Iphampu Yekhwalithi Ephezulu Yokujova Udizili BHT6P120R Izingxenye Zenjini Yephampu Yezibaseli ze-Weichai Deutz Wd615 Lgmg

Indima:Iphampu yomjovo kaphethiloli iyingxenye ebaluleke kakhulu ohlelweni lokuphakelwa kukadizili futhi ibizwa ngokuthi "inhliziyo" yenjini kadizili.

Umsebenzi:Ngokusho komthwalo wenjini kadizili, hambisa udizili onengcindezi ephezulu kumjovo njalo nangomthamo. Uhlobo lwenjini kadizili olusetshenziswa kakhulu yilena: iphampu yomjovo we-plunger.

Izingxenye:Iphampu yomjovo kaphethiloli we-plunger iqukethe izingxenye ezilandelayo: ithangi likaphethiloli, iphampu yokudlulisa uphethiloli, ipayipi likaphethiloli elinengcindezi ephansi, isihlungi sikaphethiloli, iphampu yomjovo kaphethiloli, ipayipi likaphethiloli elinengcindezi ephezulu, isijojo sikaphethiloli nepayipi elibuyayo, njll.

Inqubo yokusebenza:Uphethiloli osethangini likaphethiloli uthunyelwa empompini yokujova uphethiloli ngesihlungi sikaphethiloli ngengcindezi ethile (0.15~0.4MPa) ngephampu yokudlulisa uphethiloli. I-high-pressure fuel okukhiphayo empompini yomjovo kaphethiloli ingena kumjovo kaphethiloli ngepayipi likawoyela elinomfutho ophezulu futhi ijovelwe ekamelweni elivuthayo. Njengoba umthamo wokuphakela uphethiloli wephampu yokudlulisa uphethiloli umkhulu ngokuphindwe izikhathi ezingu-3-8 kunepompo lomjovo kaphethiloli, uphethiloli oweqile ubuyela ethangini likaphethiloli ngevalvu yokukhulula efakwe kusihlungi (ephinde ilawule ukucindezela kokulethwa kukaphethiloli). Uma i-valve yokusiza ihlelwe ngaphandle kwegumbi lokungena likawoyela lephampu yomjovo kaphethiloli, wonke uphethiloli uzogeleza egumbini lokungena likawoyela lepompo yomjovo kaphethiloli, futhi umphumela wokupholisa ungcono. Kodwa-ke, ngesikhathi esifanayo, isihlungi sidinga ukudlula wonke uphethiloli, ngakho ngezinye izikhathi ubukhulu kufanele bukhuliswe. Uphethiloli ovuzayo kumjovo ubuyela ethangini likaphethiloli ngepayipi lokubuyisela uphethiloli (lingase futhi lixhunywe epayipini elikhulu lokubuyisela uphethiloli). Akuvunyelwe neze ukuxhuma ipayipi lokubuyisela lomjovo epayipini elinomfutho othile, njengepayipi elisuka empompini kawoyela liye kusihlungi. Kungcono ukuxhuma amapayipi kawoyela awo wonke ama-injection epayipini elihlukile lokubuyisela uwoyela elingacindezelwe ukuze ageleze abuyele ethangini. Ezinye izinjini zikadizili zinethuluzi elenza lonke uhlelo lukawoyela lukwazi ukususa umoya ngokuzenzakalelayo. Okusho ukuthi, kufanele kube nomehluko wobude epayipini ukusuka kusihlungi ukuya empompini yokujova uphethiloli ukuze kuqinisekiswe ukuthi amabhamuza omhwamuko womoya nophethiloli epayipini angakhuphukela phezulu kwesisefo. Ukusuka lapho igeleza ngepayipi elichichimayo iye ethangini likaphethiloli.
