Koj tuaj yeem tuaj hla ntau cov o-rings hauv koj lub neej, txawm koj paub nws los tsis paub. Los ntawm cov tsheb mus rau cov koob yees duab, cov me ntsis donut puab cov khoom yog qhov hnov qab tam sim ntawd tab sis qhov kawg pab tau. Lawv yog tej zaum ib qho kev hloov kho loj tshaj plaws hauv kev tsim kho tshuab kom txog rau hnub, cia peb txhim kho cov tshuab tshiab, cov khoom lag luam zoo dua thiab cov chaw ua haujlwm ruaj khov dua. Yog li, o cov nplhaib siv rau dab tsi, thiab vim li cas lawv thiaj li nrov? Cia peb kawm saib.
Vim li cas o cov nplhaib siv?
O cov nplhaib muaj qee cov yam ntxwv zoo heev uas ua rau lawv muaj qhov tshwj xeeb tseem ceeb ntawm ntau qhov ua kom raug cav tsim. Lawv qhov sib thooj tshwj xeeb kom rov qab mus rau lawv qhov qub thaum lub sijhawm sib tshooj muaj qhov kev nyuaj siab rau nws txhais tau tias lawv yog ib qho ntawm cov kev lag luam thiab txhim khu kev qha ntawm kev ua rau lub zog ruaj khov.
Lwm qhov laj thawj o cov nplhaib sib txuas yog siv ntau yog nqes rau ntau cov ntaub ntawv uas lawv tuaj yeem tsim los ntawm. Feem ntau ntawm o cov nplhaib yog tsim los ntawm elastomers, uas yog ib hom ntawm cov nplaim polymer, tab sis muaj ntau yam loj ntawm cov elastomers muaj, txhua tus muaj lub zog sib txawv, tsis muaj zog thiab pom zoo. Daim ntawv thov uas lub nplhaib o yog lub hom phiaj rau yuav txiav txim siab seb hom khoom twg haum tshaj, piv txwv li:
Siab thiab qis kub : Silicone thiab fluorosilicone tuaj yeem tiv taus kub li tsawg li -100 ° C. Cov haujlwm hauv Cryogenic yuav xav kom muaj lub foob uas tuaj yeem tiv thaiv nrog qhov kub thiab txias xws li NES Astra Seal®. Rau qhov kub thiab txias heev, FFKM ua haujlwm nce txog 316 ° C
Kev ua kom muaj tshuaj lom neeg : Viton ™, tseem hu ua FKM / FPM, o cov nplhaib tiv taus ntau yam tshuaj lom neeg thiab ua haujlwm ntawm qhov kub thiab txias heev
Cov dej kub thiab pa taws : Ethylene propylene o rings (EPDM) muaj kev tiv thaiv zoo rau cov dej khov thiab dej kub, ntxiv rau cawv, dej cawv muaj zog alkalis thiab kua dej hauv cov ntawv thov tsheb.
Cov roj thiab cov kua roj hydraulic : Buna-N o rings, tseem hu ua nitrile o rings, yog qhov zoo tshaj plaws rau siv rau qhov chaw uas muaj cov roj lossis cov kua hydraulic nyob ib puag ncig.
Raws li koj tuaj yeem pom, rau ntau zoo nkauj txhua daim ntawv thov uas koj tuaj yeem xav txog, yuav muaj lub nplhaib o uas tuaj yeem kho qhov ib puag ncig ntawd. Qhov no txhais tau tias lawv muaj txiaj ntsig hauv kev siv ntau yam, los ntawm cov cuab yeej siv tau pom nyob ib puag ncig tsev mus rau lub tshuab loj gigantic siv hauv kev tsim khoom thiab txawm tias nyob hauv qhov chaw shuttle!
