Semiconductor nqus tsev yog ib qho ntawm cov khoom siv tseem ceeb siv los tsim cov khoom siv semiconductor. Nws yog lub kaw lus kaw nyob rau hauv ib qho chaw huv si, tsis tshua muaj siab rau kev tuav thiab ua cov khoom siv semiconductor thiab cov khoom siv.
Hauv cov tshuab nqus tsev semiconductor, cov khoom siv roj hmab ua haujlwm siab feem ntau yog siv vim qhov yuav tsum tau ua kom huv huv thiab tsis tshua muaj paug. Nov yog qee yam hom roj hmab foob:
Viton (FPM) Seals: Viton yog tshuaj thiab kub resistant fluoroelastomer dav siv hauv lub tshuab nqus tsev. Nws muaj qhov kub thiab txias ua haujlwm zoo, tiv thaiv corrosion thiab tsis tshua muaj roj permeability, ua rau nws tsim nyog rau sealing yuav tsum tau tiv taus lub tshuab nqus tsev siab thiab kub ib puag ncig.
Nitrile (NBR) Seals: Nitrile yog cov roj hmab hluavtaws dav dav nrog cov roj zoo thiab ua kom puas. Hauv cov tshuab nqus tsev semiconductor, Nitrile seals feem ntau yog siv rau qee qhov tsis muaj qhov kub thiab txias, kev siv tsis muaj corrosive, xws li cov tshuab nqus tsev qis thiab cov kav dej sib txuas.
Silicone (VMQ) foob: Silicone yog qhov kub-resistant silicone roj hmab nrog zoo elasticity thiab kub tsis kam. Nws feem ntau yog siv hauv cov tshuab nqus tsev semiconductor los tiv thaiv cov kev xav tau ntawm kev sib khi hauv qhov chaw kub kub, xws li kev kho cua sov, kev sib tsoo, thiab kev ua kom kub kub.
EPDM foob: EPDM yog ethylene propylene roj hmab nrog oxidation zoo, acid thiab alkali tsis kam. Hauv cov tshuab nqus tsev semiconductor, EPDM cov ntsaws ruaj ruaj feem ntau yog siv rau hauv qhov tsis muaj qhov kub thiab txias, tsis muaj corrosive daim ntawv thov xws li lub tshuab nqus tsev qis thiab cov kav xa hluav taws xob.
Cov roj hmab foob no muaj cov yam ntxwv sib txawv thiab kev siv ntau yam. Thaum xaiv lub foob tsim nyog, yam xws li cov txheej txheem kev ua haujlwm, qhov kub thiab txias, cov khoom nruab nrab, thiab cov kev xav tau siab yuav tsum raug txiav txim siab. Tsis tas li ntawd, txhawm rau xyuas kom meej sealing kev ua tau zoo, kev tsim khoom thiab kev teeb tsa ntawm cov ntsaws ruaj ruaj kuj yuav tsum ua raws li cov txheej txheem nruj.
Hauv cov tshuab nqus tsev semiconductor, ntxiv rau cov roj hmab foob, cov roj hmab gasket feem ntau yog siv los ua kom muaj kev sib khi zoo. Nov yog qee yam hom roj hmab foob:
O-ring gasket: O-ring yog roj hmab gasket nrog lub voj voog hla ntu thiab siv dav hauv cov tshuab nqus tsev semiconductor. Nws muaj qhov zoo sealing kev ua tau zoo thiab compression deformation muaj peev xwm, thiab tuaj yeem hloov mus rau qhov sib txawv sealing, xws li cov yeeb nkab txuas, li qub, pob qij txha, thiab lwm yam.
Flat seal: Lub foob tiaj tiaj yog cov roj hmab tiaj tiaj uas feem ntau siv rau kev sib txuas flange hauv cov tshuab nqus tsev semiconductor. Nws ua tiav kev sib khi los ntawm kev sib cuag nrog lub flange nto thiab feem ntau yog ua los ntawm cov khoom siv roj hmab kub-resistant xws li Viton lossis Silicone.
U-shaped gasket: U-shaped gasket yog U-shaped cross-section roj hmab gasket haum rau cov kev xav tau tshwj xeeb hauv cov tshuab nqus tsev semiconductor. Nws feem ntau yog siv los kaw cov plungers, piston pas nrig, lub tog raj kheej thiab lwm yam khoom, thiab muaj kev sib khi zoo thiab ua haujlwm rau compression deformation.
V-shaped gasket: V-shaped gasket yog V-shaped cross-section roj hmab gasket feem ntau siv rau li qub thiab rotating ncej ntsaws ruaj ruaj hauv semiconductor nqus tshuab. Nws ua tiav zoo sealing los ntawm kev sib cuag nrog lub sealing nto, thiab muaj zoo sealing thiab hnav tsis kam.
Kev xaiv ntawm cov roj hmab ntsaws ruaj ruaj yog txiav txim siab raws li cov kev cai tshwj xeeb, kev ua haujlwm thiab cov khoom siv xov xwm. Nyob rau tib lub sijhawm, kev xaiv cov khoom siv ntawm lub gasket kuj tseem ceeb heev. Cov khoom siv feem ntau suav nrog Viton, Nitrile, Silicone, thiab lwm yam. Cov kev xaiv tshwj xeeb yuav tsum xav txog yam xws li qhov kub thiab txias, tshuaj tiv thaiv corrosion, thiab roj to. Thaum txhim kho lub gasket, yuav tsum tau them nyiaj mloog mus ua kom lub sealing nto huv si thiab xyuas kom meej tias lub gasket yog ntsia thiab nias kom raug kom tau ib tug zoo sealing nyhuv.
