He aha te Takirere Whakamutu Āwhati (ESDV): Te Mātāpono Mahi

He aha te Takirere Whakamutu Āwhati (ESDV)?

I roto i te ao nui o ngā tipu tukatuka ahumahi, inā koa ko ngā whare hanga hinu me te hau, ngā tipu matū, me ngā whare whakaputa hiko, ehara i te mea he kaupapa matua te haumaru – engari he mea tino nui. Kei te ngako o te tiaki i ngā kaimahi, te tiaki i te taiao, me te aukati i ngā kino kino rawa kei reira tētahi taputapu nui: teTakirere Whakamutu Āwhati(ESDV), e kiia pinepinetia ana hoki heTakirere Whakamutu (SDV)i roto i ngā Pūnaha Taputapu Haumaru (SIS).

He ESDV tētahitakirere motuhake, e whakahohea aunoa anai hangaia mō tētahi kaupapa matua: kia tere, kia pono hoki te wehe i ngā wāhanga o te rere o te tukanga (ngā wai, ngā hau, ngā wai maha-wāhanga rānei) mēnā he āhuatanga ohorere kua tautuhia. Kāore i rite ki ngā takirere whakahaere e whakarerekē ana i te rere hei whakahaere i te tukanga, he kaiwhakahaere rua ngā ESDV – he tuwhera katoa (e tuku ana i te rere i te wā mahi noa) he kati katoa rānei (e ārai ana i te rere i te wā ohorere). Ko tā rātou mahi matua he mahi heiarai tinana tuatahite aukati i te tukunga kore whakahaere o ngā rauemi morearea ina hipa ana i ngā rohe haumaru tino nui.

He aha te kore e taea te whiriwhiri i ngā ESDV mō te haumaru

Ka tino kino ngā hua o te kore e wehe i te rere o te tukanga i ngā wā ohorere pēnei i te ahi, te turuturu, te pēhanga nui, te rahunga o ngā taputapu, te ngaronga rānei o te aukati. He wāhanga nui ngā ESDV o ngā Mahi Taputapu Haumaru (SIF) i roto i te Pūnaha Taputapu Haumaru whānui (SIS). Kua hangaia ēnei pūnaha kia rite ki ngā paerewa o te ao (IEC 61511 / ISA 84) me te tohu i ngā Taumata Haumaru (SIL) i runga i te whakaiti i te mōrearea me whakatutuki.

Ngā Āhuatanga Matua e Whakamārama ana i te ESDV:

1. Hoahoa Haumaru-Raru:Koinei te mātāpono matua. Kua hangaia ngā ESDV kia *neke aunoa* ki tō rātou āhua haumaru (tata tonukua kati katoa, engari i ētahi wā *tuwhera* i roto i ngā āhuatanga motuhake pēnei i te puna wai whakamatao i te wā o te ahi) ina ngaro te pūtake hiko whakahohe (hiko, pēhanga hau, pēhanga waipēhi) ina whiwhi rānei i tētahi tohu wehenga motuhake mai i te SIS. Mā tēnei ka noho haumaru ahakoa ka ngaro te hiko, te mana whakahaere rānei o te tipu.

2. Te Pono me te Wātea Nui:He tino uaua te hoahoa, te hanga, te whakamātautau, me te whakamana i ngā ESDV. Me mahi tonu i ngā wā katoa e hiahiatia ana. He mea noa te maha o ngā wāhanga nui (pēnei i ngā solenoid).

3. Wā Katinga Tere:He mea nui te tere i ngā wā ohorere. Kua tohua ngā ESDV kia kati i roto i ngā wā poto rawa, i te nuinga o te wā1 ki te 5 hēkona, i runga i te rahi o te takirere, te momo, me te whakaritenga haumaru motuhake (taumata SIL).

4. Hiritanga Pai:Ina kati, me whakarato e ngā ESDV hehiri piri-pupuhihei ārai i te turuturu o te wai tukanga morearea.

5. Hanganga Pakari:I hangaia kia tū atu ki ngā āhuatanga tukanga uaua (te pēhanga teitei, te pāmahana, ngā wai waikura) me te tūponotanga o te mura ahi (he mea whakahau te hoahoa haumaru-ahi e ai ki te API 607/6FA, ISO 10497).

6. Mana Motuhake:Ka whiwhi tika ngā ESDV i tā rātou tohu hinga mai i te Pūnaha Taputapu Haumaru (SIS) motuhake, ehara i te pūnaha whakahaere tukanga noa (BPCS). He mea nui tēnei wehenga mō te pono.

Te Tirohanga Haumaru: Te Whakaaturanga P&ID o te Rerewē Whakamutu ohorere

Ko ngā Kauwhata Paipa me ngā Taputapu (P&ID) te reo whānui mō ngā kaihanga tukanga. He tohu motuhake ā ngā ESDV hei wehewehe i a rātou mai i ētahi atu momo takirere, ā, e whakaatu mārama ana i tā rātou mahi haumaru nui.

* Mō te ESDV, ko tēnei tapawhā te tikangawhakakīia ki te pango mārōrāneipao.

* Ngā reta"ESD", "SD", rānei"XV"(ko X te tohu mō tētahi tohu motuhake, ko 'S' te tikanga he whakaweto) ka whakaaturia māramatia i te taha, i roto rānei i te tohu whakatere.

* Te Mahi i Rahua:Ko te mahi haumaru-kore e tohuhia ana e ngā tohu e tata ana ki te kaiwhakaoho:

* FC (Kati Rahua):He pere e tohu ana ki te tinana takirere, ki ngā reta rānei "FC". Koinei te mea tino noa mō ngā ESDV.

* FO (Kāore i te Tuwhera):He pere e anga atu ana i te tinana takirere, i ngā reta rānei "FO". E whakamahia ana i roto i ngā horopaki motuhake.

* Tau Pūrere Mirumiru me te Tohu:E hono tonu ana te ESDV ki te SIS. Ka whakaaturia tana mahi e temirumiru taputapu(he tapaono, he porowhita rānei te tikanga) e honoa ana ki te tohu whakatere takirere mā te rārangi pītiti. Ko te tau tohu i roto i te mirumiru e whai ana i ngā paerewa tipu engari e tohu mārama ana ko tētahi wāhanga o te SIS (hei tauira, ZV-1001, ko te 'Z' te tohu mō te SIS/ESD, ko te 'V' mō te takirere).

Mātāpono Matua: Me pēhea te Mahi a te Rerewē Whakamutu Āwhati

Ko te kaupapa mahi e whakawhirinaki ana ki tehaumaru-korete hoahoa me te urupare a te kaiwhakaoho ki te ngaronga tohu, ki te ngaronga pūngao rānei. Anei te wehewehenga:

Mō te whakamahinga ESDV, *me* whakauru hetikanga haumaru-mīhini, he puna te nuinga, ka whakamahia ina ngaro te mana hei akiaki i te takirere ki tōna āhua haumaru. Tērā pea ka whakakahangia te motuka e te pākahiko tāpiri mō te haerenga whakamutunga mena ka kore te mana *i muri* i te whiwhinga o te tohu engari i mua i te katinga.

* Ngā PaingaKāore e hiahiatia he pūnaha hau/waipēhi, he tūnga tika (ahakoa kāore e hiahiatia mō te ESD), he taipana teitei.

* Ngā ngoikoretangaHe puhoi ake ngā wā kati i te whakataurite ki te mana wai/puna, he nui ake te utu, he uaua te pūnaha puna, he tūponotanga pea o te mura (me whai tiwhikete mō ngā wāhi morearea).

* Te Whakamahinga NoaNgā wāhi kāore e taea te tuku hau/waipēhi, ngā wāhi iti ake rānei kāore e tino hira te tere. Kāore i te tino kitea mō ngā tono ESDV tere-tiketike nui atu i te puna whakahoki-whakakaha-wai.

He mea nui ia hēkona: Te wā kati o te takirere whakaweto ohorere

Mā te kati tere ka whakaitihia te tukunga, ka whakaitihia te kaha o te aituā (te rahi o te ahi, te marara o ngā kapua paitini, te turuturu taiao).

* Ngā Whakaritenga Noa:Ko ngā wā kati ESDV ka tohua i roto i te whānuitanga o1 ki te 5 hēkonamai i te tīmatanga o te tohu whati ki te whakatutukitanga o te katinga katoa me te hiri. Ko ngā takirere iti ake (hei tauira, 2-6 inihi) ka eke ki te 1-2 hēkona. Ko ngā takirere nui ake (hei tauira, 24 inihi+) me ngā takirere kuaha rānei, ka roa pea ki te 5 hēkona, neke atu rānei, engari he mea pai tonu te tere ake.
