Kei te tāuta koe i tētahi paipa wai hou, ā, kei te hopu koe i tētahi takirere PVC. Engari ki te kore koe e mōhio ki tōna rohe pēhanga, kei te tūpono koe ki tētahi pakaru nui, ki tētahi waipuke nui, me te utu nui mō te whakaweto o te pūnaha.
Ko te takirere pōro PVC Paerewa 40 e whakatauria ana kia taea te whakahaere i te mōrahi o te 150 PSI (Pauna ia Inihi Tapawhā) i te 73°F (23°C). Ka tino heke te pēhanga i te pikinga o te pāmahana wai, nō reira he mea nui kia tirohia ngā whakaritenga a te kaihanga.
Ko taua tau, 150 PSI, te whakautu māmā. Engari he uaua ake te whakautu tūturu, ā, ko te mārama ki tēnei te mea nui ki te hanga i tētahi pūnaha haumaru, pono hoki. He maha āku kōrero ki a Budi, he kaiwhakahaere hoko i Initonīhia mō tēnei. Ka whakangungu ia i tana tīma ki te pātai ki ngā kiritaki ehara i te mea "he aha te pēhanga e hiahiatia ana e koe?" engari "he aha te pāmahana?" me te "me pēhea te aukati i te rere?" Ka taea e te papu te hanga i ngā pikinga pēhanga i runga ake i te toharite o te pūnaha. Ko te takirere he wāhanga noa iho o te pūnaha katoa. Ko te mōhio ki te nui o te pēhanga ka taea e ia te whakahaere ehara i te mea ko te pānui i tētahi tau anake; engari ko te mārama ki te whanonga o tō pūnaha i te ao tūturu.
He aha te whakatauranga pēhanga o te takirere PVC?
Ka kite koe i te "150 PSI" kua tāia ki te takirere, engari he aha te tikanga o tēnā? Mēnā ka whakamahia i roto i ngā āhuatanga hē, ka pakaru pea, ahakoa te āhua iti o te pēhanga.
Ko te whakatauranga pēhanga o te takirere PVC, ko te 150 PSI te tikanga mō te Wāhanga 40, ko tōna pēhanga mahi haumaru mōrahi i te pāmahana rūma. I te pikinga o te pāmahana, ka ngohengohe te PVC, ā, ka tino heke tōna kaha ki te whakahaere pēhanga.
Whakaarohia te kaha o te pēhanga i roto i tētahi āhuatanga tino pai. I te pāmahana rūma whakamarie o te 73°F (23°C), he kaha, he pakari hoki te takirere PVC ma. EngariHe kirihou wera te PVC, arā, ka ngawari haere i te wera. Koinei te ariā tino nui hei mārama: me "whakaiti" te pēhanga mō ngā pāmahana teitei ake. Hei tauira, i te 100°F (38°C), tera pea ka haumaru noa te takirere 150 PSI tae noa ki te 110 PSI. Kia tae koe ki te 140°F (60°C), kua heke tōna whakatauranga mōrahi ki te 30 PSI. Koia te take he mea noa te PVC paerewa mō ngā raina wai matao. Mō ngā pēhanga teitei ake, mō ngā pāmahana paku teitei ake rānei, me titiro koe kiRārangi 80 PVC(he hina pouri te nuinga), he matotoru ake ngā pakitara, ā, he teitei ake te pēhanga tīmatanga.
Te Whakatauranga Pēhanga PVC me te Pāmahana
| Te pāmahana wai | Pēhanga Mōrahi (mō te Takirere 150 PSI) | Te Kaha i Pupuritia |
|---|---|---|
| 73°F (23°C) | 150 PSI | 100% |
| 100°F (38°C) | ~110 PSI | ~73% |
| 120°F (49°C) | ~75 PSI | ~50% |
| 140°F (60°C) | ~33 PSI | ~22% |
He aha te rohenga pēhanga mō te takirere pōro?
E mōhio ana koe kei raro iho i te rohe te pēhanga pumau o tō pūnaha. Engari mā te katinga ohorere o te takirere ka puta he pikinga pēhanga ka pupuhi atu i taua rohe, ka pakaru tonu.
Ko te rohe pēhanga kua whakahuatia he pēhanga pumau, kāore e pāngia e te ru. Kāore tēnei rohe e whai whakaaro ki ngā kaha hihiri pēnei i tehama wai, he puhaketanga pēhanga ohorere e ngāwari ai te pakaru o te takirere he nui ake ngā pēhanga.
Ko te hama wai te kaikōhuru puku o ngā wāhanga paipa. Whakaarohia he paipa roa kī tonu i te wai e tere haere ana. Ina katihia e koe te takirere, me mutu tonu te wai e neke ana. Ka hangaia e te nekehanga he ngaru ru nui e hoki ana i roto i te paipa. Ka taea e tēnei pikinga pēhanga te 5 ki te 10 ngā wā o te pēhanga pūnaha noa. Ka taea e te pūnaha e rere ana i te 60 PSI te pāngia e te pikinga o te 600 PSI mō tētahi wā poto. Kāore he takirere pōro PVC paerewa e kaha ki te tu atu ki tēnā. Ka kī tonu ahau ki a Budi kia whakamahara i ana kiritaki kirimana mō tēnei. Ina rahua te takirere, he ngāwari te whakapae i te hua. Engari he maha ngā wā, ko te raruraru he hoahoa pūnaha kāore e aro ki te hama wai. Ko te ārai pai ko te kati mārire i ngā takirere. Ahakoa he takirere pōro huri-hauwhā, he rerekētanga nui te whakahaere maeneene i te kakau mō te hēkona, e rua rānei, kaua e kati.
E hia te pehanga ka taea e te PVC te tu atu?
Kua whiriwhiria e koe te takirere tika, engari me pēhea te paipa? Ko te kaha o tō pūnaha he rite tonu ki tōna hononga ngoikore, ā, he rite tonu te kino o te pakaru o te paipa ki te pakaru o te takirere.
Ko te nui o te pēhanga ka taea e te PVC te tu atu, e whakawhirinaki ana ki tōna "matū" pakitara, ki tōna matotoru rānei. He iti ake te pēhanga o ngā paipa PVC Paerewa Paerewa Paerewa 40 i ngā paipa Paerewa Paerewa 80 matotoru ake, ā-ahumahi ake.
He hapa noa te arotahi ki te whakatauranga o te takirere anake. Me taurite ō wāhanga. Ko te paipa Hōtaka 40 2-inihi, te paipa mā e kitea ana i ngā wāhi katoa, he 140 PSI te nuinga o te wā e whakataurangahia ana. Ko te paipa Hōtaka 80 2-inihi, he matotoru ake ngā pakitara, ā, he hina pouri te nuinga, he 200 PSI te nui ake. Kāore e taea e koe te whakanui ake i te kaha pēhanga o tō pūnaha mā te whakamahi noa i tētahi takirere kaha ake. Mena ka tāutahia e koe he takirere Hōtaka 80 (240 PSI te whakatauranga) ki runga i tētahi paipa Hōtaka 40 (140 PSI te whakatauranga), ko te pēhanga haumaru mōrahi o tō pūnaha he 140 PSI noa iho. Ko te paipa te hononga ngoikore rawa atu. Mō tētahi pūnaha, me tautuhi koe i te whakatauranga pēhanga o ia wāhanga—ngā paipa, ngā hononga, me ngā takirere—me te hoahoa i tō pūnaha huri noa i te wāhanga iti rawa te whakatauranga.
Whakataurite i te Maramataka Paipa (Tauira: PVC 2-inihi)
| Āhuatanga | Rārangi 40 PVC | Rārangi 80 PVC |
|---|---|---|
| Tae | He mā te nuinga o te wā | Te nuinga o te wā he hina pouri |
| Matotoru o te Pakitara | Paerewa | Matotoru ake |
| Whakatauranga Pēhanga | ~140 PSI | ~200 PSI |
| Te Whakamahinga Noa | Ngā Paipa Whānui, Ngā Whakamakuku | Ahumahi, Pēhanga Teitei |
He pai ngā takirere pōro PVC?
Ka titiro koe ki tētahi takirere kirihou māmā, ā, ka whakaaro koe he iti te utu. Ka taea e koe te whakawhirinaki ki tēnei wāhanga iti te utu hei wāhanga pono mō tō pūnaha wai nui?
Āe, kounga teiteiNgā takirere pōro PVChe tino pai mō tā rātou mahi i whakaritea. Ehara i te kaha rawa te mea nui, engari ko tōna ātete katoa ki te waikura, ā, nā tēnei ka nui ake tō rātou pono i te konganuku i roto i ngā mahi maha.
Ko te whakaaro mō te "iti o te utu" i ahu mai i te whakataurite i te PVC ki te konganuku. Engari kāore tēnei i te mārama ki te kaupapa. I roto i te maha o ngā tono wai, inā koa i roto i te ahuwhenua, te whakatipu ika, te puna kaukau rānei, ko te waikura te tino take o te pakaru. Ka waikura, ka mau tonu te takirere parahi, rino rānei i roto i te wā. Kāore e pērā te takirere PVC kounga teitei, i hangaia mai i te kapia tauhou 100% me ngā nohoanga PTFE maeneene me ngā mowhiti-O koretake. Ka mahi maeneene mō ngā tau i roto i te taiao ka whakangaro i te konganuku. Ka toa a Budi i ngā kiritaki ruarua mā te whakahou i te pātai. Ehara te pātai i te "he pai te kirihou?" Engari ko te pātai "ka taea e te konganuku te ora i te mahi?" Mō te whakahaere wai matao, inā koa kei reira ngā matū, te tote rānei, ehara i te mea he kōwhiringa pai te takirere PVC pai te hanga; he kōwhiringa atamai ake, he pono ake, he whai hua ake hoki mō te wā roa.
Whakamutunga
Ka taea e te takirere pōro PVC te whakahaere i te 150 PSI i te pāmahana rūma. Ko tōna uara tūturu kei roto i te ātete ki te waikura, engari me whai whakaaro tonu ki te pāmahana me te hama wai mō te pūnaha haumaru, roa hoki.
