Ko ngā tāwhana waipēhi te ngākau o ngā tipu hiko waipēhi, e huri ana i te kaha nekeneke me te kaha o te wai e rere ana hei hurihanga ā-mīhini, ā, mā tēnei ka akiaki i ngā kaihanga hiko ki te whakaputa hiko. I a te ao e rapu ana i ngā puna hiko pumau me te pono, kua nui ake te hiranga o te hoahoa me te hanga i ēnei mīhini matatau. Ka rukuhia e tēnei tuhinga te tukanga uaua o te kawe mai i tētahi tāwhana waipēhi mai i te ariā ki te ao tūturu.
Wāhanga 1: Te Wāhanga Hoahoa – Te Wāhi e Tūtaki ai te Hangarau ki te Taiao
He mahi uaua, he maha ngā kaupapa ako te hoahoa o tētahi tāpine waipēhi e whakataurite ana i ngā mahi wai, te pūtaiao rauemi, te miihini hanganga, me ngā whakaaro taiao. Ka tīmata mā te pātai matua: He aha te momo tāpine e pai ana mō te papaanga?
1.1 Kōwhiringa Tāpine: Te Whakataurite i te Mīhini ki te Rauemi
Ko te kōwhiringa o te tāpine ka whakawhirinaki ki te tihi o te papa (te teitei o te wai e heke ana) me te tere o te rere.
Ngā Tāpine Whakaohooho (Wīra Pelton): He pai mō ngā mahi rere-teitei, rere-iti. I roto i te tāpine Pelton, ka pā ngā pupuhi wai tere-teitei ki ngā peere āhua-pūnu e mau ana ki runga i te oma, ka whakawhiti i te nekehanga. Ko te arotahi o te hoahoa ki te arotau i te āhua o te peere hei hopu i te kaha mōrahi mai i te tāpine.
Ngā Tāpine Tauhohenga: Whakamahia te tere me te pēhanga o te wai. Ka rumakina ēnei ki te rere o te wai.
Pūwero Francis: Ko te hoiho mahi o te hiko wai, e tika ana mō te whānuitanga rere-waenga, rere-waenga. Kei roto i tōna hoahoa he oma rere-whakauru me ngā vane ārahi pumau (ngā vane noho) me ngā kuaha wicket ka taea te whakarite hei whakahaere i te rere. Ko te āhua matatini, miro o ōna mata he mea whakamiharo o te hangarau waipēhi.
Ngā Tāpine Kaplan me ngā Porowhita: I hangaia mō ngā wāhi rere-rahi, iti te pane. He tāpine rere-axial ēnei, he rite ki te porowhita o te kaipuke. Ko te āhuatanga matua o te tāpine Kaplan ko ōna mata, ka taea te whakarite i te wā e whakahaerehia ana (whakahaere-rua) kia mau tonu te pai o te mahi i raro i ngā āhuatanga rere rerekē.
1.2 Te Tukanga Hoahoa Mamati
Ko te hoahoa o ngā tāpine hou e tino whakawhirinaki ana ki ngā pūmanawa matatau me ngā taputapu whakatauira.
Te Aromatawai Wai Rorohiko (CFD): He mea nui te CFD. Ka hangaia e ngā kaihangarau he tauira 3D mariko o te tāpine, ka whakatauira i te rere o te wai i roto. Mā tēnei ka taea e rātou te tātari i te tohatoha pēhanga, te tautuhi i ngā mōrearea o te cavitation (te hanganga o ngā mirumiru kohu ka kino pea ngā mata), me te arotau i ngā āhua o te mata mō te tino whai huatanga me te hopu pūngao i mua noa atu i te tapahi i tētahi konganuku.
Tātari Huānga Mutunga Kore (FEA): Ahakoa ko te CFD te kaiwhakahaere o te wai, ko te FEA te kaiwhakahaere o te hanganga. Ka whakatauira tēnei pūmanawa i ngā ahotea miihini, ngā wiri, me ngā whakarerekētanga o ngā wāhanga tāpine i raro i ngā kawenga waipēhi tino nui. Ka whakarite kia taea e te kaiārahi, te pou, me te anga te tu atu i ngā tekau tau o te mahi me te kore e pakaru.
Whakamātautau Tauira: Ahakoa ngā pūmanawa matatau, kei te hangaia tonutia, kei te whakamatautauria hoki ngā tauira tauine ā-tinana (i te nuinga o te wā 1:5 ki te 1:10) i roto i ngā taiwhanga motuhake. Ka whakamahia ngā raraunga mai i ēnei tauira hei whakamana me te whakapai ake i ngā whakatauira mamati, hei whakaū whakamutunga i ngā taurangi mahi.
Wāhanga 2: Te Wāhanga Whakaputa – Mai i ngā Rauemi Mata ki te Wāhanga Mana
Kia oti te hoahoa te whakatau me te whakamana, ka tīmata te tukanga hanga tino tupato.
2.1 Kōwhiringa Rauemi
Ka mahi ngā wāhanga tāpoi i roto i te taiao uaua o te pēhanga teitei, te horo, me te pea ka pakaru. Ko te rauemi matua he maitai kore waikura martensitic (hei tauira, CA6NM, 13/4 rānei), i whiriwhiria mō tōna huinga pai o te kaha, te pakari, me te ātete ki te waikura.
2.2 Ngā Tukanga Hanga Matua
Te Maka: Ko ngā wāhanga nunui pēnei i te oma, te anga, me ngā mowhiti pumau ka hangaia mā te maka. Ka ringihia te maitai whakarewa ki roto i ngā pokepoke onepu uaua hei hanga i ngā wāhanga tata ki te āhua kupenga. Me tino tika tēnei tukanga kia kore ai e hapa ka noho hei wāhi pakaru.
Te Hanga: Ko ngā wāhanga nui pēnei i te pou matua, e tuku ana i te taipana nui, ka hangaia i te nuinga o te wā. Ka whakataurite te hanga i te hanganga o te konganuku, ka hua ake he āhuatanga miihini pai ake me te ātete ki te ngenge.
Te Mīhini (CNC): He āhua taratara ngā wāhanga whakarewa me ngā wāhanga hanga e hiahia ana kia tino tika te mīhini. Ka whakamahia ngā mīhini Mana Tau Rorohiko (CNC) hei mira, hei huri, hei keri hoki i ngā wāhanga ki ō rātou rahinga whakamutunga me ngā āheinga kia piri ki te haurua o te mirimita. He mea tino nui tēnei mō ngā mata o te oma, ina pā tika te mutunga o te mata me te āhuahanga ki te whai huatanga.
Whakarewa: He nui rawa ngā tāpine nui hei whakarewa, hei hanga rānei hei wāhanga kotahi. Ka whakarewahia ngā wāhanga iti e ngā kaiwhakarewa whaimana mā te whakamahi i ngā tukanga aunoa, karetao rānei. Hei tauira, he maha ngā wā ka hangaia he oma Francis mā te whakarewa i ngā mata takitahi ki runga i te karauna me te whitiki. He mea nui te maimoatanga wera i muri i te whakarewa hei whakamama i ngā ahotea toenga.
2.3 Te Mana Kounga me te Whakaoti
He mea nui te whakapūmau kounga i ia taumata.
Whakamātautau Kore-Whakangaro (NDT): Ka whakamahia ngā tikanga pēnei i te Whakamātautau Ultrasonic (UT) me te Tirotiro Whakauru Tae (PT) hei kimi i ngā hapa o roto, o te mata rānei o ngā whakarewa me ngā mea whakarewa.
Te Whakataurite: Ka pāngia te oma kua huihui e te whakataurite hihiri tino tika. Ka taea e te kore taurite te whakaputa wiri kino i ngā tere mahi. Ka mirohia te oma i roto i te mīhini whakataurite, ā, ka tāpirihia, ka tangohia rānei he iti noa ngā rauemi kia tino maeneene te hurihuri.
Paninga: Hei whakapakari i te ātete ki te horo me te pirau, ka taea te pani i ngā wāhi tino nui o te oma, inā koa ko ngā taha o mua o ngā mata, ki ngā rauemi mata mārō, ki ngā whakakikorua kowiri tira rānei.
Te Ao o te Ao: Ngā Auahatanga o te Hoahoa me te Hanga o ngā Turbine
Kei te whanake tonu te ahumahi, e peia ana e ngā hiahia mō te ngāwari, te atawhai ki te taiao, me te whai huatanga utu.
Māhanga Mamati: Ko te hanga i tētahi tauira mariko o tētahi tāpine tūturu ka taea te aroturuki i te wā-tūturu, te tiaki matapae, me te arotau i te mahi puta noa i tōna huringa ora.
Te Hanga Tāpiri (Tānga 3D): Ahakoa kāore anō kia whakamahia mō ngā mīhini tānga tauine-katoa, kei te hurihia e te tānga 3D te hanga o ngā tauira matatini, ngā tauira whakarewa haumi, me ngā wāhanga whakakapinga, e whakaiti ana i ngā wā arahi.
Ngā Hoahoa e Pai ana mō ngā Ika: Kei te piki haere te aro ki te hoahoa i ngā tāpine e taea ai te haere haumaru o ngā ika, me ngā āhuahanga kua whakarerekētia me ngā tere hurihuri puhoi ake hei whakaiti i ngā whara.
Hangarau Tere-Rērere: Kei te hangaia ngā tāpine hou, inā koa i roto i ngā wāhi rokiroki papu, kia whakahaerehia i ngā tere rerekē, kia taea ai e rātou te arotau i te whai huatanga puta noa i te whānuitanga o ngā putanga hiko me te whakarato i te pumau pai ake o te whatunga hiko.
