Ngā takirere porowhitakua noho hei pou matua mō te whakahaere wai mō ngā tau 200, ā, kei ngā wāhi katoa inaianei. Heoi, i ētahi whakamahinga, ka taea hoki te whakamahi i ngā hoahoa takirere porowhita hei whakahaere i te kati katoa o te wai. Ko ngā takirere porowhita te nuinga o te wā e whakamahia ana hei whakahaere i te rere o te wai. Ka kitea te takirere porowhita whakakā/whakaweto me te whakamahinga whakarerekē i te taha o waho o ngā whare me ngā hanganga pakihi, kei reira ngā takirere e whakanohoia pinepinetia ana.

He mea nui te mamaoa me te wai ki te Huringa Ahumahi, engari me ārai ēnei matū kino pea.takirere porowhitaKo te takirere tuatahi tēnei e hiahiatia ana hei whakaoti pai i tēnei mahi. Nā te angitu me te rongonui o te hoahoa takirere porowhita, i ārahi ai te nuinga o ngā kaihanga takirere tuku iho nui (Crane, Powell, Lunkenheimer, Chapman, me Jenkins) ki te whiwhi i ā rātou pateni tuatahi.

Ngā takirere ketie whakaarohia ana kia whakamahia i ngā tūranga tuwhera katoa, i ngā tūranga kati katoa rānei, engari ka taea te whakamahi i ngā takirere porowhita hei takirere poraka, hei takirere wehe rānei, engari kua hangaia kia tuwhera ā-wāhanga hei whakahaere i te rere i te wā e whakahaeretia ana. Me tūpato i roto i ngā whakatau hoahoa ina whakamahi ana i ngā takirere porowhita mō ngā takirere wehe me ngā takirere whakaweto, nā te mea he uaua ki te pupuri i te hiri piri me te pana nui ki te kōpae. Mā te kaha o te wai ka āwhina ki te whakatutuki i te hiri pai, ā, ka māmā ake te hiri ina rere te wai mai i runga ki raro.

He tino pai ngā takirere porowhita mō ngā tono takirere whakahaere nā te mea he mahi whakahaere, e āhei ai te whakahaere tino pai me ngā tūnga me ngā kaiwhakaoho e hono ana ki te taupoki me te kakau o te takirere porowhita. He tino pai rātou i roto i te maha o ngā tono whakahaere wai, ā, e kiia ana i roto i ēnei tono ko "Ngā Huānga Whakahaere Whakamutunga."

ara rere ā-kore

E mōhiotia ana hoki te Porowhita ko te takirere porowhita nā tōna āhua porowhita taketake, e huna tonu ana i te āhua rerekē me te uaua o te ara rere. Nā te mea he nikau ōna awa o runga me o raro, ka kitea tonutia e te takirere porowhita tuwhera katoa te waku nui, te ārai rānei i te rere o te wai, he rerekē ki te kuaha tuwhera katoa, ki te takirere pōro rānei. Ka whakaroa te waku wai i puta mai i te rere whakarara i te takirere.

Ko te tauwehenga rere, "Cv" rānei, o tētahi takirere ka whakamahia hei tatau i te rere i roto. He tino iti te ātete rere o ngā takirere kēti ina tūwhera, nō reira ka tino rerekē te Cv mō tētahi takirere kēti me tētahi takirere porowhita he rite te rahi.

Ka taea te hanga i te kōpae, i te mono rānei, e mahi ana hei tikanga kati mō te takirere porowhita, ki ngā momo āhua rerekē. Ka taea te whakarerekē nui i te tere rere i roto i te takirere i runga i te maha o ngā hurihanga o te kakau ina tuwhera te takirere mā te whakarerekē i te āhua o te kōpae. Ko te hoahoa kōpae piko "tūturu" ake, e whakamahia ana i te nuinga o ngā tono nā te mea he pai ake i ētahi atu hoahoa ki tētahi nekehanga motuhake (hurihuri) o te kakau takirere. He tika ngā kōpae V-port mō ngā rahi katoa o ngā takirere porowhita, ā, kua hangaia mō te aukati rere pai puta noa i ngā ōrau whakatuwheratanga rerekē. Ko te whakahaere rere tino te whāinga o ngā momo ngira, heoi he maha ngā wā ka tukuna noa iho i roto i ngā diameter iti ake. Ka taea te whakauru i tētahi whakaurunga ngohengohe, pakari ki roto i te kōpae, i te nohoanga rānei ina hiahiatia te kati katoa.

Whakapaipai takirere porowhita

Ko te katinga tūturu o ngā wāhanga ki ngā wāhanga i roto i te takirere porowhita e whakaratohia ana e te pōro. Ko te nohoanga, te kōpae, te kakau, te nohoanga o muri, me ētahi wā ko ngā taputapu e hono ana i te kakau ki te kōpae e hanga ana i te whakapaipai o te takirere porowhita. Ko te pai o te mahi me te roa o te ora o tētahi takirere e whakawhirinaki ana ki te hoahoa whakapaipai me te kōwhiringa rauemi, engari he ngoikore ake ngā takirere porowhita nā te nui o te waku wai me ngā huarahi rere uaua. Ka piki ake te tere me te pōrearea i te whakatata o te nohoanga me te kōpae ki a rātou anō. Nā te āhua waikura o te wai me te tere piki ake, ka taea te kino i te whakapaipai takirere, ka nui ake te turuturu o te takirere ina kati. Ko te aho te kupu mō te hapa e puta ana i ētahi wā he maramara iti i runga i te nohoanga, i te kōpae rānei. Ko te mea i tīmata hei ara turuturu iti ka tipu pea ka huri hei turuturu nui mena kāore e whakatikahia i te wā tika.

Ko te mono takirere o ngā takirere porowhita parahi iti ake he mea hanga i te rauemi kotahi ki te tinana, i ētahi wā he koranu parahi pakari ake. Ko te rauemi porowhita tino noa mō ngā takirere porowhita rino maka he parahi. Ko te IBBM, ko te "Tinana Rino, Whakapiri Parahi" rānei, te ingoa o tēnei whakapaipai rino. He maha ngā momo rauemi whakapaipai e wātea ana mō ngā takirere maitai, engari he maha ngā wā ka hangaia tētahi, neke atu rānei ngā huānga whakapaipai ki te maitai kore waikura martensitic raupapa 400. Hei tāpiri, ka whakamahia ngā rauemi mārō pēnei i te stellite, ngā maitai kore waikura raupapa 300, me ngā koranu parahi-nikora pēnei i te Monel.

E toru ngā momo matua mō ngā takirere porowhita. Ko te āhua "T", me te kakau e tū poutū ana ki te rere o te paipa, te mea tino kitea.
;
He rite ki te takirere-T, ka hurihia e te takirere koki te rere i roto i te takirere 90 nekehanga, hei taputapu whakahaere rere me te tuke paipa 90 nekehanga. I runga i ngā "rākau Kirihimete" hinu me te hau, ko ngā takirere porowhita koki te momo takirere whakahaere putanga whakamutunga e whakamahia tonutia ana i runga i ngā poiha.
;
Ko te hoahoa "Y", koinei te tuatoru o ngā hoahoa, i hangaia hei whakau i te hoahoa mō ngā tono whakaweto/whakakā, me te whakaiti i te rere pōrearea e puta ana i roto i te tinana o te takirere porowhita. Ko te taupoki, te kakau, me te kōpae o tēnei momo takirere porowhita kua kokihia ki te koki 30-45 nekehanga kia tika ake ai te ara rere, kia whakaitihia ai hoki te waku wai. Nā te iti o te waku, kāore te takirere e pāngia e te kino o te wai, ā, kua pai ake ngā āhuatanga rere whānui o te pūnaha paipa.
