Takirere Pūrerehua Porowhita Noho Rapa
✧ Whakaahuatanga
Ko te takirere pūrerehua porowhita me te hoahoa noho-rapa he momo takirere ahumahi e whakamahia whānuitia ana hei whakahaere, hei wehe rānei i te rere o ngā wai i roto i ngā paipa. Anei tētahi tirohanga poto mō ngā āhuatanga matua me ngā āhuatanga o tēnei momo takirere: Hoahoa Porowhita: I roto i te takirere pūrerehua porowhita, ka whakaritea te pokapū o te kakau me te pokapū o te kōpae, ka hangaia he āhua porowhita porowhita ina kati te takirere. Mā tēnei hoahoa ka taea te ara rere ngāwari me te iti o te hekenga pēhanga puta noa i te takirere. Takirere Pūrerehua: Ka whakamahia e te takirere he kōpae, he "pūrerehua" rānei, e piri ana ki te kakau pokapū. Ina tuwhera katoa te takirere, ka whakanohoia te kōpae kia rite ki te ahunga o te rere, ka taea te rere kore aukati. Ina kati te takirere, ka hurihia te kōpae kia poutū ki te rere, ka ārai i te rere. Noho-Rapa: Kei te takirere he nohoanga rapa, e mahi ana hei huānga hiri i waenga i te kōpae me te tinana takirere. Mā te nohoanga rapa ka kati pai te takirere ina kati te takirere, ka ārai i te turuturu me te whakarato i te hiri piri-mirumiru. Ngā Whakamahinga e tika ana: He maha ngā whakamahinga o tēnei momo takirere i roto i te whānuitanga o ngā ahumahi, tae atu ki te maimoatanga wai me te wai para, ngā pūnaha HVAC, te tukatuka matū, te hinu me te hau, te whakaputa hiko, me ngā tono ahumahi whānui. Te Whakaoho: Ka taea te whakahaere ā-ringa i ngā takirere pūrerehua porowhita mā te whakamahi i te rīwhi ringa, i te kaiwhakahaere taputapu rānei, ka taea rānei te whakahaere aunoa me ngā kaiwhakaoho hiko, hau rānei mō te mahi mamao, aunoa rānei. I te wā e tohua ana he takirere pūrerehua porowhita me te hoahoa noho-rapa, me āta whakaaro ki ngā āhuatanga pēnei i te rahi o te takirere, te whakatauranga pēhanga, te awhe pāmahana, ngā āhuatanga rere, me te hototahi o ngā rauemi ki te pāpāho e whakahaerea ana.
✧ Ngā Āhuatanga o te Takirere Pūrerehua Porowhita e Nohoia ana e te Rapa
1. iti, māmā hoki, ngāwari ki te wetewete me te whakatika, ā, ka taea te tāuta ki tētahi tūranga.
2. He hanganga māmā, he kiato, he iti te taipana whakahaere, he tere te whakatuwhera i te hurihanga 90°.
3. Ko ngā āhuatanga rere he tika, he pai te mahi whakatikatika.
4. Ko te hononga i waenga i te pereti pūrerehua me te kakau takirere e whakamahi ana i tētahi hanganga kore-pine hei wikitoria i te pūwāhi turuturu ā-roto pea.
5. Ko te porowhita o waho o te pereti pūrerehua he porowhita te āhua, e whakapai ake ana i te mahi hiri me te whakaroa i te roa o te ora o te takirere, ā, kāore he turuturu me te whakatuwheratanga me te kati pēhanga neke atu i te 50,000 ngā wā.
6. ka taea te whakakapi i te hiri, ā, he pono te hiri hei whakatutuki i te hiri rua-ara.
7. Ka taea te rehu i te pereti pūrerehua kia rite ki ngā hiahia o te kaiwhakamahi, pērā i te nairona, te polytetrafluoroides rānei.
8. ka taea te hoahoa i te takirere hei hononga flange me te hononga rawhi.
9. ka taea te whiriwhiri i te aratau taraiwa ā-ringa, hiko, hau rānei.
✧ Ngā Painga o te Takirere Pūrerehua Porowhita e Nohoia ana e te Rapa
I te wā e whakatuwheratia ana, e kati ana hoki te takirere porowhita maitai hanga, nā te mea he iti ake te waku i waenga i te kōpae me te mata hiri o te tinana takirere i tērā o te takirere kuaha, ka ātete ki te kakahu.
He poto noa te whiu whakatuwheratanga, te whiu kati rānei o te kakau takirere, ā, he tino pono te mahi tapahi, ā, nā te mea he rite te huringa o te putanga nohoanga takirere ki te whiu o te kōpae takirere, he tino pai mō te whakatikatika i te tere rere. Nō reira, he tino pai tēnei momo takirere mō te tapahi, te whakahaere rānei me te whakawhāiti.
