I roto i ngā tukatuka matū tino uaua—pērā i ngā koropiko paru whakakorikori, ngā waeine whakaroa, me ngā tauhohenga polyethylene kiato-teitei (HDPE)—he tino raruraru ngā nohoanga ngohengohe polymeric, elastomeric rānei. Ka tere te hinga o ngā whakaurunga paerewa pērā i te PTFE, RPTFE, tae atu ki te PEEK kua whakapakaritia ki ngā kaha whakangaro o ngā paitini whakakorikori koi, te horo miihini, me te huringa wera nui. Ina pakaru ngā huānga ngohengohe, ka puta tonu te hua: te turuturu o te tākai, te karo i te raina, me te kati ohorere o te tipu.
Hei whakapūmau i te wā mahi miihini me te motuhaketanga tino pai i roto i ngā taiao kino, kei te neke atu ngā tohunga aunoatanga tukanga me ngā miihini pono i ngā takirere taonga whānui. Kei roto i te otinga he taputapu hangarau tino paingā takirere pōro noho whakarewa.
At KAMUPENE RĀWAI O NSW (nswvalve.com), ka hangaia e mātou he pehanga teitei, he ratonga kinongā takirere pōro noho whakarewai hangaia hei whakakore i ngā momo rahunga noa o te horo me te here wera, me te whakarato i te aukati ā-rua, piri tonu.
1. Te Hangarau Whakarewa Pūoro Nui: Ngā Tikanga Paninga HVOF mō ngā Takirere Pōro Nohoanga Whakarewa
Ko te pono o te ratonga matuangā takirere pōro noho whakarewaka whakatauhia e te pumau o te hononga me te pakeke o te mata o ōna paninga mata. Engari i te whakawhirinaki ki te whakakikorua hiko tuku iho,KAMUPENE RĀWAI O NSWngā taputapuTe Wahie Hāora Tere-Teitei (HVOF)te rehu wera. Ka whakamahia e tēnei tikanga ngā matihiko waro matatau ki ngā papa whakarewa-teitei, tae atu ki te ASTM A351 CF8M, CF3M, me ngā maitai kore waikura Super Duplex.
I roto i tā mātou tukanga HVOF motuhake, ka whakaurua te matū mata-mārō ki roto i te awa tahunga e whakakahangia ana e te hāora me te hinu kakara kounga teitei. Ka tere ake ngā matūriki ki ngā tere supersonic e neke atu ana i teMach 3, e huri ana i te kaha nekeneke nui ki roto i tētahi paparanga honohono matotoru, tino iti ($< 0.5\%$). Ko te kaha here ā-pūkaha hua ake he neke atu i te $10,000 \text{ psi}$ ($69 \text{ MPa}$), e whakarite ana kia mārō te paninga o tā tātoungā takirere pōro noho whakarewae kore e motumotu i raro i te kutikuti waiora kaha.

Kōwhiringa Paninga Motuhake mō te Taupānga:
- Kāpiro Tungsten (WC-Co-Cr): He mea hanga motuhake mō te pakaru matūriki taumaha i roto i ā mātoungā takirere pōro noho whakarewaKa whakaratohia e te matihiko he mārō-iti tae atu ki72 HRC, e mahi ana hei pukupuku ātete ki te mahi horoi o ngā matariki whakakorikori me ngā totoka silica.
- Kāpira Konukōmiuma ($Cr_3C_2\text{-NiCr}$)I hangaia mō ngā rauemi whakahāngai pāmahana-tiketike. Ka mau tonu tōna pumau hanganga tioata tae atu ki te $1500^\circ\text{F}$, ka ārai i te pakaru-iti wera me te tauine e whakaiti ana i te ahumahi.ngā takirere pōro noho whakarewai te wā o ngā ru wera tere.
2. Te Whakakore i te Rerenga Papamuri mā te Mate-Lapping Mechanics
Ko tētahi whakaaro hē e kitea pinepine ana i waenga i ngā kaihoahoa paipa ko tengā takirere pōro noho whakarewame whakaiti te pūmautanga o te hiri.KAMUPENE RĀWAI O NSWka whakakorea te arai nohoanga papamuri mā te waeine kotahi motuhakeKawa Whakapā-Hoa.
Engari mō te whakapiri i ngā wāhanga ki ngā pokepoke matua paerewa, ka honoa ia pōro takitahi ki tōna mowhiti nohoanga whakarewa motuhake. Ka whakamahia e ngā tohunga hangarau he tukanga miihini maha-wāhanga me te pāpāho whakakoi taimana pai haere, ka mutu ki tewhakapiri kirikiri 1-micron.
Mā tēnei taurite tika ka tutuki he awhi whakapā $360^\circ$ tonu, he tino pai. Ko te ōritetanga āhuahanga hua ka rite ki ngā paerewa ine ine i te awhi mārama, ka taea ai e NSWngā takirere pōro noho whakarewakia tutuki i ngā wā katoaISO 5208 Reiti A me te API 598 kore-tātarite mahi i raro i te whakamātautau hau pēhanga teitei—e kawe mai ana i te mahi piri-mirumiru ki te hoahoa kati whakarewa taumaha.
3. Te Whakahaere i ngā Totoka Hihiri: Ngā Nohoanga Waro me te Whakatutukitanga Wera
I roto i ngā tono paru taumaha, i ngā tono polymer rānei, ka taea e ngā matūriki kua mau ki te piri i waenga i te pōro me te nohoanga i te wā e huri ana i te hauwhā-huringa, ka puta he tohu hōhonu, he hopu mīhini rānei. Ka whakatauhia e NSW tēnei ngoikoretanga mā te whakamahi i tētahi pūnaha kua arotauhia.Kōtaha Nohoanga Warui honoa ki te uta-mua ā-mīhini hihiri.

Ko te ngutu hiri matua o tā mātou mowhiti nohoanga whakarewa he mata āhuahanga koi, he mea mīhini. I te nekenga o te pōro ki te tūranga kati, ka mahi tēnei kōtaha hei waru miihini, ka kutikuti i te unahi, ngā putunga tioata, me te hanga pūmua piri i mua i te urunga atu ki te mata hiri o tā mātou.ngā takirere pōro noho whakarewa.
Te Whakakorenga Whakawhanui Wera
Ka puta te mōrearea o te herenga wera i ngā tukanga matū pāmahana teitei. Ina piki ake te pāmahana o te pāpāho tukatuka, ka nui ake te tere o te horapa o te pōro i te tinana o te takirere, ka maukati te takirere ki tōna tūranga.
Ka karohia e NSW tēnei take mā te tāuta i ngā mea taumaha, ātete ki te waikura.Ngā puna ngaru Inconel 718 Bellevillekei muri i te huihuinga nohoanga. Ka mau tonu tēnei whirihoranga i tētahi hiri pēhanga iti haumaru, me te whakarato hoki i te ngāwari ā-mīhini e hiahiatia ana hei mimiti i te whānui wera.
4. Te Whakatutukitanga Taiao: Te Tākai Iti-E me te Haumaru Ahi
Ko ngā ture taiao puta noa i Amerika Te Raki e kī ana kia kaua e aro ki ngā tukunga rerenga. Ko ngā kakau takirere te pūtake tino noa o ngā takahi i te EPA LDAR (Te Kite me te Whakatikatika turuturu).
Te Ārai i ngā Tukunga RerengaNSWngā takirere pōro noho whakarewawhakauruhia he huihuinga tākai kakau utaina ora kua whakamanahia kiAPI 641mō ngā takirere huri-hauwhā, mā te whakamahi iAPI 622ngā huinga tākai karāhe ngāwari kua hangaia kia mate. Ka mau tonu te kawenga pēhanga mā roto i ngā horoi puna Belleville, kia mau tonu ai te turuturu o te kakau100 ppmvi roto i ngā huringa wera roa.
Te Haumaru Ahi TūturuKua tino whaimana kiAPI 607 me te API 6FAngā paearu. Nā te mea he mea hanga noa te rohe pēhanga, ngā huānga kati, me ngā hiri kakau ki te konganuku pakari me te karapiti matotoru, ka mau tonu te wehenga hanganga katoa o te takirere i te wā e pāngia ana e te ahi warowaihā ($1400^\circ\text{F}$ ki te $1800^\circ\text{F}$).
