Tanthauzo ndi Mfundo ya Flameproof Type Electrical Equipment

Tanthauzo:

Zida zamagetsi zosaphulika, chofotokozedwa ndi chizindikiro “d,” ndi mtundu wakale wa zida zosaphulika. Kwa zaka zambiri, mawonekedwe osayaka moto wakhala chisankho choyambirira pakupanga ndi kugwiritsa ntchito zida zamagetsi zomwe sizingaphulike. Zida zamagetsi zotere zomwe zimayaka moto ndizodalirika pakutetezedwa kuphulika, kukhala ndi luso lopanga zinthu, ndi kusangalala ndi moyo wautali wautumiki. Amagwiritsidwa ntchito kwambiri m'malo owopsa okhala ndi zosakaniza zosiyanasiyana zoyaka mpweya wa gasi. Komabe, chifukwa cha osayaka moto kapangidwe, zida izi ndi penapake zolemetsa komanso zazikulu.

Mfundo Yoteteza Kuphulika:

Chitetezo ndi kuphulika kwa zida zamagetsi zamtundu uwu zimatsimikiziridwa ndi casing yomwe imadziwika kuti “chotchinga moto.”

A “chotchinga moto” amalola mpweya woyaka wa gasi zosakaniza kuyaka ndi kuphulika mkati mwa thumba koma zimalepheretsa zinthu zomwe zaphulika kuti zisaphulika kapena kuthawa kudzera munjira iliyonse kupita kunja komwe kumatha kuyatsa zosakaniza zophulika zozungulira.. Bola pamwamba pazipita kutentha wa mpanda si upambana kalasi kutentha kwa gulu anafuna, chipangizo sadzakhala gwero poyatsira kwa ozungulira kuphulika mpweya kusakaniza mpweya.

Umu ndi momwe zida zamagetsi zosayaka moto zimagwirira ntchito.

Kumvetsa mfundo imeneyi, titha kunena kuti choyikapo cha zida zamagetsi zosayaka moto ziyenera kukhala ndi mphamvu zokwanira zamakina kuti zipirire kuphulika komwe kumapangidwa mkati popanda kuwonongeka kwakukulu kapena kuwonongeka.. Mipata pakati pa zigawo za mpanda wosayaka moto, zomwe zimapanga ngalande kuchokera mkati kupita kunja, Ayenera kukhala ndi miyeso yoyenera yamakina yomwe ingachepetse kapena kuletsa kuthawa kwa zinthu zomwe zaphulika. Tiyeni uku, kuyaka kwa zophulika kusakaniza kwa gasi-mpweya kuzungulira zida kumapewedwa. Miyezo yoteteza kuphulika kwa zida zamagetsi zosayaka moto amagawidwa m'magulu atatu: IIA, IIB, ndi IIC. Milingo yachitetezo cha zida imathanso kugawidwa m'magulu atatu: a, b, ndi c, ambiri akuimiridwa mu kuchita ngati: Zida za Gulu I, Ma ndi Mb; Zida za Gulu II, Ga, Gb, ndi gc.

Mpanda wa zida zamagetsi zosaphulika ziyenera kupangidwa kuchokera ku zipangizo ndi mphamvu zabwino zamakina, monga mbale yachitsulo, chitsulo chachitsulo, aluminiyamu aloyi, aloyi yamkuwa, chitsulo chosapanga dzimbiri, ndi mapulasitiki a engineering. Mphamvu ndi kusiyana kwake ziyenera kutsata zofunikira za GB3836.2—2010 Explosive Atmospheres Part. 2: Zida zotetezedwa ndi zotchingira moto.
