Iphuzu lokuqandisa likaphethiloli. Ibheka inani eliqondile
Yini enquma indawo yokuqandisa kaphethiloli?
Uphethiloli ingxenye encane etholakala ku-petroleum. Isici esihlukile sikaphethiloli yikhono lokuxuba kalula nomoya. Ngokwalesi simiso, kwakhiwa izinjini ze-carburetor, ezisebenza kule ndawo kaphethiloli iminyaka engaphezu kwesigamu.
Futhi phakathi kwayo yonke imikhiqizo ecwengiwe, i-petroli enesinye sezakhiwo ezingcono kakhulu zokushisa okuphansi (ingabalwa izindiza, i-rocket nezinye izinhlobo ezikhethekile zikaphethiloli). Ngakho-ke uphethiloli uyoba yiqhwa ngaliphi izinga lokushisa? Isilinganiso sokuqandisa uphethiloli AI-92, AI-95 kanye AI-98 cishe -72 ° C. Kuleli zinga lokushisa, lawa mafutha awashintshi abe yiqhwa, kodwa abe njengejeli. Ngokunjalo, ikhono likaphethiloli lokuxuba nomoya selicishe lalahleka ngokuphelele. Okuyenza ingabi namsebenzi uma iqandisiwe.
Iphuzu lokuthela likaphethiloli lincike kakhulu ekuhlanzekeni kwawo. Ukungcola okuningi okuvela eceleni okungewona ama-hydrocarbons alula kuwo, kuzoba yiqhwa ngokushesha. Isici sesibili izithasiselo eziklanyelwe ukwandisa umkhawulo wokuqandisa okushisayo.
Kukhona izithasiselo ezikhethekile eziklanyelwe ngqo izimo zasenyakatho ekude. Baqhubeka nokwandisa ukumelana kukaphethiloli emazingeni okushisa aphansi. Lokhu kuqinisekisa ukusebenza okungaphazamiseki kwemishini. Emgqeni ophakathi, lezi zengezo azisetshenziswa njengokungadingeki.
Ithini indawo yokuqandisa kaphethiloli?
Iphuzu lokuqandisa likaphethiloli lihlobene nekhono layo lokuhwamuka. Kunendinganiso edinga izindawo zokuhluza ukuze zenze umkhiqizo oqinisekisiwe ukuthi uzohwamuka, uxubane nomoya futhi uthungele egunjini elivuthayo usuka enhlansini. Isibonelo, indawo encane okuzothungela kuyo ibhekwa njengezinga lokushisa lengxube ye-fuel-air, elilingana no -62 ° C.
Ngaphansi kwezimo ezijwayelekile, ngaphansi kwezimo zokusebenza zemoto kanye nokufaka i-refueling kuphela ngophethiloli wekhwalithi ephezulu, uphethiloli kulayini noma ithangi awusoze waba yiqhwa. Akwenzeki ezweni lezwekazi izithwathwa ezinjalo (ngaphandle kwezigxobo). Nokho, kunezimo lapho into enjalo isabonwa.
Uphethiloli wekhwalithi ephansi uqukethe inani elikhulu lokungcola ekubunjweni kwawo. Okunye kwalokhu kungcola akukwazi ukuhlala kumisiwe isikhathi eside futhi kugugudeka kancane kuze kufike phansi ethangini ngemva kokugcwalisa ngakunye. Kancane kancane, ungqimba lwezinto ezingcolisayo kwakheka ethangini. Yilolu ungqimba oluba sengozini kakhulu emazingeni okushisa aphansi. Futhi ngokuhlanganiswa nokunye ukungcola kwemishini emazingeni okushisa angaphansi -30 ° C, le ngxube ingaba yiqhwa esikrinini sokuthatha uphethiloli noma ngaphakathi kwesihlungi. Ngokufanelekile, ukunikezwa kukaphethiloli ohlelweni kuzokhubazeka noma kuvinjwe kakhulu.
Izakhiwo ezibalulekile nazo ziyiphuzu lokubilisa, indawo evuthayo ne-flash point kaphethiloli. Kodwa sizokhuluma ngalokhu ngokwehlukana kwesinye isihloko.
