Ka nānā ʻana i nā pilikia i loko o nā pahu mālama cryogenic

ʻO kanā mea hana pahu pahu mālama cryogenice hōʻuluʻulu i kēia mau manaʻo a e kālailai i nā pilikia maʻamau onā ipu cryogenici ka nana manawa:

1. Nalowale o ka momi.
Hoʻokaʻawale ʻia nā pahu mālama pahu Cryogenic i loko o ke ʻano o ka pauka a me ke ʻano insulation multi-layer kiʻekiʻe e like me ke ʻano o ka vacuum. Nui nā kumu e hiki ai ke hoʻopili i ka nalowale o ka vacuum, e like me:

ʻO ka mea mua, ʻo ia ka mana o nā mea insulation thermal (powder pearl sand, thermal insulation aluminum foil, adsorption materials, etc.) i ka interlayer. Ma muli o nā waiwai kino like ʻole a me nā ʻano kino o nā mea insulation thermal, ʻokoʻa hoʻi kā lākou conductivity thermal. Eia kekahi, ʻokoʻa ka conductivity thermal o nā mea insulation thermal like ʻole i nā degere like ʻole o ka vacuum. ʻO ke kānāwai maʻamau, ʻo ia ka emi ʻana o ka vacuum, piʻi ka thermal conductivity.

ʻO ka lua, ʻo ia ka hopena o ke kinoea sandwich vacuum. E like me ka degere o ka momi, ke kinoea maʻiʻo i loko o ka vacuum interlayer mahuahua, a me ka thermal conductivity mahuahua.

ʻO ke kolu ka hopena o ka hanana outgassing o nā mea like ʻole i loko o ka interlayer, ʻo ia ka mea a mākou e kapa ai i ka nui o ka outgassing rate o ka interlayer vacuum. I ka wā lōʻihi, ʻaʻole hiki ke hoʻokuʻu ʻia ka mea i waho, kahi e alakaʻi ai i ka hoʻemi ʻana i ka vacuum.ʻO ka hā o ka hopena o ka mahana. I ka hihia o ka hoʻoili wela paʻa, e emi ana ka hoʻoili wela o nā mea hoʻokalakupua wela e like me ke one pearlescent interlayer me ka emi ʻana o ka mahana.

2. ʻO ka hemahema o nā mea palekana.
ʻO nā kumu o ka hāʻule ʻole o nā mea palekana o ka pahu mālama cryogenic: ua ʻoi aku ka manawa o ka calibration valve palekana, ʻoi aku ka kiʻekiʻe o ke kaomi kūloko o ka pahu, a ʻoi aku ka nui o ka vacuum degere ma mua o ka pae palekana. Aia kahi leak ma ka ʻāpana pili o ka mea palekana, a me kekahi mau pilikia maikaʻi o ka mea palekana, no ka laʻana, ua ʻike ʻia ʻaʻole hiki ke ana ʻia ke ana o ka pahu i ka wā o ka nānā ʻana ma muli o nā pilikia maikaʻi, a ʻaʻole hiki ke ana ʻia ka ʻōpala.

3. Leakage a me ka hau o nā paipu waho a me nā kiwi.
Ke hoʻoholo nei mai ka nānā mau ʻana i nā pahu cryogenic i nā makahiki i hala iho nei, nui nā pilikia me nā paipu pili waho. ʻO nā pilikia nui ka leakage o nā welds i nā paipu waho a me ke ʻano o ka haki ʻana o ka hau o nā paipu. ʻO ke kumu o ka leakage, mai kahi o ka hoʻonohonoho ʻana, ua hoʻokomo ʻia ka pipeline o waho o ka moku kaomi cryogenic ma ka pūnaewele, inā paha e hoʻokō nā kūlana kuʻi ma ka pūnaewele i nā koi kuʻi, a ʻaʻole kūlike ka pae maikaʻi o ka ʻāpana hoʻonohonoho a me ka mea hana. Sex, aia kekahi mau pilikia palekana. Mai ka hiʻohiʻona o ke kaʻina hana, ʻo ke kumu nui ʻaʻole maikaʻi ka hana hoʻopaʻa ʻana o ka pilina, a i ʻole ma muli o ka hoʻopiha pinepine ʻana, aia kahi hoʻololi i ka ʻokoʻa wela ma waena o ka pilina o ka nozzle a me ka casing, kahi e hoʻololi ai i ke koʻikoʻi ma waena o ka ʻāpana pili o ka nozzle a me ka casing a me ka ʻili o ka valve. A hana i ka leak.
