He taputapu e whakamahia whānuitia ana te pūtu i roto i ngā taputapu whakapiri, he whānuitia te whakamahinga, engari he maha ngā raruraru ka pā mai i te whakamahinga roa, pērā i te ngoikore o te hononga, te kore e ranea o te kaha o te piri, te waikura o te pūtu me ērā atu mea. Ka pāngia te kounga me te whai huatanga o te mahi miihini nā te ngoikore o te hononga o ngā pūtu i te wā e mahi miihinihia ana ngā wāhanga. Nō reira, me pēhea te wetewete i te pūtu?
E toru ngā tikanga ārai-wetekina e whakamahia whānuitia ana: te ārai-wetekina o te waku, te ārai-wetekina ā-ringa me te ārai-wetekina tuturu.
- Pūrua takirua
Te mātāpono o te nati ārai-wetewete i runga: e rua ngā mata waku ina ārai-wetewete ngā nati takirua. Kei waenganui i te nati me te here te mata waku tuatahi, ā, kei waenganui i te nati me te nati te mata waku tuarua. I te wā tāutanga, ko te taumahatanga o mua o te mata waku tuatahi he 80% o te mata waku tuarua. I raro i ngā kawenga pānga me te wiri, ka heke te waku o te mata waku tuatahi, ka ngaro, engari i te wā kotahi, ka pēhia te nati tuatahi, ka piki ake te waku o te mata waku tuarua. Me wikitoria ngā waku tuatahi me te tuarua ina wetewetehia te nati, nā te mea ka piki ake te kaha waku tuarua i te hekenga o te kaha waku tuatahi. Mā tēnei, ka pai ake te pānga ārai-wetewete.
Te mātāpono ārai-wetekina o te miro whakararo: Ka whakamahia hoki e ngā here miro whakararo ngā nati takirua hei ārai i te wetekina, engari ka huri ngā nati e rua ki ngā taha rerekē. I raro i ngā kawenga pānga me te wiri, ka heke te waku o te mata waku tuatahi, ka ngaro.
- Hangarau ārai-wetewete miro poro 30°
He koki porowhita 30° kei te pūtake o te niho o te miro uwha porowhita 30°. Ina whakaukia ngā nati pūtu, ka pēhia kaha ngā pito niho o te pūtu ki te koki porowhita o te miro uwha, ka hua ake he kaha raka nui.
Nā te panonitanga o te koki o te āhua, ko te kaha noa e pā ana ki te pa o ngā miro kei te koki 60° ki te kakau pūtu, kaua ki te 30° pērā i ngā miro noa. He mārama ko te pēhanga noa o te miro poro 30° he nui ake i te pēhanga kume, nō reira me whakanui rawa te waku ārai-wetewete e puta mai ana.
- Mai i te nati raka
Kua wehea kia rua: ngā nati raka-ake kaha-teitei e whakamahia ana mō ngā mīhini hanga rori, ngā mīhini keri, ngā taputapu miihini, ngā nati wiri-ake-ake kaha-nui, e whakamahia ana i roto i te rererangi, i ngā waka rererangi, i ngā tāke, i ngā mīhini keri, pērā i ngā nati raka-ake-ake nairona, ā, e whakamahia ana kia kaua e neke ake i te 2 ATM te pēhanga mahi mō te penehīni, te hinu kakara, te wai, te hau rānei hei reo mahi e whakamahia ana mō te – 50 ~ 100 ℃ pāmahana takai nati raka-ake-ake i runga i te hua, me te nati raka-ake puna.
- Kāpia maukati miro
Ko te kāpia maukati miro he (methyl) te ester kiriaku, te kaiwhakaoho, te kaiwhakatairanga, te whakau (te aukati i te polymer), te tae me te whakakī i roto i tētahi ōwehenga o te kāpia.
Mō te āhua puta noa i te kōhao: tukuna te pūtu mā roto i te kōhao tīwiri, tāpirihia te kāpia maukati miro ki te miro o te wāhanga mata, huihuia te nati ka whakaū ki te taipana kua tohua.
Mō te āhua e nui ake ai te hōhonutanga o te kōhao tīwiri i te roa o te pūtu, me tāpiri te kāpia maukati ki te miro pūtu, me huihui, ā, me whakau ki te taipana kua tohua.
Mō te āhua o te kōhao matapo: maturuturu te kāpia raka ki raro i te kōhao matapo, kātahi ka tāpirihia te kāpia raka ki te miro o te pūtu, huihuia, ka whakau ki te taipana kua tohua; ki te whakatuwheratia te kōhao matapo ki raro, ko te kāpia raka anake ka tāpirihia ki te miro o te pūtu, ā, kāore he kāpia e hiahiatia ana ki te kōhao matapo.
Mō te āhua mahi o te pūtu takirua-upoko: me maturuturu te kāpia raka ki roto i te kōhao tīwiri, kātahi ka pania te kāpia raka ki runga i te pūtu, kātahi ka huihuia te pou me te whakakaha ki te taipana kua tohua; i muri i te huihuinga o ētahi atu wāhanga, tāpirihia te kāpia raka ki te wāhanga whatunga o te pou me te nati, huihuia te nati me te whakakaha ki te taipana kua tohua; ki te tuwhera te kōhao matapo ki raro, kāore he maturuturunga kāpia ki roto i te kōhao.
Mō ngā here miro kua oti kē te huihui (pērā i ngā tīwiri whakarerekē): i muri i te huihuinga me te whakau ki te taipana kua tohua, maturuturu te kāpia maukati ki te wāhi honohono o te miro kia taea ai e te kāpia te uru noa.
- Mōkihi takai takirua ārai-whakauru maukati
Kua āraia te niho kani radial i te mata o waho o te mīhini horoi raka kua werohia e te mata o te mea mahi e pā ana ki a ia. Ina pā te pūnaha ārai-whakangā ki te kawenga hihiri, ka taea anake te nekeneke i te mata o roto o te gasket.
Ko te tawhiti toronga o te horoi raka poro i te ahunga o te matotoru toronga he nui ake i te nekehanga roa o te miro toronga o te pūtu.
- Pine wehea me te nati kōhao
Kia whakaukia te nati, whakauruhia te pine cotter ki roto i te mokowā nati me te kōhao hiku o te pūtu, ka whakatuwhera i te hiku o te pine cotter hei ārai i te hurihanga ōrite o te nati me te pūtu.
- Waea maitai raupapa wetekina
Ko te ārai i te wetewete o te waea maitai raupapa ko te whakauru i te waea maitai ki roto i te kōhao o te pane o te pūtu, ka hono i ngā pūtu kia mau tetahi ki tetahi. He huarahi tino pono tēnei ki te whakangāwari, engari he uaua ki te wetewete.
- Whakamutu i te gasket
Kia whakaukia te nati, pikohia te horoi aukati kotahi-pū, takirua-pū rānei ki te taha o te nati me te hononga hei raka i te nati. Mēnā me hono rua ngā pūtu e rua, ka taea te whakamahi i ngā horoi aukati takirua hei hanga i ngā nati e rua kia pakaru tetahi ki tetahi.
- Horoi puna
Ko te mātāpono ārai-wetewete o te horoi puna, i muri i te whakawhāititanga o te horoi puna, ka puta he ngāwari tonu i te horoi puna, kia mau tonu ai te kaha waku o te hononga miro nati me te pūtu, kia puta ai he ātete ātete, kia kore ai e wetewete te nati.
- Hangarau whakapiri wera rewa
Ko te hangarau whakamau rewa wera, me te kore e hiahiatia he whakatuwheratanga i mua, ka taea te pato tika i roto i te kōtaha kati hei whakatutuki i te hononga, he maha te whakamahinga i roto i te umanga motuka.
Ko tēnei hangarau whakamau rewa wera he tukanga hanga matao o te whakapiri-ā-ringa me te hononga tīwiri i muri i te hurihanga tere-teitei o te motuka ki te rauemi rau hei hono mā te whakakī i te kakau i waenganui o te taputapu, ā, ka puta te whakarerekētanga kirihou i te wera waku.
- kua utaina i mua
Ko te hononga pūtu kaha teitei, kāore e hiahiatia he mahi ārai-wetewete tāpiri, nā te mea ko ngā pūtu kaha teitei e hiahia ana ki te kaha whakakī-mua nui, ā, mā te kaha whakakī-mua nui i waenganui i te nati me te hononga ka puta he pēhanga kaha, ka ārai tēnei pēhanga i te hurihanga o te taipana waku o te nati, kia kore ai e wetewete te nati.
