Ib co dab tsi tseem ceeb los txiav txim siab thaum xaiv cov khoom siv kom raug rau daim ntawv thov?
Tus nqi zoo thiab cov xim tsim nyog
Muaj Qhov Muag
Txhua yam cuam tshuam rau hauv cov system sealing: piv txwv li kub ntau, kua dej thiab siab
Cov no yog txhua yam tseem ceeb los txiav txim siab hauv koj qhov system sealing. Yog tias txhua yam paub paub, nws yuav yooj yim xaiv cov khoom raug.
Tab sis yuav tsum tau ua ntej yog tias cov khoom yuav tsum muaj ruaj khov. Yog li thawj qhov uas yuav tsum xav txog yog kev ua haujlwm ua haujlwm. Cia peb pib nrog qhov ua tau zoo.
System lub neej thiab tus nqi yog qhov tseem ceeb (Tianjin Tanggu Dej-Real Valve Co., Ltd) Los xav txog. Txhua yam yuav cuam tshuam koj daim ntawv thov kev ua tau zoo. Nws yog ib qho tseem ceeb kom txiav txim siab tsim tsim cov qauv tsim qauv raws li daim ntawv thov. Qhov no suav nrog cov ntaub ntawv siv, cov duab kho vajtse thiab cov txheej txheem ntau lawm. Kuj tseem muaj cov teeb meem ib puag ncig los txiav txim siab nrog rau suav nrog: nias, ntsuas kub, sijhawm, sib dhos thiab xov xwm.
elastomer
Elastomers tau nrov rau lawv cov elasticity zoo. Tsis muaj lwm yam khoom siv muaj tib theem ntawm elasticity.
Lwm cov ntaub ntawv xws li polyurethanes thiab thermopastics yog ntau tiv taus kev nyuaj siab dua elastomers.
Cov khoom siv roj hmab tuaj yeem siv tau rau ntau qhov sib txawv.
Cov Khoom Tseem Ceeb Cov Khoom Siv

kev nyuaj
Lub zog tensile
Lwm cov yam tseem ceeb muaj
•Teeb tsa compression compression compression
•Thaum Tshav Kub Kub Ua
•Tsawg qhov cua sov yooj yim
•Tshuaj Muaj Tshuaj Ntau
•Kev Tawm Tsam Laus
•puas ua
Qhov tseem ceeb tshaj plaws yog qhov elasticity ntawm cov khoom siv roj hmab. Cia peb kawm paub ntxiv txog qhov no.
Elasticity yog qhov tshwm sim ntawm vulcanization. Elastomeric cov ntaub ntawv, xws li vulcanized roj hmab, yuav rov qab mus rau lawv cov qauv qub yog tias deformed.
Cov ntaub ntawv tsis sib xws, xws li cov roj hmab tsis yooj yim, yuav tsis rov qab mus rau lawv lub xeev tseem yog deformed. Vulcanization (xws liNpauj npaim ob chav Flange) yog cov txheej txheem ntawm kev hloov roj hmab rau hauv cov khoom siv elastomeric.
Kev xaiv ntawm elastomers yog tsuas yog raws li:
•Ntau yam kev ua haujlwm kub
•Kuj rau cov dej thiab roj av
•Kuj nrog Weathering, Ozone thiab UV Rays
Kev xaiv ntawm elastomers yog tsuas yog raws li:

Rau cov ntsiab lus uas yuav tsum tau txiav txim siab thaum xaiv cov khoom lag luam nto nkoj nto
Cov saum npoo ntim yog qhov tseem ceeb tshaj plaws ua haujlwm ntawm lubib lub dab tsi uas qhib thiab kaw, qhov zoo tshaj plaws ntawm kev sib khi ncaj qha cuam tshuam rau lub neej pabcuam ntawm lubib lub dab tsi uas qhib thiab kaw, thiab cov khoom siv ntawm cov chaw sib khi yog qhov tseem ceeb ua kom ntseeg tau tias qhov zoo ntawm kev sib khi saum npoo. Yog li ntawd, cov hauv qab no yuav tsum tau txiav txim siab thaum xaiv cov pob zeb sealing nto:
①Corrosion tsis kam. "Corrosion" yog cov txheej txheem nyob rau hauv uas ntawm kev sib khi saum npoo yog puas nyob rau hauv kev txiav txim ntawm qhov nruab nrab. Yog tias cov nplaim kev sib khi yog corroded, kev sib khi ua tau zoo tsis tuaj yeem lav, yog li cov khoom siv ntawm cov khoom sib khi yuav tsum yog corrosion-resistant. Kev tiv thaiv corrosion tsis kam ntawm cov ntaub ntawv tsuas yog nyob ntawm cov ntawv ntawm cov khoom siv thiab nws cov tshuaj ruaj khov.
②Anti--abruction. "Kos" yog hais txog kev puas tsuaj los ntawm kev sib txhuam ntawm cov khoom thaum lub sijhawm txheeb ze txav ntawm cov chaw sib khi. Qhov no zoo ntawm kev puas tsuaj no yuav tsis muaj kev puas tsuaj rau kev sib tsoo saum npoo. Yog li no, cov khoom sib khi saum npoo yuav tsum muaj cov tshuaj tiv thaiv zoo, tshwj xeeb tshaj yog rau cov rooj vag. Cov khawb paus tiv thaiv cov khoom siv yog feem ntau txiav txim los ntawm cov khoom sab hauv ntawm cov khoom.
③Yaig Kuj. "Yaig" yog cov txheej txheem ntawm kev rhuav tshem cov nplaim ntim khoom thaum lub nruab nrab ntws los ntawm kev sib khi saum npoo ntawm kev nrawm. Qhov kev puas tsuaj no yog qhov pom tseeb ntau dua ntawm cov roj teeb thiab muaj kev nyab xeeb siv nyob rau hauv cov hluav taws xob kub thiab muaj kev cuam tshuam siab rau kev puas tsuaj ntawm kev sib khi ua tau zoo. Yog li ntawd, yaig kuj tseem yog ib qho ntawm cov cai tseem ceeb rau cov khoom sib khi.
④Nws yuav tsum muaj qee yam nyuaj, thiab lub hardness yuav poob qis hauv kev ua haujlwm kub.
⑤Txoj kab nthuav dav ntawm cov khoom sib khi thiab cov khoom siv cev yuav tsum zoo sib xws, uas yog qhov kom tsis txhob muaj kev ntxhov siab ntxiv thiab txo qis ntawm qhov kub.
⑥Siv nyob rau hauv cov kev mob siab, yuav tsum muaj txaus tiv thaiv oxidation, thermal rog tsis kam thiab thermal lub voj voog cov teeb meem.
Nyob rau hauv cov xwm txheej tam sim no, nws yog qhov nyuaj kom nrhiav tau cov khoom sib khi ua cov khoom siv ua kom tiav cov cai saum toj no. Peb tsuas yog tsom rau kev ua raws li cov kev xav tau ntawm qee yam raws li kev sib txawv hom valve thiab siv. Piv txwv li, cov li qub siv hauv kev ceev tshaj plaws yuav tsum tau them nyiaj tshwj xeeb rau cov yaig Kuj yuav tsum tau ntawm cov chaw sib foob; Thiab thaum nruab nrab muaj cov khoom siv impurities, cov khoom sib khi saum cov khoom siv sib luag nrog kev tawv ntau dua.
