Kuchengetedza nzira dzeinjini yedhiziri jekiseni pombi

(5) Tarisa camshaft clearance nguva dzose
Iyo axial clearance yecamshaft yepombi jekiseni remafuta yakasimba kwazvo, kazhinji iri pakati pe0.03 ne0.15mm. Kana iyo clearance yakanyanya kukura, kukanganisa kweiyo roller transmission parts pane yekushanda pamusoro pekamera kuchawedzerwa, nekudaro ichiwedzera kupfeka kwekutanga kwekamera uye kushandura Oil supply advance angle; yakawandisa axial uye radial clearances yecamshaft mabearings anogona nyore kuita kuti camshaft imhanye zvisina kugadzikana, iyo oiri yehuwandu inogadzirisa tsvimbo kuti ichinje, uye huwandu hwemafuta hunochinja nguva nenguva, zvichiita kuti injini yedhiziri ishande isina kugadzikana. Naizvozvo, zvinodikanwa kuti utarise nguva dzose uye Kugadzirisa. Kana iyo axial clearance yecamshaft yakakura kwazvo, inogona kugadziriswa nekuwedzera shims kumativi maviri; kana iyo radial clearance yakakura kwazvo, zvinowanzodikanwa kuitsiva neitsva.

(6) Gara uchitarisa chimiro chekuisa chisimbiso chemusangano wevharuvhu weoiri pamushini
Mushure mekunge pombi jekiseni remafuta rave kushanda kwenguva yakati rebei, mutongo wakashata unogona kuitwa pakupfeka kweplunger uye mamiriro ekushanda epombi yemafuta nekutarisa kuvharwa kwevhavha yekubuda kwemafuta, iyo inobatsira kuona. nzira dzekugadzirisa uye kugadzirisa. Panguva yekuongorora, sunungura majoini epombi yemafuta ekudzvanya kwecylinder yega yega, uye pombi yemafuta nepombi yemafuta yemaoko yepombi yekuunza oiri. Kana paine mafuta anoyerera achibuda mupombi yemafuta majoini pamusoro pepombi jekiseni remafuta, zvinoreva kuti vharuvhu yekuburitsa mafuta haina kuvharwa zvakanaka (zvechokwadi, ichakuvadzwawo kana chitubu chevharuvhu yemafuta chaputswa. chiitiko chinoitika). Kana paine kusavharika kwakashata kwemasilinda akawanda, pombi yejekiseni yemafuta inofanirwa kunyatsogadziriswa uye kuchengetedzwa, uye kunyange zvikamu zvinofanirwa kutsiviwa.
