He aratohu hangarau whānui mōNgā Takirere Pūrerehua Hauātea—e hipoki ana i ngā tikanga taraiwa o te actuator,ngā hoahoa taurite, te tatau taipana, te whakairinga ISO 5211, me ngā paerewa API 609 mō te aunoatanga ahumahi.
Whakarāpopototanga Matua: He aha te takirere pūrerehua e whakaohohia ana e te hau?
1. Te Mātāpono Mahi me te Hangarau Whakaoho Hau
He aunoatakirere pūrerehua hauka huri i te pēhanga hau (te nuinga o te wā 4.0–8.0 paete tuku hau tipu) ki roto i te hurihanga o te pou miihini. Ka mahi te hau kōpeke ki ngā piston o roto, ki ngā diaphragm rāneii roto i te whare actuator, e akiaki ana i tētahi rakau hurihuri 90° e hono ana ki te kōpae takirere mā te
ISO 5211atanga flange o runga.
Ngā Momo Pūnaha Puku Whakaoho Takirere Pūrerehua
Te whiriwhiri i te mea tikapūwhakaoho takirere pūrerehuaka whakawhirinaki ki te pihi putanga taipana, te auau huringa, me te rahi o te poka takirere:
- Ngā Whakaoho Rack me Pinion:Ka tukuna e ngā piston takirua me ngā whata taputapu whakauru he raina rainate taipana puta noa i te whiu 90° katoa. Ko te tapuwae kiato me te huringa tere e hanga ana i a rātou hei umangate paerewa mō ngā takirere aunoa poka māmā-ki-waenga (DN40 ki DN300).
- Ngā Whakaoho Scotch Yoke:Ka whakaputahia he taipana kore-raina e te huihuinga pine-me-poraka iokakōtaha me te putanga mōrahi i ngā pito whiu (te pakaru me te nohoanga). Mā tēnei painga ā-mīhini ka putahe pai mō ngā mea he whānui te whānui, he mahi teitei, he mea whakanoho rānei ki te mea whakarewatakirere pūrerehua taurite-toru
(DN350 ki te DN1200+).
Ngā Aratau Mahi Hauātea: Mahi Takirua vs. Whakahokinga o te Puna
| Whirihoranga Kaiwhakaoho | Tikanga Whakahaere | Tūnga Mahi Haumaru-Rahua |
|---|---|---|
| Mahi Takirua (DA) | Me whai hau kōpeke i te Putanga A hei whakatuwheratanga, me te Putanga B hei kati. | Te korenga i te tūranga:Ka mau tonu ki tōna tūranga o nāianei ina ngaro te hau e tukuna ana. |
| Te Hokinga Mai o te Koanga (SR / Mahi Takitahi) | Ka pehia e te pēhanga hau te taha kotahi, ā, ka pēhia ngā puna o roto. Ka pehia e ngā puna te taha kē. | Haumaru-Hē Mīhini:Ka whakawhiti aunoa kiKati-Rahua (FC) or Tuwhera-Rahua (FO)i te korenga o te hau. |
Te Tirohanga Matua mō te Hangarau
Mō ngā tono haumaru nui (hei tauira, ngā pūnaha whakaweto ohorere), tohua tonutiangā kaiwhakaoho hokinga mai o te puname te tūranga haumaru-kore e tika ana. He pai ake ngā kaiwhakaoho mahi takirua mō te whakarerekē i te mana whakahaere inahe mea whakaaetia te pupuri i tōna tūranga i te wā e ngaro ana te mana.
2. Te Hanganga o te Tinana Takirere me ngā Momo Hoahoa Āpitihanga
Ko te rerekētanga ā-pūkaha o te rakau kōpae e whakatau ana i te taipana whakahaere, te waku nohoanga, me ngā āheinga wera.o tētahitakirere pūrerehua momo actuator:
1. Ngā Takirere Pūrerehua Porowhita (Noho Ātete)
Kei waenganui o te kōpae me te kōhao nohoanga te kakau. Ka whakamahia he raina elastomeric ngohengohe (EPDM, NBR,Viton, PTFE rānei) hei whakatutukiWhakaweto kore-tauraki ANSI/FCI 70-2 Akomanga VI. Tino pai rawa atumō ngā ratonga wai pēhanga iti, hau, HVAC, me ngā matū ngawari tae atu ki te 16 pae me te 150°C.
2. Ngā Takirere Pūrerehua Āpitihanga Takirua (Mahinga-Teitei)
Te rerekētanga o te pou mai i te pokapū nohoanga me te pokapū poka paipa. Nā tēnei āhua rerekē rua ka puta te kōpaehei "hiki" i te nohoanga i te wā e hurihuri ana, hei whakaiti i te waku, hei whakaheke i te taipana nohoanga, hei whakaroa hoki i te nohoangate roa o te ratonga. Kei te wātea me ngā nohoanga ngohengohe PTFE/RPTFE, ngā mowhiti hiri whakarewa ngāwari rānei mō te pēhanga-waenga
ngā raina mamaoa me ngā raina tukatuka.
3. Ngā Takirere Pūrerehua Noho-Metara Toru (TOBV)
He koki āwhata tuatoru kei roto i te āhua o te kōne nohoanga. Ko tēnei kāme-mahi, kāore e mirimirika tutuki i te hoahoa te hurihuri kore-waku me te nohoanga whakarewa-ki-whakarewa piri (Stellite / Laminated StainlessRino). I hangaia mō te mahi kaha, ngā pāmahana teitei tae atu ki te 550°C+, ngā wai cryogenic, ā, he haumaru ki te ahi.ngā mahi whakahaere.
Ngā Kōwhiringa Whakamutu Hononga
- Momo Angaanga:He tinana kiato e puritia ana i waenga i ngā parirau paipa mā roto i ngā pūtu. He iti rawa te taumaha me te tapuwae.
- Momo Pūkoro:He miro ngā hononga i runga i te tinana e rite ana ki ngā tauira pūtu o te flange. Ka taea te mahi i te mutunga kore me te tiaki i te raina hiko i raro iho.
- Momo Taparua:He flange whakauru ki ngā pito e rua; me mātua whakamahi mō ngā diameter nui (DN300+) me ngā tāutanga paipa tanumia, taumaha rānei.
3. Ngā Taputapu Porowhita Whakahaere Aunoa
Hei huri i tētahi takirere pūrerehua hau paerewa hei wāhanga whakahaere whakamutunga atamai, he huingao ngā taputapu hau e whakairihia tika ana mā teNāmurmeISO 5211ngā atanga:

5. Ngā Pātai Auau (Ngā Pātai Auau mō te Hangarau)
Q1: Ka taea te whakamahi i te takirere pūrerehua hau hei whakahaere i te rere o te hau?
Āe. Mā te whakauru i tētahi takirere pūrerehua takirua, takirua rānei, ki tētahi tūnga hiko-hau matihiko.(tohu 4–20mA), ka mahi te huihuinga hei takirere whakahaere whakarerekētanga whai hua mō te rere-teitei, te pēhanga-itingā paipa maturuturu.
Q2: He aha te painga matua o te takirere pūrerehua momo actuator i te takirere pōro?
He mama ake ngā takirere pūrerehua hau, he kiato ake ngā rahi mata ki te mata, ā, he nui akehe iti ake te utu mō ngā raina rahi nui (DN200 / 8-inihi me runga ake) ki te whakaritea ki ngā takirere pōro rahi ōrite.
P3: He aha te hiranga o te paerewa whakairinga ISO 5211 mō te kaiwhakaoho takirere pūrerehua?
Ka tautuhia e te ISO 5211 ngā tauira pūtu ōrite, ngā ine o te rakau taraiwa, me ngā ine o te flange. Mā tēnei ka whakarite kia paerewahiate whakawhitiwhiti, e āhei ai ngā kaiwhakaoho hau mai i ngā kaihanga rerekē ki te whakairi tika ki runga i ngā kakau takirerekāore he taiapa ritenga.
Q4: He aha te rerekētanga i waenga i ngā takirere pūrerehua nohoanga-ngāwari me ngā takirere pūrerehua nohoanga-whakarewa?
Ka whakamahia e ngā takirere ngohengohe ngā nohoanga elastomeric, PTFE rānei hei whakaweto i te kore turuturu i ngā pāmahana iti iho.(te tikanga ≤150°C). Ka whakamahia e ngā takirere e nohoia ana e te konganuku (takitoru te rerekētanga) te hiri konganuku-ki-konganuku, ā, ka taea te tu atutae atu ki te 550°C+, e pai ai mō te mamaoa, te hinu wera, me ngā mahi cryogenic.
