Diesel engine fuel pressure ichave yakadzikira kana kusamanikidzwa nekuda kwekupfeka kwezvikamu zveinjini, kusangana kwakashata kana kumwe kukanganisa. Kukanganisa senge yakawandisa mafuta kudzvanywa kana oscillating pointer yekumanikidza geji. Somugumisiro, tsaona dzinoitika mukushandiswa kwemichina yokuvaka, zvichiguma nokurasikirwa kusiri madikanwa.
1. Kuderera kwemafuta kuderera
Kana kudzvinyirirwa kunoratidzwa nemafuta ekumanikidza gauge kunowanikwa kuderera pane yakajairika kukosha (0.15-0.4 MPa), mira muchina nekukurumidza. Mushure mekumirira 3-5 maminetsi, buritsa gauge yemafuta kuti utarise kunaka uye huwandu hwemafuta. Kana huwandu hwemafuta husina kukwana, hunofanira kuwedzerwa. Kana iyo viscosity yemafuta yakaderera, huwandu hwemafuta hunokwira uye kunhuhwirira kwemafuta kunoitika, mafuta anosanganiswa nemafuta. Kana mafuta akachena semukaka, imvura yakasanganiswa muhuni. Tarisa uye bvisa mafuta kana kubuda kwemvura uye wotsiva mafuta sezvinodiwa. Kana mafuta akasangana nezvinodiwa zverudzi urwu rweinjini yedhiziri uye huwandu hwakakwana, sunungura screw plug yenzira huru yemafuta uye shandura crankshaft. Kana mamwe mafuta akadzimwa, kubvumidzwa kwekubatana kweiyo huru, yekubatanidza tsvimbo inotakura uye camshaft inotakura inogona kunge yakakura kwazvo. Iyo yekubereka clearance inofanira kuongororwa uye kugadziriswa. Kana paine mafuta mashoma anobuda, anogona kuvharika sefa, kuvuza kwevhavha inodzikamisa vharafu kana kurongeka kusina kunaka. Panguva ino, iyo sefa inofanirwa kucheneswa kana kutariswa uye iyo yekumanikidza inomisa valve inogadziriswa. Kugadziriswa kwevhavha inomisa kumanikidza kunofanirwa kuitwa pachigadziko chekuyedza uye haifanirwe kuitwa pamadiro. Mukuwedzera, kana pombi yemafuta yakasakara zvakanyanya kana kuti chisimbiso gasket chikakuvadzwa, zvichiita kuti pombi yemafuta irege kupomba mafuta, ichaitawo kuti kudzvinyirira kwemafuta kuve kwakaderera. Panguva ino, zvakakosha kutarisa uye kugadzirisa pombi yemafuta. Kana pasina kukanganiswa kunowanikwa mushure mekutarisa pamusoro, zvinoreva kuti gauji yehutsi hwemafuta haisi kurongeka uye gauji nyowani yekumanikidza mafuta inoda kutsiviwa.
2. Hapana mafuta anomanikidza
Munguva yekushanda kwemichina yekuvaka, kana chiratidzo chemafuta chichivhenekera uye cheji yekumanikidza gauge pointer inonongedza ku0, muchina unofanirwa kumiswa nekukasira uye moto unofanirwa kumiswa. Wobva watarisa kana pombi yemafuta ichibvinza zvakanyanya nekuda kwekutsemuka nekumwe kamwe. Kana kunze kweinjini pasina kubvinza kukuru kwemafuta, sunungura kubatanidzwa kwegeji yemafuta. Kana mafuta akabuda nekukurumidza, gauge yemafuta inokanganiswa. Sezvo sefa yemafuta yakaiswa pahumburumbira, panofanira kazhinji kuve nebepa cushion. Kana iyo cushion yepepa isina kuiswa zvisina kunaka kana gomba rekupinza mafuta rakabatana negomba remafuta enyika, mafuta haagone kupinda mugero remafuta. Izvi zvine njodzi, kunyanya kune injini yedhiziri ichangobva kuvandudzwa. Kana pasina chiitiko chisina kujairika chinowanikwa kuburikidza nemacheki ari pamusoro, kukanganisa kunogona kunge kuri papombi yemafuta uye pombi yemafuta inoda kuongororwa nekugadzirisa.
3. Kuwedzerwa kwemafuta kudzvinyirira
Munguva yechando, kana injini yedhiziri ichangotanga, zvichaonekwa kuti kudzvinyirira kwemafuta kuri kumusoro uye kunodonha kune yakajairika mushure mekupisa. Kana iyo yakaratidzwa kukosha kwemafuta ekumanikidza gauge ichiri kudarika kukosha kwakajairika, iyo yekumanikidza inomisa vharafu inofanirwa kugadziridzwa kuti isangane neiyo kukosha kwakatarwa. Mushure mekutumwa, kana kudzvanywa kwemafuta kuchiri kwakanyanya, mhando yemafuta inoda kutariswa kuti uone kana mafuta emafuta akanyanya kukwira. Kana mafuta acho asina viscous, zvingave kuti dhizaini yekuzora yakavharwa uye inocheneswa nemafuta edhiziri akachena. Nekuda kwekushomeka kwakashata kwemafuta edhiziri, zvinongokwanisika kutenderedza tangi ne crankshaft kwemaminitsi 3-4 panguva yekuchenesa (ona kuti injini haifanire kutangwa). Kana injini ichifanira kutangwa pakuchenesa, inogona kucheneswa mushure mekusanganisa 2/3 yemafuta uye 1/3 yemafuta kweasingapfuuri maminetsi matatu.
4. Mucherechedzo wemafuta ekumanikidza geji oscillates kumashure uye mberi
Mushure mekutanga injini yedhiziri, kana iyo pointer yemafuta ekumanikidza gauge oscillates kumashure uye mberi, geji yemafuta inofanira kuburitswa kunze kutanga kutarisa kana mafuta akakwana, uye kana zvisina kudaro, mafuta akakodzera anofanira kuwedzerwa maererano nechiyero. The bypass valve inofanira kuongororwa kana pane mafuta akakwana. Kana iyo bypass valve chitubu chakaremara kana isina kukwana elasticity, iyo bypass valve spring inofanira kutsiviwa; Kana iyo bypass valve isingavhare zvakanaka, inofanira kugadziriswa
