Te hoahoa o ngā hononga paipa me ngā rawhi ngongo:

Ko te otinga whakapūmau whai hua e whakawhirinaki ana ki ngā whakapūmau ngongo me ngā hononga. Mō te mahi hiri tino pai, me whai whakaaro ki ngā āhuatanga e whai ake nei i mua i te tāutanga o te whakapūmau:

1. Ko ngā hononga momo-tō te mea pai rawa atu mō te hiri, engari kāore e pai mō ngā pakitara angiangi, ngā tono pēhanga iti rānei.

2. Me rite te rahi o te hononga paipa kia paku totoro te ngongo i runga i te hononga paipa. Ki te whiriwhiri koe i tētahi hononga nui rawa, ka uaua ki te whakau katoa, engari ki te iti rawa te rahi, ka ngāwari te wetewete, te kōpiri rānei i te ngongo kia kotahi.

3. Ahakoa pēhea, me kaha te hononga paipa ki te tu atu i te kaha pēhi o te rawhi, ā, ka tīpakohia ngā rawhi taumaha ina he rauemi pakari, he rauemi ngāwari hoki te ngongo me te paipa. Pana: Te Pānga o te Diameter ki te Pana Tuaka: Ko te pikinga o te pēhanga i roto i te ngongo ka hanga he pana tuaka e pana ana i te ngongo kia puta atu i te pito nipple.

Nō reira, ko tētahi o ngā whakamahinga matua o ngā rawhi ngongo ko te ātete i te pana axial hei pupuri i te ngongo kia mau tonu. Ka inehia te taumata pana axial mā te pēhanga i puta i roto i te ngongo me te tapawhā o te diameter o te ngongo.

Hei tauira: ko te pana axial o te ngongo he diameter o roto 200mm he kotahi rau ngā wā i te ngongo he diameter o roto 20mm. Nō reira, ka tino taunaki mātou i ngā rawhi ngongo mahi taumaha mō ngā ngongo diameter nui me te pēhanga teitei. Ki te kore, kāore tō ngongo e roa. Te whakapūmau tika Me whakapūmau tetahi rawhi ki te whakapūmau tika kia tika ai te mahi. Mō ngā rawhi taraiwa kutukutu kua whakapūmauhia, ka whakaratohia e mātou ngā uara taipana mōrahi. Kāore e kore, mō tētahi pupuri, ko te nui ake o te taipana whakauru, ko te nui ake o te kaha rawhi. Heoi, kāore e taea te whakamahi i tēnei tau hei whakataurite i te kaha whanaunga o ngā rawhi; nā te mea ka whai wāhi mai hoki ētahi atu āhuatanga pēnei i te whānui o te miro me te whitiki. Mena kei te whakaaro tonu koe ki ngā kōwhiringa mō ngā rawhi me ngā topenga rerekē, ka tino taunaki mātou kia arotakehia e koe ngā pukapuka i runga i tā mātou paetukutuku kia tino whakarite kei te tutuki koe i ngā taumata whakapūmau kua tūtohutia mō ā mātou awhe katoa. Te rawhi ngongo kua whakanohoia tika Ina whakapūmau i te rawhi ngongo, ka pēhia te ngongo ka puta he pēhanga. Ka rerekē te āhua o te ngongo i te hua o te tauhohenga mekameka, nō reira kaua e whakanoho te rawhi ki te pito o te ngongo, kei te tūpono ka turuturu, ka marere rānei ina whakanohoia te rawhi ki raro i te pēhanga. Ka tūtohu mātou kia 4mm te iti rawa o ngā rawhi mai i te pito o te ngongo,

 

He rerekē ngā diameter o ngā rawhi ngongo katoa, nō reira he mea nui kia tika te rahi. Ahakoa ka whiriwhiria e koe tētahi, ka kitea e koe he whānuitanga kei roto. Anei me pēhea te whakarite kia tika te diameter o te rawhi ngongo. Tuatahi: Whai muri i te whakatōnga o te ngongo ki te hononga, inehia te diameter o waho o te ngongo. I tēnei wā, tata tonu ka whānui te ngongo, ā, ka nui ake i tōna āhua i mua i te whakaurunga ki te paipa. Tuarua, whai muri i te ine i te diameter o waho, tirohia te whānuitanga hihiri o te rawhi ngongo kia tino taea ai te whakakī ki te rahi tika. Kei te wātea katoa ā mātou rawhi i roto i te diameter iti me te diameter mōrahi, ko te mea pai me whiriwhiri e koe ngā rawhi e uru ana ki te OD o tō ngongo e kapi ana i waenganui o tēnei whānuitanga. Mena kei te whiriwhiri koe i waenga i ngā rahi e rua, whiriwhiria te rawhi iti ake nā te mea ka pēhia te ngongo ina tū ki tōna tūranga. Mena kāore e taea te whiriwhiri i te whānuitanga waenga, he whaiti rānei te whānuitanga hihiri o te rawhi ngongo e whakaarohia ana e koe, ka tūtohu mātou kia tono koe i tētahi tauira o te rahi tata (ka taea e koe te tono i tētahi rawhi i runga i tā mātou paetukutuku) kātahi ka tono katoa Whakamātauria i mua i te rahinga.
