1. Te Mātāpono Mahi me ngā Tikanga Puku Whakaoho
A takirere pōro hauhautangahetakirere pōro huri-hauwhātinana
i honoa ki tētahipūwhakaoho hauKa hurihia e te actuator te hau tipu kua kōpeketia (te tikanga
4.0–8.0 pae / 60–115 PSI) ki roto i te taipana miihini, e akiaki ana i te kakau takirere me te pōro mā te hurihanga 90°
hei whakatuwhera, hei kati rānei i te ara rere tere.
1.1 Ngā Momo Pūwhakaoho Hau
- Ngā Whakaoho Rack & Pinion: He piston takirua ātete me ngā whata taputapu e hono ana ki te pinion pokapū.
Ko ngā painga ko te tapuwae kiato, te putanga taipana rārangi, te pai o te mahi ā-mīhini, me te urupare tere.
He tino pai mō ngā takirere poka iti-ki-waenga (½” ki te 12″). - Ngā Whakaoho Scotch YokeWhakamahia he tikanga ioka e whakaputa ana i tētahi kōpiko taipana kore-rārangi—
te tuku i te taipana mōrahi i ngā tūranga whakatuwheratanga me ngā tūranga hiri nohoanga.
Nā tēnei ka waiho rātou hei kōwhiringa tino pai mōngā takirere pōro e mau ana i te trunnion nui
(DN150 ki te DN600+ / Akomanga 150 ki te Akomanga 2500).
1.2 Mahi Takirua vs. Hokinga-Koanga (Mahi Takitahi)
Mā te whiriwhiri i te aratau mahi a te kaiwhakaoho tika ka pā tika ki te haumaru o te tukanga i te wā e pakaru ana te tuku hau:
| Mahi Whakaoho | Te Mahi Tuku Hau | Tūnga Haumaru-Hē (Ngaronga o te Hau) |
|---|---|---|
| Mahi-Taurua (DA) | Ka tuwhera te hau ki te tauranga A; ka kati te hau ki te tauranga B | Kāore i te Tūnga: Kei te pupuri te takirere i te tūranga whakamutunga |
| Te Hokinga Mai o te Kōanga (SR) | Ka pēhia ngā puna e te pēhanga hau mō te kotahi whiu; ka whakahokia mai te kaha o te puna | Haumaru-Hē Ā-Mīhini: Kati-Hē Aunoa (FC) Tuwhera-Hē rānei (FO) |
He mea whakahau kia whakamahia ngā pūkaha whakahoki-puna hei whakarite i te tūnga aunoa o te takirere ki tētahi āhua haumaru ina ngaro te hau o te taputapu, te mana tipu rānei.
2. Hanganga Tinana Takirere me te Nohoanga Mahi-Teitei
Ko te pono mō te wā roa o te takirere pōro hau e whakawhirinaki ana ehara i te mea ko te actuator anake engari ko te
te hoahoa o te tinana takirere me te whiriwhiri rauemi nohoanga. Whakaarohia te pāmahana whakahaere, te pēhanga,
te waikura, me te nui o ngā matūriki i te wā e whiriwhiri ana i ngā rauemi.
2.1 Ngā Whirihoranga o te Tinana o te Takirere
- Hoahoa Pōro MānuHe pai mō ngā tono DN15–DN100, Akomanga 150–300.
Ka panaia te pōro e te pēhanga o runga ki te nohoanga o raro hei hiri. He māmā, he iti hoki te utu. - Hoahoa Pōro e Mau ana ki te TrunnionE hiahiatia ana mō ngā ratonga pēhanga-teitei/pūnga-nui DN50–DN600, Akomanga 150–2500.
Ka herea te pōro e te kakau o runga me te peera trunnion o raro, ka whakaiti i te taipana whakahaere tae atu ki te 50%.
me te tiaki i ngā mata hiri—he mea tino pai mō te pahikara aunoa auau. - Te Tākai Utaina Ora: Ka mau tonu te takai karāhe ngāwari whakakaha-puna o Belleville

2.2 Whakataurite i ngā Rauemi Nohoanga
| Momo Nohoanga | Ngā Rauemi Noa | Awhe Pāmahana me ngā Āhuatanga |
|---|---|---|
| Nohoanga Ngāwari | PTFE / RPTFE / PEEK / PPL | −29°C ki te 260°C (TIRO ki te 300°C) ANSI/FCI 70-2 Akomanga VI kati-pupuhi |
| Nohoanga-Metara (Panitia ki te HVOF) | Kāpiro Tungsten / Kāpiro Chrome (HRC 68–72) | −196°C ki te 650°C Kohu pāmahana teitei, paru, matūriki whakakorikori, rauemi whakakoi |
Mō ngā āhuatanga ratonga kino e pā ana ki ngā pāmahana teitei, te pēhanga rerekētanga teitei, ngā pāpāho kī tonu i ngā totoka rānei,
ngā takirere pōro trunnion e nohoia ana e te whakarewame ngā paninga rehu wera HVOF e tino taunakitia ana.
3. Ngā Taputapu Pūnaha Whakaweto me te Whakahaere ohorere a te ESDV
I roto i ngā ahumahi matū hinu, tuku hau, me te whakaputa hiko, he maha ngā wā ka whakamahia ngā takirere pōro hau
kua tohua heiESDV (Ngā Takirere Whakamutu Āwhati)EIV rānei (Ngā Takirere Wehewehe Ohorere).
Koinei ngā wāhanga whakahaere whakamutunga i roto iNgā Pūnaha Taputapu Haumaru (SIS), kei hea
Ka pā tika te tere me te pono o te urupare ki te haumaru o te tipu.
Mōkihi Taputapu ESDV Noa mō ngā Takirere Pōro Hau
- Ngā Takirere SolenoidAtanga NAMUR, ara 3/2, ara 5/2 rānei, kua whakamanahia e SIL 2/3 mō te hononga hiko-hau.

me tohu kia iti ai te wā e pau ai te pūhiko.
4. Ngā Paerewa Hoahoa me te Tatau Rahi Taipana Whakaoho
Ko te taahiraa tino nui i roto i te whiriwhiri i te pūkaha haute whakataurite i te taipana.
Mā te iti o te rahi ka mutu te katinga o te takirere, ka kore rānei e oti te kati; mā te rahi rawa ka nui ake te utu, te tapuwae,
ā, ka nui rawa te taumahatanga e pā ki te tinana o te takirere.
