Pito Whakarewa o te Takirere Kēti Rino
✧ Whakaahuatanga
He mea whakamahi noa ngā takirere kuaha maitai hanga i roto i ngā mahi ahumahi nā te mea he pakari te hanganga me te kaha ki te tu atu ki ngā āhuatanga pēhanga me te pāmahana teitei. He mea pai ake ēnei mō ngā mahi i roto i te umanga hinu me te hau, ngā tipu hiko, me ngā tipu hinu-matū. Anei ētahi āhuatanga matua me ngā painga o ngā takirere kuaha maitai hanga: Kaha me te Pakari: Ka hangaia ngā takirere kuaha maitai hanga mā te whakamahi i te tukanga hanga, e tino kaha ai, e ātete ai hoki ki ngā ahotea miihini. Nā tēnei ka pai ai mō ngā taiao uaua e tino hiahiatia ana te pakari. Ātete ki te Pēhanga Teitei me te Pāmahana: Kua hangaia ēnei takirere hei whakahaere i ngā mahi pēhanga teitei me te pāmahana teitei, e whakarato ana i te otinga whakahaere rere pono i roto i ngā āhuatanga mahi uaua. Ngā Āhuatanga Hiri Pai: He pai ngā āhuatanga hiri, e ārai ana i te turuturu ina kati te takirere. He mea nui tēnei hei pupuri i te pono o te pūnaha me te ārai i te ngaronga o te wai. Te Ngaronga Pēhanga Iti: Ina tuwhera katoa, ka tukuna e ngā takirere kēti maitai hanga he iti noa te ngaronga pēhanga, ka taea ai te whakahaere pai i te rere me te whakaiti i te whakapaunga pūngao. Te Rerekētanga: He pai mō te whānuitanga o ngā wai, ka taea ai te whakamahi mō ngā tono ahumahi. Te Whakatutuki i ngā Paerewa: He maha ngā wā ka hangaia, ka hangaia hoki ngā takirere kēti maitai hanga kia rite ki ngā paerewa ahumahi, kia tika ai te pono me te mahi haumaru. I te nuinga o te wā, ka whakanuia ngā takirere kēti maitai hanga mō tō rātou kaha, te roa, te ātete ki te pēhanga teitei me te pāmahana, ngā āhuatanga hiri pai rawa atu, me te rerekētanga, ka waiho hei whiringa pai i roto i ngā tautuhinga ahumahi uaua.
✧ Ngā Āhuatanga o te takirere kēti maitai whakarewa API 602
1. He māmā ake te hanganga i te takirere kuaha, ā, he watea ake te hanga me te tiaki.
2. Kāore te mata hiri e ngāwari ki te mau, ki te rakuraku, ā, he pai te mahi hiri. Kāore he reti tata i waenga i te kōpae takirere me te mata hiri o te tinana takirere ina whakatuwheratia, ina kati rānei, nō reira kāore te mau me te rakuraku e kino, he pai te mahi hiri, ā, he roa te ora ratonga.
3. He iti te whiu o te kōpae ina whakatuwheratia, ina kati hoki, nō reira he iti ake te teitei o te takirere aukati i te takirere keti, engari he roa ake te roa o te hanganga i te takirere keti.
4. He nui te taipana whakatuwheratanga me te katinga, he uaua te whakatuwheratanga me te katinga, ā, he roa te wā whakatuwheratanga me te katinga.
5. He nui te ātete wai, nā te mea he pōturi te hongere reo i roto i te tinana takirere, he nui te ātete wai, ā, he nui te whakapaunga hiko.
6. Te ahunga rere o te reo Ina te pēhanga ingoa PN ≤ 16MPa, ka rere whakamua te reo, ka rere whakarunga mai i raro i te kōpae takirere; ina te pēhanga ingoa PN ≥ 20MPa, ka rere whakamuri te reo, ka rere whakararo mai i runga i te kōpae takirere. Hei whakanui ake i te mahi a te hiri. Ina whakamahia, ka taea anake te rere o te reo takirere porowhita i te kotahi ahunga, ā, kāore e taea te whakarerekē i te ahunga rere.
7. Ka memeha te kōpae ina tuwhera katoatia.
✧ Ngā Painga o te takirere kēti maitai whakapūmau 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 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.
