Tus qauv tsim thiab kev ua haujlwm ntawm cov foob pob hluav taws xob yog qhov nyuaj heev, muaj ntau yam khoom tseem ceeb. Lawv yog ua los ntawm cov ntsej muag foob, elastomers, cov foob pob hluav taws thib ob, thiab cov khoom siv kho vajtse, txhua tus muaj cov yam ntxwv thiab lub hom phiaj tshwj xeeb.

Cov khoom tseem ceeb ntawm lub tshuab foob pob muaj xws li:

1. Lub ntsej muag tig (Lub nplhaib tseem ceeb):Qhov no yog ib feem ntawm lub foob pob uas tig nrog lub qag. Nws feem ntau muaj lub ntsej muag tawv, tiv taus kev hnav ua los ntawm cov ntaub ntawv xws li carbon, ceramic, lossis tungsten carbide.
2. Lub ntsej muag ruaj khov (Lub rooj zaum lossis lub nplhaib thib ob):Lub ntsej muag uas nyob ruaj khov tseem ruaj khov thiab tsis tig. Feem ntau nws yog ua los ntawm cov khoom siv mos mos uas ua kom tiav lub ntsej muag uas tig, tsim kom muaj qhov sib txuas ntawm lub foob. Cov khoom siv feem ntau suav nrog ceramic, silicon carbide, thiab ntau yam elastomers.
3. Cov Elastomers:Cov khoom siv elastomeric, xws li O-rings thiab gaskets, yog siv los muab qhov kev sib khi yooj ywm thiab ruaj ntseg ntawm lub tsev nyob ruaj khov thiab lub qag tig.
4. Cov Khoom Siv Sealing Thib Ob:Cov no suav nrog cov O-rings thib ob, V-rings, lossis lwm yam khoom sib khi uas pab tiv thaiv cov pa phem sab nraud kom tsis txhob nkag mus rau hauv thaj chaw sib khi.
5. Cov Khoom Hlau:Ntau yam khoom siv hlau, xws li lub plhaub hlau lossis txoj hlua tsav, tuav lub foob sib dhos ua ke thiab khi nws rau ntawm cov khoom siv.

Lub ntsej muag foob tshuab

• Lub ntsej muag foob tig tauLub nplhaib tseem ceeb, lossis lub ntsej muag foob tig, txav mus ua ke nrog lub tshuab tig, feem ntau yog lub qhov. Lub nplhaib no feem ntau yog ua los ntawm cov khoom siv tawv, ruaj khov xws li silicon carbide lossis tungsten carbide. Kev tsim qauv ntawm lub nplhaib tseem ceeb ua kom nws tuaj yeem txhawb nqa lub zog ua haujlwm thiab kev sib txhuam tsim thaum lub sijhawm ua haujlwm ntawm lub tshuab yam tsis muaj kev hloov pauv lossis hnav ntau dhau.

• Lub ntsej muag foob ruaj khovTsis zoo li lub nplhaib tseem ceeb, lub nplhaib sib koom ua ke tseem nyob ruaj khov. Nws yog tsim los ua ib khub sib khi nrog lub nplhaib tseem ceeb. Txawm hais tias nws nyob ruaj khov, nws yog tsim los kom haum rau kev txav mus los ntawm lub nplhaib tseem ceeb thaum tswj hwm lub foob ruaj khov. Lub nplhaib sib koom ua ke feem ntau yog ua los ntawm cov ntaub ntawv xws li carbon, ceramic, lossis silicon carbide.

Elastomers (O-rings los yog bellows)

Cov ntsiab lus no, feem ntau yog O-rings lossis bellows, ua haujlwm los muab qhov elasticity tsim nyog los tswj lub foob ntawm lub tshuab foob sib dhos thiab lub tshuab lub qhov lossis lub tsev. Lawv pab txhawb nqa me ntsis qhov tsis sib xws thiab kev co yam tsis muaj kev cuam tshuam rau lub foob. Kev xaiv cov khoom siv elastomer nyob ntawm ntau yam, suav nrog qhov kub thiab txias, siab, thiab qhov xwm txheej ntawm cov kua dej raug kaw.

Cov Se Thib Ob

Cov foob thib ob yog cov khoom uas muab thaj chaw sib khi zoo li qub hauv lub rooj sib dhos foob. Lawv ua kom lub foob ua haujlwm tau zoo thiab ntseeg tau, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej dynamic.

Kho vajtse

• Cov dej ntwsCov springs muab qhov hnyav tsim nyog rau cov ntsej muag foob, ua kom muaj kev sib cuag tas li ntawm lawv txawm tias nyob rau hauv ntau yam kev ua haujlwm. Qhov kev sib cuag tas li no ua kom muaj kev foob txhim khu kev qha thiab zoo thoob plaws hauv kev ua haujlwm ntawm lub tshuab.

• Cov khoom tuavCov khoom tuav ntau yam khoom ntawm lub foob ua ke. Lawv tswj qhov sib dhos thiab qhov chaw ntawm lub foob kom raug, kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws.

• Cov phaj qogCov phaj gland yog siv los txuas lub foob rau ntawm cov tshuab. Lawv txhawb nqa lub foob sib dhos, ua kom nws ruaj khov rau hauv qhov chaw.

• Teeb tsa cov ntsia hlau: Cov ntsia hlau yog cov khoom me me, siv los khi lub foob sib dhos rau ntawm tus ncej. Lawv ua kom lub foob nyob ruaj khov thaum lub sijhawm ua haujlwm, tiv thaiv kev hloov pauv uas yuav ua rau lub foob tsis ua haujlwm zoo.

Txhua yam khoom ntawm lub foob pob ua lub luag haujlwm tseem ceeb hauv kev kaw cov tshuab ua haujlwm kom zoo. Los ntawm kev nkag siab txog kev ua haujlwm thiab qhov tseem ceeb ntawm cov khoom no, ib tus tuaj yeem nkag siab txog qhov nyuaj thiab qhov tseeb uas xav tau hauv kev tsim thiab tswj cov foob pob ua haujlwm kom zoo.
