yog siv tau raws li kev siv, Ib txoj hauv kev zoo dua yog ntsuas qhov loj ntawm cov hlau zawj qhov twg lub foob nyob, qhov tseeb yuav siab dua.
5. Cov qib siab-xa mus rau cov ntaub ntawv cuam tshuam los ntawm cov lus qhia kev siv tshuab qub, lossis ntsuas qhov ua haujlwm siab los ntawm kev soj ntsuam qhov hardness thiab cov qauv ntawm thawj lub foob. Rau cov lus piav qhia qib siab, thov xa mus rau cov ntawv hauv qab no rau cov neeg siv khoom tsim khoom.
