Cov nroj tsuag txuag nyiaj, tiv thaiv ib puag ncig, thiab ua kom cov neeg ua haujlwm muaj kev nyab xeeb thaum lawv lub tshuab twj tso kua mis tsis xau. Mechanical seals yog ib qho tseem ceeb heev rau kev ua tiav lub hom phiaj ntawm xoom xau vim tias lawv txav mus thiab ruaj twj tso kua mis los ntawm kev kov ib leeg. Thaum nws los txog rau cov qauv kev daws teeb meem, covJohn Crane 502 mechanical foob yog tus qauv kub rau roj hmab hauv qab tsim. Nws muaj tus kheej -aligning nta uas kho cov teeb meem nrog cov ncej misalignment thiab kawg ua si. Qhov no tau sim-thiab- thev naus laus zis tiag tiag pab OEM tsim, pab pawg txhawb nqa, thiab cov tswv lag luam txiav tawm lub sijhawm poob thaum tseem ua tau raws li tsoomfwv cov cai nruj hauv kev tsim hluav taws xob, kev ua tshuaj lom neeg, thiab kev kho dej.
Nkag siab txog Mechanical Seals thiab lawv cov txiaj ntsig hauv Leak -Pub Pump Systems
Mechanical seals khaws cov txheej txheem cov kua dej los ntawm kev txav mus rau hauv cov twj tso kua mis, compressors, thiab regulators. Lawv ua qhov no los ntawm kev ua raws li cov ntsaws ruaj ruaj. Niaj hnub nimno mechanical seals ua ib qho zoo meej foob los ntawm nias ua ke kom meej -lapped ntsej muag nrog hydraulic thiab mechanical rog. Kev ntim khoom tso cai rau kev tswj cov dej ntws tawm.
Yog vim li cas Leak-Kev Ua Haujlwm Dawb Tsis Muaj Teeb Meem hauv Ib puag ncig kev lag luam
Muaj ntau thiab ntau lub siab rau cov txheej txheem kev lag luam kom tshem tawm cov pa phem tawm mus thiab tso tseg cov khoom txaus ntshai. Lub tuam txhab tshuaj nrog ib lub twj tso kua mis tsuas tuaj yeem poob ntau txhiab nyiaj ntawm cov khoom lag luam txhua xyoo, raug nplua los ntawm tsoomfwv, thiab ua rau ib puag ncig puas tsuaj. Cov teeb meem no tuaj yeem daws tau los ntawm kev siv tshuab sealing tshuab, uas ua kom lub nplhaib sib hloov ntawm lub twj tso kua mis hauv kev sib cuag nrog lub nplhaib ruaj ruaj hauv lub twj tso kua mis. Qhov chaw me me ntawm cov chaw tiaj tus no -feem ntau ntsuas hauv micrometers- tsuas yog cia ib zaj duab xis nyias ntawm lubrication muaj nyob, uas txwv tsis pub cov kua dej ntau los ntawm kev xau.
Cov txiaj ntsig tseem ceeb ntawm Advanced Mechanical Sealing Solutions
High -cov khoom siv kho tshuab zoo txhawb kev ua haujlwm ntau txoj hauv kev. Cov ntsaws ruaj ruaj tiv thaiv impurities thiab kua poob, txuas lub neej ntawm cov cuab yeej thiab txo cov kabmob thiab cov ncej puas. Hloov cov ntsaws ruaj ruaj txhua ob peb lub hlis tsis yog txhua xyoo kom txuag tau cov nqi kho. Qhov no yog qhov tseeb tshwj xeeb tshaj yog thaum cov elastomeric bellows tsim tshem tawm cov ntsiab lus tsis ua haujlwm xws li cov ntawv thaiv thiab cov rusty springs.Packing glands xav tau cov dej txias tsis tu ncua, hos cov tshuab seals haus dej tsawg dua.
