Te Haumarutanga Kore-Whakataurite o te Hangarau: Te Parenga Pahūtanga i roto i ngā Pūhiko Diaphragm

I roto i ngā ahumahi e whakahaerehia ana ngā hau mura pēnei i te hauwai, te hau maori, ngā matū tukatuka rānei, ka hipa ake te haumaru mahi i te hanganga ture—ka noho hei whakaritenga matatika.Ngā pūwero diaphragmte aro atu ki tēnei wero mā roto i ngā mātāpono hangarau haumaru ā-roto, te whakakotahi i ngā arai ā-tinana, te aroturuki atamai, me ngā ārai kore mahi hei whakakore i ngā mōrearea pahūtanga i tōna pūtake.

Ko te kaupapa matua o te auahatanga haumaru kei roto i te motuhaketanga tino. Mā te ārai whakarewa kua hiritia - he mea hanga mai i ngā koranu kaha-teitei - ka hangaia he arai kore e uru ki waenga i te hau kua pēhia me ngā wāhanga miihini. Mā tēnei ka whakakorea te poke o te hinu whakahinuhinu, ā, ka ārai hoki i te hanganga o ngā ranunga pahū. Hei tāpiri atu ki tēnei, mā ngā motuka kua whakamanahia e te pahūtanga me ngā pūnaha hiko haumaru-ā-roto (e rite ana ki ngā paerewa ATEX/IECEx) ka whakarite kia kore he mura, he werawera rānei e mura ai ngā mea pupuhi, ahakoa i roto i ngā taiao whai hau.

Haunga te ārai, ko te hopu i ngā tūmomo mōrearea i te wā tūturu te pou tuarua o te tiakitanga. Ka mahi tahi ngā hoahoa hiri maha-wāhanga me ngā whatunga pūoko iti e aroturuki tonu ana i te kounga o te hau, ngā rerekētanga pēhanga, me ngā pikinga pāmahana. Mēnā ka kitea e ngā pūoko te ngenge o te kiriuhi, ngā turuturu taumata ppm rānei, ka mahi ngā kawa whakaweto aunoa i roto i ngā mirihekona—he tere ake i ngā wā tauhohenga a te tangata. Mā tēnei whakawhiti maeneene mai i te kitenga ki te mahi ka huri i te whakahaere mōrearea mai i te tauhohenga ki te matapae.

Ka whakaratohia e ngā huānga haumaru kore mahi he tauutuutu nui. Ka tohatohahia te kaha e ngā takirere whakamāmā pēhanga rua me ngā kōpae pakaru i ngā wā o ngā ngaru rerekē, ko ngā pūnaha whakahaere wera matatau ka pupuri i ngā wāhanga nui i raro i te 40% o ngā pāmahana mura aunoa o ngā hau kua whakahaerea. Ka whakakorea ngā mōrearea hiko mā roto i ngā rauemi kawe me ngā tikanga whenua pakari (ātete <1Ω), ka whakakorea ngā pūtake mura huna.

Ko te whakamanatanga ki ngā paerewa o te ao te pou here mō ēnei hangarau. Ko te tutuki i ngā anga pēnei i te ATEX Directive 2014/34/EU (Rohe 0/1/2), IECEx Scheme, me te ASME BPVC Wāhanga VIII e whakamana ana i te rite mō ngā taiao tino kino—mai i ngā teihana whakakī hinu hauwai ki te hanga API rongoā. Ko ia tiwhikete e tohu ana i ngā mano hāora o te whakamātautau whakamanatanga i raro i ngā āhuatanga rahunga whakatauira.

I te mutunga,pūwhakakoi diaphragmKa whakakotahi te haumaru i te pūtaiao rauemi, te hangarau pūnaha, me te mataaratanga mamati. He rapunga whakaaro tēnei e kī ana ko ia hiri, pūoko, me te takirere whakaora ehara i te mea hei whakatutuki noa i ngā ture, engari hei whakarite kia mau tonu te tawhiti i waenga i te mahi me te aituā ina pēhia ana te pāpāho hurihuri.
