Hauv kev lag luam niaj hnub no, qhov tseem ceeb ntawm kev siv tshuab sealing yog qhov tseeb ntawm nws tus kheej. Ntawm lawv, Y-zoo li lub foob yog ib qho kev sib khi ua ke, nws qhov kev ua tau zoo yog cuam tshuam ncaj qha rau kev nyab xeeb thiab ruaj khov ntawm cov cuab yeej siv tshuab. Hauv daim ntawv no, peb yuav tshawb nrhiav cov qauv tsim tshiab thiab xaiv cov khoom siv ntawm Y-zoo li cov ntsaws ruaj ruaj, muab cov ntaub ntawv siv rau kev nce qib hauv cov haujlwm muaj feem xyuam.
Kev tsim tshiab ntawm Y-puab foob
Kev tsim kho kom zoo
Cov tsoos Y-shaped foob muaj cov qauv yooj yim, uas yog tsim los ntawm daim di ncauj tseem ceeb thiab daim di ncauj thib ob. Txhawm rau txhim kho qhov kev sib khi ua tau zoo, peb thov kom muaj Y-zoo li lub foob nrog 'qhov chaw kaw' tsim. Qhov kev tsim no tsim ib qho chaw tshwj xeeb ntawm daim di ncauj tseem ceeb thiab daim di ncauj thib ob, uas yog ntim nrog cov kua los ntawm kev sib txuas lus, tsim kom muaj qhov tsis txaus ntseeg 'trapped cheeb tsam'. Thaum lub di ncauj tseem ceeb ua hauj lwm, cov kua siab nyob rau hauv 'trapped cheeb tsam' yog siab tshaj lub siab nyob rau hauv lub chav ua hauj lwm chamber, yog li ua tau ib tug txhim khu kev qha sealing xeev.
Raws li kev sim cov ntaub ntawv, qhov xau ntawm Y-zoo li lub nplhaib sealing nrog lub 'raug kaw' tsim nyob rau hauv kev kub siab thiab kev kub ceev ua haujlwm raug txo los ntawm ntau dua 30% piv nrog cov qauv ib txwm muaj.
Kev txhim kho zoo
Ntxiv nrog rau kev txhim kho cov txheej txheem, peb kuj tau txhim kho cov duab ntawm Y-zoo li lub foob. Peb tau tsim lub Y-zoo li lub foob nrog zoo sealing kev ua tau zoo los ntawm kev qhia txog kev siv tshuab computer-aided tsim technology. Lub foob no muaj qhov tsim nyog tshaj qhov seem, uas tuaj yeem hloov kho kom zoo dua rau qhov kev xav tau sealing nyob rau hauv kev ua haujlwm sib txawv.
Hauv kev xyaum, kev txhim kho Y-zoo li lub foob tau zoo heev sealing kev ua tau zoo thiab hnav tsis kam. Raws li cov neeg siv kev tawm tswv yim, nws lub neej kev pabcuam tau nce ntau dua 20% piv nrog cov khoom lag luam ib txwm muaj.
Y-shaped sealing khoom xaiv
Nitrile roj hmab (NBR)
Nitrile roj hmab yog cov khoom siv feem ntau siv rau Y-zoo li cov ntsaws ruaj ruaj. Nws muaj cov roj ua haujlwm zoo, ua kom tsis zoo thiab ua kom sov, thiab tsim nyog rau kev sib khi daim ntaub ntawv nrog kev ua haujlwm kub ntawm -40 degree mus rau +120 degree . Txawm li cas los xij, NBR tsis tshua muaj kev tiv thaiv rau ketone cov kuab tshuaj thiab cov tshuaj oxidizing.
Hauv kev siv tswv yim, peb tau txhim kho cov kuab tshuaj thiab alkali tsis kam ntawm NBR los ntawm kev hloov kho nws. Kev sim cov ntaub ntawv qhia tau hais tias qhov tsis kam ntawm hloov NBR hauv ketone cov kuab tshuaj tau txhim kho ntau dua 50%.
Fluoroelastomer (FKM)
Fluoroelastomer yog cov khoom siv zoo rau Y-zoo li cov ntsaws ruaj ruaj. Nws muaj cov roj ua haujlwm zoo, hnyav ua haujlwm thiab ua haujlwm kub, thiab ua tau zoo nyob rau hauv qhov kub thiab txias thiab chemically corrosive ib puag ncig. Txawm li cas los xij, Viton yog kim.
Txhawm rau txo tus nqi, peb tau tshawb xyuas cov cuab yeej sib xyaw ua ke ntawm Viton nrog lwm cov ntaub ntawv. Los ntawm kev qhia txog qhov tsim nyog ntawm cov fillers thiab additives, peb ua tiav npaj cov fluoroelastomer composite nrog kev ua tau zoo thiab tus nqi qis. Cov ntaub ntawv sim tau pom tias qhov kev ua tau zoo ntawm cov khoom siv sib xyaw yog piv rau cov ntshiab fluoroelastomer, tab sis tus nqi raug txo los ntawm ntau dua 30 feem pua.
