Te Whakarerekētanga o ngā Takirere Pōro mō ngā Wāhi Morearea

Kupu Whakataki

Ngā Takirere Pōroe whakamahia whānuitia ana puta noa i ngā pūnaha ahumahi nā te mea he pono, he tere te mahi, he pakari hoki te mahi whakaweto. Heoi, ina tāutahia ki rotongā wāhi morearea—pērā i ngā whare hinu me te hau, ngā whare matū, ngā whare whakapai hinu, me ngā mahi keri—kāore i te rawaka ngā hoahoa takirere paerewa.

Ka puta mai ngā mōrearea i roto i ngā taiao morearea tae atu ki ngā hau mura, te puehu mura, te pāmahana tino kino, ngā mea waikura, me ngā pūtake mura pea. Hei whakahaere haumaru, pono hoki i raro i ēnei āhuatanga,Ngā Takirere Pōrome hanga motuhake, me whakamana, me whakamatautauria hokimō te ratonga tauwāhi morearea.

E whakamārama ana tēnei tuhingame pēhea te whakarerekētanga o ngā takirere pōro mō ngā wāhi morearea, e arotahi ana ki ngā whakarerekētanga hoahoa, te kōwhiringa rauemi, ngā tiwhikete, me ngā aratohu kōwhiringa mahi mō ngā kaiwhakamahi ahumahi.

ngā whakarerekētanga, te kōwhiringa rauemi, ngā tiwhikete, me ngā aratohu kōwhiringa mahi mō ngā kaiwhakamahi ahumahi.

He aha te wāhi e kiia ana he mōrearea?

Ko te wāhi morearea e tautuhia ana ko tētahi wāhi kei reirangā hau mura, ngā kohu, ngā wai, ngā puehu mura rāneitērā pea kei roto i ngā rahinga e ranea ana hei hanga i te mōrearea o te ahi, o te pahūtanga rānei.

Ko ngā pūnaha whakarōpūtanga noa ko:

• Ngā Rohe IEC / ATEX

  • Rohe 0 / 20: Te noho tonu mai o te hau pahū

  • Rohe 1 / 21: Te tūponotanga o te kitea i te wā e mahi noa ana

  • Rohe 2 / 22: Kāore e tūpono, he wā poto noa iho

• Ngā Akomanga me ngā Wāhanga NEC / CEC

  • Akomanga I: Ngā hau me ngā kohu

  • Akomanga II: Puehu mura

  • Akomanga III: Ngā muka me ngā rerenga

Me tutuki ngā takirere pōro e whakamahia ana i ēnei taiao ki ngā whakaritenga whakarōpūtanga me ngā whakaritenga ture e tika ana.

Ngā Urutaunga Hoahoa Matua mō ngā Takirere Pōro Wāhi Morearea

1. Hoahoa Ārai-Patū (Tukunga Hiko Patū)

I roto i ngā āhuarangi morearea, ka taea e te hiko pateko te mahi hei pūtake mura. Hei whakaiti i tēnei mōrearea, ka whakauruhia ngā takirere pōro mahi moreareangā taputapu ārai-pūmaue whakarite ana i te haere tonu o te hiko i waenga i:

• Pōro me te kakau

• Te kakau me te tinana

Ka ārai tēnei i te kohikohinga utu pateko i te wā e mahi ana te takirere, inā koa i ngā tono hau rere nui, hau maroke rānei.

2. Hanganga Haumaru-Ahi

Kua hangaia ngā takirere pōro haumaru-ahi hei pupuri i te pono o te hiriahakoa i muri i te pānga ki te ahi.

Ko ngā āhuatanga noa ko:

• Te hiri tuarua whakarewa-ki-whakarewa

• He tākai kakau ātete-ahi, he tākai karāhe rānei

• Te whakatutuki i ngā paerewa pērā i teAPI 607, API 6FA, ISO 10497 rānei

He mea tino nui te hoahoa haumaru-ahi i roto i ngā mahi hinu me te hau, te matū-petrochemical, me te wheketere whakapai.

3. Ārai-Pahūtanga me te Whakaoho-Mōrearea

Ina aunoatia ngā takirere pōro, ka noho te actuator hei wāhanga haumaru tino nui.

Tērā pea ka rite ngā takirere pōro mō ngā wāhi morearea ki:

• Ngā pūkaha hiko ātete-pahū

• Ngā kaiwhakaoho hau me ngā solenoid kua whakamanahia

• Ngā āpitihanga kua whakatauria kiATEX, IECEx, UL, CSA rānei

Kua hangaia ēnei pūwhakaoho hei aukati i te horapa o te mura o roto ki te taiao o waho.

4. Te Whakapai Ake i te Hiri me te Whakahaere Tukunga Rerenga

Ka puta he mōrearea mō te haumaru me te taiao i te turuturu o ngā mea kino. Ka whakamahia e ngā takirere pōro kua whakarerekētia:

• Te tākai kakau iti-tukunga (ngā pūnaha e hangai ana ki te karāpiti, ki te PTFE rānei)

• Ngā whakaritenga tākai ora

• Te whakatutuki i ngā whakaritengaISO 15848 or API 622

Mā tēnei ka roa te mahi hiri i raro i te pēhanga, te wiri, me te huringa pāmahana.

5. Ngā Rauemi Pakari mō ngā Āhuatanga Kino

He mea nui te whiriwhiri rauemi i roto i ngā taiao morearea.

Ko ngā urutaunga noa ko:

• Ngā tinana kowiri tira, takirua, takirua rānei

• Ngā koranu ātete-waikura (Inconel, Monel, Hastelloy)

• Ngā paninga ārai-waikura mō te tiakitanga o waho

• Ngā nohoanga me ngā hiri kua whakaroahia te pāmahana

Ka whakarei ake ēnei rauemi i te roa o te mahi i roto i te waikura, te pēhanga teitei, te pāmahana tino kino rānei.

Ngā Whakamahinga Noa o ngā Takirere Pōro Wāhi Morearea

Ko ngā takirere pōro kua whakaritea mō ngā wāhi morearea e whakamahia whānuitia ana i roto i:

• Ngā pūnaha hinu me te hau i runga, i waenganui, me raro

• Ngā whare tukatuka matū me te hinu

• Ngā whare whakahaere LNG me te LPG

• Ngā papaaho o waho

• Te keri me te whakahaere rauemi papatipu

• Te hanga peita, whakarewa, me te rongoā

I roto i ēnei whakamahinga, ka taea e te rahunga o te takirere te hua ake i ngā aituā haumaru nui, nā reira he mea nui te whakatakotoranga tika o te takirere.

Me pēhea te whiriwhiri i te takirere pōro tika mō ngā wāhi mōrearea

I te wā e whiriwhiri ana i tētahi takirere pōro mō ngā mahi mōrearea, whakaarohia ngā āhuatanga e whai ake nei:

Ngā Tikanga Whakahaere

• Awhe pēhanga me te pāmahana

• Momo pāpāho (hau, wai, paru)

• Te aroaro o ngā matū waikura, ngā mea whakakoi rānei

Te Whakarōpūtanga Tūponotanga

• Ngā whakaritenga mō te Rohe / te Akomanga / te Wehenga

• Ngā tiwhikete e hiahiatia ana (ATEX, IECEx, UL, me ētahi atu)

Whirihoranga Takirere

• He hoahoa e mānu ana, e mau ana rānei i te trunnion

• Ngā whakaritenga haumaru mō te ahi me te ārai-pūmau

• NACE MR0175 / ISO 15156(Ratonga kawa)

Me manatoko tonu te whānuitanga o te tiwhikete me te ōritetanga mō te tono motuhake.

Ngā Pātai Auau (FAQ)

He pai ngā takirere pōro paerewa mō ngā wāhi morearea?

Kāo. Ko ngā takirere pōro paerewa kāore i te nuinga o te wā he hoahoa ārai-pūmau, he hanganga haumaru-ahi, ā, he mea whaimana hoki mō ngā taiao morearea.

Me whai taputapu ārai-pahū ngā takirere pōro katoa mō ngā wāhi morearea?

Ko ngā takirere aunoa anake e hiahia ana ki ngā pūkaha ātete-pahū, ātete-morearea rānei. Me whai tonu ngā takirere ā-ringa i ngā āhuatanga ārai-pūmau me te haumaru-ahi.

He aha te rerekētanga i waenga i te tiwhikete ATEX me te IECEx?

He aratohu a Ūropi a ATEX, ko IECEx ia he kaupapa tiwhikete ā-ao. E aro ana ēnei e rua ki te haumaru o ngā taputapu i roto i ngā hau pahū, engari ko te whakaaetanga kei runga i ngā ture ā-rohe.

Kia pēhea te auau o te tirotiro i ngā takirere tūnga morearea?

Ko te auau o ngā tirotiro ka whakawhirinaki ki te kaha o te ratonga, engari me tirotiro me te tiaki auau kia mau tonu ai te tutuki i ngā whakaritenga me te haumaru.

Whakamutunga

Me whakamahi ngā takirere pōro i ngā wāhi moreareahoahoa motuhake, ngā wāhanga whaimana, me te tutuki pūmau ki ngā paerewa o te aoMā te whakauru i ngā āhuatanga ārai-pūmau, te hanganga haumaru-ahi, te whakaoho ātete-pahū, me ngā rauemi pakari, ka taea e ēnei takirere te mahi haumaru i roto i ētahi o ngā taiao ahumahi tino uaua.

Mō ngā kaihangarau, ngā kaihoko EPC, me ngā tohunga hokohoko, he mea nui te mārama ki te whakarerekētanga o ngā takirere pōro mō ngā wāhi morearea hei whiriwhiri i ngā takirere whai whakaaro, whai ture, me te whai hua.
