Takirere Pōro Whakahaere Whakahohe Hiko
✧ Whakaahuatanga
HikowhakahaereHe mea hanga te takirere pōro i te whakaoho hiko me te takirere pōro. He wāhanga pēhanga paipa mō te whakahaere tukanga aunoa ahumahi, e whakamahia ana mō te whakatuwhera me te kati mamao (whakaweto me te whakaweto) o ngā pāpāho paipa. Ko ngā wāhanga whakatuwhera me te kati (porowhita) ka peia e te kakau takirere, ka hurihuri i te tuaka o te kakau takirere. Ko te nuinga o te whakamahinga he tapahi, he hono rānei i te reo i roto i te paipa, ā, ka taea hoki te whakamahi mō te whakatikatika me te whakahaere i te wai. Ko te matua pōro āhua-V o te takirere pōro āhua-V hiri pakari he kaha kutikuti kaha i waenga i te matua pōro āhua-V me te nohoanga whakarewa o te mata o te karawiti sima, inā koa mō te reo kei roto te muka me ngā matūriki totoka iti. Ka wehea te takirere pōro hiko ki te takirere pōro flange hiko, te takirere pōro rawhi hiko, te takirere pōro whakarewa hiko, te takirere pōro waea hiko. E ai ki te āhua hiri, ka wehea hoki ki te takirere pōro hiko hiri ngohengohe, te takirere pōro hiko hiri pakari.

✧ Ngā Āhuatanga o te Takirere Pōro Whakahaere Whakaoho Hiko
1. He iti te ātete wai, ā, he ōrite tōna tauwehenga ātete ki tērā o te wāhanga paipa o te roa ōrite.
2. Hanganga māmā, rahi iti, taumaha māmā.
3. He pūmau, he pono hoki, he pai te hiri, kua whakamahia whānuitia hoki i roto i ngā pūnaha korehau.
4. He ngāwari ki te whakahaere, he tere te whakatuwhera me te kati, mai i te tuwhera katoa ki te kati katoa, kia 90 nekehanga te hurihanga, he ngāwari ki te whakahaere mamao.
5. He ngāwari te tiaki, he māmā te hanganga o te takirere pōro, he kaha te mowhiti hiri i te nuinga o te wā, he watea ake te wetewete me te whakakapi.
6. Ina tuwhera katoa, ina kati katoa rānei, ka wehea te mata hiri o te pōro me te nohoanga mai i te reo, ā, e kore te reo e pakaru te mata hiri o te takirere ina haere.
7. He whānui ngā whakamahinga, he iti te diameter ki te torutoru mirimita, he nui ki te torutoru mita, mai i te korehau teitei ki te pēhanga teitei ka taea te whakamahi.
E ai ki te tūranga o te awa, ka taea te wehewehe i te takirere pōro papa teitei ki te tika, te toru-ara me te koki-matau. Ko ngā takirere pōro whakamutunga e rua e whakamahia ana hei tohatoha i te reo me te whakarerekē i te ahunga rere o te reo.
✧ Ratonga Whai Muri i te Hoko
He mea tino nui te ratonga muri-hoko o te Electric Actuator Control Ball Valve, nā te mea ko te ratonga muri-hoko wā-tūturu me te whai hua anake ka taea te whakarite kia roa te mahi me te pumau. Ko ngā mea e whai ake nei ko ngā ihirangi ratonga muri-hoko o ētahi o ngā valve pōro mānu:
1. Tāutanga me te whakatūnga: Ka haere ngā kaimahi ratonga muri-hoko ki te pae ki te tāuta me te patuiro i te takirere pōro mānu hei whakarite kia pumau, kia noa hoki tana mahi.
2. Tiaki: Me tiaki tonu te takirere pōro mānu kia pai ai te mahi, kia iti ai hoki te tere o te rahunga.
3. Te Whakatau Rapanga: Mena ka rahua te takirere pōro mānu, ka whakahaerehia e ngā kaimahi ratonga muri-hoko te whakatau raruraru i runga i te papaanga i roto i te wa poto rawa atu hei whakarite kia mahi noa.
4. Whakahoutanga me te whakapai ake i te hua: Hei whakautu ki ngā rauemi hou me ngā hangarau hou e puta ake ana i te mākete, ka tūtohu wawe ngā kaimahi ratonga muri-hoko i ngā otinga whakahou me te whakapai ake ki ngā kiritaki kia pai ake ai ngā hua takirere.
5. Whakangungu Mātauranga: Ka whakaratohia e ngā kaimahi ratonga muri-hoko he whakangungu mātauranga takirere ki ngā kaiwhakamahi hei whakapai ake i te taumata whakahaere me te tiaki o ngā kaiwhakamahi e whakamahi ana i ngā takirere pōro mānu. I roto i te poto, me whakamana te ratonga muri-hoko o te takirere pōro mānu i ngā taha katoa. Mā tēnei anake ka taea ai e ngā kaiwhakamahi te kawe mai i tētahi wheako pai ake me te haumaru hoko.
