Tic ki pii ma ki lwongo ni liquid hydrogen (LH2).
I kare ni, pii ma ki lwongo ni liquid hydrogen ki tiyo kwede ki temo tic kwede i kare ma pat pat. I lok kom yamo, ki romo tic kwede ma calo moo me cwalo roket ki bene twero kelo yamo ma lyet i yamo ma mol ki yamo. Ki kony pa "cayan madit," pii ma ki lwongo ni liquid hydrogen odoko gin ma pire tek i jami ma tiyo matek, jami ma weko teko me mac doko tek, ki jami ma ki lwongo ni nuclear fusion devices. Kit ma miti pa dano pi dongo lobo ma rii pi kare malac tye ka mede kwede, pii ma ki lwongo ni liquid hydrogen dong ki tiyo kwede calo moo ki motoka ki yeya mapol i mwaka manok ma okato ni. I kit me tic ma malo ni, gin ma pire tek pa valve nen atir atir. Tic maber ki gen pa valve obedo bute ma pire tek me kelo pii ma ki lwongo ni liquid hydrogen (yubu, tero, gwoko ki poko). Tic ma mako pii ma ki lwongo ni liquid hydrogen tek. Ki mwaka 30 me ngec ma mako tic ki jami ma tiyo maber ma romo -272°C, Velan obedo ka nywako i yub mapol pi kare malac, ki nen maber ni en oloyo peko me tic ki pii ma ki lwongo ni liquid hydrogen ki teko ne.
Peko ma tye i kare me yubu
Peko, lyeto ki dwong pa hydrogen weng obedo jami ma pire tek ma ki temo i yub me valve. Me weko tic pa valve bedo maber, kit ma ki yubu kwede ki yero jami ma ki tiyo kwede tye gin ma pire tek. Valve ma ki tiyo kwede i tic ki hydrogen ma pii pii nongo peko mukene, medo ki adwogi marac ma hydrogen kelo i kom jami ma ki yubu ki cuma. I rwom me lyeto ma piny tutwal, jami ma ki tiyo kwede i valve omyera pe ocung matek i kom lweny pa hydrogen molecules (jami mogo ma twero balo ne pud kitye ka nyamo ne i rwom ma malo), ento omyera bene obed ka tic maber pi kare malac i kare me kwo gi. Malube ki rwom me dongo pa jami ma ki tiyo kwede i kare ni, dano ma gi tiimo tic ni gitye ki ngec manok i kom tic ki jami ma pe ki yubu ki cuma i tic ki hydrogen. Ka itye ka yero gin ma ki tiyo kwede me umu, omyera i nen gin ni. Gengo maber bene obedo gin ma pire tek ma nyutu kit ma ki yubu kwede jami. Tye apoka poka me lyeto ma romo 300°C i kin hydrogen ma tye ki pii ki lyeto ma tye i ot (lyeto me ot), ma kelo rwom me lyeto ma pat pat. Gin acel acel ma tye i valve ni obi kato ki i rwom ma pat pat me dongo ki dwoko piny. Apokapoka eni twero kelo pii ma twero kelo peko i kom jami ma pire tek ma ki umu kwede. Kit ma ki umu kwede valve stem ni bene tye gin ma ki keto iye yub ni. Lok me aa ki i ngiico me doko lyeto kelo lyeto. Kabedo ma lyet i kom gin ma ki lwongo ni bonnet cavity twero doko ngiico, ma twero balo tic pa stem sealing ki balo tic pa valve. Medo ikom meno, rwom me lyeto ma piny tutwal ma tye -253°C nyutu ni diro me gengo lyeto maber loyo mite me neno ni valve ni twero gwoko hydrogen ma tye i rwom me lyeto man kun dwoko piny rweny ma bino pi lyeto. Ka lyeto tye ma ki keto i pii ma ki lwongo ni liquid hydrogen, en obi doko yamo ki obi mol. Pi en keken, oxygen ma ki lwongo ni oxygen condensation time i kare ma gin ma ki lwongo ni insulation ni otur iye. Ka oxygen orwatte ki hydrogen onyo jami mukene ma lyel, peko me mac mede. Pi meno, ka kiporo ki peko me mac ma valve twero wok ki iye, valve omyera ki yub ki jami ma gengo mac, kacel ki jami ma gengo mac, jami ma ki tiyo kwede ki waya, weng ki twero ma ki moko. Man miyo ni valve ni tiyo maber ka mac ocako lyel. Medo rwom me teko bene obedo gin ma twero kelo peko ma twero weko valve pe tiyo. Ka pii ma ki lwongo ni liquid hydrogen ni ki mako i kin dul kom ma ki lwongo ni valve ki lyeto ki pii ma ki lwongo ni liquid hydrogen evaporation time i kare acel, obi kelo medo rwom me teko. Ka tye apoka poka madit i rwom me teko, cavitation (cavitation)/noise time. Jami eni twero kelo agiki me kwo pa valve ni oyotoyot, ki bene kelo rweny madwong pi peko ma tye i yub ne. Labongo paro kit ma tic tye kwede, ka jami ma ki waco malo ni ki twero keto i tic ki jami ma rwate ki tic ma ki twero timo i yub me yubu, man twero neno ni tic pa valve ni tye maber ki ma genne. Medo ikom meno, tye peko me yubu jami ma mako lok ma mako kwo pa dano, ma calo pii ma mol ki i ngom. Hydrogen tye ma pat: jami ma tiino, pe ki kala, pe ki ngwec, ki twero wango. Kit magi nyutu gin ma mite pi zero leakage.
