Kukanganisa kwakajairika uye Mhinduro dzeFuel System yeJenareta Set

Iyo mafuta system yedhiziri jenareta seti ndiyo huru yepakati chikamu.Pamusoro pekupfeka kwekutanga kwezvitatu zvekubatanidza zvikamu zvehuti, izvo zvinotungamira mukudzikiswa kwesimba rejenareta, kuwedzera kwemafuta ekushandisa uye utsi hwekuburitsa, kune marudzi maviri ezvikanganiso zvinonyanya kuitika muhurongwa hwemafuta: imwe. imhosva inokonzerwa nekuiswa zvisina kunaka kwepombi jekiseni remafuta, uye imwe imhosva mukushandiswa.

A.Kutadza kukonzerwa nekugadzwa kusina kunaka kwepombi jekiseni remafuta re dhiziri jenareta set

1. Kiyi ye semicircular haina kuiswa panzvimbo

Yepombi yejekiseni yemafuta yakabatana neflange, kana nzvimbo yekuisa semicircular kiyi pakati pemafuta ekupa nguva yegiya uye otomatiki regulator yemafuta ekufambisa mberi angle uye camshaft yepombi jekiseni remafuta isiriyo, pachave nekusawirirana kwemafuta nguva. , injini yakaoma kutanga, utsi uye kupisa kwemvura yakakwirira.Kana isingakwanise kugadziridzwa kuburikidza nearc hole paflange, pombi yejekiseni yemafuta inoda kubviswa uye kuiswazve.Mushure mekubviswa, indentation iri pachena inogona kucherechedzwa pane semicircular kiyi.

2. Mafuta ekupinza uye zviputi zvekudzorera zvakaiswa zvisizvo

Kana uchibatanidza pombi yemafuta, kana mafuta ekudzosera screw akaiswa zvisizvo papombi yemafuta inopinza pombi yepombi jekiseni yepombi, nekuda kwechiito chevhavha yekutarisa muscrew yekudzosera mafuta, mafuta haakwanise kupinda kana kungopinda zvishoma. iyo mafuta inlet kamuri yepombi jekiseni remafuta, kuitira kuti dizeli jenareta seti haigone kutangwa kana kuti haigone kuwedzerwa mushure mekutanga kuwedzera kumhanya.Panguva ino, pombi yemaoko inopikisa kukuru kupomba mafuta, uye haigone kudzvanya pombi yemaoko.Panguva ino, kukanganisa kunogona kubviswa chero bedzi nzvimbo dzekuisa dzemafuta ekupinda uye kudzoka screws dzichitsinhaniswa.

B.Common kukanganisa mukushandiswa kwedhiziri jenareta set

1. Urombo husina kunaka hwekugovera kwepasi-kudzvanywa mafuta dunhu

Mapombi anopinza oiri uye anodzosera mapaipi ejenareta redhiziri akaiswa kubva mutangi reoiri kuenda kukamuri yekupinza oiri yepombi yejekiseni yemafuta ndeyekudzikira-kudzvanywa kwemafuta.Kana iyo pombi yakabatana, gasket nepombi yemafuta ichidonhedza oiri nekuda kwekukuvara, mhepo inopinda mudunhu remafuta kuti ibudise kupikisa kwemhepo, zvichikonzera kushaikwa kwemafuta, kuoma kweinjini kutanga, kumhanyisa kunonoka uye kumwe kukanganisa, uye yobva yazvivharira zvakakomba. nyaya.Kana iyo mhiri-chikamu nzvimbo yepombi yemafuta yadzikiswa nekuda kwekuchembera, deformation uye kusachena kuvharika, kana iyo mafuta sefa skrini uye dizeli sefa chinhu chakavharwa nekuda kwekusvibiswa kwemafuta, zvinokonzeresa kusakwana kwemafuta uye kuderedza simba reinjini. uye ita kuti zviome kutanga.Pombera mafuta kune imwe kudzvinyirirwa nepombi yemaoko uye sunungura siruu yemhepo.Kana pane mabhubhu achipfachukira uye kupera kusina kukwana nguva dzose, zvinoreva kuti dunhu remafuta rinozadzwa nemhepo.Kana pasina mabubbles, asi mafuta edhiziri akapfachukira kubva kubleeder screw, dunhu remafuta rakavharwa.Chiitiko chakajairika ndechekusunungura zvishoma mhepo yakavhurika screw uye nekukasira kunze koramu yemafuta neimwe kumanikidza.Nzira yekugadzirisa matambudziko ndeyekutsvaga yakakuvara kana kuchembera gasket, yejoini kana mafuta pombi woitsiva.Nzira yekudzivirira kukanganisa kwakadai ndeyekuchenesa mafuta inlet sefa sikirini uye dizeli sefa chinhu kazhinji, tarisa pombi nguva zhinji, uye kugadzirisa matambudziko nenguva paanowanikwa.

2. Piston yepombi yekutakura mafuta yakaputsika

Iyo dhiziri jenareta yakangoerekana yamira panguva yekushanda uye haigone kutangwa.Sunungura siruu inobuda ropa uye tarisa kuti kana pasina kana mafuta mashoma mukamuri yepombi yejekiseni yemafuta yakaderera, pomba mafuta nepombi yeruoko kusvikira kamuri yese yemafuta yazara nemafuta, yapedza mweya. uye wotangazve injini.Injini inodzokera kune yakajairika, asi inozodzima zvakare mushure mekutyaira kweimwe chinhambwe.Ichi chinokanganisa chiitiko chinogona kunge chiri chekuti piston chitubu chepombi yekufambisa oiri yakatyoka.Mhosva iyi inogona kubviswa zvakananga.Vhura sikuruu wotsiva chitubu.

3. Ivhavha yekuongorora yepombi yekufambisa mafuta haina kuvharwa zvakasimba

Iyo dhiziri jenareta seti inoshanda zvakajairika mushure mekutanga, asi zvakaoma kutanga mushure mekudzima kweimwe nguva.Pane bubble rinofashukira pakusunungura siruu ye vent.Inogona kutangwa chete mushure mekunge mhepo yapera zvakare.Kukanganisa uku kunonyanya kukonzerwa nekuvharwa kwakasununguka kwevhavha yekutarisa yepombi yekufambisa mafuta.Nzira yekuongorora ndeyekusunungura sikuruu yekubuda kweoiri yepombi yekuburitsa oiri uye kupomba pombi yeoiri kuzadza mhango yemafuta yejoini yekubudisira mafuta.Kana chiyero chemafuta mumubatanidzwa chinodonha nekukurumidza, chinoratidza kuti cheki chevhavha haina kuvharwa zvakanaka.Bvisa cheki valve uye tarisa kana chisimbiso chakasimba, kana cheki chevhavhavha chitubu chakatyoka kana kuremara, uye kana paine kusvibiswa kusiri pachigaro chekuvhara.Zvinoenderana nemamiriro ezvinhu chaiwo, kugaya nzvimbo yekuisa chisimbiso uye kutsiva cheki vharafu kana cheki chevhavha chitubu kuti ubvise kukanganisa.Kazhinji, mwero weoiri haudonhe mukati meanopfuura maminetsi matatu, uye mbiru yeoiri yepombi inoburitswa zvine simba kubva pajoinhi yemafuta.

4. High pressure oil pipe yakavharwa

Kana iyo pombi yemafuta ekudzvanya kwecylinder yakavharika nekuda kwedeformation kana tsvina, panogona kunge paine ruzha rwekugogodza kuri pachena papombi yemafuta mushure mekutanga. Yuchai dizeli jenareta , uye simba rejenareta redhiziri rinoderera nokuti cylinder haigoni kushanda zvakanaka.Nzira yekuongorora ndeyekusunungura nati pamucheto weoiri inopinza yeakakwira-kumanikidza mafuta pombi cylinder necylinder.Kana ruzha rwekugogodza rwunonyangarika mushure mekusunungura silinda, zvinogona kugumiswa kuti cylinder ivhavha yakashata, uye kukanganisa kunogona kubviswa mushure mekutsiva pombi yemafuta.

5. Fuel injector coupling yakanamatira

Kana jekiseni revharuvhu rakanamira panzvimbo yakavharwa, pane inonzwika kugogodza nguva dzose pedyo nemusoro wecylinder.Izvo zvinokonzerwa nekukanganiswa kwemhepo yekumanikidza yepombi jekiseni remafuta pane jekiseni remafuta.Nzira yekutonga ndeyekusunungura pombi yepamusoro yemafuta yakabatanidzwa kune injector yekupedzisira.Kana ruzha rwekugogodza rukanyangarika pakarepo, zvinogona kugumiswa kuti vheji yetsono yeinjector yecylinder iyi yakanamatira.
