Chibelesyo chakuzyiba mulilo abusi chakunjizya chikwabilizyo chakwabilila
Kuzibisya
Kukwabililwa akukwabilila mulilo nchintu chipati kubusena buli boonse. Zilayandika kapati mumasena aajisi ntenda aakonzya kupya akupwasuka. Muchiimo eechi, Lukwabililo lwamukati zibelesyo zyakuzyiba mulilo antoomwe azikwabilizyo zyamukati zilagwasya loko. Eezyi nzila zyaalubazu zyakabambilwa kukwabilila mulilo akupwasuka. Balazuzikizya eezi kwiinda mukucheesya manguzu aamagesi akupya muchibelesyo chakuzyiba.
Twaambo tupati:
nZibelesyo zyakuzyiba mulilo zilikwabilidwe loko nzintu ziyandikana loko mubusena buli muntenda bujisi muya uukonzya kupya naakuti zintu zikonzya kuyaka.
nMusyobo ooyu wazibelesyo zilibedelede ulagwisya ntenda zyakuyaka mulilo kwiinda mukulesya nguzu zyakupyasya zyamagesi.
nMumilimo iijisi ntenda mpati mbuli mafuta, kupanga misamu, akubamba zintu zikonzya kuleta ntenda, eeyi nzila taikonzyi kunjililwa busena pe.
nKuziba bube azintu zikonzya kubelesegwa zyamisyobo isiyene-siyene yazibelesyo zyakukwabilila nchintu chipati mukuyaka nzila yakukwabilila mulilo.
nKuchita kabotu kwalukwabililo akukkalwa moyo kwazibelesyo zyakuzyiba zyazumizigwa ambunga zyanyika yoonse zilimbuli Atex zyakasinizyigwa munzila izumizyidwe.
Ino mbuti chibelesyo chakukwabilila mulilo chibeleka biyeni?
nMumasena aakonzya kupya akupwasuka mbuli mafuta aamuwo, misamu, akubamba maila, zibelesyo zyakuzyiba mulilo zyakale zilakonzya kuleta ntenda akaambo kakukonzya kupanga magesi naa kupya kapati, kakuli zibelesyo zyakuzyiba mulilo (IS) zipa kuti kube kubeleka kabotu mumasena aajisi ntenda kwiinda mukubambwa kwaalubazu.
nBusongo bwayo bupati buli munzila yakucesya manguzu: kwiinda mukweendelezya kabotu nguzu zyamagesi azyakupya zili mumulongo, ilasinizya kuti zibelesyo tazikonzyi kupanga mulilo naa kupya kapati mubukkale buli boonse bwakubeleka. Kuti tuzuzikizye makanze aaya, nzila eeyi yeelede kuba achikwabilizyo - chintu chiyandikana loko chibikkidwe aakati ka alamu azibelesyo zya IS, eezyo zikonzya kulesya nguzu zyiingi loko akubamba nguzu zya circuit kuti kazili munsi aachiimo chakukwabililwa chiindi choonse.
nEeyi nzila yakukwabilila yobile (kucheya kwanguzu zyamukati+chikwabilizyo chaanze) ipa kuti IS detector ibe nzila iisyomwa yakulanga mulilo mumasena ajisi ntenda mpati, mpawo kakuli kweendelana azyeelelo zyanyika yoonse zyakukwabilila mulilo mbuli ATEX.
Kutobelezya milawu azyeelelo zyakukwabilila mulilo muUK
Ku UK, kuli milawu miyumu yakubelesya zibelesyo zyakukwabilila mulilo mumasena ajisi ntenda. Kutobelezya milawu eeyi teensi buyo mulawu, pesi nchintu chipati mukukwabilila babelesi akubeleka kabotu.
Milawu iiyandika kapati njakuti Milawu ya Atex. Milawu eeyi yakazwa kumalailile aa EU aajisi makanze aakubamba zyeelelo zyakukwabilila zibelesyo zibelesyegwa mumasena mokukonzya kupwasuka.
Milawu ya ATEX ilayandika kapati kumuntu uli woonse uupanga, uusambala, naa kubelesya zibelesyo zyakukwabilila mumasena oomo mokukonzya kupwasuka. Mumasena aajisi ntenda mukati ka European Union (kubikkilizya a UK), zibelesyo zyoonse anzila zyakukwabilila zyeelede kutobela milawu ya ATEX.
Mbukubede | Bupanduluzi |
ATEX Directive 2014/34/EU | Eezi zibikkilikizya zibelesyo anzila zyakukwabilila zibelesyegwa mumasena aakonzya kupwasuka. |
IEC 60079 | Milawu yanyika yoonse yakubamba, kubikka, akubelesya zibelesyo zyamagesi mumasena aakonzya kupwasuka. |
Kumvwisisisya akutobela milawu eeyi nchintu chipati. Eezi zigwasya kukwabilila lukwabililo aawo notubelesya zibelesyo zyakuzyiba mulilo mumasena ajisi ntenda.
Sala zikwabilizyo zyamukati zyeelede
Swebo, Beijing Pinghe, mbuli sikusambala zikwabilizyo zyaatala, tulijisi bubambe bwakusumpula bujisi makanze aakucesya bupati bwazisinkilizyo, kuzipa kuti zitakatazyi kubelesya, kuubya-ubya kubikka, kucesya ntenda yakulezya, akupa zikwabilizyo zyeendelana anzila zyakubelesya.
PHD-11TN-11 yesu antoomwe a PHD-22TN-1111 zyakabambilwa kuti zibelesyegwe azibelesyo zyakuzyiba busi.
Chitondeezyo chakunjilila muzibelesyo zyakuzyiba mulilo abusi nzintu zikwabilila zili alikke, zikonzya kupa nguzu zyakukwabilila kuli zibelesyo zyakuzyiba mulilo mumasena ajisi ntenda. Zibelesyo zyakuzyiba mulilo zipanga zitondezyo zya 0-40mA eezyo zigwisigwa mumasena aajisi ntenda mpawo zituminwa kumasena aatakwe ntenda, zibeleka mulimo wakukwabilila busi. Eechi chintu chili anguzu zyakugwisya mpawo chili kabotu kubelesyegwa muma DCS/PLC.
Eechi chintu tachiyandiki manguzu aalikke pe, mpawo magesi aakunjizya akugwisya aliimpene.
