Ikhwalithi Enhle Yephampu Yephampu Yedizili 3 418 403 005 3403-005 Izingxenye Zephampu Dizili 3418403005 3403005 yePump Engine

Umsebenzi wephampu yokujova uphethiloli uwukuletha uphethiloli onengcindezi ephezulu kumjovo kaphethiloli ngesikhathi nangendlela yobuningi ngokwezimo zokusebenza zenjini kadizili kanye nohlelo lokusebenza lwesilinda.

1.Iphampu yomjovo kadizili wemoto enezisilinda eziningi kufanele ihlangabezane nezidingo ezilandelayo

(1))Inani lamafutha ahlinzekwa kusilinda ngalinye liyalingana. Ngaphansi kwesimo sokulinganisa, umehluko ekunikezeni uwoyela we-cylinder ngayinye awukho ngaphezu kuka-3% ~ 4%. Ukunikezwa kukaphethiloli kwepompo yomjovo kaphethiloli kufanele kushintshwe ngokushintsha kwesimo sokusebenza kwenjini ye-diesel, ngakho-ke iphampu yomjovo kaphethiloli kufanele ibe nendlela yokulungisa ukunikezwa kukaphethiloli.
(2) I-engeli engaphambili yokunikezwa kukawoyela yesilinda ngayinye iyafana, futhi iphutha lingaphansi kuka-0.5°~1° i-crankshaft Angle. I-engeli engaphambi kokunikezwa kukaphethiloli kufanele futhi ishintshe nesimo sokusebenza kwenjini ye-diesel, ngakho-ke idivayisi yangaphambi kokujova uphethiloli kufanele ifakwe.
(3) I-engeli yokuphakelwa kukawoyela yesilinda ngayinye iyahambisana.
(4) Ingamisa ngokushesha ukunikezwa kukawoyela ukuze ivimbele umjovo kawoyela ukuthi ungavuzi.

Kunezinhlobo eziningi zamaphampu omjovo kaphethiloli, asetshenziswa kakhulu ezinjinini zedizili, njengephampu yomjovo kaphethiloli esemgqeni we-plunger kanye nephampu yomjovo kaphethiloli wokusabalalisa i-rotor. Ngaphezu kwalokho, kukhona amaphampu - nozzles nokunye.

2. Uchungechunge lwepompo lomjovo wohlobo lwe-plunger

Ngenxa yokuthi amandla e-cylinder eyodwa yenjini kadizili ahluka kakhulu, uma iphampu yomjovo kaphethiloli iklanywe futhi yakhiqizwa ngokuya ngokunikezwa kukawoyela ojikelezayo odingwa amandla osilinda owodwa, ukucaciswa kosayizi wephampu yomjovo kaphethiloli kuzoba kungenakubalwa, kubangele okuningi. ukuphazamiseka ekukhiqizeni nasekusetshenzisweni. Ngakho-ke, abakhiqizi bephampu yomjovo emhlabeni basekelwe emivimbo eminingi ehlukene ye-plunger, iphampu yomjovo ihlukaniswe yaba uchungechunge noma amamodeli ambalwa, bese kuba nobukhulu obuhlukene bezingxenye zokuhlanganisa i-plunger, ukwakha inani lamaphampu omjovo kaphethiloli ngamafutha ahlukene. ukuhlinzeka ngamanani ukuze kuhlangatshezwane nezidingo zezinjini ezihlukahlukene zamandla kadizili. Ithebula 5-4 libala uchungechunge oluningana lwamaphampu omjovo kaphethiloli ase-in-line plunger akhiqizwa eShayina kanye nemingcele yawo eyinhloko.

Iphampu yomjovo kaphethiloli engu-A, B yochungechunge noma A, B uhlobo lwephampu yomjovo kaphethiloli isakhiwo esiyisisekelo siyefana, isakhiwo esivamile sepompo yomjovo we-plunger esemgqeni. Iphampu yomjovo kaphethiloli yohlobo lwe-P inendlela entsha, futhi yamukela umzimba wephampu yokuvala uphawu yebhokisi ngaphandle kokuvula iwindi eliseceleni ukuze kuqiniswe ukwakheka kwephampu yomjovo kaphethiloli. Okulandelayo kuchaza ukwakheka kanye nesimiso sokusebenza sohlobo A kanye nohlobo P lwephampu yomjovo kaphethiloli.

3.Isimiso sokusebenza sephampu yomjovo wohlobo lwe-fuel

Lapho i-camshaft yepompo yomjovo kaphethiloli izungeza, uma i-tappet roller igingqika endaweni engaphansi ye-CAM, i-plunger ima endaweni yesikhungo esiphansi esifile se-plunger. Uma i-roller igingqika iye esigabeni sokuphakamisa i-CAM, i-CAM iphusha i-tappet, futhi i-tappet iphushela i-plunger phezulu, kuyilapho isiphethu se-plunger sicindezelwa. Lapho i-roller igingqika phezu kwe-arc ephezulu ye-CAM, i-plunger ifinyelela endaweni efile ephezulu ye-plunger. Bese i-roller igingqika engxenyeni yokudonsa ye-CAM, isiphethu se-plunger siphusha i-plunger, bese i-plunger iphushela i-tappet phansi kuze kube yilapho i-roller igingqika endaweni ephansi ye-CAM, bese i-plunger ibuyela esitobhini esingezansi se-plunger. Okusho ukuthi, uma ipompo yomjovo kaphethiloli isebenza, ngokuzungezisa kwe-camshaft, i-tappet ne-plunger zibuyiselana emgodini we-tappet kanye nomkhono we-plunger ngokulandelanayo phakathi kwesikhungo esifile esiphezulu nesiphansi se-plunger.
