Indawo Esebenzayo Yezisetshenziswa zikagesi ezinobufakazi bokuqhuma

Ngokusho kwe-GB3836.1-2010 “Ingxenye ye-Explosive Atmospheres 1: Izisetshenziswa Ezijwayelekile Izidingo,” okokusebenza kukagesi okungaqhumi kuklanyelwe ukusebenza endaweni esemkhathini. Izimo ezijwayelekile zomkhathi zihlanganisa:

1. Ukucindezela komkhathi kusuka 0.08 ku 0.11 I-MPa;

2. An umoya-mpilo ukuhlushwa kwe 21% (ngevolumu) emoyeni ojwayelekile, namanye amagesi angasebenzi njenge-nitrogen akha 79% (ngevolumu);

3. I-ambient izinga lokushisa phakathi kuka-20°C no-60°C.

Imvelo yokusebenza kwezinto zikagesi ibalulekile ekuphepheni kwayo. Ngokwesibonelo, izinto zikagesi ezingaqhumi zivame ukucaciswa ukuthi zisebenza emazingeni okushisa aphakathi kuka -20°C kuya ku-40°C. Umfutho womoya ophansi, okusho ukuthi umoya omncane, kungaba nomthelela omubi ekusebenzeni kahle kokupholisa kwamadivayisi kagesi. Ngokunjalo, ukushintshashintsha kwezinga lokushisa lomoya womkhathi kuthonya ukusebenza kokupholisa, ethinta ngqo ukusebenza kahle kwedivayisi.

Lapho imvelo eklanyelwe imishini kagesi ihlukana nezimo zangempela zomkhathi, kubalulekile ukulungisa amapharamitha, ikakhulukazi kumadivayisi anamandla aphezulu, ukugcina amazinga okuphepha.

Izinga lokushisa elikhethiwe lendawo yokusebenza, setha phakathi nesigaba sokuklama, iveza ububanzi bokushisa obuvumelekile bokusebenza kwemishini. Lokhu kushisa kwemvelo kwakha isisekelo sazo zonke izinkomba zokusebenza kwemishini. Umehluko phakathi kwezindawo zangempela neziklanyelwe kungaholela ekungasebenzini kahle noma, ezimweni ezinzima, ukungasebenzi kahle. Ngokuqondile for izinto zikagesi ezingaqhumi, ukweqa izinga lokushisa elinqunyiwe kungase kubeke engcupheni ubuqotho bokuvikela ukuqhuma kwezinhlobo ezithile.

Ngaphezu kwalokho, okuqukethwe komoyampilo womoya kuthinta kakhulu ukuphepha kwamadivayisi kagesi angaqhumi. Izinto zokusebenza ezihloselwe eziqhumayo izingxenye ku- “i-oxygen ecebile” ukulungiselelwa kungase kudale izingozi. Ezimweni ezinjalo, okushintshiwe ukuvutha izakhiwo zamagesi avuthayo zingabekela inselele umsebenzi ojwayelekile wemishini eyenzelwe izimo ezijwayelekile.
