Te whakahaere i ngā hiri miihiniI roto i ngā taiao e neke atu ana i te 200°C (392°F) ka puta he wero nui ki te wera me te whakarewa. I roto i ēnei tono pāmahana teitei, ko te whakatau ko tēhea hoahoa hiri e tino whakarato ana i te roa o te ora ratonga me tātari i te manawanui wera o te hiri me ngā hihiri pūnaha e karapoti ana. Ko te hiri e roa ake ana te ora ehara i te mea he wāhanga pakari noa iho; ko te pou here o te mahi tonu, haumaru hoki o te tipu.

Te pānga o te kati, te turuturu, me te tiaki

He nui ngā hua pūtea me ngā hua whakahaere o te pakaru wawe o te hiri i roto i ngā pūnaha pāmahana teitei. Kotahi te pakaru kino o te hiri i roto i tepapu wai weraka hua ake pea he kati tonu i ngā tipu, me te utu wā kore mahi i roto i ngā whare hanga hinu e neke atu ana i te $50,000 ia hāora. Hei tāpiri, he nui ngā mōrearea haumaru me te taiao i te turuturu pāmahana teitei, tae atu ki te mura-ā-unoa o ngā matū waro mimiti (VOC) me te takahi i ngā ture tukunga rerenga pakari, e whakahau ana i ngā reiti turuturu i raro iho i te 500 wāhanga ia miriona (ppm). Ka whakaiti tika te roa o te ora ratonga i ēnei mōrearea pūtea me te taiao kāore e whakaaetia.

Ngā tono e ārahi ana te roa o te hiri i te kōwhiringa

Ko te hiahia kia roa te hiri e tino kitea ana i roto i ngā ahumahi tukatuka tonu. Ko ngā papu wai whāngai kohua, e mahi ana i ngā pāmahana tae atu ki te 250°C (482°F) me ngā pēhanga neke atu i te 150 pae, me whai hiri ka taea te tu atu i ngā huringa tere o te āhua me te kanapa o te wai. Waihoki, ko te wai whakawhiti wera (HTF) e pupuhi ana i ngā hinu hangai e rere ana i te 350°C ki te 400°C (662°F ki te 752°F) e hiahiatia ana.ngā tikanga hiri motuhakee ātete ana ki te whakahekenga wera nui. I roto i ngā papa whakahoro korehau me ngā waeine kōkō whakaroa, i te wā e tunua ai ngā warowaihā taumaha hei totoka whakakoi, ko te kaha o te hiri miihini ki te ora i te wera nui me te kore e aukati ka noho hei kaupapa matua mō te whiriwhiri taputapu.

He aha te mea e whakatau ana i te roa o te hiri mīhini i te pāmahana teitei

Ko te roa o te hiri miihini i raro i te wera nui e whakatauhia ana e tōna kaha ki te pupuri i te kiriata wai pumau, te ātete i te huringa wera nui, me te whakauru i te rerekētanga o te horapa wera o ōna wāhanga o roto. Ina piki te pāmahana, ka heke te matotoru o te wai, ka pana te hiri kia tata atu ki te rohe whakahinuhinu, ka tere ake te pakaru.

Ngā āhuatanga hoahoa hiri

Ko te hoahoa hoahoa o te hiri te mea matua e whakatau ana i te manawanui ki te pāmahana teitei. Ko ngā hiri pana, e whakawhirinaki ana ki ngā mowhiti-O hihiri hei whakatairanga i te mata o te hiri i a ia e mau ana, he tino ngawari ki te "whakairi" ina pakaru ngā elastomers, ina kokiri rānei te wai tukatuka i te taha o te rakau. I tetahi atu taha, ko ngā hiri pere whakarewa kua whakapirihia ki te taha tūmau e kiia ana ko te paerewa ahumahi mō ngā pāmahana neke atu i te 260°C (500°F). Mā te whakakore i te elastomer tuarua hihiri, ka mau tonu te uta mata o ngā hiri pere, ā, ka uru ki te whakawhānui o te rakau me te kore e tūpono ki te whakapūnga waro o te mowhiti-O.

Ngā rauemi mō ngā mata, ngā hiri tuarua, me ngā wāhanga whakarewa

He mea nui te whiriwhiri rauemimō te pumau o te wera. Mō ngā mata hiri, he pai te kawe wera o te karawiti silicon sintered (SiC), ā, ka taea te tu atu i ngā pāmahana taiao tae atu ki te 1,400°C, ahakoa he ngawari ki te ru wera. Ko te karawiti tungsten kua honoa ki te karawiti waro ātete-pupuhi motuhake te mea e pai ake ana mō ngā tono hinu wera-teitei. Mō ngā hiri tuarua, ka eke ngā perfluoroelastomers (FFKM) ki tō rātou rohe wera tino tata ki te 327°C (620°F). I tua atu i tēnei paepae, me whakamahi ngā poro karawiti ngāwari, te takai Grafoil rānei—e kaha ana ki te tu atu ki te 450°C (842°F) i roto i ngā taiao waikura me te neke atu i te 1,000°C i roto i ngā hau kore mahi. Ko te tikanga, me whakamahi ngā koranu nikara-teitei pērā i te Alloy 718, Hastelloy C-276 rānei hei ārai i te ngoki pāmahana-teitei me te pupuri i ngā tere puna tika.

Ngā aratau rahunga noa i raro i te wera

Ka puta te wera i ngā momo rahunga motuhake e whakapoto rawa ana i te roa o te hiri. Ka whakarerekē te whakararuraru wera, pērā i te coning, te camming rānei, i te āputa moroiti i waenga i ngā mata hiri, ka puta he turuturu nui, he rere maroke rānei. Ka puta te coking ina pakaru ngā warowaihā i ngā mata hiri wera, ka puta he putunga waro whakakoi e whakangaro ana i te papatahi o te mata. Hei tāpiri, ko te extrusion elastomer me te tirotiro wera (te pakaru moroiti o ngā mata pakeke nā te huringa wera tere) te take o neke atu i te 40% o ngā rahunga wawe i roto i ngā tukanga e mahi tonu ana i runga ake i te 200°C.

Me pēhea te whakataurite i ngā hiri mīhini pāmahana-teitei

Me arotake e ngā kaihangarau te rohenga tere-pēhanga (PV), e tautuhi ana i te kaha o te hiri ki te whakahaere i te wera waku e puta ana i ngā mata e hono ana. Me tautoko pai ngā hiri pāmahana-teitei i ngā uara PV neke atu i te 50,000 psi-ft/min (17.5 MPa-m/s) me te kore e whiti te kiriata wai. Hei tāpiri, me pupuri tonu te ātete papatahi o te mata i raro i te kawenga wera, me te hiahia kia manatokohia te whatu o ngā roopu rama helium 2 ki te 3 (tata ki te 0.58 ki te 0.87 microns) kia pai ai te tohatoha kawenga me te ārai i te tirotiro wera ā-rohe.

Ripanga whakatairite mō te aromatawai hiri

E whakaatu ana te ripanga e whai ake nei i ngā whirihoranga hiri matua e rua e whakamahia ana i roto i ngā tono pāmahana teitei, e whakaatu ana he aha i roa ai te ora o ētahi hoahoa motuhake i ētahi atu i te wera nui.

Te utu mō te huringa ora me te MTBF

Ahakoa he 150% ki te 200% te utu hoko tuatahi mō te hiri whakarewa taha-whakapiripiri ki te whakaritea ki te hiri pana paerewa, he pai ake te āhua o te huringa ora ki te hoahoa motuhake ki te pāmahana teitei. Ko te Wā Toharite i waenganui i ngā Rahunga (MTBF) te inenga matua mō te roa o te ora. Te whakapai ake i tepapu hinu weraki tētahi hiri pupuhi motuhake ka taea te whakaroa i te MTBF mai i te 8 marama kāore e whakaaetia ki te neke atu i te 48 marama. Ina whakaarohia te mahi, ngā wāhanga whakakapinga, me te karo i te wā kore mahi, ka whakaitihia te utu katoa o te mana whakahaere (TCO) mō te wā e rima tau mā te 40% neke atu rānei.

Me pēhea te whakamātautau me te whiriwhiri i te hiri tika

Ko te whakamana i te hiri ā-ringa mō te taumahatanga pāmahana nui e hiahiatia ana he tikanga whakamātautau tino pakari me te huarahi pakari ki te whakapūmau kounga me te tuhi tuhinga i mua i te taenga o te hiri ki te papa o te wheketere.

Ngā mahi whiriwhiri hei karo i te korenga o mua

Ko te whiriwhiri i te hiri tika me piri pono ki ngā paerewa ahumahi, inā koa ko te API 682 mō ngā rāngai hinu, hau, me te matū hinu. Ko tētahi taahiraa nui hei karo i te pakaru wawe ko te whiriwhiri i te mahere paipa tika. He maha ngā wā, kāore e taea e te hiri te tu atu i ngā pāmahana tukanga tino nui. Mā te whakatinana i tētahi Mahere API 23, e huri ana i te wai mā roto i tētahi whakamatao hiri, i tētahi pūnaha wai ārai Mahere API 53B rānei, ka taea te whakaiti i te pāmahana rūma hiri mai i te 350°C ki raro ki te 150°C ka taea te whakahaere. He rite tonu te hiranga o te aromatawai i ngā whakaritenga whakamahana o te mahere horoi ki te whiriwhiri i te hiri tūturu.

Te kounga hanga me te whai i ngā rauemi

Kāore he wāhi hapa mō ngā ātete hanga mō ngā hiri pāmahana teitei. He mea nui te kounga o te whakarewa i runga i ngā pupuhi whakarewa; me whakamahi ngā kaihanga i te whakarewanga moroiti-plasma tika, me te whakamātautau turuturu i te inenga papatipu helium ki te paepae o te 1 × 10^-8 atm cc/sec kia kore ai e pakaru ngā pupuhi i raro i te huringa wera nui. Hei tāpiri, he mea nui te whai i ngā rauemi, nā te mea ko te hanganga matū tika o te koranu pupuhi te mea e whakatau tika ana i tōna roanga o te ngenge pāmahana teitei me te pupuri i te puna.

Ngā whakaritenga mō te whakatutuki me te tuhi tuhinga

Mā te tuhinga tutuki i ngā whakaritenga ka kitea te kounga e tika ana mō ngā hanganga matua. Me tono ngā miihini i ngā pūrongo whakamātautau rauemi (MTR) EN 10204 Momo 3.1 mō ngā wāhanga whakarewa katoa e pupuri-pēhanga ana me ngā wāhanga whakarewa hihiri. I roto i ngā tono e honoa ana ngā pāmahana teitei ki te hau kawa, ki ngā huānga waikura rānei, me tino tutuki ngā whakaritenga ki te NACE MR0175/ISO 15156 hei ārai i te pakaru o te ahotea whanariki i roto i ngā wāhanga whakarewa o te hiri i ngā pāmahana teitei.

He aratohu kōwhiringa mā te awhe wai me te pāmahana

Ko ngā āhuatanga wai te mea e whakatau ana i te rautaki hiri wera. He tino ngoikore te hinu whakahinuhinu o te wai pāmahana teitei (whāngai kohua), ā, ka mura tonu te mamaoa ina heke te pēhanga, me whai mahere whakamatao pēhanga teitei motuhake. I tetahi atu taha, he pai ake te hinu whakahinuhinu o ngā hinu wera engari he tino ngāwari ki te kōkō me te totoka ina pāngia e te hau.

Anga whakatau mō te kōwhiringa whakamutunga

Me whakakotahi te anga whakatau whakamutunga i te pāmahana, te pēhanga, me te hototahi matū. Me tatau e ngā miihini ngā tauwehenga whānui wera rerekē i waenga i te anga papu, te pou, me te repe hiri. Mena ka whānui haere ēnei wāhanga i ngā tere rerekē i te wā tīmatanga, ka taea te hanga i tētahi āputa whakaputanga kino rawa atu i te 0.15 mm, ka puta ai he pahūtanga hiri tonu ahakoa te whakatauranga pāmahana o roto o te hiri. Mā te whakarite paerewa i runga i ngā pupuhi whakarewa tūmau me ngā hiri tuarua karāhe mō ngā pāmahana neke atu i te 260°C, me te tautoko i a rātou me ngā mahere whakamatao API pakari, ka taea e ngā kaiwhakahaere te whakatutuki pono i te roanga ratonga maha-tau i roto i ngā tono wera tino uaua.
