A pūmau ngongoHe taputapu miihini e whakamahia ana hei whakapiri me te hiri i te ngongo ki runga i tētahi hononga pēnei i te tara, i te nipple rānei. Ko tana mahi matua he ārai i te turuturu o te wai, te hau rānei i te pūwāhi hononga. Ahakoa he māmā noa te ariā, ko te whiriwhiri i te rawhi ngongo he pānga nui ki te pono me te roa o te mahi o tētahi pūnaha paipa, pūnaha kawe rānei.
E whakaahua ana tēnei tuhinga i ngā momo rawhi ngongo noa, ngā rauemi noa, me ngā āhuatanga matua hei whakaaroaro māu i te wā e whiriwhiri ana i tētahi rawhi mō tētahi tono.
Ngā Momo Noa o ngā Herenga Ngongo
Ka aro atu ngā hoahoa rerekē ki ngā taumata pēhanga rerekē, ngā awhe pāmahana, me ngā whakaritenga huihuinga. Kei raro nei ngā momo e whā e whakamahia whānuitia ana.
1. Rawhi Puku Noke
Terawhi puku nokehe whitiki maitai kore waikura me ngā mokowā, he whare, me te tikanga tīwiri. Mā te huri i te tīwiri ka whakau te whitiki huri noa i te ngongo. He pai ēnei rawhi mō ngā tono whānui tae atu ki ngā pūnaha whakamatao motuka, ngā raina hau ahumahi, me ngā ngongo wai pēhanga iti.
Ko te taipana noa kei waenga i te 2 ki te 6 N·m i runga i te whānui me te diameter o te awhi. Heoi, ka taea e ngā rawhi taraiwa noke te hanga i tētahi tohatoha pēhanga kore taurite nā te āputa i roto i ngā mokowā awhi. Nā tēnei take, kāore i te tūtohutia mō ngā ngongo silicone ngohengohe, ngā pūnaha waipēhi pēhanga tino teitei rānei.
2. Pūmau Puna
Ngā rawhi punahe mea hanga mai i te maitai puna, ā, ka mau tonu te kaha radial. Ka whakarerekē aunoa ēnei ki ngā huringa diameter o te ngongo e puta mai ana i ngā piki me ngā heke o te pāmahana, i te ngoki rānei o ngā rauemi. He mea noa ēnei here i roto i ngā pūnaha whakamatao motuka e puta pinepine ai te huringa wera. Kāore e hiahiatia he whakakī anō i ia wā mō ngā here puna, engari he iti ake te kaha here mōrahi e tukuna ana e rātou ki te whakataurite ki ngā here puku kutukutu, ki ngā here T-bolt rānei.
3. Rawhi T-Poro
Ka whakamahia e ngā rawhi poro-T he whitiki kaha-teitei, he tikanga poro-T, me te nuinga o te wā he raina i roto i te whitiki. Ka tukuna e rātou he pēhanga ōrite huri noa i te porowhita katoa, kia pai ai mō ngā tono taumaha pēnei i ngā awa turbocharger, ngā hononga ngongo silicone, me ngā ngongo ahumahi nui te diameter. Ko ngā rawhi poro-T te tikanga ka taea te whakahaere i ngā pēhanga mahi i runga ake i te 10 pae, ā, e wātea ana mō ngā diameter mai i te 50 mm ki te neke atu i te 500 mm.
4. Rawhi Waea
Ko ngā rawhi waea he waea puna roa tonu kua hangaia hei koropiko. Mā te tīwiri, mā te raka rānei e whakatika te whānui o te koropiko. He iti noa te horahanga pā o ēnei rawhi, ā, ka whakaiti i te tūponotanga o te pakaru o ngā ngongo. He maha ngā wā ka whakamahia i roto i ngā raina wahie pēhanga iti, ngā pūnaha korehau, me ētahi mahi ahuwhenua.
Kōwhiringa Rauemi
Me ātete te rauemi o te rawhi ngongo ki te waikura, ki te pāmahana whakahaere, ā, me hototahi ki te wai, ki te hau rānei e haria ana.
Kowiri tira (ngā tohu 304 me te 316): He pai te tohu 304 mō ngā taiao o roto, mō ngā taiao waikura pakupaku rānei. Kei roto i te tohu 316 te molybdenum, e whakapai ake ana i te ātete ki ngā hauota me ngā āhuatanga waikawa. Ko ngā tono tukatuka moana me ngā matū e tohu ana i te tohu 316.
Rino waro whakakikoruatia ki te konutea: He ātete waikura ngawari, he iti ake te utu. He pai mō ngā taiao maroke, mō roto rānei. Kāore i te tūtohutia mō ngā mahi o waho, mō ngā mahi haumākū nui rānei.
Rino piauau: He pai ake te ātete ki te waikura i te rino whakakikoruatia ki te konutea, engari he iti ake te pakari i te rino kore waikura i ngā āhuatanga mākū.
Ngā rawhi pania-polymer, ngā rawhi kirihou katoa rānei: Whakamahia mō ngā mahi e hiahia ana ki te whakamahana hiko, ki te karo rānei i te pa ki te konganuku, pērā i ētahi pūnaha taiwhanga, pūnaha whakahaere kai rānei.
Ngā Paearu Kōwhiri Matua
Me arotake i ētahi tawhā tono i te whiriwhiri i tētahi rawhi ngongo. Me tuhi ngā āhuatanga e whai ake nei i mua i te whakatau.
Rauemi me te pakeke o ngā ngongo: Ko ngā ngongo ngohengohe (hei tauira, te silicone, te rapa iti-durometer) me whai whitiki whānui, me whai arai rānei hei ārai i te tapahi. Ka taea e ngā ngongo mārō, ngā ngongo whakapakari rānei te tu atu ki ngā whitiki whaiti me ngā kaha kume teitei ake.
Pēhanga whakahaere me te pāmahana: Ko te pēhanga teitei ake me whānui ake te whānuitanga o te whitiki me te momo rawhi e tohatoha ōrite ana i te kaha. Ka pāngia te ngongo me te rauemi rawhi e ngā pāmahana tino teitei. Mō ngā pāmahana neke atu i te 150°C, he pai ake te kowiri tira i te kowiri tira waro pania.
Hototahi ki ngā wai: Me whakamahi ngā rauemi ātete ki te waikura mō ngā wai, ngā hau rānei. Mō ngā pūnaha wai inu, me whakamahi pea ngā kōpiri e tutuki ana i ngā paerewa NSF/ANSI 61.
Te urunga ki te tāutanga: I ngā wāhi kuiti, he māmā ake te whakakī i te rawhi me te tīwiri pane ono, te pūnaha taraiwa kōhao rānei, i te tīwiri kōhao noa.
Te wiri me ngā kawenga hihiri: Ka ātete ngā rawhi puna, ngā rawhi T-bolt rānei me ngā taputapu raka ki te wetekina i raro i te wiri. Me whakamahi ngā rawhi puku noke me ngā matū raka-miro, ngā nati raka-ake rānei mēnā he wiri.
Ngā Aratohu Tāutanga
Ka pā tika te tāutanga tika ki te mahi a te rawhi. Ko ngā tikanga e whai ake nei e whakaaetia whānuitia ana.
Whakaturia te rawhi ki runga i te koikoi, i te pakihiwi taumau rānei, kaua ki muri.
Whakakīia te rawhi ki te taipana kua tohua e te kaihanga. Mēnā ka iti te whakakī, ka turuturu; mēnā ka nui rawa te whakakī, ka tapahia pea te ngongo, ka whakapōturitia rānei te hononga.
Mō ngā rawhi puku noke, whakatūria te whare kia matara atu i ngā ara rere tika o te wai ki te taea.
Whakahoutia te taipana i muri i te huringa wera tuatahi, i roto rānei i ngā haora 24 tuatahi o te whakamahinga ina whakamahia ana ngā ngongo rapa.
Ngā Aratau Rahunga Noa
Mā te mārama ki ngā aratau rahunga ka āwhina i te whiriwhiri i te rawhi tika me te pupuri i te tika o te pūnaha.
Te ngaronga o te taipana: Nā te wiri, te huringa wera, te rere makariri rānei o te rauemi ngongo i puta. Me tirotirohia i ia wā, me whakakī anō pea.
Waikura: Ngā hua o te whiriwhiri i tētahi rauemi kāore e tika ana mō te taiao. Ka taea e te waikura o te poka, o te kapiti rānei i raro i te whitiki te arahi ki te pakaru ohorere.
Te tapahi i te ngongo: Ka puta ina keri te taha o te whitiki, te mokowā rānei ki roto i te ngongo ngohengohe. Mā te whakamahi i ngā rawhi kua whakarārangihia, te whakanui rānei i te whānui o te whitiki ka whakaiti i tēnei mōrearea.
Te tangohanga o te tīwiri: Ko te tikanga ka puta mai i te whakakukū rawa, i te whakamahinga rānei o te tīwiri kāore e ōrite ki te momo puku.
Whakamutunga
He māmā noa iho ngā rawhi ngongo engari he mea nui ki ngā pūnaha whakahaere wai me te hau. He rerekē ngā āhuatanga o ia rawhi puku noke, puna, poro-T, me ngā rawhi waea e tika ana mō ngā awhe pēhanga motuhake, ngā rauemi ngongo, me ngā āhuatanga taiao. Me ōrite te kōwhiringa rauemi ki te waikura o te taiao ratonga. Mā te tāutanga tika me te tirotiro ā-wā ka whakaitihia te mōrearea o te turuturu, te rahunga hononga rānei.
Mō ngā kaihanga taputapu taketake me ngā miihini tiaki, mā te tuhi i ēnei tawhā me te whiriwhiri i runga i tēnā ka pai ake te pono o te pūnaha me te kore e nui rawa te whakaritenga, e kore hoki e puta he utu koretake.
