I roto i ngā pūnaha whakawhiti wai ahumahi, ko ngā rawhi ngongo te wāhanga tino warewarehia. Heoi, he mahi nui tā ēnei here iti ki te ārai i ngā turuturu, ki te pupuri i te pēhanga o te pūnaha, me te whakarite i te mahi haumaru o ngā mīhini katoa. I te whanaketanga o ngā tukanga hangahanga, me te motuhake haere o ngā horopaki tono,ngā rawhi ngongokua whanake mai i ngā taputapu whakakī māmā noa iho ki ngā wāhanga i hangaia kia tino tika me ngā āhuatanga mahi motuhake.
Ka whakaratohia e tēnei tuhinga he tirohanga whānui pūnaha o ngā momo rawhi ngongo matua, ō rātou āhuatanga hangarau, me ngā paearu whiriwhiri e ahu mai ana i te pūtaiao mō ngā tono o te ao tūroa.
1. Ngā Momo Matua me ngā Āhuatanga Hoahoa
I runga i te hoahoa hanganga me ngā mātāpono whakau, ka taka ngā here ngongo kei te mākete ki ngā kāwai matua e whai ake nei:
1.1Ngā Herenga Ngongo Taputapu Kutukutu
Ko ngā rawhi whānui e whakamahia whānuitia ana i roto i ngā wāhi ahumahi. Ko tōna hanganga matua he whitiki (he maitai waro te nuinga, he maitai kore waikura 304/316 rānei), he tīwiri noke, me he whitiki niho.
Ngā Painga:He tino pai te whakawhiti taipana, he pai mō ngā taiao pēhanga teitei; ka taea te whakarite mutunga kore mā te tīwiri noke, e tuku ana i te whānuitanga o ngā mahi.
Ngā Here:I raro i te huringa wera, ka taea e te whānui me te whakaheke o te konganuku te whakaiti i te kawenga, me te hiahia kia hurihia te kaha i ia wā. Ka taea hoki e ngā poka kua tohua ki te whitiki te kino i ngā mata o ngā ngongo silicone, rapa rānei.
Ngā tono noa:Ngā pūnaha whakamatao motuka, ngā paipa ahumahi whānui, te whakamakuku ahuwhenua.
1.2 Puna-Utaina /Ngā Āpiti Taumahatanga Tuturu
He mea hanga ēnei rawhi hei ārai i te turuturu "rerenga matao" i puta mai i te whānui wera, ka whakamahia e rātou te whakarerekētanga pīngore o te maitai puna hei utu mō ngā rerekētanga pēhanga me ngā huringa pāmahana.
Ngā Painga:Whakautu aunoa mō te whakangāwari o te diameter o te ngongo nā te koroheketanga, nā te huringa pāmahana rānei; te pumau o te hiri mō te wā roa.
Ngā Here:He iti te taipana tāutanga tuatahi; kāore i te pai mō ngā pūnaha pēhanga tino teitei.
Ngā tono noa:Ngā raina wahie o te miihini tīhiera, ngā pūnaha whakaputa hau pāmahana teitei, ngā pūnaha whakamatao EGR o ngā taraka taumaha.
1.3 Ngā Here Waea
He mea hanga ēnei mai i te waea maitai puna kua pikohia ki roto i te koropiko, he tino māmā te hanganga. Ka tutuki te hiri mā te kaha whakaheke porowhita.
Ngā Painga:He mama, he iti te utu, ā, e whakarato ana i te pēhanga ōrite 360° me te iti rawa o te kino o te mata ki te ngongo.
Ngā Here:He iti te kaha ki te pupuri i te pēhanga; kāore e tika mō ngā diameter nui.
Ngā tono noa:Ngā ngongo wai o te whare, ngā paipa hau pēhanga iti, ngā taputapu hauora.
1.4Ngā Here Taringa
Ka whakakīia mā te whakapiko i tētahi, i ētahi rānei "taringa" ki te whakamahi i ngā pliers motuhake, ka puta he āhua kirihou tuturu. Kei te wātea i roto i ngā putanga taringa-kotahi me te taringa-rua.
Ngā Painga:Ārai i te whakarerekētanga (kāore e taea te tango me te kore e tapahia); kāore he āputa noke-taputapu, ka hua ake he mata hiri maeneene, kāore he turuturu.
Ngā Here:Kotahi te whakamahinga; me whakamahi taputapu tāutanga motuhake, ka piki ake ngā utu tiaki.
Ngā tono noa:Ngā ngongo kai me ngā ngongo rongoā, ngā pūnaha korehau motuka kounga teitei, ngā raina waipēhi rererangi.
1.5 Taumaha-MahiNgā Āpiti T-Poro
He mea hanga motuhake mō ngā ngongo silicone whānui-rahi e pāngia ana e te wiri nui me te pēhanga teitei. He whānui te whitiki e whakauhia ana e te pūtu-T.
- Ngā Painga: He kaha piri tino kaha, he ātete wiri pai rawa atu; he mea tino pai mō ngā ngongo kowakawaka matotoru-pakipa.
- Ngā Here: He nui rawa, he taumaha, ā, he utu nui.
- Ngā whakamahinga noa: Ngā paipa tomo/putanga turbocharger, ngā pūnaha whakamatao mīhini hanga, ngā tāutanga miihini moana.
2. Ngā Kōwhiringa Pūtaiao Rauemi me te Maimoatanga Mata
Ko te mahi a te rawhi ehara i te mea ko te hoahoa anake engari ko te whiriwhiri rauemi anō hoki. Kua neke te nuinga o te mākete utu nui ki te maitai kore waikura (304/316), engari kei te tuku tonu ngā rāngai utu-iti i ngā kōwhiringa rerekē:
Te maitai waro whakakikoruatia ki te konutea:He ohanga, he pai mō ngā taiao maroke o roto; ko te ātete ki te rehu tote kei raro iho i te 72 hāora te roa.
Paninga piauau wera-toia / paninga Dacromet:Ātete ki te rehu tote mō ngā hāora 240-480; he pai mō ngā taiao o waho me ngā taiao waikura ngawari.
304 kowiri tira:Ātete ki te waikura kai; e whakamahia ana i roto i ngā taiao matū me ngā taiao haukū whānui.
316 kowiri tira:Kei roto ko te molybdenum hei ātete pai ki ngā pūhaumāota me ngā waikawa; kua tohua mō te hangarau moana me ngā pūnaha CIP (Clean‑in‑Place) rongoā.
Ia Au o te Ahumahi: I te whakakaha ake i ngā ture taiao, kua noho ko te whakamahi i te maitai kore-konupora-hexavalent me te maitai kore-kai kounga hei mea whakahau mō ngā kaweake ki ngā mākete o Ūropi me Amerika.
3. Ngā Mahanga Kōwhiringa e Toru, me pēhea te karo i aua Mahanga
I roto i te mahi, he maha ngā wā ka taka ngā miihini ki roto i ngā mahanga e whai ake nei mā te aro nui rawa ki te utu:
Me whakaaro noa ki te diameter o roto, kaua e aro ki te whānuitanga o te whakakī o waho. Ko te rahi kua tohua ki te whakakī e pā ana ki te whānuitanga o ngā diameter o waho o te ngongo e uru ana. Mena he matotoru rawa te pakitara o te ngongo, kāore pea te whakakī e kati katoa ahakoa he ōrite te diameter o roto, ka mutu ka tangohia ngā miro.
E titiro ana ki te whakangāwari o te taipana hihiri. I roto i ngā tono me ngā rerekētanga pāmahana neke atu i te 60°C, me "whakahoki wera" ngā rawhi taputapu kutukutu paerewa i muri i te tāutanga tuatahi. Ki te kore, ka taea e ngā rerekētanga whānui wera te whakaiti i te kawenga o mua o te pūtu me te puta he turuturu.
Te kore e aro ki te ārai i te whakapataritari i ngā miro kowiri tira. Ka ngāwari ngā miro kowiri tira ki te whakarewa makariri (whakapataritari) ina whakakīia i te tere teitei. Ka pania e ngā hua kounga teitei te PTFE, te paninga molybdenum disulphide rānei ki ngā miro. Ki te kore, me whakamahi he matū ārai-hopu i te wā tāutanga.
Whakamutunga
Ahakoa te iti, he mea nui ngā rawhi ngongo mō te haumaru o te pūnaha. Mai i ngā mahi hangarau tawhito o ngā hoahoa taputapu kutukutu ki te pūtaiao rauemi o ngā rawhi kume-pūmau, ā, i nāianei ki ngā putanga hou o te aroturuki mamati, kei te anga whakamua te umanga ki te tika ake, te ātete ki te waikura, me te mohio. Mō ngā kaihanga taputapu, ko te whakarērea o te whakaaro tawhito "he taputapu noa iho ngā rawhi" me te whiriwhiri i runga i te pūtaiao i runga i te pēhanga, te pāmahana, te pāpāho, me te wiri ko ngā huarahi utu iti rawa hei whakapai ake i te pono o te mīhini whānui.
