A pūwhakaoho hau(e kiia ana hoki ko te *pneumatic cylinder* *air actuator* rānei) he taputapu nui i roto i te automation ahumahi. Ka hurihia e ia te pūngao hau kōpeke hei nekehanga miihini heiwhakatuwhera, kati, whakatikatika rānei i ngā takirere, e āhei ai te whakahaere tika i te rere o te wai i roto i ngā paipa. E mōhiotia ana mō te pono, te tere, me ngā āheinga ātete-pahū, e whakamahia whānuitia ana ngā kaiwhakaoho hau i roto i ngā tipu hiko, te tukatuka matū, ngā whare whakapai hinu, me ētahi atu.
Me pēhea te mahi a ngā kaiwhakaoho hau
Ka whakawhirinaki ngā pūkaha hau ki te hau kōpeke hei akiaki i ngā piston, i ngā diaphragm rānei, ka puta he nekehanga rārangi, he nekehanga hurihuri rānei. Ina piki ake te pēhanga hau, ka panaia e te kaha te piston, te diaphragm rānei, ka hangaia he nekehanga e whakahaere ana i ngā takirere hono. Mā tēnei tikanga ka taea te tere o te urupare me te putanga taipana teitei, ka pai ai mō ngā taiao ahumahi uaua.
Ngā momo Whakaoho Hau
Ka whakarōpūtia ngā pūkaha hau e te momo nekehanga, te hanganga, me te aratau mahi. Kei raro nei ngā momo matua, tae atu kihokinga mai o te kōanga, mahi takirua, meNgā kaiwhakaoho hau Scotch Yoke:
1. Mā te Momo Nekehanga
- Ngā Kaiwhakaoho RainaWhakaputa i te nekehanga rārangi-tika (hei tauira, ngā tokotoko pana-tō mō ngā takirere kuaha).
- Ngā Āhuatanga Koki/Hurihuri: Whakaputa nekehanga hurihuri (hei tauira, pōro huri-hauwhā, takirere pūrerehua rānei).
2. Mā te Hoahoa Hanganga
- Ngā Kaiwhakaoho DiaphragmWhakamahia te pēhanga hau hei piko i te diaphragm, he mea tino pai mō ngā mahi iti te kaha, teitei te tika.
- Ngā Whakaoho PistonWhakaputahia he pana teitei mō ngā takirere nui, ngā pūnaha pēhanga teitei rānei.
- Ngā Whakaoho Whatanga-me-PinionaTahurihia te nekehanga rārangi ki te hurihanga kia tika ai te whakahaere o te takirere.
- Ngā Whakaoho Hau Scotch YokeWhakamahia he tikanga ioka reti mō te taipana teitei i roto i ngā mahi taumaha (hei tauira, ngā takirere pōro nui).
3. Mā te Aratau Whakahaere
Pūwhakaoho Hau Whakahoki Puna (Mahi-Kotahi):
– Ka whakamahia te hau kōpeke hei neke i te piston i te wā eka whakaratohia e te puna te tautuhi aunoaina motuhia te tuku hau.
– E rua ngā momo: *Tuwhera Noa* (ka kati ki te hau, ka tuwhera ki waho) me *Ka kati Noa* (ka tuwhera ki te hau, ka kati ki waho).
– He pai mō ngā tono haumaru-kore e hiahia ana kia whakahokia mai te tūranga takirere i te wā e ngaro ana te mana.
Pūwhakaoho Haumātika Mahi-Rua:
– Me whai hau ki ngā taha e rua o te piston mō te nekehanga e rua ngā taha.
– Kāore he pūnaha puna; he mea tino pai mō ngā mahi tonu e hiahia ana kia hurihia pinepinetia te takirere.
– He nui ake te kaha e tukuna ana ki ngā tauira whakahoki-puna.
Ngā Whakamahinga Matua o ngā Pūwhakaoho Hau
He tino pai ngā pūkaha hau i roto i ngā ahumahi e hiahia ana ki te haumaru, te tere, me te pakari. Kei raro nei ngā whakamahinga matua:
1. Ngā Whakaritenga Whakatere-TeiteiTe whakakaha i ngā takirere nui i roto i ngā paipa, i ngā pūnaha pēhanga rānei.
2. Ngā Taiao MoreareaTe mahi ātete-pahū i roto i ngā whare hanga hinu, ngā tipu matū, te keri maina rānei.
3. Mana Tere o te TakirereNgā pūnaha urupare tere mō ngā whakaweto ohorere, ngā whakarerekētanga rere rānei.
4. Ngā Āhuatanga KinoHe mahi pono i roto i ngā pāmahana tino kino, te haumākū, ngā tautuhinga waikura rānei.
5. Ngā Pūnaha AunoatangaTe whakaurunga ki ngā PLC mō te whakahaere tukanga maeneene.
6. Whakawhiti Ā-ringa/AunoaHe wira ā-ringa kua hangaia hei huri ā-ringa i ngā wā e raru ana te pūnaha.
He aha i whiriwhiri ai i ngā kaiwhakaoho hau
- Whakautu TereTauhohenga tonu ki ngā tohu whakahaere.
- Te Pono TeiteiHe iti noa te tiaki, he pakari te hanganga.
- Haumaru PahūtangaKāore he mura hiko, he pai mō ngā taiao mura.
- Whai hua te utuHe iti ake ngā utu tīmatanga me ngā utu whakahaere ki te whakataurite ki ngā momo hiko waipēhi/hiko kē atu.
Whakamutunga
Te māramatangahe aha te mea he pūkaha haume te whiriwhiri i te momo tika—ahakoa hepūkaha hau whakahoki puna, pūwhakaoho mahi-rua, rāneiPūwhakaoho hau Scotch Yoke—ka whakarite i te mahi tino pai i roto i ngā pūnaha ahumahi. Mā te whakataurite i te hoahoa o te actuator (rārangi, hurihuri, diaphragm, piston rānei) ki ō hiahia whakahaere, ka whakarei ake koe i te whai huatanga, te haumaru, me te roa o te ora i roto i ngā tono whakahaere wai.
Mō ngā ahumahi e whakatairanga ana i te tika, te roa, me te haumaru, ko ngā kaiwhakaoho hau tonu te otinga matua mō te aunoatanga o te takirere.
