Te mārama ki ngā rerekētanga i waenganui iNgā takirere Venturimengā takirere pūrerehuaHe mea nui tēnei hei whiriwhiri i te otinga whakahaere rere tika. Ka whakatauritea e tēnei aratohu ō rātou hanganga, ā rātou tono, ā rātou utu, me ētahi atu.
He aha te takirere Venturi
A takirere VenturiHe taputapu whakahaere rere tino tika i hangaia hei pupuri i te rere o te hau, i ngā tere rere wai rānei mā te whakamahi i te pānga Venturi. He korokoro whaiti tōna e whakateretere ana i te wai me te whakaiti i te pēhanga, e āhei ai te whakahaere tika me te kore e neke ngā wāhanga.
He aha te takirere pūrerehua
A takirere pūrerehuaHe takirere hurihuri hauwhā-hurihuri me te kōpae porohita e mau ana ki runga i te kakau hurihuri. Ka whakahaere i te rere mā te whakanoho i te kōpae kia poutū (katia) kia whakarara rānei (tuwhera) ki te reo. He māmā, he iti te utu, ā, he pai mō ngā tono whakaweto tere.
Hanganga me te Mātāpono Mahi
Takirere Venturi
- Hanganga:He ngongo whaiti, he korokoro whaiti, he putanga pēhanga, ā, kāore he wāhanga e neke ana.
- Mātāpono:E whakamahi ana i te mātāpono a Bernoulli—ka tere haere te wai i roto i te korokoro, ka puta he hekenga pēhanga hei whakahaere i te rere.
Takirere Pūrerehua
- Hanganga:Tinana porohita, kōpae hurihuri, rakau, me te kaiwhakaoho (ā-ringa, aunoa rānei).
- Mātāpono:Mā te hurihanga kōpae ka whakatika i te rere; mā te hurihanga 90° ka huaki, ka kati rānei te takirere.
Ngā Āhuatanga Whakahaere
| Āhuatanga | Takirere Venturi | Takirere Pūrerehua |
| Te tika | Teitei (rere tonu) | Taurite (kā/weto, whakahaere taketake rānei) |
| Tere o te Urupare | Āhuakore (kāore e hiahiatia he whakaoho) | Tere (mahi tere hurihanga-hauwhā) |
| Te hekenga o te pēhanga | Iti | Teitei ake (nā te aukati o te kōpae) |
Ngā horopaki tono
Takirere Venturi
- Ngā taiwhanga (ngā taupoki paowa, ngā rūma horoi).
- Ngā pūnaha HVAC e hiahia ana ki te rere o te hau pumau.
- Te inenga matū me ngā tere rere tika.
Takirere Pūrerehua
- Ngā whare whakaora wai.
- Ngā paipa nui (hinu, hau, wai).
- Ngā tukanga ahumahi e hiahia ana kia tere te whakamutu.
Ngā Utu Tiaki
- Takirere Venturi:He iti te tiaki (kāore he wāhanga neke). He teitei ake te tīmatanga.utunā te hangarau tino tika.
- Takirere Pūrerehua:He utu whaitake i te tīmatanga. Tērā pea me whakakapi te kōpae/hiri i ia wā.
Wāhi Tāutanga
- Takirere Venturi:He hoahoa raina kiato, ka uru ki ngā wāhi kuiti.
- Takirere Pūrerehua:Me wātea te kōpae mō te hurihanga; he matotoru ake i ngā rahi nunui.
Ngā Kaihanga Matua i Haina
Kei Haina te manaaki i ngā toa matuangā kaihangao ngā takirere e rua:
- Ngā Takirere Venturi:ABC Flow Tech, Ngā Otinga Takirere o Shanghai.
- Ngā Takirere Pūrerehua:Zhejiang Danfoss Valve, Haina Yuanda Valve Group,Kaihanga Takirere o NSW
Ripanga Whakarāpopototanga Whakataurite
| Āhuatanga | Takirere Venturi | Takirere Pūrerehua |
| Hoahoa | Kāore he wāhanga neke, he korokoro whaiti | Kōpae hurihuri, tinana kiato |
| Te tika | Teitei | Waenga |
| Utu | Te utu tīmatanga teitei ake | Te utu tīmatanga iti iho |
| Te tiaki | Iti rawa | Ngā tirotiro hiri/kōpae ā-wā |
| Pai rawa atu mō | Te whakahaere rere tika | Whakaweto tere, paipa nui |
Whakamutunga
Ngā takirere Venturihe tino tika, he iti hoki te tiaki, engaringā takirere pūrerehuatuku utu whaitake me te tere o te whakahaere. I te wā e whiriwhiri ana, whakaarohia ngā whakaritenga rere, te tahua, me te wāhi. Mō te whakataetaengā utu, tūhurangā kaihanga i Hainahe tohunga ki ngā takirere ahumahi.
