Pōtae Porowhita Porowhita Cryogenic mō te -196 ℃
✧ Whakaahuatanga
Ko ngā takirere porowhita cryogenic me ngā taupoki roa kua hangaia mō te mahi i ngā pāmahana iti iho i te -196°C, he mea hanga motuhake hei whakahaere i ngā āhuatanga tino kino o ngā tono cryogenic. Ka whakaratohia e te taupoki roa he whakamarumaru me te tiaki anō mō te kakau takirere me te tākai kia pai ai te mahi i ngā pāmahana iti. He mea whakamahi noa ēnei takirere i roto i ngā ahumahi pēnei i te tukatuka LNG (hau taiao wai), te hanga hau ahumahi, me ētahi atu tono whakahaere wai cryogenic. Ko ngā whakaaro matua mō ngā takirere porowhita cryogenic mō te -196°C ko: Ngā Rauemi: Kua hangaia ēnei takirere mā te whakamahi i ngā rauemi motuhake ka taea te pupuri i tō rātou pono me te mahi i roto i ngā taiao cryogenic. Ko ngā rauemi noa ko te kowiri tira, te maitai waro, me ētahi atu koranu he iti te pāmahana. Te Hiri me te Tākai: Me hoahoa ngā wāhanga hiri me te tākai o te takirere kia mau tonu te whai hua me te ngāwari i ngā pāmahana tino iti hei ārai i te turuturu me te pupuri i te kati pūmau. Te Whakamātautau me te Whakatutuki: Ka whakamatautauria ngā takirere porowhita cryogenic mō ēnei pāmahana iti kia tino pai ai te mahi me te tutuki i ngā paerewa ahumahi mō te ratonga cryogenic. Te Ārai: Ka whakaratohia e te hoahoa potae roa te ārai hei tiaki i ngā wāhanga nui mai i te tino makariri me te karo i te tūponotanga o te hanganga hukapapa ka aukati i te mahi o te takirere. He wāhanga nui ēnei takirere hei whakarite i te whakahaere haumaru me te pono o ngā rere wai cryogenic.
✧ Ngā Āhuatanga o te Pōtae Porowhita Cryogenic mō te -196℃
1. Kua hangaia te taupoki o te takirere kia roa ake te hanganga o te taupoki, ka taea te wehe i te awe o ngā pāpāho pāmahana iti ki te takai, te aukati i te mahi a te hiri taupoki, me te whakatuwhera me te kati ngāwari i te takirere;
2. ka whakamahia e te whakakī he hanganga whakakotahi o te graphite ngāwari, te polytetrafluoroethylene rānei, me te ātete pai ki te pāmahana iti;
3. Ko te hanganga o te takirere pāmahana-iti he whakatuwhera i te kōhao whakaweto i te matua o te takirere. Ko te kapi he mea hanga ki te hiako maitai kore waikura polytetrafluoroethylene, he hanganga takai graphite ngāwari rānei;
4. ina kati te takirere, kia kore ai e piki ake te pāmahana o te reo pāmahana iti i roto i te rūma takirere nā te pāmahana, ka hua ake he pikinga pēhanga rerekē, ka whakaratohia he hanganga whakaora pēhanga ki te taha pēhanga teitei o te kēti, o te tinana takirere rānei;
5. Ko te mata hiri o te mata takirere he carbide sima-kobalt, he iti te whakarerekētanga o te carbide tungsten i te pāmahana iti, he ātete ki te kakahu, ka taea te pupuri i te mahi hiri pai.
Nā te mea ko ngā hua o ngā mea wai pāmahana-iti pērā i te ethylene, te hāora wai, te hauwai wai, te hau māori waikura, te hinu waikura me ētahi atu hua ehara i te mea ka mura, ka pahū noa iho, engari ka whakapūhautia hoki i te wā e whakamahanatia ana, ā, ka rau ngā wā ka whānui haere te rōrahi i te wā e whakapūhautia ana. He mea tino nui te rauemi o te takirere pāmahana-iti, ā, kāore he kounga o te rauemi, ka puta ai te turuturu o waho, te turuturu rānei o roto o te anga me te mata hiri; kāore e taea e ngā āhuatanga miihini whānui, te kaha me te maitai o ngā wāhanga te whakatutuki i ngā whakaritenga o te whakamahinga, te pakaru rānei; ka hua ake te turuturu o te reo hau māori waikura nā te pahūtanga. Nō reira, i roto i te tukanga whakawhanake, hoahoa me te whakawhanake i ngā takirere pāmahana-iti, ko te maimoatanga rauemi te take matua.
✧ Ngā Painga o te Pōtae Porowhita Cryogenic mō te -196℃
I te wā e whakatuwheratia ana, e kati ana hoki te takirere porowhita maitai hanga, nā te mea he iti ake te waku i waenga i te kōpae me te mata hiri o te tinana takirere i tērā o te takirere kuaha, ka ātete ki te kakahu.
He poto noa te whiu whakatuwheratanga, te whiu kati rānei o te kakau takirere, ā, he tino pono te mahi tapahi, ā, nā te mea he rite te huringa o te putanga nohoanga takirere ki te whiu o te kōpae takirere, he tino pai mō te whakatikatika i te tere rere. Nō reira, he tino pai tēnei momo takirere mō te tapahi, te whakahaere rānei me te whakawhāiti.
