Isakhiwo Esihlanganisiwe Esihlanganisiwe Somugqa Wepayipi Lomlilo

Incazelo emfushane:

Amapayipi ahlanganisiwe ngomthungo ojikelezayo adlala indima ebalulekile ezimbonini ezahlukahlukene, ikakhulukazi ezakhiweni ezihlanganisiwe ezakhiwe ngokubandayo kanye nomugqa wamapayipi omlilo. Lawa mapayipi enziwa ngokugoba njalo imichilo yensimbi ibe yizimo ezijikelezayo bese ehlanganisa imichilo ejikelezayo ukuze kwakhiwe amapayipi amade aqhubekayo. Asetshenziswa kabanzi ekuthutheni uketshezi, amagesi nezinto eziqinile, kanye nasezisetshenzisweni zesakhiwo nezezimboni.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

In isakhiwo esihlanganisiwe esenziwe ngobandayoukusetshenziswa, ipayipi elihlanganisiwe ngomthungo ojikelezayo libalulekile ekwakheni izakhiwo eziqinile nezithembekile. Lawa mapayipi ngokuvamile enziwa ngensimbi esezingeni eliphezulu futhi angamelana nemithwalo esindayo, okwenza afanelekele amabhuloho, izakhiwo kanye neminye imisebenzi yengqalasizinda.

a. Indlela yokususa i-oxidation ichazwa kanje:
FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo).
b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

Ngaphezu kwalokho, ekuvikelweni komliloamapayipi, ukusetshenziswa kwamapayipi ahlanganisiwe ngomthungo ojikelezayo kubalulekile ukuqinisekisa ukuphepha nokuthembeka kohlelo. Lawa mapayipi aklanywe ngokukhethekile ukumelana namazinga okushisa aphezulu kanye nokucindezela futhi afanele ukusetshenziswa ezinhlelweni zokuvikela umlilo. Ukwakhiwa okuhlanganisiwe kwepayipi lomthungo ojikelezayo kuqinisekisa ukuthi alivuzi futhi ligcina ubuqotho besakhiwo ngisho nangaphansi kwezimo ezimbi kakhulu, okwenza kube yingxenye ebalulekile yezinhlelo zokuvikela umlilo kanye nokunciphisa umlilo.

Enye yezinzuzo eziyinhloko ze-ipayipi elihlanganisiwe lomthungo ojikelezayoukuguquguquka kwayo kanye nokuzivumelanisa nezimo kwezicelo ezahlukahlukene. Lawa mapayipi angakhiqizwa ngobubanzi nobukhulu obuhlukahlukene ukuze ahlangabezane nezidingo ezithile zephrojekthi. Ngaphezu kwalokho, angambozwa ngezinto zokuvikela ukuze kuthuthukiswe ukumelana nokugqwala futhi kwandiswe isikhathi sawo senkonzo, okwenza afaneleke ukusetshenziswa ezindaweni nasezimweni ezahlukene.

Amapayipi ahlanganiswe ngomthungo ojikelezayo anezinzuzo ezicacile uma kukhulunywa ngokufakwa nokugcinwa kwawo. Alula futhi aguquguquka, okwenza kube lula ukuwathutha nokuwaphatha, kunciphisa isikhathi sokufakwa kanye nezindleko zomsebenzi. Ngaphezu kwalokho, ubude bawo obude, obuqhubekayo bunciphisa isidingo sokuxhumeka okwengeziwe, kunciphisa ingozi yokuvuza futhi kuqinisekiswe uhlelo lwamapayipi olusebenza kahle noluthembekile.

Ekuphetheni, ipayipi elihlanganisiwe lomthungo ojikelezayo liyingxenye ebalulekile ezimbonini ezahlukahlukene, ikakhulukazi ezakhiweni ezihlanganisiwe ezakhiwe ngokubandayo kanyeumugqa wepayipi lomliloizinhlelo zokusebenza. Ukwakhiwa kwayo okuhlala isikhathi eside, ukusebenza kwayo okuphezulu kanye nokuzivumelanisa nezimo kwenza kube ukukhetha kokuqala konjiniyela, osonkontileka kanye nabaphathi bephrojekthi. Kungakhathaliseki ukuthi bakha izakhiwo eziqinile noma baklama izinhlelo zokuvikela umlilo eziphephile nezithembekile, amapayipi ahlanganisiwe ngomthungo ojikelezayo ayisisombululo esibalulekile ezidingweni zengqalasizinda yesimanje kanye nezimboni.
