I te whanaketanga o te kaha kawe o te rōkete cryogenic, kei te piki haere hoki te hiahia mō te tere rere whakakī pūwero. He taputapu nui te paipa kawe wai cryogenic i roto i te ao rererangi, e whakamahia ana i roto i te pūnaha whakakī pūwero cryogenic. I roto i te paipa kawe wai pāmahana-iti, nā te pai o te hiri, te ātete ki te pēhanga me te mahi piko o te ngongo korehau pāmahana-iti, ka taea e ia te whakaea me te mimiti i te huringa nekehanga i puta mai i te whakawhānui wera, te whakaheke makariri rānei i puta mai i te huringa pāmahana, te whakaea i te rerekētanga tāutanga o te paipa me te whakaiti i te wiri me te haruru, ā, ka noho hei wāhanga kawe wai nui i roto i te pūnaha whakakī pāmahana-iti. Hei urutau ki ngā huringa tūranga i puta mai i te nekehanga tauranga me te whakahekenga o te hononga whakakī pūwero i roto i te wāhi iti o te pourewa tiaki, me whai ngāwari te paipa kua hangaia ki ngā ahunga whakawhiti me te roa.

Ka whakanuia e te ngongo korehau waikura hou te diameter o te hoahoa, ka whakapai ake i te kaha whakawhiti waikura waikura, ā, he ngāwari te urutau ki ngā taha me ngā taha whakaroa.

Te hoahoa hanganga whānui o te ngongo korehau cryogenic

E ai ki ngā whakaritenga whakamahinga me te taiao rehu tote, ko te rauemi whakarewa 06Cr19Ni10 te mea i whiriwhiria hei rauemi matua mō te paipa. E rua ngā paparanga o ngā tinana paipa o te huihuinga paipa, te tinana o roto me te tinana whatunga o waho, e honoa ana e te tuke 90° i waenganui. Ka takaihia te pepa konumohe me te kakahu kore-kawa ki te mata o waho o te tinana o roto hei hanga i te paparanga whakamarumaru. He maha ngā mowhiti tautoko ngongo PTFE kua whakatakotoria ki waho o te paparanga whakamarumaru hei ārai i te pa tika i waenga i ngā paipa o roto me waho, me te whakapai ake i te mahi whakamarumaru. Ko ngā pito e rua o te hononga, kia rite ki ngā whakaritenga hononga, ka hoahoahia he hanganga ōrite o te hononga adiabatic diameter nui. Ka whakaritea he pouaka adsorption kī tonu i te tatari ngota 5A ki roto i te hanawiti i hangaia i waenganui i ngā paparanga ngongo e rua hei whakarite kia pai te tohu korehau o te paipa me te roa o te ora korehau i te wā cryogenic. Ka whakamahia te mono hiri mō te atanga tukanga whakakorekore hanawiti.

Rauemi paparanga ārai

Ko te paparanga whakamarumaru he mea tito mai i ngā paparanga maha o te mata whakaata me te paparanga mokowā e takai ana ki te pakitara adiabatic. Ko te mahi matua o te mata whakaata ko te wehe i te whakawhiti wera hihi o waho. Ka taea e te mokowā te aukati i te pa tika ki te mata whakaata, ā, ka mahi hei ārai mura me te ārai wera. Ko ngā rauemi o te mata whakaata ko te pepa konumohe, te kiriata polyester konumohe, me ētahi atu, ā, ko ngā rauemi o te paparanga mokowā ko te pepa muka karāhe kore-kawa, te kakahu muka karāhe kore-kawa, te kakahu nairona, te pepa adiabatic, me ētahi atu.

I roto i te kaupapa hoahoa, ka tīpakohia te pepa konumohe hei paparanga whakamarumaru hei mata whakaata, me te kakahu muka karāhe kore-kawa hei paparanga mokowā.

Pouaka mimiti me te pouaka mimiti

He matū he hanganga moroiti te adsorbent, he nui te horahanga mata adsorption o tōna papatipu kotahi, ā, mā te kaha ngota ka kukume i ngā ngota hau ki te mata o te adsorbent. He mea nui te adsorbent i roto i te hanawiti o te paipa cryogenic ki te whiwhi me te pupuri i te taumata korehau o te hanawiti i te wā cryogenic. Ko ngā adsorbent e whakamahia whānuitia ana ko te sieve ngota 5A me te waro hohe. I raro i ngā āhuatanga korehau me te cryogenic, he rite te kaha adsorption o te sieve ngota 5A me te waro hohe ki te N2, O2, Ar2, H2 me ētahi atu hau noa. He ngāwari te mimiti i te wai i te wa e whakakorengia ana i roto i te hanawiti, engari he ngāwari ki te tahu i roto i te O2. Kāore te waro hohe i whiriwhiria hei adsorbent mō te paipa reo hāora wai.

I tīpakohia te tātari ngota 5A hei ngongo ngongo i roto i te kaupapa hoahoa.
