Me keri tika ngā kōtaha kauhanga whaiti kia kore ai e pakaru te wai.YT28e whakarato ana i te pūngao pānga whakahaeretia, e āhei ai ngā kaiwhakahaere ki te hanga tika i ngā mata o te kauhanga.
Ka whakaitihia e tēnei tika te keri nui, ā, ka whakaitihia hoki ngā utu whakahaere rauemi i muri mai i te tukanga hanga.

E whakahīhī ana tō mātou wheketere ki te whakahaere kounga tino pakari, mai i te whakamahana korehau o ngā wāhanga matua ki te whakamātautau mahi whaihanga-marae o ia keri kua oti. Ka mahi tahi mātou me ngā umanga rangahau ki te whakapai ake i te roa me te whai hua o te hua, me te whakarite kia tutuki i te YT28 ngā paerewa haumaru me te taiao o te ao. Ahakoa mō te keri maina, te tiaki wai, ngā kaupapa kauhanga kawe waka rānei, ka tū te YT28 hei otinga pono e whakataurite ana i te tika, te whai hua, me te whai hua o te utu—he tohu ki tā mātou whakapau kaha ki te hanga mīhini keri toka taumata teitei.
Hei kaihanga ngaio me te neke atu i te 15 tau o te wheako ki ngā mīhini keri toka, ka hangaia e mātou te keri toka waewae-hau YT28 kia tutuki ai ngā tono pakari o te keri whenua me te hanga kauhanga. Ko te taumaha o tēnei taputapu hau-pūngao he 26kg, he kaha pānga ≥70J, ā, ka tautoko i ngā diameter keri mai i te 34mm ki te 45mm me te hohonutanga mōrahi o te 5 mita—he pai mō ngā hanganga toka reo ki te mārō me te tauwehenga pakari ≤6. Mā tōna hanganga kiato me tōna teitei ngāwari ka taea te mahi pai i roto i ngā wāhi whaiti, ā, ka whakaitihia e te pūwero whakauru te parahanga haruru, ka whakapai ake i ngā āhuatanga mahi i te papaanga.
He māmā noa te whakamahi i te YT28 me te piri ki ngā tikanga whakahaere. I mua i te whakamahinga, me horoi e ngā kaiwhakahaere ngā wāhanga o roto hei tango i te hinu ārai-waikura, tirohia te kakau keri mō ngā pakaru, me te whakarite kia kore he ngira wai e āraihia ana hei ārai i te keri maroke. Tīmatahia te mīhini i te pēhanga iti (0.3MPa) mō te whakamātautau 10 meneti, kātahi ka whakanuia mārire te pēhanga hau ki te awhe pai rawa atu 0.5-0.63MPa i te wā e mahi ana. Whakatikatika mārire te pana o te waewae hau i te tīmatanga o te keri kia kore ai e peka te kōhao, ā, whakamahia te pūnaha hononga hau-wai hei pehi puehu whai hua. Whai muri i te mahi, momotuhia te paipa wai i te tuatahi, whakahaerea te mīhini mō te wā poto hei pupuhi i te makuku toenga, ā, rongoatia ki te wāhi haumaru, maroke hei ārai i te waikura.
Kua pūrongohia ngā whakapainga whakamiharo i roto i ngā maina e huri ana mai i ngā keri toka noa ki te YT28. He maha ngā wā kāore i te kaha te whakahaere pānga o ngā keri tuku iho, ka hua ake he 15-20% o te pakarutanga o te wai i roto i ngā kauhanga whaiti, ā, ka piki ake ngā utu whakakore rauemi tae atu ki te 30%. Nā te tere keri iti—ko te tikanga he 0.3-0.5 mita ia meneti i roto i te toka mārō—ka roa ake hoki ngā wā mahi. He rerekē, ka eke te YT28 ki te 0.8-1.2 mita ia meneti i roto i ngā āhuatanga ōrite, ka tapahia te wā keri mā te 40%. Nā tōna whakahaere pānga tika ka whakaitihia te pakarutanga o te wai ki raro iho i te 5%, ā, e toru ngā wā e roa ake ai te mau o ngā wāhanga kakahu i ērā o ngā tauira noa, ka whakaitihia ngā utu tiaki. Hei tāpiri, ka whakaitihia e te kakau whakahaere pokapū me te whakatikatika waewae hau ngāwari o te YT28 te ngenge o te kaiwhakahaere, he amuamu noa mō ngā taputapu tawhito.
