Ngā Takirere Pūrerehua Ratonga Whānui
Ko tēnei momo takirere pūrerehua te paerewa whānui mō ngā tono tukatuka whānui. Ka taea e koe te whakamahi mō ngā tono e pā ana ki te hau, te mamaoa, te wai me ētahi atu wai, ngā hau rānei kāore e mahi ana i ngā matū. Ka tuwhera, ka kati hoki ngā takirere pūrerehua ratonga whānui me te kakau 10-tūnga. Ka taea hoki e koe te whakatuwhera me te kati aunoa mā te whakamahi i te whakaoho hau, hiko rānei hei whakahaere aunoa i te whakakā/whakaweto, te whakawhāiti me te wehewehe.
Ka hipokina te tinana e te nohoanga o te takirere kia kore ai ngā rauemi e tukatukahia ana e pā ki te tinana. He tino pai tēnei hoahoa nohoanga mō te mahi i roto i ngā mahi korehau. Ka rere te kakau o te takirere mā roto i te kōpae, ā, ka piri ki te kōpae mā te spline piri, me ngā pūwero e toru i runga, i raro hoki e mahi ana hei peera kakau.
Ko tētahi o ngā painga o ngā takirere pūrerehua ratonga whānui ko te māmā ake o te hoahoa, e āhei ai te hanga ritenga kia uru ki ngā tono tukanga paipa rerekē. Hei tāpiri, he momo elastomer rerekē te hiri, ā, ka taea e koe te whiriwhiri i tētahi momo elastomer e uru ana ki tō tahua. Ko te ngoikoretanga o ēnei takirere ko te kaha o te taipana, ā, kāore e taea e te rauemi nohoanga te tu atu i ngā pāmahana me ngā taumata pēhanga teitei ake i te 285 PSI. Kāore hoki e taea te whakamahi i roto i ngā tono nui ake, nā te mea he maha ngā rahi tae atu ki te 30 inihi.
Ngā Takirere Pūrerehua Mahi-Teitei
Ka taea e ngā takirere pūrerehua mahi-teitei te whakahaere i ngā mea katoa ka taea e ngā takirere pūrerehua ratonga whānui te tukatuka, engari he mea hanga kia tū atu ki ngā wai me ngā hau kāore e taea e ngā takirere ratonga whānui te aro atu. He mea hanga ēnei ki ngā nohoanga PTFE ka taea te whakahaere i ngā wai, ngā hau me te mamaoa e tauhohe ana ki ngā matū me ngā waikura. Ahakoa he mea hanga ngā takirere pūrerehua whānui ki ngā elastomers e ngawari ana ki te horo, ka whakamahia e ngā takirere pūrerehua mahi-teitei he rauemi pakari pērā i te graphite hei hiri i te nohoanga. Ko tētahi atu painga ko te rahi tae atu ki te 60 inihi kia taea ai te whakamahi mō ngā tono nui ake.
Ahakoa te momo rauemi kino e tukatukahia ana e koe, ka kitea e koe he takirere pūrerehua mahi-teitei e whakatutuki ana i ō hiahia. Mena kei te tūpono tō tono ki te puta o ngā tukunga rere, ka taea e koe te whakamahi i tētahi takirere pūrerehua mahi-teitei e whakaatu ana i ngā toronga hiri kakau hei whakahaere i ngā tukunga ātete-tauraki. Mena ka tukatukahia e ō paipa ngā pāmahana tino makariri, ka kitea e koe he takirere pūrerehua mahi-teitei me ngā toronga kaki pēhanga e taea ai te whakamahana i ngā paipa.
Ka kitea e koe ngā takirere pūrerehua mahi-teitei i hangaia ki te maitai waro, te maitai kore waikura, me ētahi atu konganuku. Ka whakarewaina ngā konganuku kia taea ai e te takirere te tu atu i ngā pāmahana iti iho i te -320 nekehanga F me te teitei ake i te 1200 nekehanga F, me te tu atu i ngā taumata pēhanga tae atu ki te 1440 PSI. Ko te nuinga o ngā takirere pūrerehua mahi-teitei he aukati kei roto i te tinana e ārai ana i te neke haere rawa, me te repe tākai ka taea te whakarite hei ārai i te turuturu o waho.
