Iyini Ithangi Elintantayo Langaphandle (EFRT)?
Ithangi elintantayo langaphandle (EFRT) liyithangi lensimbi elikhethekile, elivulekile phezulu, eliyindilinga eliphezulu elinendawo enyakazayo entanta ngqo phezu kwamanzi alondoloziwe. Njengoba uketshezi lumunywa noma lukhishwa, uphahla lukhuphuka futhi lwehle ngokuhambisana nezinga loketshezi.
Ilawulwa ikakhulukazi ngaphansi kwamazinga e-API 650 Isithasiselo C, ama-EFRT akhelwe ngokukhethekile ukugcina uwoyela ongahluziwe, uphethiloli, nama-VOC (ama-Volatile Organic Compounds) anamandla kakhulu. Ngokuhlala ngqo phezu koketshezi, uphahla oluntantayo luqeda isikhala somhwamuko esivame ukunqwabelana ezitsheni ezinophahla olungaguquki, lunciphisa ukukhishwa komhwamuko ngamaphesenti angama-98 futhi lunciphisa kakhulu izingozi zomlilo kanye nokulahlekelwa kwezomnotho.
Isakhiwo Esiyisisekelo Sezakhiwo Nezingxenye
Ngenxa yokuthi ithangi elintantayo langaphandle lisebenza ngaphandle kophahla olungapheli olungaphandle, idekhi yalo ichayeka ngqo ezintweni zezulu ezifana nomoya, imisebe yelanga, nemvula enkulu. Ukuze kuqinisekiswe ukuzinza kwesakhiwo nokuntanta, i-EFRT ihlanganisa izingxenye ezimbalwa ezibalulekile:
● I-Floating Deck: Ivamise ukwakhiwa njengesakhiwo sohlobo lwe-pontoon noma i-double-deck, inikeza ukuntanta okudingekayo ukuze ihlale intanta ngenkathi isekela imithwalo yokusebenza.
● Izinhlelo ze-Rim Seal: Izivalo eziguquguqukayo ezingomshini noma ezifakwe uketshezi ezivala igebe elincane eliyindilinga phakathi komphetho ongaphandle wedekhi entantayo nogobongo lwethangi, zivimba ukuvuza komhwamuko.
● Uhlelo Lokukhipha Amanzi Ophahleni: Inethiwekhi yamapayipi ahlanganisiwe noma aguquguqukayo akhipha ngokuphephile amanzi emvula aqongelele edekhini futhi awehle ngezansi kwethangi ngaphandle kokungcolisa umkhiqizo ogciniwe.
● Iliyisi Egingqikayo: Iliyisi enehinge, eziqondanisa ngokwayo enamathiselwe kugobolondo olungaphezulu, enikeza abasebenzi ukufinyelela okuphephile, okuqhubekayo endekeni entantayo kunoma yiliphi izinga loketshezi.
● Imishini Emelana Nokuzungeza: Iziqondisi zesakhiwo ezivimbela indeke entantayo ukuthi ingazungezi noma ingahlangana nogobolondo lwethangi ngesikhathi sokugcwalisa nokukhipha.
Ithebula Lokuqhathanisa: Amathangi Antantayo Angaphandle vs. Angaphakathi
Isici / Ipharamitha | Ithangi Elintantayo Elingaphandle (EFRT) | Ithangi Elintantayo Langaphakathi (IFR) |
Isivalo Esingaphezulu | Okuvulekile (Uvezwe ngokugcwele emoyeni) | Ivaliwe phezulu ngophahla olungaphezulu olungaguquki noma i-dome |
Izinga Lokulawula | I-API 650 Isithasiselo C | I-API 650 Isithasiselo H |
Umthelela Wesimo Sezulu | Ingaphansi kwemvula, iqhwa, nemithwalo yomoya; idinga ukukhipha amanzi okuphuthumayo | Ivikeleke ngokuphelele ezintweni zezulu |
Izicelo Eziyinhloko | Amatheminali kawoyela ongahluziwe, izinqolobane zikaphethiloli onamandla oguquguqukayo | Amafutha ezindiza (Jet A-1), i-ethanol, amakhemikhali ahlanzekile aphezulu |
Ukulawulwa Kokuhwamuka | Ukusebenza kahle okuphezulu (Ukuncishiswa okungu-98% uma kuqhathaniswa nophahla olungaguquki) | Ukusebenza kahle okuphezulu kakhulu (Kuqeda ngokuphelele ukukhuhleka komoya) |
Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Iyini injongo eyinhloko yethangi elintantayo elingaphandle?
Impendulo: Injongo eyinhloko ukunciphisa ukukhishwa kwezinto eziphilayo eziguquguqukayo (VOC) nokuvimbela ukuhwamuka komkhiqizo ngokuqeda isikhala somhwamuko ngaphezu kobuso boketshezi ezinqolobaneni ezinkulu zikaphethiloli.
Umbuzo: Amanzi emvula alawulwa kanjani ethangini elintantayo elingaphandle elivulekile?
A: Amanzi emvula aqoqana emphemeni aqoqwa ngemisele engaphezulu bese eqondiswa ngepayipi elikhethekile eliguquguqukayo noma elinamalunga elihla liye esitokisini sokukhipha amanzi esivalekayo esisekelweni sethangi.
Q: Iyiphi indinganiso yobunjiniyela elawula ama-EFRT?
A: Embonini yamazwe ngamazwe yezimboni kanye nobunjiniyela bamafutha, amathangi anophahla oluntantayo angaphandle aklanywa futhi akhiwe ngokuvumelana ne-API Standard 650, Isithasiselo C, echaza ukuntanta kwesakhiwo, ukubekwa kwe-wind-girder, kanye nokubekezelela kwe-rim seal.
Q: Kungani ama-EFRT ethandwa kunamathangi anophahla olungaguquki kawoyela ongahluziwe?
A: Uwoyela ongahluziwe uqukethe izingxenye ezihwamukayo ezihwamuka ngokushesha esikhaleni esijwayelekile sophahla olungaguquki. Ama-EFRT avimbela ukulahlekelwa okukhulu komkhiqizo wezomnotho, anciphisa ukungcola kwemvelo, futhi ehlisa kakhulu ingozi yokunqwabelana komhwamuko oqhumayo.
