Fuel fuel circuit: mechanical, electric

Ipompo kaphethiloli - ingxenye yesistimu kaphethiloli yemoto enikeza uphethiloli ohlelweni lokudosa (carburetor / nozzle). isidingo sengxenye enjalo ohlelweni lukaphethiloli luvela ngohlelo lobuchwepheshe lwenjini evuthayo yangaphakathi kanye nethangi legesi elihlobene nomunye nomunye. Enye yezinhlobo ezimbili zamaphampu kaphethiloli afakwe ezimotweni: imishini, kagesi.

Imishini isetshenziswa emishinini ye-carburetor (ukunikezwa kwamafutha ngaphansi kwengcindezi ephansi).

Ugesi - ezimotweni zohlobo lomjovo (uphethiloli uhlinzekwa ngaphansi kwengcindezi ephezulu).

Iphampu yesibaseli engumshini

I-drive lever yepompo kaphethiloli ewumshini ihlale ihamba phezulu naphansi, kodwa ihambisa i-diaphragm phansi kuphela uma kudingekile ukugcwalisa igumbi lepompo. Intwasahlobo ebuyayo iphusha i-diaphragm emuva ukuze inikeze uphethiloli ku-carburetor.

Isibonelo sephampu yamafutha emishini

Idivayisi yephampu yesibaseli umakhenikha:

• ikhamera;
• i-inlet, i-valve yokuphuma;
• i-diaphragm;
• intwasahlobo yokubuya;
• i-drive lever;
• ikhamera;
• i-camshaft.

Iphampu yamafutha kagesi

Iphampu kagesi kagesi ifakwe indlela efanayo: isebenza ngenxa yomgogodla, odonswa ku-valve ye-solenoid kuze kube yilapho othintana nabo bevula, bavala umbane kagesi.

Isibonelo sephampu yamafutha kagesi

Yini efakwe kudivayisi yephampu kagesi kagesi:

• ikhamera;
• i-inlet, i-valve yokuphuma;
• i-diaphragm;
• intwasahlobo yokubuya;
• i-valve ye-solenoid;
• umnyombo;
• abathintwayo.

Isimiso sokusebenza kwephampu yamafutha

Ishayelwa i-diaphragm eyehlayo iye phezulu, njengoba kwakhiwa i-vacuum ngenhla kwe-diaphragm (uma ihlehla), i-valve yokumunca ivuleka lapho uphethiloli ogeleza ngesisefo ungene endaweni yokuphumula ye-supra-diaphragmatic. Lapho i-diaphragm ibuyela emuva (phezulu), lapho ingcindezi idalwa, ivala i-valve yokudonsa, futhi ivule i-valve yokukhipha, enomthelela ekuhambeni kukaphethiloli ngokusebenzisa uhlelo.

Ukuphuka okukhulu kwephampu yamafutha

Ngokuyisisekelo, iphampu yamafutha ihluleka ngenxa yezizathu ezi-2:

• isihlungi sikaphethiloli esingcolile;
• ukushayela ethangini elingenalutho.

Kuzo zombili izimo zokuqala nezesibili, ipompo likaphethiloli lifinyelela emkhawulweni, futhi lokhu kunomthelela ekuphelelweni kwesikhathi ngokushesha kwensiza enikeziwe. ukuze uhlonze ngokuzimela futhi uthole imbangela yokuhluleka kwepompo likaphethiloli, funda isihloko ngezinyathelo zokuqinisekisa.

Ihlola iphampu yamafutha

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
