Incazelo kanye Nomgomo Wezinto Zokusebenza zikagesi zohlobo lwe-Flameproof

Incazelo:

Izinto zikagesi ezingaqhumi, ekhonjiswa ngophawu “d,” iwuhlobo lwakudala lwemishini engaqhumi. Amashumi eminyaka, isakhiwo esingashi sibe yisinqumo esiyinhloko ekuthuthukisweni nasekusetshenzisweni kwemishini kagesi engaqhumi. Amadivayisi anjalo kagesi angashi athembekile ekuphepheni kokuqhuma, babe nobuchwepheshe bokukhiqiza obuvuthiwe, futhi ujabulele impilo ende yesevisi. Asetshenziswa kakhulu ezindaweni eziyingozi ezinengxube ehlukahlukene yomoya ovuthayo. Nokho, ngenxa ye angashi isakhiwo, la madivayisi athi asindayo futhi makhulu.

Isimiso Sokuvikela Ukuqhuma:

Ukuphepha nokusebenza kokuvikela ukuqhuma kwalolu hlobo lwemishini kagesi kuqinisekiswa yi-casing eyaziwa ngokuthi “indawo evikela umlilo.”

A “indawo evale amalangabi” ivumela izingxube zegesi-moya ezivuthayo ukuba zishise futhi qhuma ngaphakathi kwebhokisi kodwa ivimbela imikhiqizo yokuqhuma ekuqhumeni imbobo noma ukuphunyuka kunoma yiziphi izindlela eziya ngaphandle ezingase zithungele izingxube eziqhumayo ezizungezile.. Uma nje indawo ephezulu izinga lokushisa yendawo ebiyelwe aweqi izinga lokushisa leqembu elihlosiwe, idivayisi ngeke ibe umthombo wokuthungela ingxube ezungezile yokuqhuma komoya wegesi.

Zisebenza kanje izinto zikagesi ezingashi.

Ukuqonda lesi simiso, singaphetha ngokuthi i-casing yezinto zikagesi ezingashi kufanele zibe namandla anele ukuze zimelane nokucindezela kokuqhuma okukhiqizwa ngaphakathi ngaphandle kokuguquguquka okukhulu noma ukulimala.. Izikhala phakathi kwezingxenye zendawo ebiyelwe engashi, akha amashaneli ukusuka ngaphakathi kuya ngaphandle, kufanele ibe nobukhulu obufanele bemishini obunganciphisa noma buvimbele ukuphunyuka kwemikhiqizo eqhumayo. Ngale ndlela, ukuvutha kwe eziqhumayo Izingxube ze-gas-air ezizungeze imishini ziyavinjelwa. Amazinga okuvikela ukuqhuma kwezinto zikagesi ezingashi ahlukaniswa abe amabanga amathathu: IIA, IIB, kanye ne-IIC. Amazinga okuvikela amathuluzi nawo angahlukaniswa abe amabanga amathathu: a, b, kanye c, evame ukumelelwa ekusebenzeni njenge: Izisetshenziswa zeQembu I, uMa kanye no Mb; Izimpahla zeQembu II, Ga, Gb, kanye noGc.

Indawo ebiyelwe ye izinto zikagesi ezingaqhumi kufanele zenziwe ngezinto ezinamandla amahle omshini, njengensimbi plate, Insimbi, ingxube ye-aluminium, ingxubevange yethusi, insimbi engagqwali, kanye nepulasitiki yobunjiniyela. Amandla nobukhulu begebe kufanele buhambisane nezidingo ezifanele ze-GB3836.2—2010 Explosive Atmospheres Part 2: Izisetshenziswa ezivikelwe ngezivalo ezingashi.
