Pōtae Porowhita Porowhita Rino Hangaia
✧ Whakaahuatanga
Ko te takirere porowhita maitai whakapūmau he takirere mahi-teitei, e whakamahia whānuitia ana i roto i te umanga matū, te hinu, te hau māori, te whakarewa, te hiko me ētahi atu umanga. Ko te takirere porowhita maitai whakapūmau he hanganga kua oti te whakarewa, ā, ko te tinana takirere me te kuaha he mea hanga ki ngā wāhanga maitai whakapūmau. He pai te mahi hiri o te takirere, he kaha te ātete ki te waikura, ā, he roa te ora mahi. He māmā tōna hanganga, he iti te rahi, he ngāwari ki te tāuta me te tiaki. He ngāwari te pana kuaha, ā, ka taea te tapahi katoa i te rere waenga me te kore e turuturu. He whānui te awhe pāmahana o te takirere porowhita maitai whakapūmau me te pēhanga mahi teitei, ā, ka taea te whakamahi mō te whakahaere rere waenga i raro i ngā āhuatanga pāmahana teitei me te pēhanga teitei me te pāmahana iti me te pēhanga teitei.
✧ Ngā Āhuatanga o te Pōtae Porowhita Porowhita Rino Hangaia
1. He māmā ake te hanga me te tiaki nā te mea he māmā ake tōna hanganga i te takirere porowhita.
2. He pai te mahi hiri, ā, he ātete te mata hiri ki te pakaru me te rakuraku. Ina whakatuwheratia, ina katihia te takirere, kāore he paheke i waenganui i te mata hiri o te tinana takirere me te kōpae takirere. Nō reira, he iti noa te pakaru me te haehae, he kaha te mahi hiri, ā, he roa te ora ratonga.
3. Nā te mea he paku noa te whiu kōpae o te takirere aukati ina tuwhera, ina kati hoki, he iti iho tōna teitei i tō te takirere porowhita, engari he roa ake tōna hanganga.
4. He nui te mahi e hiahiatia ana mō te whakatuwheratanga me te kati, he nui te taipana, me te roa o te wā whakatuwheratanga me te kati.
5. He teitei te ātete wai nā te hongere waenga piko o te tinana takirere, ka whai wāhi atu hoki tēnei ki te nui o te whakapaunga mana.
6. Te ahunga rere o te reo I te nuinga o te wā, ka puta te rere whakamua ina iti iho te pēhanga ingoa (PN) i te 16 MPa, me te rere o te reo ki runga mai i te raro o te kōpae takirere. Ka puta te rere whakahē ina neke atu te pēhanga ingoa (PN) i te 20 MPa, me te rere o te reo ki raro mai i te tihi o te kōpae takirere. hei whakapai ake i te mahi a te hiri. Ka taea anake te rere o te reo takirere porowhita i te kotahi te ahunga i te wā e whakamahia ana, ā, kāore e taea te whakarite.
7. Ina tuwhera katoa te kōpae, ka memeha pinepine.
✧ Ngā Painga o te takirere porowhita maitai whakarewa API 602
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 porowhita, 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.
