Isakhiwo Esidityanisiweyo Esibandayo Somgca Wepayipi Yomlilo

Ulwakhiwo Oludityanisiweyo Olufakwe Kwisixokelelwano Sombhobho Womlilo Umfanekiso Oveziweyo

Inkcazo emfutshane:

Iipayipi ezidityaniswe ngomthungo ojikelezayo zidlala indima ebalulekileyo kumashishini ahlukeneyo, ingakumbi kwizakhiwo ezidityanisiweyo ezenziwe ngokubandayo kunye nombhobho womlilo. Ezi payipi zenziwa ngokugoba rhoqo imicu yentsimbi ibe ziimo ezijikelezayo uze emva koko udibanise ii-spiral seams ukuze zenze iipayipi ezinde eziqhubekayo. Zisetyenziswa kakhulu ekuthuthweni kwezinto ezimanzi, iigesi kunye nezinto eziqinileyo, kunye nokusetyenziswa kwezakhiwo kunye nemizi-mveliso.

a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo:
FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo).
b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

Ukongeza, ekukhuseleni umliloimibhobho, ukusetyenziswa kwemibhobho edibeneyo yomthungo ojikelezayo kubalulekile ukuqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo. Le mibhobho yenzelwe ngokukodwa ukumelana nobushushu obuphezulu kunye noxinzelelo kwaye ifanelekile ukusetyenziswa kwiinkqubo zokukhusela umlilo. Ulwakhiwo oludibeneyo lombhobho odibeneyo luqinisekisa ukuba aluvuzi kwaye lugcina ulungelelwaniso lwesakhiwo naphantsi kweemeko ezinzima, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo yeenkqubo zokukhusela umlilo kunye nokucima umlilo.

Enye yezona nzuzo ziphambili zeumthungo ojikeleziweyo wepayipiyindlela esebenza ngayo kwaye iyakwazi ukuguquguquka kwiindlela ezahlukeneyo zokusebenza. Ezi mbhobho zinokwenziwa ngeendidi ezahlukeneyo zobubanzi kunye nobukhulu ukuze zihlangabezane neemfuno ezithile zeprojekthi. Ukongeza, zinokugqunywa ngezinto zokukhusela ukuphucula ukumelana nokugqwala kunye nokwandisa ubomi bazo benkonzo, ukuze zilungele ukusetyenziswa kwiindawo ezahlukeneyo kunye neemeko.

Iipayipi ezidityaniswe ngomthungo ojikelezayo zinezibonelelo ezicacileyo xa kufikwa ekufakweni nasekugcinweni. Zilula kwaye ziguquguquka, nto leyo eyenza kube lula ukuzithutha nokuziphatha, nto leyo enciphisa ixesha lokufakelwa kunye neendleko zomsebenzi. Ukongeza, ubude bazo obude, obuqhubekayo bunciphisa isidingo soqhagamshelo olongezelelweyo, bunciphisa umngcipheko wokuvuza kwaye buqinisekise inkqubo yepayipi esebenza kakuhle nethembekileyo.

Ukuqukumbela, umbhobho odibeneyo we-spiral seam uyinxalenye ebalulekileyo kumashishini ahlukeneyo, ingakumbi kwizakhiwo ezidibeneyo ezenziwe ngokubanda kunyeumgca wombhobho womliloizicelo. Ulwakhiwo lwayo oluhlala ixesha elide, ukusebenza kwayo okuphezulu kunye nokuguquguquka kwenza ukuba ibe lukhetho lokuqala kwiinjineli, abakhi kunye nabaphathi beeprojekthi. Nokuba bakha izakhiwo ezomeleleyo okanye bayile iinkqubo zokukhusela umlilo ezikhuselekileyo nezithembekileyo, iipayipi ezidityanisiweyo ngomthungo ojikelezayo zisisombululo esibalulekileyo kwiimfuno zeziseko zophuhliso zanamhlanje kunye noshishino.
