Fuel pump circuit: mechanical, electric

Pombi yepeturu - chinhu chemafuta system yemotokari inopa mafuta kune dosing system (carburetor / nozzle). kudiwa kwechikamu chakadaro muhurongwa hwemafuta kunoonekwa kuburikidza nehunyanzvi kurongeka kweinjini yekupisa mukati uye gasi tangi maererano nemumwe. Imwe yemhando mbiri dzepombi dzemafuta dzakaiswa mumotokari: mechanical, magetsi.

Mechanical inoshandiswa mumashini e carburetor (mafuta anopihwa pasi pekumanikidzwa kwakaderera).

Magetsi - mumotokari dzemhando yejekiseni (mafuta anopiwa pasi pekumanikidzwa kukuru).

Mechanical mafuta pombi

Iyo drive lever yemuchina wepombi yemafuta inogara ichikwira nekudzika, asi inofambisa diaphragm pasi chete pazvinenge zvakakodzera kuzadza imba yepombi. Chitubu chekudzoka chinosundira diaphragm kumashure kuti ipe mafuta kune carburetor.

Muenzaniso wepombi yemafuta emagetsi

Mechanical mafuta pombi mudziyo:

• kamera;
• inlet, valve outlet;
• diaphragm;
• dzoka chitubu;
• drive lever;
• cam;
• camshaft.

Pombi yemafuta emagetsi

Iyo pombi yemagetsi yemafuta inoshongedzerwa nenzira yakafanana: inoshanda nekuda kweiyo core, iyo inoswededzwa muvharuvhu ye solenoid kusvikira maatanidziro avhurika, achidzima magetsi.

Muenzaniso wepombi yemafuta emagetsi

Izvo zvinosanganisirwa mune yemagetsi mafuta pombi mudziyo:

• kamera;
• inlet, valve outlet;
• diaphragm;
• dzoka chitubu;
• solenoid valve;
• moyo;
• contacts.

Nheyo yekushanda kwepombi yemafuta

Inofambiswa nediaphragm inokwira nekudzika, sezvo vacuum inogadzirwa pamusoro pe diaphragm (kana ichifamba pasi), vharafu yekukwevera inovhura iyo peturu inoyerera nemusefa ichienda kune supra-diaphragmatic recess. Kana iyo diaphragm inofamba ichidzokera kumashure (kumusoro), kana kudzvanywa kwagadzirwa, inovhara vharafu yekusveta, uye inovhura vheji yekuburitsa, iyo inobatsira pakufamba kwepeturu kuburikidza nehurongwa.

Kuputsika kukuru kwepombi yemafuta

Chaizvoizvo, pombi yemafuta inokundikana nekuda kwezvikonzero zviviri:

• tsvina yemafuta sefa;
• kutyaira patangi risina chinhu.

Muzviitiko zviviri zvekutanga uye zvechipiri, pombi yemafuta inomhanya kusvika kumuganhu, uye izvi zvinobatsira pakupera kwekukurumidza kwechigadzirwa chakapiwa. kuitira kuti uzviongorore wakazvimiririra uye uwane chikonzero chekutadza kwepombi yemafuta, verenga chinyorwa pamatanho ekusimbisa.

Kuongorora pombi yemafuta

Проверить работу бензонасоса можно в 5 или 7 этапов. Для этого нужно сначала начать с предохранителя и заканчивая проверкой давления. Имея мультиметр, манометр и АКБ с проводком Подробнее
