Izimiso Nezinzuzo kanye Nemibi Yohlobo Lwe-Flameproof, Ngaphakathi Safe, Nezinhlobo Zengcindezi Enhle

Uhlobo lwe-Flameproof:

Isimiso Sokuvikela Ukuqhuma:

Isimiso sokuvikela ilangabi sibandakanya kusetshenziswa ikesi elivikela ukuqhuma elimelana neziqhumane ngaphakathi, ukuvimbela ingxube yangaphakathi ukuthi ingasakazeki endaweni ezungezile. Zonke izikhala ezingashi zingaphansi kwegebe eliphephile lokuhlola eliphezulu legesi evuthayo okukhulunywa ngayo (ngaphansi kwezimo zokuhlola ezijwayelekile, igebe elikhulu phakathi kwezingxenye ezimbili zejoyinti, okungeke kuthungele ingxube eqhumayo yangaphandle lapho ukugxilisa okulula kwengxube eqhumayo ngaphakathi kwebhokisi kubaselwe). Uma igesi evuthayo ingena emgodini bese ivutha, okubangela ukuqhuma, amalangabi aqhumayo aqukethwe ngaphakathi kwebhokisi, ayikwazi ukuthungela izingxube zangaphandle eziqhumayo, ngaleyo ndlela kuqinisekisa ukuphepha kwendawo ezungezile.

Izinzuzo:

Ingashi ezivalekile zisetshenziswa kabanzi ngomklamo wesakhiwo olula.

Ukubi:

Ziningi futhi zinezidingo ezithile zamakhebuli, amalunga, imigudu, linings, nemikhono (ububanzi obungaphakathi bendandatho yerabha yokuvala ngaphakathi komkhono kufanele bufane nobubanzi bomkhono obungaphandle futhi buvikelwe ngenadi elicindezelayo.; uma kusetshenziswa imikhono yamapayipi ensimbi, kufanele zivalwe ngokupakishwa njengoba kushiwo; uma kusetshenziswa umkhono ongenantambo, i-inlet kufanele ivalwe ngokuvumelana nezidingo ezijwayelekile). Ayivunyelwe ukuvula i-casing ngenkathi inamandla ezindaweni eziyingozi; ukuvula i-casing kudinga amathuluzi akhethekile, futhi ukufakwa nokugcinwa okungalungile kungaholela ezimweni eziyingozi. Izivalo ezivikela umlilo azivunyelwe ku-Zone 0 futhi ngokuvamile asetshenziselwa izinjini, ukukhanya, njll.

Uhlobo Oluphephile Ngaphakathi:

Isimiso Sokuvikela Ukuqhuma:

Kuphephile ngaphakathi, noma “Ukuphepha Kwangaphakathi,” ibhekisela kumgomo wokuvikela ukuqhuma lapho amandla ezinhlansi zikagesi noma imithelela eshisayo ekhiqizwa ngaphakathi kwedivayisi noma izintambo zayo zokuxhuma eziveziwe ekhawulelwe ezingeni elingakwazi ukuvutha. Lokhu kusho ukuthi ngaphansi kokusebenza okujwayelekile noma izimo zephutha ezishiwo, akukho okukhethiwe eziqhumayo ingxube ingavuthwa. Izinyathelo zokuvikela eziyinhloko zihlanganisa ukukhawulela i-voltage yesifunda kanye namanje kanye ne-capacitance ye-circuit kanye ne-inductance, ihlukaniswe yaba Uhlobo ia (ukuvumela amaphuzu amabili amaphutha) futhi Thayipha ib (ukuvumela iphuzu elilodwa lephutha).

Izinzuzo:

Amadivayisi awadingi izintambo ezikhethekile, okwenza kuphephe kakhudlwana ku-opharetha ukuphatha nokulungisa, namakhava angase avulwe ngenkathi inikwe amandla.

Ukubi:

Ayilungele amadivayisi anamandla amakhulu futhi ngokuvamile isetshenziselwa amadivayisi anamandla aphansi ekukaleni, ukulawula, kanye nokuxhumana. ‘Ibe’ uhlobo lungasebenza ku-Zone 0; ‘Ibe’ uhlobo lungasebenza ku-Zone 1.

Izinhlobo Zokucindezela Okuhle:

Isimiso Sokuvikela Ukuqhuma:

Umgomo we ukucindezela okuhle izinhlobo zokuvikela ukuqhuma ezibandakanya ukwethula umoya omusha noma igesi ye-inert ngengcindezi ethile endaweni ebiyelwe, ukuvimbela amagesi avuthayo ukuthi angangeni futhi, kanjalo, ukuvimbela imithombo yokuthungela ekuxhumaneni namagesi aqhumayo, ngaleyo ndlela kuvimbele ukuqhuma. Izinyathelo ezibalulekile zemishini kagesi enomfutho zihlanganisa ukugcina igesi evikelayo (umoya omusha noma igesi engasebenzi) ingcindezi ngaphakathi kwekesi inkulu kune 50 Pascal. Izidingo zezinto zikagesi ezinengcindezi zihlanganisa: isikhwama, amapayipi, futhi ukuxhumana kwabo kufanele kumelane 1.5 izikhathi ingcindezi ephezulu ephezulu kuzo zonke izimbobo zokukhipha umoya ezivale ngaphansi kwezimo ezijwayelekile zokusebenza njengoba kucaciswe umenzi, ngengcindezi encane engu-200Pa. Ukungena komoya ovikelayo kufanele kubekwe endaweni engeyona ingozi, mahhala kumidiya ebolayo; i-exhaust kufanele ibekwe endaweni engeyona ingozi, noma izinhlansi nezinhlayiyana zokuhlukanisa izinhlayiyana kufanele kubhekwe; amadivaysi aqapha ukucindezela komoya nokugeleza kufanele asethwe ngokuya ngeplate yegama lomkhiqizo noma imininingwane eyenziwa ngesandla.

Izinzuzo:

Ingasetshenziswa uma ezinye izindlela zingasebenzi.

Ukubi:

Ukufaka nokunakekela kuyinkimbinkimbi futhi kuyabiza; uma izinsimbi zihlangana ezivuthayo izingxube, kufanele kuthathwe ezinye izinyathelo zokuzivikela; awukho umsebenzi wekhava onamandla ovunyelwe. Ngokuvamile isetshenziselwa izinjini ezinkulu, ama-transformer, namaswishi ane-voltage ephezulu. Ibanga lokusebenzisa elivunyelwe: Izinsimbi ezinemisebenzi yokuvula amandla okuzenzakalelayo zingasetshenziswa ku-Zone 1; amathuluzi anama-alamu acoustic-optic angasetshenziswa ku-Zone 2.

Okwamanje, imikhiqizo yenkampani yethu evikela ukuqhuma ikakhulukazi ifaka ukungashi, iphephile ngaphakathi, kanye nezinhlobo ezinengcindezi. Kungakhathaliseki indlela, umgomo oyinhloko ukuvimbela imishini kagesi ekubeni umthombo wokuthungela. Indlela eyisisekelo yokuvimbela ukuqhuma iwukuqinisekisa ukuthi izakhi ezintathu zokusha—amafutha, i-oxidizer, kanye nomthombo wokuthungela—akuhlali ngesikhathi nendawo. Ngemva kokucabangela izimo zokusebenza ezihlukahlukene, uhlobo olufaneleka kakhulu lomkhiqizo kagesi ongaqhumi kufanele kukhethwe, kucatshangelwa izindleko kanye nokulula kokulungisa, ukunciphisa ubungozi bezingozi zasendaweni.
