Pampu Yotentha Yogulitsa Mafuta a Dizilo 02112860 ya Deutz Dizilo Magawo

(1) mfundo yogwira ntchito: jekeseni yamagetsi yamagetsi ya monobloc imagawidwa m'magawo otsatirawa a ntchito: valve ya monobloc pump solenoid valve imayikidwa kumtunda kwa pampu ya monobloc, valavu ya solenoid imatulutsa mphamvu, njira yobwerera imatsegulidwa. , monobloc pump plunger ngakhale itayamba kupopera mafuta, komanso sangathe kukhazikitsa kupanikizika kwakukulu, pokhapokha pamene valve solenoid ipatsidwa mphamvu, njira yobwerera imatsekedwa, kuthamanga kwa mafuta kudzawonjezeka mofulumira; mafuta othamanga kwambiri kudzera mu chitoliro chamafuta othamanga kwambiri kulowa mu jekeseni kuti apange jekeseni wamafuta. Pamene valavu ya solenoid imachotsedwa mphamvu, njira yobwezera mafuta imatsegulidwa, ndipo kuthamanga kwa mafuta kumasefukira mofulumira, ndipo jekeseni imasiya. Valavu ya Solenoid yokhala ndi mphamvu kwakanthawi imatsimikizira kuchuluka kwamafuta ozungulira.
(2) njira yolipirira: valavu ya solenoid ilibe mphamvu, pomwe plunger imatsika, kupanikizika kwamkati kwa jekeseni kumakhala kotsika kuposa kuthamanga kwa jekeseni wamagetsi otsika otsika, mafuta otsika amalowa mkati. jekeseni wothamanga kwambiri kudzera polowera pa mkono wa plunger.
(3) Njira yodutsa: pamene plunger ikukwera, mafuta omwe ali mu plunger amaponderezedwa, koma ngati valavu ya solenoid idakali yotsika mphamvu, kuthamanga kwa mafuta mu plunger kumatsimikiziridwa ndi kutsegula kwa magetsi. valavu yobwezeretsanso, yomwe imakhala yotsika kwambiri kuposa kutsegulira kwa jekeseni, kotero kuti mafuta abwererenso ku thanki yamafuta kudzera munjira yobwerera.
(4) Kulowetsa jekeseni: Pakukwera kwa plunger, ngati chipangizo chowongolera zamagetsi (ECU) chimatumiza chizindikiro kuti chiwongolere jekeseni panthawi inayake, kuti valavu ya solenoid ikhale ndi mphamvu, ndiye kuti njira yobwerera imatsekedwa, ndipo plunger cavity imapangidwa kukhala voliyumu yotsekedwa, ndi kukwera kwa plunger, mafuta mu voliyumu yotsekedwa amaponderezedwa, ndipo kuthamanga kumakwera mofulumira, ndipo kuthamanga kumapeto kwa nozzle. jekeseni imakwera kwambiri, ndipo jekeseni wotsegulira jekeseni (pafupifupi 300 bar) ndi wapamwamba kuposa wa jekeseni, ndiye kuti kuthamanga kwa mafuta kudzatsimikiziridwa ndi kuthamanga kwa valve yobwereranso, komwe kumakhala kotsika kwambiri kuposa kutsegulira kwa jekeseni. Kuthamanga kukakwera kuposa kuthamanga kwa jekeseni (pafupifupi 300 bar), jekeseni imatsegulidwa ndipo mafuta amalowetsedwa mu chipinda choyaka. Kuthamanga kwakukulu kwa jakisoni kumafika 1800 bar.
(5) Njira yotsitsa: Pamene chizindikiro chowongolera kugunda kwa jekeseni chikutha, valavu ya solenoid imachotsedwa mphamvu, njira yobwerera imatsegulidwanso, mafuta akusefukira, kupanikizika mu chipinda cha plunger komanso mumphuno kumatsika mofulumira, mphuno yatsekedwa, ndipo jekeseni imatha.
