Ko te hoahoa taurite takirua—e kiia ana i ētahi wā ko te "takirere pūrerehua mahi teitei"—e whakauru ana i ngā taurite motuhake e rua:
- Wāhi Whakakore 1: Kei muri i te papa hiri kōpae te tuaka o te rakau, kia matara atu i te rārangi pokapū nohoanga.
- Wāhanga 2: Kua wehea te tuaka o te rakau mai i te rārangi pokapū o te poka paipa.
Ka hangaia e ēnei taupatupatu e rua he mahi cam i te wā e hurihuri ana. Ina tīmata te whakatuwheratanga o te takirere, ka ara ake te kōpae mai i te nohoanga tata tonu - i roto i te 7-10 nekehanga tuatahi o te nekehanga. I te toenga o te whiu 90-tohu, ka huri te kōpae me te kore e pa ki te nohoanga, ka whakakore i te waku me te kakahu.

Ngā Pātai Auau (FAQ)
Āe, engari me ētahi herenga. Ka tukuna e ngā takirere pūrerehua mahi-teitei takirua ngā āhuatanga rere raina puta noa i te 90 nekehanga o te hurihanga, e pai ai mō te whakarerekē i ngā tono whakahaere. Heoi, ko te whakawhāiti i ngā whakatuwheratanga tino iti (i raro i te 15–20%), i ngā pēhanga rerekētanga teitei rānei, ka arahi pea ki te cavitation i roto i te ratonga wai. Ka whakaratohia e ngā takirere whakawhāiti takitoru te mahi whakawhāiti pai ake nā te ōwehenga whakahaere teitei. Mō te whakahaere whakawhāiti tika, tirohia ngā ānau tauwehenga rere (Cv) a te kaihanga me ngā raraunga cavitation mō te rahi me te whakapaipai o te takirere motuhake.
Kāhua angiangi:E herea ana te takirere ki waenganui i ngā parirau paipa e rua. Koinei te whirihoranga tino whai hua engari kāore e taea te tango i ngā paipa o raro me te kore e whakaiti i te pēhanga o te pūnaha. He 20–40% te iti ake o te utu mō ngā takirere angiangi i ngā takirere lug o te rahi ōrite.
Kāhua pūtu:He miro ngā whakaurunga (ngā lug) o te tinana takirere i ngā taha e rua, e āhei ai te whakapiri motuhake ki ngā flanges o ia taha. Mā tēnei ka taea te mahi mutunga kore, arā, ka taea te tango i ngā paipa o raro i te mea kei te pēhanga tonu te taha o runga—he mea nui mō te urunga tiaki. Ka whakaratohia hoki e ngā takirere lug he kaha ā-ringa tāpiri i roto i ngā pūnaha e pāngia ana e te ahotea o ngā paipa.
E wātea ana ngā momo e rua i roto i ngā whirihoranga hiri e rua ngā taha.
Kōwhiria te taurite takitoru ina:
- Neke atu i te 260°C te pāmahana (te rohe mahi a ngā nohoanga PTFE/RPTFE)
- Ko te tono e hiahia ana kia kore rawa e turuturu te whakarewa-ki-te-whakarewa
- Ko te ratonga he wehenga mamaoa pāmahana teitei, he wehenga hauwai rānei, ā, me mātua whakarite te haumaru ahi.
- Ko te nui o ngā huringa e hiahia ana kia nui te ātete ki te kakahu
- Ka whakamahia te takirere i roto i te ratonga cryogenic (LNG, ethylene)—ka mahi pono ngā takirere taurite takitoru me ngā rauemi e tika ana i ngā pāmahana tino iti.
Kōwhiria te taurite takirua (paerewa mahi-teitei) ina:
- Kei raro iho i te 260°C ngā pāmahana
- He pai te hototahitanga matū o ngā nohoanga PTFE, ngā nohoanga PTFE whakapakari rānei
- Ko te roa o te huringa taurite (tekau mano ngā huringa) e tutuki ana i ngā whakaritenga
- He mea nui te iti o te utu whakapaipai tīmatanga
Kua whakaatuhia e ngā whakamātautau motuhake te kati-ā-pūpū i roto i ngā huringa neke atu i te 100,000 mō ngā takirere pūrerehua mahi-teitei takirua kounga teitei. Ka taea e ngā takirere takirua te whakatutuki i te roa ake o te ora ratonga—he maha ngā wā ka neke atu i te 250,000 huringa i roto i ngā āhuatanga ratonga taurite. Ko te ora huringa tuturu e whakawhirinaki ana ki ngā āhuatanga whakahaere, tae atu ki te pēhanga, te pāmahana, te ma o te wai, me te tere o te whakaoho.
Kāo. Ko tētahi painga matua o te hoahoa mahi-teitei ko te āheinga hiri rua-aronga pono. Kāore i rite ki te nuinga o ngā takirere pūrerehua porowhita, he ahunga rere pai pea kei runga i te tinana, ka mau tonu te mahi kati katoa a ngā takirere mahi-teitei ahakoa te aronga tāutanga. Mā tēnei ka māmā ake te tāutanga, ka whakaiti i te mōrearea o te tāutanga hē.
