Dab tsi yog qhov kev txiav txim siab txog kev nyab xeeb rau cov phaj cua sov siv hauv Oxygen-Enriched Atmospheres?

Cov pa oxygen ntau ntxiv yog siv rau hauv cov chaw kho mob, kev siv aerospace thiab qee cov txheej txheem tshuaj uas siv cov cua sov. Nyob rau hauv cov xwm txheej zoo li no, feem ntau cov ntaub ntawv muaj kev nyab xeeb tuaj yeem ua rau tawg yooj yim thiab kev ntsuas hluav taws xob zoo li qub yuav tsis txaus. Nws yog ib qho tseem ceeb kom nkag siab txog cov xwm txheej txaus ntshai thiab kev nyab xeeb txhawm rau ua kom muaj kev nyab xeeb ntawm cov phiaj xwm cua sov hauv cov pa oxygen- ua kom muaj cua sov.

Kev phom sij ntawm Oxygen-Ntawm thaj chaw nplua nuj
Yog hais tias ib puag ncig muaj cov pa ntau dua, ces qhov kub thiab txias ntawm cov khoom yog qis dua, thiab lawv hlawv sai dua thiab muaj zog dua. Oxygen enrichment txhim kho tus cwj pwm tua hluav taws thiab txawm tias ib txwm muaj cov khoom siv hluav taws xob zoo li PTFE tuaj yeem ua rau cov nplaim taws kub heev ntawm cov xwm txheej no. Cov ntaub ntawv uas muaj cov thermal conductivity ntau dua yuav ua rau muaj kev phom sij ntawm qhov hluav taws kub hnyav dua vim tias nws tuaj yeem ua rau thaj tsam ntawm - cua sov.

Cov phaj cua sov hauv cov txheej txheem oxygen enriched yuav tsum tau tsim kho kom txo tau cov kev phom sij no los ntawm kev xaiv cov khoom tsim nyog, kev txwv kub thiab kev ruaj ntseg hluav taws xob.

Kev xaiv cov khoom siv rau Oxygen-Ntiaj Teb nplua nuj
Cov khoom siv rau cov cua sov phaj hauv qhov chaw uas muaj cov pa oxygen ntxiv yuav tsum tau kuaj xyuas kom muaj kev sib raug zoo nrog cov pa oxygen siab. Feem ntau, cov hlau yog nyiam tshaj cov polymers vim tias lawv muaj cov ntsiab lus melting ntau dua thiab tsis tshua muaj kev kub hnyiab hauv oxygen - thaj chaw nplua nuj. Cov khoom siv feem ntau yog cov hlau tsis muaj steel, Inconel thiab tooj liab alloys, uas zoo dua tiv taus hluav taws kub thiab tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev pheej hmoo ntawm combustion.

Yog tias tsis yog - nplaum nplaum yuav tsum tau, cov fluoropolymer xaiv yuav tsum tau ua tib zoo xaiv thiab kuaj cov pa oxygen. Feem ntau, cov ntaub ntawv zoo li PTFE raug xaiv, tab sis nws yog ib qho tseem ceeb uas yuav tsum tau ua cov pa oxygen compatibility test (xws li ASTM G63, NASA STD 6001) los xyuas kom meej tias lawv yuav tsis combust nyob rau hauv siab oxygen concentrations. PTFE muaj qhov ntsuas cov pa oxygen siab me ntsis tab sis tseem tuaj yeem ua rau cov pa ntshiab huv hauv qee qhov xwm txheej.

Cov ntsiab lus tseem ceeb ntawm cov khoom siv:
Ignition kuj yog qhov zoo tshaj plaws siv hlau xws li stainless hlau, Inconel thiab tooj liab alloys.

Yog tias cov tshuaj fluoropolymer yuav tsum tsis yog -stick, lawv yuav tsum xeem dhau cov kev ntsuas pa oxygen (xws li ASTM G63, NASA STD 6001).

Kev kuaj cov khoom siv rau ASTM cov qauv yog tsim nyog rau kev siv nyab xeeb hauv cov pa oxygen-enriched ib puag ncig.

Kub txwv thiab txwv kev nyab xeeb
Thaum siv cov cua kub cua sov hauv cov pa oxygen- cov xwm txheej zoo, cov kev txwv kub tsim nyog yuav tsum raug hwm rau kev nyab xeeb. Qhov kub ntawm qhov saum npoo yuav tsum raug tswj kom tsis txhob ncav cuag qhov pib - qhov kub ntawm cov khoom siv. Cov ntsuas kub no ib txwm yuav tsum tau tswj xyuas qis dua qhov kev txwv siv rau cov khoom siv nrog kev nyab xeeb kev nyab xeeb kom tso cai rau kev hloov pauv ib puag ncig, thiab kev hloov pauv hauv cov ntsiab lus oxygen.

Cov ntaub ntawv kuaj thiab pom zoo tsim nyog rau kev siv hauv cov pa oxygen enriched cua yuav tsum tau khaws cia nyob rau hauv qhov kub thiab txias txwv kom txo tau qhov kev pheej hmoo ntawm combustion. Hauv qee qhov xwm txheej, kev tsim cov phiaj xwm cua sov suav nrog kev saib xyuas tas li thiab kev tswj xyuas qhov kub thiab txias kom tsis txhob dhau qhov kev txwv no.

Teeb meem nrog kev tswj qhov kub thiab txias:
Qhov kub ntawm qhov chaw yuav tsum tau khaws cia hauv qab ntawm qhov pib - qhov kub thiab txias ntawm cov khoom.

Kev ntsuas kub yuav tsum suav nrog kev nyab xeeb kev nyab xeeb rau cov pa oxygen concentration variations.

Kev tswj qhov kub thiab txias tuaj yeem siv rau kev saib xyuas tas li.

Kev nyab xeeb hluav taws xob hauv oxygen-enriched atmospheres
Kev ntsuas hluav taws xob kev nyab xeeb yog tsim nyog rau cov phiaj xwm cua sov ua haujlwm hauv cov chaw uas muaj cov pa oxygen. Cov tshuab hluav taws xob tsis raug kaw lossis tsis muaj av muaj feem yuav ua rau hluav taws kub. Cov khoom siv hluav taws xob yuav tsum tau muab tso rau hauv cov ntaub thaiv npog kom tsis txhob nkag ntawm cov pa oxygen. Cov ntaub thaiv npog no yog tsim los tiv thaiv cov pa oxygen mus txog txhua qhov hluav taws xob uas tuaj yeem ua rau lub teeb lossis arc.

Thaum kawg, txhua yam khoom siv hluav taws xob uas ua rau arcing (xws li, cov neeg kho tshuab contactors) yuav tsum tau hloov nrog cov khoom hauv lub xeev relays (SSRs) uas tsis emit sparks thaum ua haujlwm. Grounding yuav tsum tau ua raws li nruj me ntsis kom tsis txhob muaj hluav taws xob ua txhaum cai.

Cov Lus Qhia Tseem Ceeb Txog Kev Nyab Xeeb Hluav Taws Xob:
Cov khoom siv hluav taws xob yuav tsum raug kaw kom tsis txhob nkag ntawm oxygen.

Kev siv cov khoom hauv lub xeev relays (SSRs) es tsis txhob siv cov neeg kho tshuab contactors kom tshem tawm qhov muaj peev xwm ntawm arcing.

Cov kev pheej hmoo suav nrog cov teeb meem hluav taws xob uas tuaj yeem cuam tshuam cov roj, thiab yuav tsum tau txo qis los ntawm kev sib tsoo hauv av.
