Kupisa Kutengesa Diesel Fuel Yakajairwa Rail Injector Nozzle G3S151 yeCommon Rail System Spare Parts

1. Kugadziriswa kwegungano kusina kunaka
Kutanga, kubvumidzwa pakati pehumburumbira nepiston hakuzadzise zvinodiwa, zvichikonzera kupinduka kwepiston mhete chinzvimbo, uye nzvimbo yekuvhura haina kudzedzereka, zvichiita kuti mafuta uye gasi kubuda mucylinder. Chechipiri, iyo huru shaft inotakura uye yekubatanidza tsvimbo inotakura inoiswa munzvimbo yakajairwa, zvichiita kuti nzvimbo yegungano isasangana nezvinodiwa, uye torque yekusimbisa uye kubvumidzwa hazvienderane nechiyero, zvichikonzera kupisa nekupfeka. Chechitatu, giya renguva rinoiswa munzvimbo yegungano, richikanganisa hukama hwemagetsi, uye zvichikonzera kudhumhana kwepiston nevhavha.
dambudziko. Chechina, iyo valve clearance haina kuenderana neyakajairwa, inokanganisa kusimba kwevhavha, iyo inogona kupisa vharafu uye zvimwe zvikamu, uye kukurumidza kupfeka kweiyo valve mechanism zvikamu. Chechishanu, kupihwa uye kupindirana kwecylinder yega yega hazvina kuenzana, izvo zvinogona kukanganisa nyore kugadzikana kweinjini yedhiziri uye kukonzeresa kusakwana kwekupisa matambudziko.
2. Injini yedhiziri haigoni kutanga zvakajairika
Kutanga, tarisa yakaderera-kudzvanywa mafuta dunhu. Ngwarira kutarisa switch yedhiziri pazasi petangi redhiziri kuti uone kuti iri munzvimbo yakavhurika. Shandisa vharafu yekudhonza kubvisa zvachose mafuta akasviba nemvura mutangi. Panguva imwecheteyo, tarisa uye ubvise mafuta akasviba nemvura musefa uye dizeli sefa. Iyo bleed screw pamusoro pepamusoro-yekumanikidza pombi muviri inofanira kusunungurwa zvakakodzera. Shandisa pombi yeoiri yeruoko kupomba oiri, uye tarisa iyo yakaderera-kudzvanywa kwemafuta ekupa panguva imwe chete kuti uone kuti yakakwana uye yakatsetseka. Kana isiri yakatsetseka uye isina kukwana, zvinoreva kuti kune mhepo yakasara mukati. Nyanzvi inofanirwa kutarisa zvese zvinongedzo zvepombi pamberi pepombi yeoiri yeruoko kuti itarise nzvimbo dziri kubuda. Kana pombi yemafuta yemaoko ichishandiswa kupomba mafuta, kana mafuta achinetsa kupinda uye kusveta kwemafuta kusina kutsvedzerera, zvinoreva kuti pane kuvharika mumhepo yakaderera-pressure yemafuta, uye dhiziri sefa yedhiziri, sefa chinhu. , uye kuvharika kwepombi kunofanirwa kutariswa. Kana tembiricha yadzikira, mhando yedhiziri inofanirwa kutariswa kudzivirira kuvharika kwemafuta nekuda kwekunaya kwedhiziri nemvura kutonhora. Kana dambudziko rekuvharika rikaitika, kukanganisa kunofanirwa kubviswa nenguva kusvika kusveta kwemafuta kwave kutsetseka uye mafuta anowanikwa asina mabhuru. Kana kukanganisa kusina kukonzerwa nezvikonzero zviri pamusoro apa, zvingave kuti piston yepombi yemafuta yemaoko yakasakara zvakanyanya, valve yakakuvadzwa, kana kuti yakasvibiswa nemagetsi netsvina. Inogonawo kunge yakakonzerwa nekusavharwa kwakakwana kwepombi yemafuta emaoko, uye pombi yemafuta yemaoko inoda kutsiviwa panguva ino. Chechipiri, tarisa high-pressure oil circuit. Kana pasina chikanganiso mumhepo yakaderera-inodzvinyirira, injini yedhiziri haigoni kutanga zvakajairika, uye mhepo yepamusoro-soro yemafuta inofanira kuongororwa. Chekutanga, tarisa iyo oiri huwandu hwekugadzirisa giya rodhi repamusoro-kudzvanywa pombi kuti ive nechokwadi chekuchinjika kwechigadziriso chegiya giya kuti irege kunamira panzvimbo yekumira. Teerera kutarisa nguva yekupihwa kwemafuta yepombi yemafuta ekudzvanya. Kana iyo nguva yekupa mafuta isinganzwisisike, inofanirwa kugadziridzwa kune yakatarwa nguva. Chenjerera kubvisa mhepo mukati mepombi yemafuta ekumanikidza. Kana paine mhepo mukati medhiziri yakakwira-kudzvanywa mafuta pombi, haigone kupfuura nepakati pekutangisa kutyaira injini yedhiziri kutenderera. Paunenge uchibata, nut inobatanidza jekiseni kune pombi yepamusoro yemafuta inofanira kusunungurwa, uye tangi inofanira kutangwa kutenderera injini yedizeli. Kana pombi yemafuta yakakwira-kudzvanya ichikwanisa kupfapfaidza mafuta, nati inobatanidza pombi yemafuta inodzvanywa inofanira kusimbiswa. Kana iyo nzira iri pamusoro isinga shandiswe kutanga, jekiseni uye pombi yemafuta epamusoro-soro inofanira kuongororwa. Hazvina mhosva kuti ndeipi yemidziyo iri pamusoro inotadza, kushanda kwekuyedza kunofanirwa kuitwa pabhenji rekuyedza, uye yakakosha yekumanikidza tester inofanirwa kushandiswa kudzivirira tsaona.
