He painga anō tō te hauwai wai mō te rokiroki me te kawe. Ki te whakaritea ki te hauwai, he nui ake te mātotoru o te hauwai wai (LH2) ā, he iti ake te pēhanga e hiahiatia ana mō te rokiroki. Heoi, me -253°C te hauwai kia wai ai, ko te tikanga he tino uaua. Nā te tino iti o te pāmahana me te mōrearea o te mura, ka waiho te hauwai wai hei reo morearea. Nā tēnei take, ko ngā tikanga haumaru tino pakari me te pono teitei he whakaritenga pumau i te wā e hoahoa ana i ngā takirere mō ngā tono e tika ana.

Takirere Velan (Velan)
Ngā whakamahinga o te hauwai wai (LH2).
I tēnei wā, e whakamahia ana te hauwai wai, ā, e ngana ana kia whakamahia i ngā wā motuhake. I roto i te ao rererangi, ka taea te whakamahi hei wahie whakarewatanga rōkete, ā, ka taea hoki te whakaputa ngaru ru i roto i ngā kauhanga hau transonic. I runga i te "pūtaiao nui," kua noho te hauwai wai hei rauemi matua i roto i ngā pūnaha superconducting, ngā whakaterenga matūriki, me ngā taputapu hanumi karihi. I te tipu haere o te hiahia o te tangata mō te whanaketanga tauwhiro, kua whakamahia te hauwai wai hei wahie e te maha atu o ngā taraka me ngā kaipuke i ngā tau tata nei. I roto i ngā horopaki tono i runga ake nei, he tino mārama te hiranga o ngā takirere. Ko te mahi haumaru me te pono o ngā takirere he wāhanga nui o te pūnaha tuku hauwai wai (te whakaputa, te kawe, te rokiroki me te tohatoha). He wero ngā mahi e pā ana ki te hauwai wai. Neke atu i te 30 tau o te wheako mahi me te tohungatanga i roto i te mara o ngā takirere mahi-teitei tae atu ki te -272°C, kua roa a Velan e whai wāhi ana ki ngā kaupapa auaha maha, ā, he mārama kua toa ia i ngā wero hangarau o te ratonga hauwai wai me tōna kaha.
Ngā wero i te wāhanga hoahoa
Ko te pēhanga, te pāmahana me te kukū hauwai he mea nui katoa e tirohia ana i roto i te aromatawai mōrearea hoahoa takirere. Hei whakapai ake i te mahi takirere, he mea nui te hoahoa me te whiriwhiri rauemi. Ka tūtaki ngā takirere e whakamahia ana i roto i ngā tono hauwai wai ki ngā wero anō, tae atu ki ngā pānga kino o te hauwai ki ngā konganuku. I ngā pāmahana tino iti, me tu atu ngā rauemi takirere i te whakaekenga a ngā ngota hauwai (kei te tautohetohe tonu ētahi o ngā tikanga pirau e pā ana i roto i te ao mātauranga), engari me pupuri hoki te mahi noa mō te wā roa i roto i tō rātou huringa ora. Mō te taumata whanaketanga hangarau o nāianei, he iti noa te mōhiotanga o te umanga mō te whakamahinga o ngā rauemi kore-konganuku i roto i ngā tono hauwai. I te wā e whiriwhiri ana i tētahi rauemi hiri, me whai whakaaro ki tēnei mea. Ko te hiri whai hua he paearu mahi hoahoa matua hoki. He rerekētanga pāmahana tata ki te 300°C i waenga i te hauwai wai me te pāmahana taiao (te pāmahana rūma), ka hua ake he pikinga pāmahana. Ka rerekē ngā nekehanga whakawhanui me te whakahekenga wera o ia wāhanga o te takirere. Ka taea e tēnei rerekētanga te arahi ki te turuturu morearea o ngā mata hiri nui. Ko te piri o te hiri o te kakau takirere te arotahi o te hoahoa. Ko te whakawhiti mai i te makariri ki te wera ka puta he rere wera. Tērā pea ka hukapapa ngā wāhanga wera o te kōhao o te taupoki, ka whakararuraru i te mahi hiri o te kakau, ka pā ki te mahi a te takirere. Hei tāpiri, ko te pāmahana tino iti o te -253°C te tikanga me whakamahi te hangarau whakamahana pai rawa atu hei whakarite kia taea e te takirere te pupuri i te hauwai wai i tēnei pāmahana me te whakaiti i ngā ngaronga i puta mai i te kohua. I te mea ka whakawhitia te wera ki te hauwai wai, ka mimiti, ka turuturu. Ehara i te mea koinā anake, ka puta te hauota hāora i te wāhi pakaru o te whakamahana. Ina pā te hāora ki te hauwai, ki ētahi atu mea mura rānei, ka piki ake te mōrearea o te ahi. Nō reira, i te whakaaro ki te mōrearea ahi ka pā ki ngā takirere, me hoahoa ngā takirere me ngā rauemi ātete-pahūtanga, me ngā kaiwhakaoho ātete-ahi, ngā taputapu me ngā taura, me ngā tiwhikete tino pakari. Mā tēnei ka whakarite kia tika te mahi a te takirere mēnā ka puta he ahi. Ko te pikinga o te pēhanga he mōrearea pea ka kore e taea te mahi i ngā takirere. Mēnā ka mau te hauwai wai i roto i te kōhao o te tinana takirere, ā, ka puta te whakawhiti wera me te mimiti hauwai wai i te wā kotahi, ka piki ake te pēhanga. Mēnā he rerekētanga nui o te pēhanga, ka puta te cavitation (cavitation)/haruru. Ka taea e ēnei āhuatanga te arahi ki te mutunga wawe o te ora o te takirere, ā, ka pāngia hoki e ngā mate nui nā ngā hapa o te tukanga. Ahakoa ngā āhuatanga mahi motuhake, ki te taea te whakaaro katoa ki ngā āhuatanga o runga ake nei, ā, ka taea te tango i ngā mahi ārai e rite ana i roto i te tukanga hoahoa, ka taea te whakarite i te haumaru me te pono o te mahi a te takirere. Hei tāpiri, kei reira ngā wero hoahoa e pā ana ki ngā take taiao, pērā i te turuturu rere. He ahurei te hauwai: he iti ngā ngota, kāore he tae, kāore he kakara, ā, he pahū. Mā ēnei āhuatanga ka whakatau te tino take o te kore turuturu.
I te teihana Wai Whakarewa Hauwai o te Tai Hauāuru o Te Tai Tokerau o Las Vegas,
Kei te whakarato ngā miihini o Wieland Valve i ngā ratonga hangarau
Ngā otinga takirere
Ahakoa te mahi me te momo motuhake, me tutuki i ngā takirere mō ngā tono hauwai wai katoa ētahi whakaritenga noa. Kei roto i ēnei whakaritenga: me whakarite te rauemi o te wāhanga hanganga kia mau tonu te hanganga i ngā pāmahana tino iti; Me whai āhuatanga haumaru ahi tūturu ngā rauemi katoa. Mō te take kotahi, me tutuki hoki i ngā wāhanga hiri me te tākai o ngā takirere hauwai wai ngā whakaritenga taketake kua whakahuatia i runga ake nei. He rauemi pai te maitai kore waikura austenitic mō ngā takirere hauwai wai. He kaha pānga pai, he iti te ngaronga wera, ā, ka taea te tu atu i ngā pikinga pāmahana nui. Tērā atu rauemi e tika ana mō ngā āhuatanga hauwai wai, engari he iti noa iho ki ngā āhuatanga tukanga motuhake. Haunga te whiriwhiri rauemi, kaua e warewarehia ētahi taipitopito hoahoa, pērā i te whakaroa i te kakau takirere me te whakamahi i te pou hau hei tiaki i te tākai hiri mai i ngā pāmahana tino iti. Hei tāpiri, ka taea te whakauru i te whakaroa o te kakau takirere ki te mowhiti whakamarumaru hei karo i te haukū. Mā te hoahoa i ngā takirere kia rite ki ngā āhuatanga tono motuhake ka āwhina ki te whakarato i ngā otinga whaitake ake mō ngā wero hangarau rerekē. E rua ngā hoahoa a Vellan mō ngā takirere pūrerehua: ngā takirere pūrerehua nohoanga whakarewa takirua me te takirere pūrerehua nohoanga whakarewa takitoru. He kaha rere rua ngā hoahoa e rua. Mā te hoahoa i te āhua o te kōpae me te ara hurihuri, ka taea te whakatutuki i tētahi hiri piri. Kāore he kōhao i roto i te tinana takirere kāore he toenga reo. Mō te takirere pūrerehua takirua Velan, ka whakamahia te hoahoa hurihuri takirua kōpae, me te pūnaha hiri motuhake VELFLEX, kia tutuki ai te mahi hiri takirere pai rawa atu. Ka taea e tēnei hoahoa patent te tu atu ki ngā huringa pāmahana nui i roto i te takirere. Kei te kōpae takitoru takirua TORQSEAL anō hoki he ara hurihuri motuhake e āwhina ana kia pā noa te mata hiri kōpae ki te nohoanga i te wā e tae atu ai ki te tūranga takirere kati, ā, kāore e rakuraku. Nō reira, ka taea e te taipana kati o te takirere te akiaki i te kōpae kia tutuki ai te nohoanga ōrite, me te whakaputa i tētahi pānga porowhita nui i roto i te tūranga takirere kati, me te hanga i te kōpae kia ōrite te pa ki te porowhita katoa o te mata hiri nohoanga. Mā te ōrite o te nohoanga takirere ka taea e te tinana takirere me te kōpae te whai mahi "whakatikatika-ake", kia kore ai e hopukina te kōpae i te wā e rerekē ana te pāmahana. Ka taea e te rakau takirere kowiri tira whakapakari te mahi i ngā huringa mahi teitei, ā, ka mahi maeneene i ngā pāmahana tino iti. Mā te hoahoa takirua takirua VELFLEX ka taea te mahi tere me te ngāwari o te takirere ipurangi. Nā te whare taha, ka taea te tirotiro, te whakatika rānei i te nohoanga me te kōpae, me te kore e hiahiatia te wetewete i te actuator, ngā taputapu motuhake rānei.
