Kupisa Kutengesa Diesel Fuel Unit Pump 02112860 yeDeutz Diesel Injini Zvikamu

(1) kushanda musimboti: yemagetsi inodzorwa monobloc pombi jekiseni system yakakamurwa kuita nhanho dzinotevera dzekushanda: monobloc pombi solenoid valve yakaiswa muchikamu chepamusoro chepombi yemonobloc, solenoid valve inobviswa-energized, nzira yekudzoka yakazaruka. , monobloc pombi plunger kunyange kana yatanga kupomba mafuta, asi zvakare haigoni kugadza yakakwirira-kudzvinyirira, chete kana solenoid valve ichisimbiswa, nzira yekudzoka yakavharwa, iyo mafuta emafuta achakurumidza kuwedzera; high-pressure mafuta kuburikidza ne-high-pressure mafuta pombi kupinda mujekiseni kuita jekiseni remafuta. Kana iyo solenoid valve ichibviswa-energized, nzira yekudzoka kwemafuta inovhurwa, uye mafuta emafuta anokurumidza kuputika, uye jekiseni rinomira. Solenoid valve inopihwa simba kwenguva yakati inotarisa huwandu hweiyo cyclic oiri inopa.
(2) nzira yekuchaja: iyo solenoid valve haina simba, apo plunger inofamba pasi, kumanikidzwa kwemukati kwejekiseni system kunenge kwakaderera pane kudzvanywa kwejekiseni kweiyo yakaderera-kudzvanywa kwemafuta edunhu, iyo yakaderera-kumanikidza system mafuta inopinda mukati. high-pressure injection system kuburikidza neinopinza pane plunger sleeve.
(3) Bypass process: kana plunger ichisimuka, mafuta ari mupunga mhango anomanikidzwa, asi kana solenoid vharafu ichiri mu de-energized state, kudzvanywa kwemafuta mune plunger cavity kuchatemwa nekuvhurwa kwekumanikidza kweiyo. kudzorera vheji yekuyamura, iyo yakaderera zvakanyanya kudarika kuvhurika kwekumanikidza kwejekiseni, kuitira kuti mafuta adzoke achidzokera kune tangi yemafuta kuburikidza nemugero wekudzoka.
(4) Injecting process: Panguva yekusimuka kweplunger, kana iyo electronic control unit (ECU) inotumira chiratidzo chekudzora jekiseni pulse pane imwe nguva, kuitira kuti solenoid valve ine simba, ipapo nzira yekudzoka yakavharwa, uye iyo plunger cavity inoumbwa ikava vhoriyamu yakavharwa, nekukwira kweiyo plunger, mafuta ari muvhavha yakavharwa anomanikidzwa, uye kumanikidza kunokwira nekukurumidza, uye kumanikidza kumagumo emuromo we. jekiseni rinokwira zvakanyanya, uye injector yekuvhura pressure (inenge 300 bar) yakakwira kupfuura iyo yejekiseni, ipapo mafuta emafuta anozotemwa nereturn relief valve opening pressure, iyo irikure yakaderera pane injector yekuvhura pressure. Kana kudzvinyirirwa kwakakwirira kudarika kuvhurika kwejekiseni (inenge 300 bar), jekiseni rinovhura uye mafuta anoiswa mukamuri rinopisa. Iyo yakanyanya jekiseni pressure inosvika 1800 bar.
(5) Kuburutsa maitiro: Kana chiratidzo chekudzora jekiseni pulse chinopera, solenoid valve inobviswa simba, nzira yekudzoka inovhurwazve, mafuta anofashukira, kudzvanywa mukamuri yeplunger pamwe neinodonha inodonha nekukurumidza, iyo muromo yakavharwa, uye chirongwa chejekiseni chinopera.
