He aha te Takirere: He Aratohu Momo me te Paerewa Tino Pai.

Tirohanga Whānui mō te Takirere Tirotiro

He takirere aunoa te takirere tirotiro e whakamahi ana i te pēhanga wai me te taumaha kōpae hei ārai i te rere whakamuri. E mōhiotia ana hoki ko te takirere kore-hoki, kotahi-ara, reflux, wehewehe rānei, ko tana mahi matua ko te whakarite i te rere kotahi-aronga hei tiaki i ngā pūnaha paipa mai i te kino o te rere whakamuri.

Te Mahi a ngā Takirere Tirotiro

Rere whakamuaKa hiki ake te kōpae i te pēhanga wai, ka taea ai te haere.

Rere whakamuriKa kati te kōpae mā te kaha ā-papa/pēhanga wai, ka aukati i te pāpāho.

Ngā Wāhanga Matua o ngā Takirere Tirotiro

Ko ngā wāhanga matua ko:

Tinana Takirere: Te anga o waho e hono ana i ngā paipa

KōpaeWaehere pūkoro e āhei ana ki te whakahaere rere

Nohoanga: Ka hanga i te mata hiri ki te kōpae

Koanga: Ka akiaki i te katinga o te kōpae (i roto i ngā momo āwhina-puna)

Tohu Takirere i roto i te Kauwhata PID

Te Mārama ki te Tohu Takirere

1.Porowhita: E tohu ana i te tinana takirere.

2.Pere, Rārangi Whakarara rānei: E tohu ana i te ahunga o te rere. He mea nui tēnei mō te tāutanga, kia tika ai te whakanoho o te takirere ki roto i te pūnaha.

3.Ngā Tuhipoka TāpiriI ētahi wā, ka tāpirihia pea ētahi atu tohu, tapanga rānei ki te tohu hei whakarato atu i ētahi atu kōrero, pēnei i te rahi o te takirere, te rauemi, te whakatauranga pēhanga rānei.

Ngā Paerewa Hoahoa Takirere

Ka kapi i ngā whakaritenga ngā paerewa ā-motu, ā-ahumahi, me te ao whānui mō ngā rauemi, te hanga, te mahi, me te tāutanga:

Ngā Painga o te Takirere Tirotiro

Ngā Painga Hoahoa me te Whakahaere

Te whakaoho-ā-ia-koeKāore he mana o waho e hiahiatia ana (kaha ā-papa/puna/whakahaerehia e te wai)

Te urupare tere: ≤0.05s te katinga (ngā takirere korehau) ka ārai i te poke o te rerenga whakamuri

Ngā hoahoa maha-whakamahinga:

• Momo hiki: Hiri pai rawa atu mō ngā pāpāho ma te P-teitei
• Momo piu: He iti te ātete mō ngā paipa kei roto he matūriki

Te Mahi me te Haumaru

• Ārai i te rere whakamuri o ngā pāpāho irahiko/waikura (ngā tipu karihi/matū)

• Ka whakaiti i te kino o te hama wai mā roto i ngā tikanga kati tere

• Ka mau tonu te pumau o te korehau (10⁻⁶~10⁻⁸ Pa·m³/s turuturu)

Ōhanga me te Hototahi

• He penapena hiko: Kore rawa he whakapaunga hiko tonu

• He whānuitanga rauemi: Kowiri tira/uku/rapa fluoro (-200°C~800°C)

• Whakamahinga maha-ahumahi: Pūnaha wai/hinu/hau/HVAC/matū
