Ārai haumaru wehewehe whakauru pūoko mura me te pūoko paowa
Kupu Whakataki
He mea nui te haumaru me te ārai i te ahi i ngā wāhi katoa. He mea nui rawa atu ēnei i roto i ngā taiao morearea e ngāwari ana ki te ahi me te pahū. I tēnei wā, Haumaru ā-roto He tino painga ngā taputapu kite ahi me ngā ārai haumaru ā-roto. Kua hangaia ēnei pūnaha motuhake hei ārai i ngā ahi me ngā pahūtanga. Ka tutuki tēnei mā te whakaiti i te pūngao hiko me te pūngao wera i roto i te pūnaha taputapu kite.
Ngā kaupapa matua:
nHe mea nui ngā taputapu kite ahi haumaru i roto i ngā taiao morearea kei reira ngā hau pahū, ngā matū mura rānei.
nKa whakakorea rawatia e tēnei momo taputapu motuhake ngā tūponotanga mura mā te whakawhāiti rawa i te putanga o te pūngao whakamahana hiko.
nI roto i ngā mara morearea nui pēnei i te matū hinu, te hanga rongoā, me te rokiroki rauemi morearea, kāore e taea te whakakapi i tēnei hangarau.
nKo te mātau ki ngā āhuatanga me ngā horopaki e tika ana mō ngā momo pūoko haumaru ā-roto he mea nui ki te hanga i tētahi pūnaha ārai ahi tika.
nKo te mahi haumaru me te pumau o ngā taputapu kite kua whakamanahia e ngā whakahaere o te ao pēnei i Atex kua manatokohia mana.
Me pēhea te mahi a te pūoko ahi haumaru ā-roto?
nI ngā wāhi mura me ngā wāhi pahū pērā i te hinu me te hau, te matū, me te tukatuka witi, ka tūpono ngā taputapu kite ahi tuku iho ki te haumaru nā te mea ka puta he mura hiko, ka wera rawa rānei te mata, engari ka whakarite ngā taputapu kite haumaru ā-roto (IS) i te mahi haumaru i roto i ngā taiao morearea mā te hoahoa motuhake.
nKo tōna hangarau matua kei roto i te tikanga whakawhāiti pūngao: mā te whakahaere tika i te iahiko me te pūngao wera i roto i te ara iahiko, ka whakarite kia kore te taputapu e whakaputa i ngā mura mura, i ngā pāmahana tiketike morearea rānei i raro i ngā āhuatanga mahi katoa. Hei whakatutuki i tēnei whāinga, me whai ārai haumaru te pūnaha - he wāhanga nui kua tāutahia i waenganui i te kaiwhakahaere whakaoho me te taputapu IS, ka taea te aukati i te tuku pūngao nui rawa atu, me te pupuri i te mana ara iahiko i raro i te paepae haumaru i ngā wā katoa.
nMā tēnei hoahoa parenga rua (herenga pūngao ā-roto + ārai haumaru o waho) ka waiho te pūoko IS hei otinga aroturuki ahi pono rawa atu mō ngā wāhi morearea, me te tutuki anō hoki i ngā paerewa ā-ao ātete-pahūtanga pēnei i te ATEX.
Te tutuki me ngā paerewa o ngā pūoko ahi haumaru ā-roto i te UK
I te UK, he tino pakari ngā ture mō te whakamahinga o ngā taputapu haumaru ahi i ngā wāhi morearea. Ehara i te mea he whakaritenga ture anake te whai i ēnei ture, engari he mea nui anō hoki mō te whakarite i te haumaru o ngā kaimahi me te maeneene o ngā mahi.
Ko tētahi huinga ture matua ko te Ngā Ture a AtexI ahu mai ēnei ture i ngā aratohu a te EU e aro ana ki te whakarite i ngā paerewa haumaru mō ngā taputapu e whakamahia ana i ngā wāhi ka pā mai pea ngā pahūtanga.
He mea nui ngā ture ATEX mō te hunga e hanga ana, e hoko ana, e whakamahi ana rānei i ngā taputapu haumaru i ngā wāhi ka pā mai pea ngā pahūtanga. I ngā wāhi morearea i roto i te Kotahitanga o Ūropi (tae atu ki te UK), me tutuki ngā taputapu me ngā pūnaha tiaki katoa i ngā ture ATEX.
Paerewa | Whakaahuatanga |
Te Aratohu ATEX 2014/34/EU | Kei roto i tēnei ko ngā taputapu me ngā pūnaha tiaki e whakamahia ana i ngā wāhi ka pā mai pea ngā pahūtanga. |
IEC 60079 | He huinga ture ā-ao mō te hoahoa, te tāuta me te whakamahi haumaru i ngā taputapu hiko i ngā wāhi pahū. |
He mea nui te mārama me te piri ki ēnei ture. Mā tēnei ka āwhina i te whakarite i te haumaru ina whakamahia ngā taputapu kite ahi haumaru ā-roto i ngā wāhi morearea.
Kōwhiria ngā ārai haumaru ā-roto e tika ana
Ko mātou, ko Beijing Pinghe, he kaiwhakarato arai kounga teitei, he mahere whanaketanga tā mātou e aro ana ki te whakaiti i te rahi ā-tinana o ngā arai, kia māmā ai, kia ngāwari ai hoki te whakahaere, kia māmā ai te tāutanga, kia whakaitihia ai te mōrearea o te rahunga, me te whakarato i ngā arai e tino tika ana mō ngā pūnaha tukatuka.
Kua hangaia ā mātou PHD-11TN-11 me PHD-22TN-1111 mō te whakamahi me ngā pūoko paoa.
Ko te tohu whakauru o ngā pūoko mura me te paowa he arai haumaru motuhake, ka taea te whakarato mana wehe ki ngā pūoko mura i ngā wāhi morearea. Ka whakaputahia e ngā pūoko mura ngā tohu 0-40mA ka wehea mai i ngā wāhi morearea ka tukuna ki ngā wāhi haumaru, ka whai wāhi ki te whakaoho paowa. Ka whakakahangia tēnei hua e tētahi ara iahiko putanga, ā, he pai mō ngā pūnaha DCS/PLC e whakakahangia ana e te porowhita.
Kāore tēnei hua e hiahia ki tētahi pūtake hiko motuhake, ā, kua wehea ngā pito tāuru me ngā pito tāuru.
