Ngā takirere pūrerehuaHe mahi nui tā rātou ki te whakahaere i te rere o ngā wai me ngā hau. I roto i ngā momo takirere pūrerehua, ko ngā takirere pūrerehua me ngā takirere waferngā takirere pūrerehuae rua ngā kōwhiringa e whakamahia whānuitia ana. He mahi ahurei tā ngā momo takirere e rua, ā, he pai mō ngā tono motuhake.TWSKa tūhuratia e mātou ngā āhuatanga ōrite me ngā rerekētanga o ēnei i roto i tēnei tuhinga, me te tumanako ka āwhina i a koe ki te whakatau whai whakaaro i te wā e whiriwhiri ana i te takirere tika.
I. Ngā āhuatanga ōrite i waenganui i a rātou.
1. Te mahiPte kaupapa
Mā ngā takirere pūrerehua momo-wafer me ngā takirere pūrerehua momo-tu ka whakahaere i te tere rere o te reo mā te hurihuri i te kōpae takirere. Ko te koki hurihuri o te kōpae takirere ka taea anake i waenga i te 0 ki te 90 nekehanga, arā, ka tuwhera katoa te takirere i te 90 nekehanga, ka kati katoa i te 0 nekehanga. Koinei te mātāpono mahi a ngā takirere pūrerehua.
2. TauaKanohi ki te Kanohi
He momo angiangi te hoahoa o te takirere pūrerehua angiangi me te takirere pūrerehua lug, he iti ake te wāhi e nohoia ana e rātou, ā, he pai hoki mō te tāutanga ki te pūnaha paipa he iti te wāhi.
3. Hoahoa paerewa:
E tutuki ana ēnei e rua i ngā paerewa ahumahi o te ao, he ngāwari te hono atu ki ngā here paerewa, ā, ka taea hoki te whakakapi ngāwari ki ngā pūnaha o nāianei.

Tuarua.He ahas te rerekētanga?
Ko ngā takirere pūrerehua momo angiangi me ngā takirere pūrerehua momo pūweru e pā ana ki te momo hononga o ngā takirere pūrerehua, he rite tonu te roa o te hanganga me ngā kaupapa rite tonu, engari he rerekētanga nui i roto i te hoahoa, te tāutanga, te tono, te utu, me ētahi atu āhuatanga.
1.HoahoaDngā rerekētanga
Takirere pūrerehua: He mea hanga ngā pito e rua o te tinana takirere ki ngā takirere miro, he pai ake mō te whakatika i te takirere.
Takirere pūrerehua angiangi: Engari, kāore he whakaurunga miro, engari he mea whakau i waenganui i ngā parirau e rua, me ngā pūtu e haere ana i roto i te parirau paipa me te tinana o te pūtu hei whakau. Arā, he mea hanga mā te pēhanga o ngā pūtu e pēhi ana i te parirau paipa.
2.TāutangaPtukanga
He pai ngā takirere pūrerehua lug mō ngā paipa e hiahia ana kia tiakina auau, kia wetewetehia auau rānei. He ngāwari te tāuta me te wetewete i ngā whakaurunga miro, me te kore e kino te pūnaha paipa katoa. Ka taea te tāuta i te takirere pūrerehua e pupū ake ana ki te pito o te paipa, ā, ka taea te whakamahi hei takirere whakamutunga.
- Me whakarite kia tika te tūnga o ngā lugs ki ngā pūtu flange kia kore ai e pēhia te tinana o te takirere.
- Whakamahia ngā rauemi gasket e tika ana ina hiahiatia hei ārai i te turuturu, inā koa i roto i ngā pūnaha pēhanga reo.
- Whakakīia ngā pūtu kia ōrite te pēhanga i roto i te takirere.
He pai ake ngā takirere pūrerehua wafer mō te hono i ngā pito e rua o ngā paipa i ngā wā he iti te wāhi, engari kāore e taea te whakamahi hei takirere whakamutunga nā te mea ka taea e rātou te wehe.
- Manatokohia te hototahitanga o ngā flange (hei tauira, ANSI, DIN) kia mau ai te hiri.
- Āta karohia te whakakukū rawa o ngā pūtu o te flange hei ārai i te rerekētanga o te āhua o te tinana o te mīhini.
- Kua tāuta ki roto i te pūnaha me te iti o te wiri o te paipa hei ārai i te wetekina.
3. Tikanga Hiri.
Ka whakakaha ake te hiri o te takirere pūrerehua nā ngā hononga miro me ngā pūtu haumaru, kia kore ai e turuturu te mahi, kia kore ai hoki e hoki whakamuri te wai.
Engari, ko te takirere pūrerehua momo wafer e whakawhirinaki ana ki te pēhanga i waenga i ngā flange e rua hei whakatutuki i te hiri pono, nō reira me tāuta kia tino rite ki te paipa kia kore ai e hē te tūnga me te turuturu.
4. DN&PN
- Ko ngā takirere pūrerehua he iti ake i te DN600, ā, ka taea te whakamahi i ngā takirere pūrerehua kotahi-whāriki mō ngā diameter nui ake. He pai mō ngā āhuatanga kei reira te pēhanga he ≤ PN16.
-He nui ake te whānui o te takirere pūrerehua tuitui, ā, ka taea e ia te tu atu ki ngā taumata pēhanga teitei ake, tae atu ki te PN25, nā te mea he haumaru ake te tāutanga o te takirere pūrerehua tuitui.
5. Ctuatahi
He rerekē te utu o ngā takirere pūrerehua lug me ngā takirere pūrerehua wafer.
He iti ake te ohanga o ngā takirere pūrerehua angiangi nā te mea he māmā ake ngā hoahoa, he māmā ake te tukatuka, ā, he iti ake ngā rauemi e hiahiatia ana.
Me miro te takirere pūrerehua, nō reira he tino uaua te tukanga miihini.
III. Cwhakamutunga
E whakamahia ana ngā takirere pūrerehua me ngā takirere pūrerehua wafer hei whakahaere i te rere o te wai, engari he rerekētanga nui kei waenganui i ēnei e rua i roto i te hoahoa, te tāutanga, te hiri, te diameter, te whakatauranga pēhanga, me te utu. I te wā e whiriwhiri ana, ka taea te whakatau i runga i ngā hiahia motuhake: ki te hiahiatia he wetewete me te tiaki pinepine, he mea tika kia whiriwhiria he momo taringa e pupū ake ana; ki te iti te wāhi, ā, he āwangawanga te utu, he pai ake te hoahoa wafer. Mā te mārama ki ēnei rerekētanga ka āwhina i a koe ki te whiriwhiri i ngā takirere hototahi ake, me te whakatutuki i te whakahaere rere pai me te pono.TWSehara i te mea he hoa pono anake mō te kounga teiteingā takirere pūrerehua, engari he kohinga hangarau hohonu anō hoki me ngā otinga pakari i roto i ngā mara ongā takirere kuaha, takirere tirotiro, takirere tuku hau, me ētahi atu. Ahakoa he aha ngā hiahia o te whakahaere wai, ka taea e mātou te whakarato ki a koe he tautoko takirere ngaio me te katoa. Mena kei a koe he hiahia ki te mahi tahi, ki te kōrero hangarau rānei, tēnā koa whakapā mai ki a mātou i ngā wā katoa.
