Dab tsi yogHNBR RGD O-Ring Rau Vlave
HNBR RGD O-Ring rau Valve yog hais txog lub nplhaib O-ntiv nplhaib uas siv cov khoom siv HNBR thiab muaj cov khoom siv roj los tiv thaiv sai. Nws yog siv los kaw thiab tiv thaiv lub valve kom tiv thaiv kom tsis txhob tawm thiab puas. Nws muab kev ruaj ntseg sealing kev ua tau zoo nyob rau hauv siab siab thiab hnyav ua hauj lwm tej yam kev mob thiab yog haum rau ntau yam kev lag luam daim ntaub ntawv.
RGD yog dab tsi?
Kev tshaj tawm hauv cov ntawv siv roj thiab roj av tuaj yeem ua rau muaj kev kub ntxhov heev thiab tuaj yeem muaj nyob rau hauv cov kua thiab roj theem. Txawm hais tias qhov nruab nrab yog nominally kua yuav muaj cov roj yaj uas tuaj yeem ua rau RGD puas. Cov pa roj no tau nkag mus rau hauv cov elastomer seals dhau sijhawm kom txog thaum cov pa roj hauv lub elastomer nyob rau tib lub siab raws li qhov system. Qee qhov o yuav ua rau qhov nqus no tab sis thaum lub zog siab tseem siab tsis muaj kev puas tsuaj rau elastomer yuav tshwm sim. Yog hais tias lub kaw lus siab tau tso tawm sai sai, piv txwv li vim yog qhov tshwm sim ntawm qhov tshwm sim los yog qhov qhib ntawm lub valve, qhov sib txawv ntawm qhov siab tshwm sim ntawm cov roj ntim hauv lub elastomer foob thiab ib puag ncig ib puag ncig. Cov pa roj hauv lub elastomer yuav nthuav dav uas tuaj yeem ua rau cov khoom ua rau blistering thiab tawg. RGD-induced kev puas tsuaj muaj peev xwm ua rau muaj kev puas tsuaj tsis zoo.
Lus Cim: RGD kev puas tsuaj yog qhov tshwm sim ntawm lub cev thiab tsis yog vim muaj tshuaj lom neeg. Txawm li cas los xij, qee cov pa roj xws li H2S, kuj tseem yuav tshuaj tua cov elastomers, thiab yuav tsum tau txiav txim siab cais thiab ntxiv rau qhov muaj peev xwm rau RGD kev puas tsuaj.
HNBR RGD O-Ring
RGD stands rau "Resistance to Rapid Gas Decompression", uas txhais tau hais tias tsis kam mus rau cov roj decompression sai. Lub O-ring foob no tshwj xeeb tsim thiab ua tiav los tiv thaiv kev puas tsuaj los ntawm kev puas tsuaj sai uas tshwm sim hauv qhov chaw muaj roj siab. Cov yam ntxwv no ua rau nws siv dav hauv cov roj cua siab thiab cov kav dej.
Linde Polymer HNBR RGD O-ring yog NORSOK M-710-cov ntaub ntawv pov thawj uas muaj cov tshuaj lom neeg zoo tshaj plaws thiab kev ua haujlwm kub kub, ua ke nrog tshwj xeeb tsis kam rau cov pa roj sai sai decompression (RGD). Ua tau raws li qhov yuav tsum tau muaj ntawm cov modulus siab thiab hardness, thiab nrog rau nws cov tshuaj zoo heev, thermal, thiab RGD tsis kam, yog qhov kev xaiv zoo tshaj plaws rau sealing daim ntaub ntawv nyob rau hauv lub harshest ib puag ncig.
Thaum feem ntau cov elastomers muab txoj hauv kev rau cov kab nrib pleb thiab cov hlwv thaum absorbed gases nyob rau hauv lub elastomer seals quab yuam lawv txoj kev tawm hauv qab decompression, Linde Polymer HNBR RGD O-ring tseem ua rau kev cia siab vim nws superior RGD cov khoom thiab dav chemical compatibility.
muaj nuj nqi
- Kev ua haujlwm ntawm HNBR RGD O-Ring Rau Vlave yog muab kev sib khi thiab cov dej pov thawj. Tshwj xeeb, lawv ua lub luag haujlwm tseem ceeb hauv qab no ntawm qhov txuas ntawm lub valve:
- Sealing kev ua tau zoo: HNBR O-ring tuaj yeem sau qhov sib txawv ntawm qhov sib txuas kom tsim tau lub foob zoo thiab tiv thaiv cov kua los yog roj. Qhov no yog qhov tseem ceeb rau kev ua haujlwm ntawm lub valve, tshwj xeeb tshaj yog nyob rau hauv high-pressure los yog high-temperature tej yam kev mob, uas yuav tsum tau txhim khu kev qha sealing kev ua tau zoo.
- Kev tswj cov kua dej: O-rings tuaj yeem siv los tswj cov dej ntws, xws li hauv cov tshuab hydraulic. Lawv tuaj yeem tiv thaiv kom tsis txhob muaj cov roj hydraulic thaum ua kom lub cev ua haujlwm zoo.
- Qhov kub thiab txias ib puag ncig: HNBR RGD O-Ring Rau Vlave feem ntau muaj qhov kub thiab txias tsis kam, thiab tuaj yeem ua haujlwm ruaj khov hauv qhov kub thiab txias.
- Corrosion tsis kam: Qhov O-ring no feem ntau muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv thaiv kev yaig ntawm ntau yam tshuaj, yog li txuas nws lub neej kev pab cuam.
- Kev tiv thaiv rau compression deformation: HNBR cov khoom muaj siab elasticity thiab tsis kam rau compression deformation. Thaum lub valve raug kaw, O-ring tuaj yeem tiv taus lub siab thiab tswj nws cov qauv qub, kom ntseeg tau tias kev sib khi ua haujlwm tsis raug puas tsuaj.
