Rocket Roj Radve Ntsaws Ruaj Ruaj

Hauv kev lag luam Aerospace, kev ua haujlwm sib khi ntawm cov roj foobET cov roj hluav taws xob yog txhais tau hais tias muaj kev nyab xeeb thiab lub hom phiaj ua tiav. Raws li cov tseem ceeb tivthaiv nyob rau hauv high-siab, hnyav heev, cov ntsaws ruaj ruaj yuav tsum muaj cov yam ntxwv ntawm kev ua haujlwm heev, xoom so kom huv, thiab lub neej ntev. Kab lus no yuav tob tob txog cov txheej txheem kev xaiv, thiab cov ntawv thov kev lag luam ntawm cov foob pob hluav taws xob thiab muab cov kev daws teeb meem rau ntiaj teb rau cov neeg siv khoom.

Rocket roj valve ntsaws ruaj ruaj yog qhov xav tau rau lawv qhov kev ua tau zoo

Qhov kawg kub siab ntev

Rocket roj (piv txwv kua pa oxygen, kua hydrogen) yog cov ntsuas kub, thaum lub caij kub ntawm qhov kub siab tshaj 3000 degree. Cov ntaub ntawv sealing yuav tsum yog tus qauv zoo nkauj thiab nruj hauv thaj tsam ntawm {2}} degree rau} degree kom tsis txhob emgrithlement lossis thermal decomposition.

Tshuaj lom neeg kuj thiab tsawg permeability

Roj media (piv txwv li nitrous tetroreshide, hydrazine) yog cov xeb zoo, thiab cov ntsaws ruaj ruaj yuav tsum tau tawm mus o, oxidation thiab molecular nkag. Fluorooelastomers (FKM) thiab fluorosilicone Rubbers (FVMQ) yog cov ntaub ntawv ntawm kev xaiv vim lawv cov qauv molecular ruaj khov.

Kev siv hluav taws xob siab dynamic kev cia siab

Lub valve tuaj yeem tiv thaiv qhov kev cuam tshuam siab ntawm ntau dua 50mpa thaum qhib thiab kaw, thiab yuav tsum muaj lub zog siab thiab tawm tsam kev tawm tsam muaj peev xwm. Kev siv ntau-txheej sib xyaw ua ke tsim qauv lossis hauv kev sib xyaw nrog polytetrosraethoroethylene (PTFE) tuaj yeem txhim kho kev ua tau siab.

Cov Khoom Sib Tw Technology hauv Aerospace-Cov Khoom Saws Ntaus Cim

Fluoroelastomer (FKM)

Kub Ntau Yam: {{-20 degree rau +300 degree

Cov yam ntxwv: tiv taus cov roj av, muaj zog acids, ozone, zoo tshaj plaws hluav taws xob tsis kam, haum rau sealing cav lub tshuab dej thiab roj kab 69.

Cov ntaub ntawv: Lub cim tshiab ntawm hluav taws xob tswj kev nyab xeeb li qub ntawm Zhonge Fluorastomer tso tawm kom ua tiav tswj cov foob pob hluav taws xob hauv lub nkoj siab.

Cov roj fluorosilicone roj hmab (fvmq)

Kub Ntau Yam: {{-50 degree rau +200 degree

Cov yam ntxwv: sib txuas cov tshuaj lom neeg tiv thaiv fluoroelastomer nrog cov roj hmab qis ntawm silicone roj hmab thiab siv nyob rau hauv cov xwm txheej cryogenic seatural 48 ntawm cov roj puv li qub.

Polytetrafluoroethylene (PTFE) Composites

Kub Ntau Yam: {{-200 degree rau +260 degree

Cov yam ntxwv: Kev ua rau nws tus kheej lubricating, tsawg coefficient ntawm kev sib txhuam, haum rau dynamic sealing ntawm cov khoom ceev. Cov tshuab ua haujlwm muaj zog yog txhim kho los ntawm filling nrog carbon fiber lossis iav fiber ntau.

Qhov Zoo ntawm Customized Sealing cov kev daws teeb meem

Peb muab cov kev txhawb nqa tag nrho lub neej, npog kev xaiv, cov khoom siv, kev xeem thiab ntawv pov thawj, thiab cov huab hwm coj tsim khoom:

Kho kom haum rau cov neeg ua haujlwm

Tailor-ua foob hla kev sib sau ua ke thiab hardness (ntug dej hiav txwv {2}}) nyob ntawm seb hom kua (kua / npauj npaim (Npauj npaim, pob).

Kev nrawm nrawm sim

Simulate 20 xyoo ntawm cia lub neej los ntawm thermal-oxygen laus, thiab lwm yam kev kuaj mob kom ntseeg tau tias kev ua tau zoo tom qab kev cia siab.

Nruj ua kom zoo

Hauv kab nrog Cnas cov qauv ntawv pov thawj, kev siv cov cuab yeej ntsuas ntsuas, thiab lwm cov khoom siv kom ua tiav qhov tseeb thiab xoom kom pom tseeb.

Kev Lag Luam Kev Lag Luam thiab Cov Neeg Siv Khoom Dab Neeg
