Ngā Peera Papu Wai Aunoa
He wāhanga nui te peera o te papu wai o te motuka i roto i te pūnaha whakamatao o te waka, he mea nui ki te pupuri i te pāmahana mahi tino pai o te miihini. Hei peera tino tika i hangaia mō ngā tono papu wai o te motuka, ka whakarite kia pai te tuku o te mana mai i te miihini ki te impeller papu wai, ka pā tika ki te whai huatanga o te pūnaha whakamatao me te pono whānui o te miihini.
Mō te whiriwhiri rauemi, ko te whare o te peera rakau papu wai o te motuka he mea hanga i te nairona 66 kua whakapakaritia—he mea whiriwhiri tēnei rauemi nā tōna ātete ki te kakahu, tōna manawanui ki te pāmahana teitei, me ōna āhuatanga mama, e whai wāhi ana ki te roa o te ora o te peera me te whakaiti i te whakapaunga pūngao.
E ai ki te mahi me te hanganga, e toru ngā painga matua o te peera o te papu wai o te motuka, he mea nui tēnei i roto i ngā pūnaha whakamatao o te motuka.
Tuatahi, ko tana mahi matua he tautoko i te pou o te papu wai: ka pupuri pūmau i te pou ki tōna tūranga, me te whakahohe i te hurihuri maeneene, me te tuku pai i te kaha hurihuri mai i te whitiki o te miihini, i te pūnaha taputapu rānei ki te impeller. He mea nui tēnei tuku kia taea ai e te impeller te huri i te wai whakamatao puta noa i te miihini, kia marara ai te wera nui, kia ārai ai hoki i te wera nui.
Tuarua, he hoahoa whakauru te peera—he maha ngā wā ka mīhinihia ngā ara rere i runga i te pou papu wai, ā, kāore e hiahiatia he mowhiti o roto motuhake. Ehara i te mea ka penapena noa i te wāhi tāutanga i roto i te huihuinga papu wai tēnei hoahoa auaha, engari ka whakarei ake hoki i te kaha kawe kawenga o te peera, ka ātete ake ki ngā ahotea miihini e puta ana i te wā e whakahaerehia ana te miihini.
Tuatoru, ka tukuna ēnei peera hei wae hiri kua oti te huihui. Ka whakaratohia e ngā hiri whakauru he ārai pakari ki te whakamatao, te hinu miihini, te puehu, me ētahi atu poke, ka karo i te waikura o te peera me te pakaru wawe i puta mai i te poke o te hinu whakahinuhinu.
Ko ngā āhuatanga matua o ngā peera rakau papu wai o ngā motuka he mea hanga kia tutuki ai ngā whakaritenga pakari o ngā pūnaha whakamatao motuka. Mō ngā rauemi, ko te mowhiti o waho, ngā huānga hurihuri, me ngā mata hono rakau he mea hanga mai i ngā maitai pakari kounga teitei. Ka pāngia ēnei maitai e ngā tukanga maimoatanga wera tino pakari kia eke ki te pakeke teitei, te ātete ki te kakahu, me te kaha o te ngenge, kia taea ai e te peera te tu atu i te hurihuri tere-teitei me ngā pānga miihini mō te wā roa.
Ko ngā hiri ātete-wai matatau tētahi atu āhuatanga tino pai—he mea hanga kia tino tika te mīhini kia piri ki te whare peera me te pou, kia roa ai te wā e ārai ana i te turuturu. Kua hangaia hoki ngā hiri hei whakauru i te whānui me te whakaheke wera i te wā e tīmata ana, e whakamutu ana hoki i te miihini, kia mau tonu ai te whai huatanga o te hiri puta noa i te whānuitanga o te pāmahana.
Hei tāpiritanga, kua pania ngā peera ki te hinu mahi-teitei e tuku ana i te ātete wera, te ātete wai, me te ātete waikura. Mā tēnei hinu motuhake ka whakarite te whakahinuhinu pumau ahakoa i ngā pāmahana mahi teitei, ka whakaiti i te waku me te pakaru i waenga i ngā huānga hurihuri me ngā ara reihi.
Hei whakamutunga, kua tino hangaia te kaha kawenga o ēnei peera kia taea ai te whakahaere i ngā kaha nui o te radial me te axial. Ahakoa ko te kaha radial mai i te kume o te whitiki, ko te kaha axial rānei mai i te mahi a te impeller, kua arotauhia te hanganga o te peera kia tohatohahia ēnei kaha kia ōrite, kia kore ai e kukū te ahotea ā-rohe, kia roa ake ai te ora o te peera.
