te kaupapa mahi
A takirere pūrerehuahe momo takirere e whakatika ana i te rere o te reo mā te whakatuwhera, te kati rānei mā te huri whakamuri, whakamuri hoki, tata ki te 90 nekehanga. Haunga tōna hoahoa māmā, tōna rahi iti, tōna mama, tōna whakamahinga rauemi iti, tōna ngāwari ki te tāuta, tōna taipana taraiwa iti, me tōna tere o te whakahaere, ko tetakirere pūrerehuahe pai hoki te mahi a te takirere mō te whakahaere rere, ā, he pai hoki te katinga me te hiri. tētahi o ngā momo takirere tere rawa atu. Ko te whakamahinga ongā takirere pūrerehuahe mea noa.

Kei te piki haere tonu te whānuitanga me te nui haere o ōna whakamahinga, ā, kei te neke haere ki te pāmahana teitei, te pēhanga teitei, te whānui nui, te hiri teitei, te roa o te ora, ngā āhuatanga whakarerekētanga tino pai, me te maha o ngā mahi a te takirere. Inaianei he taumata teitei tōna pono me ētahi atu āhuatanga mahi.

Kua pai ake te mahi a ngā takirere pūrerehua nā te whakamahinga o te rapa hangai ātete ki ngā matū. Nā te mea he ātete ki te waikura, he ātete ki te horo, he rahi pumau, he pakari pai, he ngāwari ki te hanga, me te utu iti, ka taea te whiriwhiri i te rapa hangai me ngā āhuatanga rerekē i runga i ngā whakaritenga tono rerekē hei whakatutuki i ngā tikanga mahi o ngā takirere pūrerehua.

I te mea he kaha te ātete o te polytetrafluoroethylene (PTFE) ki te waikura, he pumau te mahi, he ātete ki te koroheketanga, he iti te tauwehenga o te waku, he ngāwari te hanga, me te pumau o te rahi, ka taea te whakarei ake i tōna mahi whānui mā te whakakī me te tāpiri i ngā rauemi e tika ana hei whakatutuki i te kaha me te waku pai ake. He ngoikoretanga ētahi o ngā rapa hangai, engari ko ngā rauemi mō te hiri i te takirere pūrerehua he iti ake te tauwehenga ka taea te karo i aua ngoikoretanga. Hei whakapai ake i te mahi a ngā takirere pūrerehua, kua whānuitia te whakamahi i ngā rauemi polymer ngota teitei, pērā i te polytetrafluoroethylene, me ā rātou rauemi whakakī kua whakarerekētia. Kua whakahoutia inaianei, ā, kua hangaia he takirere pūrerehua me te whānuitanga pāmahana me te pēhanga nui ake, te mahi hiri pono, me te roa ake o te ora whai hua.

Kua tino whanake haere ngā takirere pūrerehua hiri-whakarewa kia tutuki ai ngā hiahia o ngā mahi ahumahi pēnei i te pāmahana teitei me te pāmahana iti, te horo kaha, me te roa o te ora. Kua whakamahia whānuitia ngā takirere pūrerehua hiri-whakarewa i roto i ngā mara ahumahi pēnei i te pāmahana teitei me te pāmahana iti, te horo kaha, me te roa o te ora nā te whakamahinga o te ātete pāmahana teitei, te ātete pāmahana iti, te ātete waikura kaha, te ātete horo kaha, me ngā rauemi koranu kaha-teitei. Hei whakatairanga i te hangarau takirere pūrerehua, i puta tuatahi mai ngā takirere pūrerehua whānui (9–750mm), te pēhanga teitei (42.0MPa), me te awhe pāmahana whānui (-196–606°C).

He iti te ātete o te rere o te takirere pūrerehua ina tuwhera katoa. He maha ngā whakamahinga o ngā takirere pūrerehua i roto i te mara o te whakahaere i te whānui nui nā te mea ka taea e rātou te whakahaere i te rere mārie i ngā whakatuwheratanga i waenga i te 15° me te 70°.

Ka taea te whakamahi i te nuinga o ngā takirere pūrerehua me ngā mea kei roto ngā matūriki totoka iri, nā te mea ka neke te pereti pūrerehua i roto i te nekehanga muru. Ka taea hoki te whakamahi mō ngā mea kirikiri me ngā mea paura, i runga i te kaha o te hiri.

He pai ngā takirere pūrerehua mō te whakahaere i te rere. I te wā e whiriwhiri ana i tētahi takirere pūrerehua, he mea nui kia tino whakaarohia te pānga o te ngaronga pēhanga ki te pūnaha paipa me te kaha o te pereti pūrerehua ki te tu atu i te pēhanga o te reo paipa ina kati ana nā te mea he nui te ngaronga pēhanga o te takirere pūrerehua i roto i te paipa, tata ki te toru ngā wā i te takirere kuaha. Me whai whakaaro hoki ki te pāmahana whakahaere o te rauemi nohoanga rapa i ngā pāmahana teitei.

He poto te hanganga o te takirere pūrerehua, ā, he iti te teitei whānui. Ka tere te whakatuwhera me te kati, ā, he pai ngā āhuatanga whakahaere wai. Ko te hanga takirere whānui te mea tino pai mō te hoahoa hanganga o te takirere pūrerehua. Ko te taahiraa tino nui ki te whiriwhiri i tētahi takirere pūrerehua ka mahi tika, ka whai hua hoki ina whakamahia hei whakahaere i te rere, ko te whiriwhiri i te momo me te whakatakotoranga tika.

Ko ngā takirere pūrerehua e tūtohutia ana kia whakamahia i roto i te whakawhāiti, te whakahaere i te mana, me ngā pāpāho paru ina hiahiatia he roa hanganga poto, he tere whakatuwhera me te kati tere, me te tapahi pēhanga iti (he rerekētanga pēhanga iti). Ka taea te whakamahi i ngā takirere pūrerehua me ngā pāpāho whakakoi, ngā hongere iti te diameter, te haruru iti, te cavitation me te vaporization, te iti o te turuturu o te hau, me te whakatikatika tūranga-rua. Te whakatikatika i te kātere ina mahi ana i raro i ngā āhuatanga rerekē, pēnei i te hiri piri, te kakahu tino nui, te pāmahana tino iti, me ētahi atu.
