Aratohu Nohoanga Takirere Pōro: Ngā Mahi, Ngā Rauemi (Nohoanga PTFE me Ētahi Atu) me ngā Awhe Pāmahana | Hiri Tino Pai
I te ao ongā takirere pōro, he mea tino nui te hiri whai hua. Kei te ngākau o tēnei mahi nui tētahi wāhanga matua: teNohoanga Takirere Pōro, e kiia noa ana ko teNohoanga TakirereKo tēnei toa ngaro te "toa hiri" tūturu o te huihuinga Ball Valve.
He aha rawa te nohoanga takirere pōro?
TeNohoanga Takirere Pōrokoia te huānga hiri nui i roto i tetakirere pōrohanganga. He mea hanga mai i ngā rauemi whakarewa, kore-whakarewa rānei, ā, ka tāutahia ki roto i te tinana takirere. Ko tana mahi matua he hanga i tētahi hononga hiri piripono me te pōro hurihuri. Mā te pupuri i tēnei hononga piripono, kaNohoanga Takirereka taea e te takirere te whakaweto, te whakahaere rānei i te rere o te wai.
Te Riri Toru o te Nohoanga Takirua: Nui Atu i te Hiri Noa
HouNgā Nohoanga Takirere Pōrohe kaha whakamiharo kei tua atu i te hiri taketake:
1. Hiritanga Urutau (Te Āhua-Ngāwari):Pērā i te urunga pahuka mahara e rite ana ki tō mahunga, ka mau tonu te ngāwari o te Nohoanga Takirua kounga teitei puta noa i ngā awhe pāmahana tino nui (e pā ana ki ngā paerewa ASTM D1710, ko te tikanga -196°C ki te +260°C). Mā tēnei ngāwari ka taea e ia te whakakapi aunoa i ngā pakaru iti i runga i te mata o te pōro, kia mau ai te pumau o te hiri mō te wā roa.
2. Kaiwhakahaere Wai (Te Kaiārai):Ko ngā hoahoa i hangaia mō te hanga motuhake, pērā i ngā Nohoanga Takirere Pōro V-port, ka ārahi i te rere o te wai. Ka āwhina tēnei rere i te horoi i ngā mata hiri, ka ārai i te kohikohinga o ngā paru, o ngā matūriki rānei ka kino pea te hiri.
3. Kaiwhakautu Āwhati (Te Haumaru Ahi):Kei roto i ētahi hoahoa Nohoanga Takirere ngā āhuatanga haumaru-ahi. Mēnā ka tino wera (pēnei i te ahi), ka hangaia ēnei nohoanga kia mura, kia warohia rānei. Kātahi ka hangaia e tēnei paparanga warohia he hiri tuarua, ohorere, mai i te konganuku ki te konganuku, hei ārai i te pakaru kino.
Te Pūtaiao o te Hiri: Te Mahi a te Nohoanga Takirere
Ka puta te hiri mā te pēhitanga ā-tinana tika. Ina huri te pōro ki te tūranga kati, ka pēhi kaha ki teNohoanga Takirere Pōro. Ka whakapōturitia te āhua o te nohoanga e tēnei pēhanga, ka hangaia he ārai ārai-tauraki ki te reo. E rua ngā Nohonga Takirua e whakamahia ana e ngā takirere pōro paerewa – tētahi kei te taha tomo me tētahi kei te taha putanga. I te āhua kati, ka "awhi" pai ēnei nohoanga i te pōro, ka taea te tu atu i ngā pēhanga tae atu ki te 16MPa (mō iaNgā paerewa API 6DKa taea e ngā hoahoa whakarei ake, pērā i ngā nohoanga V-port, te whakapai ake i te hiri mā roto i ngā kaha kutikuti whakahaeretia e pā ana ki te pāpāho.
Ngā Awhe Pāmahana o te Nohoanga o te Takirere Pōro: He Mea Nui ngā Rauemi
Ngā rohe pāmahana mahi o tētahiNohoanga Takirere Pōroe whakatauhia ana e te hanganga o ngā rauemi. Anei te wehewehenga o ngā rauemi nohoanga noa me ō rātou awhe pāmahana matua:
Ngā Nohoanga Takirere Pōro Hiri Ngāwari (He mea hanga ki te Polymer me te Elastomer):
•Nohoanga PTFE (Polytetrafluoroethylene):Ko te kōwhiringa matarohia. He tino pai ngā nohoanga PTFE ki te ātete ki te waikura, ā, he pono te mahi i waenga i-25°C ki te +150°CMō ngā tono uaua e hiahia ana kia huri pinepine, PTFE kua mīhinihia kia tikaKa taea e ngā nohoanga (e tutuki ana ngā ātete ±0.01mm) me ngā pōro kua oti te hanga motuhake te tuku i ngā huringa neke atu i te 100,000 me te kore turuturu – e tutuki ana i te paerewa hiri ISO 5208 Akomanga VI.
• PCTFE (Polychlorotrifluoroethylene):He pai mō ngā ratonga cryogenic. He pai te mahi mai i-196°C ki te +100°C.
• RPTFE (PTFE Whakakaha):Kua whakarei ake mō te roa me te pāmahana teitei ake. Awhe e tika ana:-25°C ki te +195°C, he tino pai mō ngā tono huringa teitei.
• PPL (Poropenirene):He kaha te mahi mō te mamaoa. Whakamahia i roto i te-25°C ki te +180°C.
• Viton® (FKM Fluoroelastomer):He rongonui mō tōna ātete ki ngā matū me te kaha whānui ki te pāmahana (-18°C ki te +150°C). Whakamahia kia tūpato me te mamaoa/wai.
• Hiraka (VMQ):He tino pai te toro atu ki te pāmahana teitei me te kore e taea te whakamahi matū (-100°C ki te +300°C), he maha ngā wā e hiahiatia ana te whakamaroke i muri i te hanga kia tino kaha ai.
• Buna-N (Nitrile Rubber – NBR):He kōwhiringa maha, he kōwhiringa ōhanga hoki mō te wai, te hinu, me ngā wahie (-18°C ki te +100°CHe ātete pai ki te pakū.
• EPDM (Ethylene Propylene Diene Monomer):He tino pai mō te ātete ki te ozone, te huarere, me ngā tono HVAC (-28°C ki te +120°C). Āta karohia ngā warowaihā.
• MOC / MOG (Ngā Hiko PTFE Kī tonu i te Waro):Ka whakarei ake i te pumau me te ātete ki te kakahu. Ko ngā whānuitanga MOC/MOG te tikanga-15°C ki te +195°C.
• MOM (PTFE Whakakī Waro Kua Whakarerekētia):Kua arotauhia mō te mau, te whānuitanga-15°C ki te +150°C.
• PA6 / PA66 (Nairona):He pai mō te pēhanga me te kakahu (-25°C ki te +65°C).
• POM (Acetal):Te kaha me te pakari teitei (-45°C ki te +110°C).
• PEEK (Polyetheretherketone):He pūhui mahi-teitei kounga teitei. He pāmahana tino pai (-50°C ki te +260°C), te pēhanga, te kakahu, me te ātete matū. He tino ātete ki te waikura (wai wera/mamahu).
Ngā Nohoanga Takirere Pōro Hiri Mārō (He mea hanga ki te konganuku me te koranu):
• Kowiri tira + Kāpiro Tungsten:He otinga pakari mō ngā pāmahana teitei (-40°C ki te +450°C).
• Kohanga Maama (hei tauira, Stellite) + Ni55/Ni60:He tino pai te mau me te ātete ki te pāmahana tino kino (-40°C ki te +540°C).
• Koranu Pāmahana-Teitei (hei tauira, Inconel, Hastelloy) + STL:I hangaia mō ngā ratonga tino kino (-40°C ki te +800°C).
Whakaaroaro Arohaehae:Ko ngā rauemi kua whakarārangihia i runga ake nei e tohu ana i ngā kōwhiringa noa.Nohoanga Takirere Pōrome hangai te kōwhiringa ki tengā tikanga whakahaere motuhake(pāmahana, pēhanga, reo, auau huringa, me ētahi atu) o ia tono. He maha atu ngā rauemi motuhake hei whakatutuki i ngā whakaritenga ahurei i tua atu i te pāmahana anake. Me kōrero tonu ki ngā kaihanga takirere mō ngā taunakitanga rauemi tika e hāngai ana ki tō pūnaha. Ko te tikaNohoanga Takirerehe mea nui kitakirere pōrote mahi me te roa o te ora.
