Kuzungulira kwapampu yamafuta: makina, magetsi

Mpope mafuta - gawo la dongosolo lamafuta agalimoto lomwe limapereka mafuta ku dongosolo la dosing (carburetor / nozzle). kufunikira kwa gawo loterolo mu dongosolo lamafuta kumawonekera kudzera mu dongosolo laukadaulo la injini yoyaka mkati ndi tanki yamafuta wachibale wina ndi mnzake. Imodzi mwa mitundu iwiri ya mapampu amafuta amayikidwa m'magalimoto: makina, zamagetsi.

Makina amagwiritsidwa ntchito m'makina a carburetor (mafuta operekera pansi pamavuto otsika).

Magetsi - m'magalimoto amtundu wa jakisoni (mafuta amaperekedwa mopanikizika kwambiri).

Pampu yamagetsi yamakina

Chingwe choyendetsa cha pompu yamafuta imasuntha nthawi zonse m'mwamba ndi pansi, koma imasuntha diaphragm pansi pokhapokha pakufunika kudzaza chipinda chopopera. Kubwerera kasupe kumakankhira diaphragm m'mwamba kuti ipereke mafuta ku carburetor.

Chitsanzo cha makina opangira mafuta opangira mafuta

Chida chopopera mafuta pamakina:

• kamera;
• cholowera, valavu yotulukira;
• diaphragm;
• kasupe wobwerera;
• lever yoyendetsa;
• kamera;
• camshaft.

Pampu yamagetsi yamagetsi

Pampu yamagetsi yamagetsi imakhala ndi njira yofananira: imagwira ntchito chifukwa chapakati, yomwe imakokedwa mu valavu ya solenoid mpaka olumikizana atsegule, kuzimitsa magetsi.

Chitsanzo cha pampu yamagetsi yamagetsi

Zomwe zikuphatikizidwa mu chipangizo cha pampu yamagetsi yamagetsi:

• kamera;
• cholowera, valavu yotulukira;
• diaphragm;
• kasupe wobwerera;
• valve solenoid;
• pachimake;
• olumikizana nawo.

Mfundo yogwiritsira ntchito pampu yamafuta

Imayendetsedwa ndi diaphragm yomwe imapita mmwamba ndi pansi, popeza mpweya umapangidwa pamwamba pa diaphragm (pamene ukuyenda pansi), valavu yoyamwa imatsegula momwe mafuta amayenda kupyolera mu fyuluta kupita ku supra-diaphragmatic recess. Pamene diaphragm imabwerera mmbuyo (mmwamba), pamene kupanikizika kumapangidwira, kumatseka valavu yoyamwa, ndikutsegula valavu yotulutsa, yomwe imathandizira kuyenda kwa mafuta kudzera mu dongosolo.

Kuwonongeka kwakukulu kwa pampu yamafuta

Kwenikweni, pampu yamafuta imalephera pazifukwa 2:

• zonyansa mafuta fyuluta;
• kuyendetsa pa thanki yopanda kanthu.

Pazochitika zonse zoyambirira ndi zachiwiri, pampu yamafuta imadutsa malire, ndipo izi zimathandizira kutha kwachangu kwazinthu zomwe zaperekedwa. kuti mudziwe nokha ndikupeza chifukwa cha kulephera kwa mpope wamafuta, werengani nkhaniyo pamasitepe otsimikizira.

Kuyang'ana pampu yamafuta

Mukhoza kuyang'ana ntchito ya mpope mafuta mu magawo 5 kapena 7. Kuti muchite izi, muyenera kuyamba ndi fusesi ndikumaliza ndikuyang'ana kuthamanga. Kukhala ndi multimeter, kupima kuthamanga ndi batri yokhala ndi mawaya Werengani zambiri
