Koj puas paub tias lub tshuab foob yog dab tsi?

Mechanical seal yog hais txog cov cuab yeej tsim los ntawm yam tsawg kawg ib khub ntawm qhov kawg ntawm lub ntsej muag perpendicular mus rau lub axis ntawm kev sib hloov nyob rau hauv qhov kev txiav txim ntawm cov kua siab thiab elastic (los yog sib nqus quab yuam) ntawm cov nyiaj them nyiaj mechanism thiab kev koom tes ntawm cov koom haum seals kom muaj kev sib raug zoo thiab cov txheeb ze. zawv zawg los tiv thaiv cov kua dej. Lub elastic loading mechanism thiab auxiliary foob yog cov neeg kho tshuab ntsaws ruaj ruaj ntawm hlau bellows, uas peb hu ua hlau bellows seals. Nyob rau hauv lub teeb sealing, kuj tseem muaj kev siv cov roj hmab hauv qab ua cov ntsaws ruaj ruaj, roj hmab hauv qab elasticity yog txwv, feem ntau yuav tsum tau ntxiv nrog cov springs kom tau raws li lub caij nplooj ntoos hlav loading. "Mechanical seal" feem ntau hu ua "machine seal".

Mechanical foob yog qhov tseem ceeb tshaj plaws ntawm txoj kev sib khi hauv cov twj centrifugal, reactors, agitators thiab lwm yam khoom siv. Mechanical foob, tseem hu ua lub ntsej muag foob, tau txhais nyob rau hauv cov qauv hauv lub tebchaws raws li hauv qab no: "Ib qho cuab yeej los tiv thaiv cov kua dej los ntawm yam tsawg kawg ib khub ntawm qhov kawg ntawm lub ntsej muag perpendicular mus rau lub axis ntawm kev sib hloov nyob rau hauv qhov kev txiav txim ntawm cov kua siab thiab elastic quab yuam. (los yog sib nqus quab yuam) ntawm kev them nyiaj mechanism thiab kev koom tes ntawm cov koom haum pabcuam. "

Mechanical foob yog ib qho khoom siv foob rau kev sib hloov tshuab. Piv txwv li xws li centrifugal twj, centrifuges, reactors thiab compressors. Txij li thaum lub propeller ncej khiav los ntawm cov khoom siv sab hauv thiab sab nraud, nyob rau hauv txoj kev no, muaj qhov sib txawv ntawm cov ncej thiab cov khoom siv, los ntawm qhov nruab nrab ntawm cov khoom siv tawm sab nraud, yog tias lub siab hauv cov cuab yeej qis dua atmospheric. siab, cov cua nkag mus rau hauv cov khoom siv, yog li yuav tsum muaj cov khoom siv foob pob hluav taws kom tiv thaiv kom tsis txhob tawg. Muaj ntau hom ntsaws ruaj ruaj, vim tias cov ntsaws ruaj ruaj muaj qhov zoo ntawm qhov tsis tshua muaj dej thiab lub neej ntev, yog li lub ntiaj teb cov tshuab ntsaws ruaj ruaj yog cov txheej txheem tseem ceeb tshaj plaws hauv cov khoom siv no.
