Mā te tika i inehia i roto i ngā maikorona ka taea te whakarite kia tukuna te hiko i roto i ngā megawatts.
I te ao o te pūngao hou, ko te hiko wai te tūāpapa o te whakaputa hiko pono. Kei muri i ngā tāpine nui me ngā kaihanga hiko e whakamahi ana i te hiko wai kei reira tētahi toa rongonui: te miihini Mana Tau Rorohiko (CNC). Kua noho tēnei hangarau hanga matatau hei mea nui ki te whakaputa i ngā wāhanga uaua e taea ai te whakamahi i te hiko wai, mai i ngā oma tāpine nunui ki ngā pou me ngā pūnga tika.
Ka taea e ngā mīhini CNC te whakatutuki i ngā āheinga kia piri ki te 4 maikiromita—tata ki te rohe e hiahiatia ana mō ngā wāhanga hiko wai nui—kia pai ai te huihuinga me te mahi tino pai o ngā taputapu e mahi ana i raro i ngā pēhanga waipēhi nui.
01. Te Hurihanga o te Hanganga Wāhanga Turbine
Ko te ngākau o tētahi pūnaha hiko wai ko tana tāpine, ā, kua hurihia e te miihini CNC te hanga o ēnei wāhanga nui. Ko ngā oma tāpine wai, inā koa ko ērā mō ngā tāpine Francis me Kaplan, he mata whakairo matatini, me piri ki ngā kōtaha wai-ā-tinana tika hei whakanui ake i te pai o te huringa pūngao.
Kāore e taea e ngā tikanga hanga tuku iho e uru ana ki te "maka onepu - huri ā-ringa - tirotiro tauira ahu" te whakamana i te tika me te kounga o ēnei mata matatini.
Nā te whakaurunga o te mīhini CNC tukutahi e rima-tuaka kua whakatikahia ēnei herenga. Mā tēnei hangarau ka taea te mīhini katoa o ngā mata tāpine nui i roto i te whakaritenga kotahi, me te pupuri i te tika o te kōtaha mata i roto i te 0.02mm/m—he whakatakotoranga nui hei whakarite i te pai o te tāpine me te pumau o te mahi.
Mō ngā wāhanga nunui pēnei i ngā pouaka tāpine me ngā pou, ka taea te tae ki te diameter o te 42 putu me te taumaha neke atu i te 350 tāne, ko ngā mīhini CNC anake te tikanga hanga e taea ana. Nā te kaha ki te whakahaere i aua wāhanga nunui me te pupuri tonu i te tika, he mea nui rawa atu ēnei i roto i te hanga hiko wai.
02. Kei tua atu i ngā Turbines: Ngā tono hiko wai whānui
Ko ngā whakamahinga o te miihini CNC i roto i te hiko wai he whānui atu i te hanga tāpine. He mea nui te mahi a te hangarau ki te hanga i ngā tāpua me ngā kēti teihana hiko, e hiahia ana kia tika te whakahaere i ngā āhuatanga kia pai ai te mahi i raro i te pēhanga wai nui.
Kua whakapūmautia e ngā kamupene pēnei i a Voith Hydro ngā tūāpapa CNC puta noa i ā rātou whare hanga, ā, kua hangaia he pūnaha hanga kotahi e āhei ai ngā kaiwhakahaere ki te whakahaere pai i ngā mīhini maha. Nā tēnei whakapūmautanga kua tino whakaitihia ngā wā tiaki me te whakapai ake i te ngāwari o te hanga.
Mā te hangarau nei ka taea te tiaki me te whakatika i ngā taputapu hiko wai o nāianei me te tino tika. Ka taea e ngā mīhini CNC motuhake te whakahoki i ngā wāhanga kua tawhito ki ō rātou whakaritenga taketake, ka roa ake te ora o te mahi, ā, ka karohia te utu o te whakakapinga katoa.
03. Ngā Pūkenga Hangarau e Ārahi ana i te Whakatairanga i te Pūngao Wai
Nā te whanaketanga o te hangarau CNC kua taea tika te whakapai ake i te pai me te pono o te hiko wai. Mā te miihini CNC maha-tuaka ka taea e ngā kaihanga te whakaputa i ngā wāhanga me ngā āhuahanga uaua e kore e taea e ngā tikanga tuku iho.
Kei roto i ngā pūnaha CNC hou ngā hangarau whakatauira e hanga ana i ngā māhanga matihiko o te tukanga mīhini. Ka tautuhia e ēnei whakatauira ngā tukinga pea i waenga i ngā taputapu, ngā wāhanga mahi, me ngā taputapu i mua i te tīmatanga o te tapahi, ka ārai i ngā hapa utu nui, ka whakaiti hoki i te wā tatūnga.
Kua tino angitu ngā kaihanga Hainamana i tēnei mara. Kua whakawhanakehia e ngā kamupene pēnei i a Kede CNC ngā pokapū miihini poutū e rima-tuaka, tae atu ki te tauira KMC1250 i hangaia mō te hanga wāhanga hiko wai.
Ka taea e ēnei mīhini matatau te mahi i ngā mahi hanga me ngā mahi whakatika tino tika i ngā takirere nui, i ngā keti, i ngā wehenga paipa rino pehanga, me ētahi atu taputapu hiko wai.
Nā te whakaurunga o ngā pūnaha CAD/CAM ki te mīhini CNC kua māmā ake te tukanga whakaputa. Ka rere pai ngā raraunga hoahoa mai i te hangarau ki te hanga, ka whakaiti i ngā hapa whakamāori me te whakateretere i ngā wā whakaputa.
He mea tino whai hua tēnei miro matihiko mō te hiko wai, ina hangaia te nuinga o ngā wāhanga mō ngā kaupapa motuhake, kaua mō te hanga papatipu.
