API 650 Uphahla Oluntantayo Lokugcina Ugesi Wezindiza: Ubunjiniyela Bomsulwa Nokuphepha
Ukugcinwa kukagesi wezindiza (Aviation Turbine Fuel) kudinga ibhalansi eqinile yokuphepha, ukuthobela imvelo, futhi okubaluleke kakhulu—ukuhlanzeka komkhiqizo ngokuphelele. I-API 650 iyindinganiso yomhlaba wonke yamathangi okugcina ane-welded atmospheric. Lapho kugcinwa ugesi wezindiza, izinga limisela ukwakheka okuthile kophahla oluntantayo, ikakhulukazi ligxile ekwakhiweni kophahla oluntantayo lwangaphakathi (IFR) ukuze kuvikelwe ubumsulwa bakaphethiloli ekungcoleni kwangaphandle.
Ngokungafani nowoyela ongahluziwe, ongakwazi ukubekezelela ukuchayeka ezintweni, ugesi wezindiza uzwela kakhulu. Inhloso eyinhloko yobunjiniyela ukunciphisa "isikhala somhwamuko" (ullage) kuyilapho kuvikelwa ubuso bakaphethiloli emswakameni, othulini, nasezintweni ezingcolile.
Kungani I-API 650 Uphahla Oluntantayo Lwangaphakathi?
Abasebenzisi betheminali kaphethiloli wejethi bathanda Uphahla Olungaphakathi Oluntantayo (IFR)—olulawulwa yi-API 650 Appendix H—kunophahla olungaphandle oluntantayo (EFR) ngezizathu ezintathu ezibalulekile:
1. Ubumsulwa Bomkhiqizo: Uphethiloli wejethi uvame ukukhula kwamagciwane ngenxa yamanzi. I-IFR igcinwa ngaphakathi kuthangi elinophahla olungaguquki, idale indawo evikelekile "yazo zonke izimo zezulu" evimbela imvula, iqhwa, nothuli ukuba kungathinti ubuso bakaphethiloli.
2. Ukulawulwa Kokukhishwa: Ngokuhlala ngqo phezu kobuso baketshezi, uphahla lunciphisa indawo yomhwamuko lapho ama-volatile organic compounds (VOCs) engaqongelela khona. Lokhu kubalulekile ekuhlangabezaneni namazinga e-EPA nawamazwe ngamazwe ekhwalithi yomoya.
3. Ukuncishiswa Kwengozi Yomlilo: Ngokuqeda indawo yomhwamuko, i-IFR ivimbela ukwakheka kwengxube eqhumayo kaphethiloli nomoya, kwehlise kakhulu ingozi yokuthungela umlilo.
Ukuqhathaniswa Kwezobuchwepheshe: Ukuhlelwa Kwamathangi Okugcina Uphethiloli Wejethi
Uma ukhetha phakathi kwezinhlobo zophahla, ithebula elilandelayo lifingqa ukuhwebelana okusebenzayo kwezindawo zikaphethiloli wezindiza:
Isici | Uphahla Oluntantayo Olungaphakathi (IFR) | Uphahla Oluntantayo Olungaphandle (EFR) |
Primary Standard | API 650, Appendix H | API 650, Appendix C |
Ingozi Yokungcola | Iphansi Kakhulu (Ukuvikelwa kophahla olungaguquki) | Okulingene (Uvezwa ezintweni) |
Ukulungiswa | Kuncane (Indawo ehlanzekile) | Okuphezulu (Kudinga ukunakekelwa komsele/ukuvuleka) |
Ukufaneleka Kukaphethiloli Wendiza | Izinga Elinconyiwe | Okuvame Ukungakhuthazwa |
Ukuchayeka Emvelweni | Kuvikelekile emvuleni/othulini | Kuchayeke ngqo |
Izidingo Ezibalulekile Zobunjiniyela Zamathangi Kaphethiloli Wendiza
Ukuze kugcinwe ukuthobela i-API 650 kanye nekhwalithi kaphethiloli, amathangi kumele afake izinsiza ezithile zomklamo:
1. Izinhlelo Zokudonsa Ezintantayo
Ngenxa yokuthi inhlabathi namanzi kungahlala phansi ethangini, amathangi kaphethiloli wendiza kumele asebenzise indlela yokudonsa entantayo. Le payipi idonsa umkhiqizo ngaphansi nje kwendawo engaphezulu koketshezi—indawo ehlanzeke kakhulu—hhayi phansi ethangini.
2. Izinhlelo Zokuvala Ezinobuqotho Obuphezulu
I-“seal” iyisithiyo esiyinhloko phakathi komkhiqizo nomoya. Kaphethroli wendiza:
● Izivalo Eziyinhloko: Ngokuvamile izivalo ezinjengezicathulo zemishini noma amashubhu agcwele uketshezi ahambisana nogqinsi lwethangi.
● Izivalo Ezesibili: Ngokuvamile zidingwa yimithetho yezemvelo ukuze zinikeze isithiyo esengeziwe sokuvikela ukuvuza komhwamuko.
● Ukuhambisana Kwezinto: Izinto zokwenza izivalo kumele zihambisane namakhemikhali ezigcwalisi zikaphethroli wendiza ukuze kugwenywe ukuvuvukala noma ukonakala.
3. Ukuntanta Kwesakhiwo (API 650 Appendix H/C)
Uphahla lwethangi kumele luklanyelwe ukuhlala luntanta ngisho noma izingxenye eziningi zamaphonthoni zephukile. Izibalo kumele zibandakanye isisindo sophahla, izivalo, kanye nezidingo ezingaba khona zokuthwala umthwalo ukuze kufinyeleleke ekulungiseni.
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Kungani ithangi elinophahla olungaguquki ngaphandle kwesizukulwane esintantayo singanconywa kaphethiloli wejethi?
Impendulo: Ithangi elijwayelekile elinophahla olungaguquki lishiya "isikhala somhwamuko" (ullage) esikhulu ngaphezu kaphethiloli. Lesi sikhala sivumela ukuhwamuka okweqile, kukhuthaze ukumuncwa komoya-mpilo, futhi kudale umoya ovutha kalula. Ngaphezu kwalokho, kuveza uphethiloli ekujuleni komswakama, okungaholela ekungcoleni okubangelwa amagciwane.
Umbuzo: Ngidinga umsele wompheme ophahleni oluntantayo lwangaphakathi?
Impendulo: Ngokuvamile, cha. Ngoba i-IFR ivikelwe uphahla olungaguquki, ivikelwe emvuleni naseqhweni. Ngakho-ke, imisele eyinkimbinkimbi yompheme (edingekayo kuma-EFR) ngokuvamile ayidingeki, yenza ukulungiswa kube lula futhi kunciphise ingozi yokuthi "icwilise" (lapho uphahla lungalingani ngenxa yokuqoqwa kwamanzi).
Umbuzo: Ingabe zikhona izidingo eziqondene nokufakwa kwepende emathangeni kaphethiloli wendiza e-API 650?
Imphendulo: Yebo. Imvamisa kudingeka ukufakwa kwepende ngaphakathi ukuvimbela ukugqwala kwensimbi yethangi, okungafaka izinhlayiya zensimbi kaphethiloli. Le pende kumele iqhube ugesi (ukuvimbela ukunqwabelana kukagesi omile) futhi ihambisane nokucwiliswa isikhathi eside kaphethiloli wendiza.
