Ko te kaupapa o te takirere pūrerehua UPVC hauhautanga he whakatutuki i ngā hiahia o ngā wā rerekē. Ko te kaupapa o te hauhautanga houtakirere pūrerehua UPVCHe 0-90 nekehanga, he 0-120 nekehanga, me te 0-180 nekehanga ngā takirere pūrerehua hau UPVC. Ka taea hoki e ngā takirere pūrerehua hau UPVC te whakarato i ngā kaiwhakaoho whiu koki pērā i te 0-140 nekehanga. 0-160 nekehanga, me ētahi atu, ina tīpakohia te takirere pūrerehua hau UPVC, ka tāpirihia te uara haumaru ki te taipana kua whakatauhia hei whakanui ake i te uara haumaru mā te 25%, ka whakanui ake te reo wai paru kore-hinuhinu UPVC takirere pūrerehua hau UPVC i te uara haumaru mā te 30%, ka whakanui ake te reo hau maroke kore-hinuhinu UPVC takirere pūrerehua hau 40%, ka whakanui ake te reo rauemi matūriki kawe hau kore-hinuhinu i te uara haumaru mā te 60%, ā, ka whakanui ake te uara haumaru mā te takirere pūrerehua hau UPVC i te uara haumaru mā te 20% mō te reo hinu ma, iti-waku. Ko te uara haumaru kua whakahuatia i runga ake nei he taunakitanga ariā nā te kamupene, ā, he mea noa iho mō te tohutoro. Nō Shanghai Huanqi te mana pupuri whakatika. Kāore he pānui e whakamōhiotia ana mō te whakarerekētanga o ngā ihirangi o tēnei tuhinga, ā, kei te kamupene te mana whakamutunga ki te whakamārama.
Ko te pūwhakaoho hau o te takirere pūrerehua UPVC hau (e mōhiotia whānuitia ana ko te pane hau) e kiia ana hoki ko te pūwhakaoho hau, ko te taputapu hau rānei. He pūwhakaoho e whakamahi ana i te pēhanga hau kōpeke hei akiaki i te whakatuwhera me te kati, te whakarite rānei i ngā takirere.Ngā takirere pūrerehua UPVChe mea hanga te nuinga mai i ngā rango hau. Ko ngā piston, ngā toki taputapu, ngā taupoki pito, ngā hiri, ngā tīwiri, me ētahi atu, ko ngā kaiwhakaoho hau e whakamahia whānuitia ana me ngā momo takirere, hauNgā takirere pūrerehua UPVC, kei roto hoki ngā tohutohu whakatuwhera, ngā rohe whiu, ngā takirere solenoid, ngā tūnga, ngā wāhanga hau, te pukapuka ā-ringa. Ko te tikanga, te urupare tohu me ētahi atu wāhanga, te whakatuwheratanga, te kati o te takirere, te nui hei whakatuwhera, te nui hei kati, e whakahaerehia katoatia ana e te hau kōpeke. Ko te mahi a te takirere pūrerehua UPVC hau Shanghai Huanqi. Ka taea te wehewehe i ngā kaiwhakahaere hau ki te mahi kotahi me te mahi rua i runga i te āhua o te mahi. Ko ngā kaiwhakahaere mahi rua he whakatuwheratanga hau me te kati hau, arā, ina whakatuwheratia te hau, ka kati te hau, ā, ina ngaro te pūtake hau, Kāore he mahi, ka noho ki te wāhi, ā, ko ngā kaiwhakahaere mahi kotahi he mahi whakahoki puna. I te nuinga o te wā, he momo kati noa me te momo tuwhera noa, arā, he tuwhera te hau. Ina ngaro te pūtake hau, ka tautuhi aunoa te takirere pūrerehua UPVC hau ki tōna āhua tīmatanga. He maha ake te whakamahinga i roto i ngā āhuatanga mahi, ā, ka taea te kati tere, te whakatuwhera rānei i te takirere ina puta he pakaru ohorere ina ngaro te puna hau.

Te mātāpono mahi o te takirere pūrerehua hau UPVC hau-rua:

Ko te takirere pūrerehua hau UPVC, ina tomo te pēhanga pūtake hau ki te kōhao i waenganui i ngā piston e rua o te rango mai i te putanga hau (2), ka wehea ngā piston e rua ka neke ki ngā pito e rua o te rango. Ka akiakihia e te whatanga te pou whakaputa (taputapu) kia huri i te taha maui, ko te takirere pūrerehua hau UPVC, i te ritenga ke, ina tomo te pēhanga pūtake hau ki ngā rūma hau i ngā pito e rua o te rango mai i te putanga hau (4), ka nekehia e te takirere pūrerehua hau UPVC ngā piston e rua ki te ahunga o waenganui o te rango, ā, ka tukuna te hau ki te rūma hau waenga mā te putanga hau (2), ā, ka meinga e te takirere pūrerehua hau UPVC ngā whatanga piston e rua kia akiakihia te pou whakaputa (taputapu) kia huri i te taha maui. (Mēnā ka tāutahia te piston ki te ahunga ke, ka huri te pou whakaputa hei huri whakamuri)
