Umjovo Omusha Kadizili Oseqophelweni eliphezulu we-CAT C9 Common Rail Injector wezingxenye eziyisipele ze-CAT Engine

Lapho uqala injini ye-diesel ebusika, ukugcinwa kwesistimu kaphethiloli ngezikhathi ezithile kufanele kwenziwe kuqala. Ngaphansi kwezimo ezijwayelekile, indawo yokuqandisa udizili kufanele ibe ngaphansi kuka-3~5 ℃ kunezinga lokushisa elincane lesizini, ukuze kuqinisekiswe ukuthi izinga lokushisa elincane ngeke liqiniswe futhi libe nomthelela ekusetshenzisweni. Ngokuvamile, eningizimu yoMfula i-Yangtze ebusika, kungasetshenziswa uwoyela wedizili omncane ongu-0O°; Ebusika eningizimu yeGreat Wall nasebusika obunzima eningizimu yoMfula iYangtze, kusetshenziswa amafutha edizili alula angu-20*. Ezindaweni ezisenyakatho-mpumalanga, enyakatho-ntshonalanga nasemngceleni ezinobusika obunzima, -35 ° uwoyela we-diesel okhanyayo kufanele usetshenziswe. Inqubo yokukhiqiza udizili wephoyinti eliphansi le-condensate iyinkimbinkimbi futhi intengo iphezulu, ngakho-ke isikhathi sokusebenzisa udizili wephoyinti eliphezulu le-condensate kufanele selulwe ngangokunokwenzeka ngaphansi kwesimo sokushisa esivumayo. Emazingeni okushisa aphansi, lapho udizili wephuzu eliphansi lokuqandisa ungekho, izinyathelo ezifanele zokushisisa zingasetshenziswa ukuze kusetshenziswe udizili osezingeni eliphezulu lokuqandisa.

Kunezindlela ezimbili eziyinhloko zokushisa udizili:

(1) ukushisisa kwegesi ephumayo

Indlela ye-exhaust preheating iwukuthi ipayipi yokukhipha injini ixhunywe ngepayipi ngokusebenzisa ithangi, futhi ukushisa kwemfucumfucu ye-exhaust kusetshenziselwa ukushisa idizili ethangini.

(2) Ukushisisa kwamanzi ajikelezayo

Amanzi okupholisa ajikelezayo ashisisa ngaphambili ngokuwafaka ethangini, noma ithangi lesemishi lisetshenziswa namafutha kungqimba engaphakathi namanzi oqweqwe olungaphandle ukuze ashiswe ngamanzi ajikelezayo.

Indlela yokushisa idizili isetshenziswa ukuqala ngedizili yephuzu eliphansi le-condensate kuqala. Lapho idizili eshisiwe igeleza, ithathelwa indawo udizili wephoyinti eliphezulu le-condensate.
