Ngā whakatūpato mō te tāutanga o te pēhi hau tīwiri me ngā paipa

1. Ngā tikanga tāutanga mō ngā pūwero hau tīwiri

1) Ngā whakaaro mō ngā paipa pūwero tīwiri Me hanga te turanga ki runga i te papa mārō, ā, me whakataurite te papa o te turanga i mua i te tāutanga hei karo i te wiri e puta mai ana i te pūwero.

2) He iti te wiri e puta mai ana i te pūwero hau tīwiri, nō reira kāore he take ki te whakatika i te turanga. Heoi, me papatahi te whenua e whakatakotoria ana, ā, kaua te whenua o raro e waiho hei oneone ngohengohe. He pai ake te whakatakoto i te 5-10 mm o te urunga ngohengohe, o te urunga mimiti wiri rānei ki raro o te pūwero hei ārai i te wiri me te haruru.

3) Mena kei runga ake i te whare te pūwero hau tīwiri, me mahi tēnei hei ārai i te wiri kei tukuna ki raro, hei hanga rānei i te haruru, ka tū hei mōrearea mō te haumaru o te pūwero me te whare tonu.

2, Ngā hononga paipa hau mō ngā paipa hau i roto i ngā pūnaha pēhi hau

1) Ina whakapūpūhia te paipa matua, me piko te paipa ki te 1 ~ 2 nekehanga hei whakahaere i te tukunga o te wai kua whakakōkīhia ki roto i te paipa. Kaua te whakahekenga pēhanga o te paipa tohatoha e neke ake i te 5% o te pēhanga kua whakaritea o te pūwero, nō reira he pai ake te whiriwhiri i te diameter paipa nui ake i te wā tohatoha.

2) Me hono te paipa peka mai i te tihi o ngā pūtake hiko hei karo i te mimiti o te wai i roto i ngā pūtake hiko ki te mīhini mahi, ā, ko te mea pai ko te paipa putanga hau kōpeke me whai takirere kotahi te ara.

3) Me tāuta ngā takirere pōro ki te pito o te ara tirotiro hei whakahaere i te tukunga o te hauhautanga.

4) Kaua te raina matua e whakaitihia noatia, ā, ki te mea me whakaiti, me whakanui rānei, me whakamahi he paipa whakaiti, ki te kore ka rerekē te rere o te hiko i te hononga, ka nui te ngaronga o te pēhanga, ka pā ki te roa o te ora o te raina.

5) Mena he wāhi purenga ārai pērā i ngā tāke rokiroki me ngā whakamaroke i muri i te pūwero, ko te whakaritenga paipa pai ko te pūwero + te wehewehe hau-wai + te tāke rokiroki + te tātari-mua + te whakamaroke + te tātari-muri + te tātari pai. Ka taea e tēnei tāke rokiroki te tātari i ētahi o te wai whakapūhau, ā, i te wa ano, he mahi anō tā te tāke rokiroki ki te whakaiti i te pāmahana o te hau kōpeke. Ka taea te whakaiti i te kawenga ki runga i te whakamaroke, te tātari rānei.

6) Mena he nui te hau e whakamahia ana i roto i te pūnaha, ā, he poto te wā, ā, he nui te hau inamata, he mea tika kia tāpirihia he tāke rokiroki hau hei ārai (me nui ake te kaha i te 20% o te kaha hau inamata mōrahi, me rite rānei). Ka taea e tēnei te whakaiti i te maha o ngā kawenga me ngā tangohanga auau o te rōpū kōpeke, te whakaiti i te maha o ngā mahi a te huānga whakahaere, ā, he nui ngā painga mō te pupuri i te pono o te mahi kōpeke. I te nuinga o te wā, ka taea te whiriwhiri i ngā tāke rokiroki hau me te kaha o te 20% o te kaha putanga.

7) Ina kei raro iho te pēhanga o te pūnaha i te 1.5MPa, me raro iho te tere rere i roto i te paipa kawe i te 15m/hēkona hei karo i te hekenga pēhanga nui rawa.
