He aha te takirere pōro mānu?
A takirere pōro mānuko tētahi o ngā momongā takirere pōro, ā, ko te mea e rite ana kotakirere pōro e mau ana i te trunnion. Kei roto i tēnei he pōro kāore he tautoko e puritia ana i waenganui i ngā nohoanga hiri e rua anake. Ka hono ngāwari te kakau ki te pōro, ka taea ai e ia te "mānu." I raro i te pēhanga reo, ka neke te pōro ki te nohoanga o raro, ka hanga he hiri piri ki te taha putanga.

Ngā Āhuatanga Hanganga Hangaia o te Takirere Pōro Rere
1. Hoahoa Nohoanga Hiri-Rua
Ka whakaitihia te taipana whakahaere e te mīhini nohoanga iti-waku motuhake, me te whakarite hoki i te mahi kore-tauraki mā te hiri rua-ahu.
2. Kākano Ārai-Whakataurite
Mā te kakau papatahi e ārai te kore tika o te tūnga o te kakau. Kakau whakarara = Tuwhera; Kakau poutū = Kati.
3. Ngā Pūaha Maukati Haumaru
Mā ngā kōhao raka takirua i ngā tūranga tuwhera/kati katoa ka ārai i te tūponotanga—he mea nui mō ngā paipa morearea.
4. Kākano Ārai-Pahū
Ka ārai te pakihiwi whakauru i te pekenga o te kakau i te wā e pēhia nui ana, kia mau tonu ai te pumau o te hiri.
5. Pūnaha Ārai-Patu
Ka tukuna e ngā puna whenua te hiko pateko e puta mai ana i te waku—he mea nui mō ngā mea mura pēnei i te LNG, te propane rānei.
6. Hanganga Haumaru-Ahi
Ka hono ngā hiri tārua whakarewa-ki-whakarewa i ngā wā ahi:
• Ka whakakapia ngā nohoanga kua wera e te pā o te pōro/tinana
• Ka whakawhanuihia ngā hiri ahi karāhe hei ārai i ngā turuturu
•API 607/6FA e tutuki ana
7. Hononga Tinana Kore-Tae
Mā te hoahoa hononga o te flange ka kore e whakawhirinaki ki te gasket, ka ārai i te turuturu o waho i raro i ngā āhuatanga tino kino.
Ngā Taupānga Ahumahi
• Ratonga Whānui: Wai, whakarewa, waikawa
• Pāpāho Hiranga: Hāora, H₂O₂, methane
• Ngā Taiao Kino:
Ngā whare hanga hinu matū
Ngā paipa hau māori (ātete ki te H₂S)
Ngā pūnaha cryogenic
Te kawe i te paru waikura-teitei
Ngā Painga me ngā Here o ngā Takirere Pōro Mānu
Ngā Painga:
✓ He hoahoa kiato, he ngāwari hoki te tiaki
✓ Hiri piri-mirumiru
✓ Ātete iti ki te rere
✓ Mahi tere 90°
Ngā Huakore:
✘ Ka whakawhāitihia e te waku nohoanga te whakamahinga nui-P/T
✘ Kāore mō ngā paru (mōrearea te aukati i te awaawa)
✘ Me whai tāutanga matatau
Ngā Kawa Tāutanga me te Tiaki
Ngā Whakaritenga Tāutanga
• Whakamaua whakapae ki runga i ngā mata papatahi
• Āraia te rere o te wai e tata ana ki te pōro
• Kia kore he arai i te urunga
Rārangi Arowhai Tiaki
• Ia hauwhā: Tirohia ngā mowhiti pōro/waru mō te pirau
• Ia tau:
Whakahinuhinuhia ngā peera kakau
Manatokohia ngā uara taipana
Whakamātauria ngā hiri ohorere
• Whai muri i te whakaweto: Horoia te kōhao hei ārai i ngā putunga tioata
Mānu vs.Ngā Takirere Pōro e Mau ana ki te TrunnionWhakatairite Hangarau
| Āhuatanga | Momo Mānu | Momo Whakamau Trunnion |
|---|---|---|
| Te Kaupapa Hiri | Ka pana te pēhanga pāpāho i te pōro ki te nohoanga | Ka akiakihia ngā nohoanga e ngā puna ki te pōro |
| Te Whakamaunga | Kakau kotahi o runga | Tautokohia te trunnion takirua |
| Whakatauranga Pēhanga | ≤Akomanga 1500 (DN300 mōrahi) | Tae atu ki te Akomanga 2500 (DN1500+) |
| Ngā tono | Ngā pūnaha pēhanga iti-waenga | Ngā paipa matua (hei tauira, Kaupapa Hau Hauāuru-Rawhiti) |
Aratohu Kōwhiringa
Kōwhiria ngā takirere mānu mō ngā otinga iti, utu-pai hoki i raro i te Akomanga 600. Kōwhiria ngā takirere e mau ana ki te trunnion ina whakamahia ana:
• Ngā Pēhanga >Akomanga 900
• Ngā mahi pahikara auau
• Pāpāho waikura, pāpāho waikura rānei
