Sumo pfupi yepombi yemafuta

Pombi yeoiri pombi yakareruka uye yakabatana, ine zvikamu zvitatu: mu-mutsetse, wakagoverwa uye{1}}muviri mumwe. Pombi yemafuta inoda sosi yemagetsi kuti ishande, uye camshaft iri pazasi payo inofambiswa neinjini crankshaft giya.
Pombi yemafuta inokurudzira pombi yeoiri ine imba yakagadzirwa nealuminium{{0}iine zvinhu uye chikamu chinofambika chakarongwa mudzimba, umo chinoumbwa chinofambiswa chinoitwa zvishoma nesimbi inopinza{1}based alloy material ine kana imwe austenite, uye umo chikamu chakaumbwa chinogadzirwa nechidimbu chechinhu chinotambanuka % thermal kuwedzera coefficient yeimba.
Chikamu chakakosha chepombi jekiseni remafuta ndiyo plunger. Kana sirinji yakajairika muchipatara ichishandiswa semuenzaniso, ipapo plug inofambiswa inonzi plunger, uye sirinji inonzi plunger sleeve. Tichifunga kuti chitubu chakaiswa mujekiseni kutsigira imwe mugumo weplunger, uye imwe magumo eplunger inobata camshaft, kana camshaft ichitenderedza denderedzwa rimwe, plunger inokwira nekudzika kamwe mune plunger sleeve. Iyi ndiyo nzira yekutanga yekufambisa yeplunger yepombi jekiseni remafuta.
Iyo plunger uye sleeve yeplunger zvakanyatsogadziriswa zvikamu zvinoenderana. Pane mugero wakarerekera pane plunger, uye buri diki paruoko rwe plunger rinonzi suction port. Chiteshi chekukweva ichi chakazadzwa nedhiziri. Kana plunger inclined groove yakatarisana nechiteshi chekukweva, dhiziri inopinda muruoko rweplunger. Apo plunger inosundirwa kune imwe nzvimbo yakakwirira necamshaft, plunger inclined groove inozununguka nechiteshi chekusveta, uye chiteshi chekukwevera chinovharwa, kuitira kuti dhiziri irege kusvetwa mukati kana kudzvanywa. Apo plunger inoramba ichikwira, inodzvanya dhiziri. Kana dhiziri yasvika pane imwe nhanho, inosaidzira kuvhura imwe-vharuvhu yobva yamhanya ichibuda mumuromo wejekiseni remafuta, yobva yapinda mukamuri rinopisa humburumbira kubva pamuburi wejekiseni remafuta. Nguva imwe neimwe iyo plunger inoburitsa imwe huwandu hwedhiziri, chikamu chayo chete chinopfapfaidzwa mucylinder, uye imwe yese inoburitswa kubva mugomba remafuta ekudzoka, uye huwandu hwejekiseni hunogadziriswa nekuwedzera kana kudzikisa huwandu hwemafuta ekudzoka akadeuka. Kana plunger yasimuka ichienda ku "kumusoro" uye ichidzika pasi, iyo plunger inclined groove inosangana nechiteshi chekukwevera zvakare, uye dhiziri inosvetwa muruzha rweplunger zvakare, ichidzokorora chiito chiri pamusoro zvakare. Boka rega rega remaplunger masitamu epombi-muline jekiseni remafuta rinoenderana necylinder imwe chete, uye kune 4 mapoka emaplunger masitaini emasilinda mana, saka vhoriyamu yacho ihombe, uye inonyanya kushandiswa mumotokari dzakakura zviripakati nepakati-ne hombe. Semuyenzaniso, injini dzedhiziri mumabhazi nemarori dzinowanzoshandisa-mumajekiseni epombi.
