Ko te pūwhakaoho hau he pūwhakaoho e whakamahi ana i te pēhanga hau hei akiaki i te whakatuwheratanga, te kati, te whakahaere rānei i te takirere. Ka kiia hoki ko te pūwhakaoho hau, he taputapu hau rānei. I ētahi wā ka whakauruhia ngā pūwhakaoho hau ki ētahi taputapu āwhina. Ko ngā mea e whakamahia whānuitia ana ko ngā tūnga takirere me ngā tikanga wira-ringa. Ko te mahi a te tūnga takirere ko te whakamahi i te mātāpono urupare hei whakapai ake i te mahi a te pūwhakaoho kia taea ai e te pūwhakaoho te whakatutuki i te tūnga tika e ai ki te tohu whakahaere o te kaiwhakahaere. Ko te mahi a te tikanga wira-ringa ko te whakamahi hei whakahaere tika i te takirere whakahaere hei pupuri i te whakaputanga noa ina pakaru te pūnaha whakahaere nā te motuhanga hiko, te motuhanga hau, te kore putanga o te kaiwhakahaere, te korenga rānei o te pūwhakaoho.
Te Mātāpono Mahi o te Pūwhakaoho Hau
Ina uru te hau kōpeke ki te pūkaha hau mai i te pūwero A, ka panaia e te hau ngā piston takirua kia neke raina ki ngā pito e rua (ngā pito o te pane rango), ā, ka panaia e te whatanga i runga i te piston te taputapu i runga i te rakau hurihuri kia huri 90 nekehanga ki te taha maui, ā, ka whakatuwheratia te takirere. I tēnei wā, ka tukuna te hau i ngā pito e rua o te pūkaha hau mai i te pūwero B. I te ritenga ke, ina uru te hau kōpeke ki ngā pito e rua o te pūkaha hau mai i te pūwero B, ka panaia e te hau te piston takirua kia neke raina ki waenganui, ā, ka panaia e te whatanga i runga i te piston te taputapu i runga i te rakau hurihuri kia huri 90 nekehanga ki te taha maui, ā, ka kati te takirere. I tēnei wā, ka tukuna te hau i waenganui o te pūkaha hau mai i te pūwero A. Koinei te kaupapa tuku o te momo paerewa. E ai ki ngā hiahia o te kaiwhakamahi, ka taea te tāuta i te pūkaha hau me te kaupapa tuku rerekē ki te momo paerewa, arā, ka huri te tuaka kua tohua ki te taha maui hei whakatuwhera i te takirere, ā, ka huri ki te taha maui hei kati i te takirere. Ko te pūwero A o te pūwero hau mahi-kotahi (momo puna whakahoki) te tomokanga hau, ā, ko te pūwero B te kōhao putanga hau (me tāuta he ārai hau ki te pūwero B). Ka huaki te takirere mā te tomokanga o te pūwero A, ā, ka kati te takirere mā te kaha puna ina tapahia te hau.
Te Mahi a te Pūwhakaoho Hau
1. Me tutuki te kaha whakaputa kua whakatauria, te taipana rānei o te taputapu hau ki ngā ture o te ao me ngā ture a te kiritaki.
2. I raro i ngā āhuatanga kore-kawenga, ka whakauruhia te pēhanga hau ki roto i te rango e tohua ana i te "Ripanga 2", ā, me maeneene te nekehanga, me te kore e piri, e ngokingoki rānei.
3. I raro i te pēhanga hau o te 0.6MPa, ko te taipana putanga, te pana rānei o te taputapu hau i ngā ahunga whakatuwheratanga me te katinga kaua e iti iho i te uara kua tohua ki te pereti ingoa o te taputapu hau, ā, me ngāwari te mahi, ā, kāore he whakarerekētanga tuturu, he āhuatanga rerekē rānei e puta i tētahi wāhanga.
4. Ina whakahaerehia te whakamātautau hiri me te pēhanga mahi mōrahi, kaua te nui o te hau e turuturu ana mai i ia taha pēhanga whakamuri e neke ake i te (3+0.15D)cm3/min (āhua paerewa); kaua te nui o te hau e turuturu ana mai i te taupoki pito me te pou whakaputa e neke ake i te (3+0.15d)cm3/min.
5. Ka whakahaerehia te whakamātautau kaha me te 1.5 ngā wā o te pēhanga mahi mōrahi. Whai muri i te pupuri i te pēhanga whakamātautau mō te 3 meneti, kāore e whakaaetia kia turuturu, kia rerekē rānei te hanganga o te taupoki pito rango me ngā wāhanga hiri tūmau.
6. Ko te maha o te roa o te mahi, ka whakatauira te taputapu hau i te mahi a te takirere hau. I raro i te tikanga o te pupuri i te taipana putanga, i te kaha pana rānei i ngā taha e rua, kaua e iti iho i te 50,000 ngā wā o te whakatuwheratanga me te kati (kotahi te huringa whakatuwheratanga-kati).
7. Mō ngā taputapu hau me ngā tikanga ārai, ina neke te piston ki te tūranga mutunga o te whiu, kāore e whakaaetia te pānga.
Ngā Painga o ngā Pūwhakaoho Hau
1. Ka whakaaetia ngā tohu hau tonu, ka whakaputaina he nekehanga rārangi (whai muri i te tāpiri i tētahi taputapu hurihanga hiko/hau, ka taea hoki e ia te whakaae i ngā tohu hiko tonu). Ka taea e ētahi te whakaputa nekehanga koki i muri i te whakaurunga ki tētahi ringa ruru.
2. He mahi pai, he mahi kino hoki.
3. He tere te neke, engari ka pōturi te tere ina piki ake te kawenga.
4. E pā ana te kaha whakaputa ki te pēhanga whakahaere.
5. He tino pono, engari kāore e taea te pupuri i te takirere i muri i te whakakorenga o te pūtake hau (ka taea te pupuri i muri i te tāpiri i te takirere pupuri-tūnga).
6. He mea whakararuraru te whakatinana i te mana wehewehe me te mana hōtaka.
7. He māmā te tiaki, ā, he pai te urutau ki te taiao.
8. Mana whakaputa nui.
9. He mahi ātete-pahū tōna.
I te raumati
Kua hoahoatia ngā āhuatanga tāutanga me te hononga o ngā whakaterenga hau me ngā takirere kia rite ki ngā paerewa o te ao ISO5211, DIN3337 me VDI/VDE3845, ā, ka taea te whakawhiti ki ngā whakaterenga hau noa.
E rite ana te pū kōhao pūtake hau ki te paerewa NAMUR.
He tapawhā rua te kōhao huihuinga o raro o te pūwhakaoho hau (e rite ana ki te paerewa ISO5211), he mea watea mō te tāutanga raina, 45° rānei o ngā takirere me ngā tokotoko tapawhā.
