Chengetedzo Yekuchengetedza Yekudzvanyirira Yepamusoro Yakajairwa Rail Diesel Jenareta

Cummins dhiziri inogadzira jenareta inokudzidzisa ruzivo rwekugadzirisa: matanho ekuchengetedza epamusoro voltage common rail dhiziri jenareta.

1. Kushandiswa kwezuva nezuva

Iyo yakakwira-kumanikidza yakajairika njanji dizeli jenareta inowanzo shongedzerwa preheater.Kana yatangwa pasi peyakadzika tembiricha nharaunda, iyo preheating switch inogona kuvhurwa kutanga.Kana mwenje wepreheater wabatidzwa, zvinoratidza kuti preheater inotanga kushanda.Mushure menguva yekupisa, jenareta yedhiziri inogona kutangwa mushure mekunge chiratidzo chekupisa chadzimwa.Iyo preheating chiratidzo zvakare ine alarm basa.Kana iyo preheating chiratidzo ichipenya panguva yekushanda kweyakajairika njanji dizeli jenareta, inoratidza kuti iyo dhiziri jenareta control system yakundikana uye inofanirwa kugadziriswa nekukurumidza sezvinobvira.

Usashandise yakakwira-kudzvanya mvura kutsvaira iyo jekiseni jekiseni rejenareta rejanji njanji, nekuti mushure mekunge mvura yapinda mumagetsi ekudzora unit, sensor, actuator uye chinongedzo chayo, chinobatanidza chinowanzo marara, zvichikonzera "kukanganisa kupfava" ndiko. zvakaoma kuwana mune zvemagetsi control system.

Iyo yemagetsi control unit, sensor uye actuator ye-high-voltage yakajairika njanji dizeli jenareta inonyanya kunzwira voltage.Kunyangwe kana bhatiri iine simba shoma shoma, inokanganisa kushanda kwakajairika kwemagetsi ekudzora system.Naizvozvo, zvinodikanwa kuchengetedza simba rekuchengetedza rebhatiri rakakwana.Kana welding kugadziriswa kunoitwa pane yakakwirira-voltage yakajairika njanji dizeli jenareta, tambo yebhatiri inofanirwa kuparadzaniswa, chinongedzo cheECU chinofanira kubviswa, uye zviri nani kubvisa chaiyo yemagetsi control unit.Electronic control units, sensors, relays, nezvimwe zvinhu zvakaderera-voltage, uye overvoltage inogadzirwa panguva yewelding iri nyore kwazvo kupisa zviri pamusoro apa zvigadzirwa zvemagetsi.

Mukuwedzera, kuvhiyiwa kunotevera kunogona kuitwa chete mushure mokunge dhiziri yepamusoro-soro yejenareta yedhiziri yakavharwa kweinenge 5min, kuitira kudzivirira kukuvara kwemunhu kunokonzerwa ne-high-pressure fuel injection.

2. Kuchenesa matanho

High pressure common rail dhiziri jenareta ine zvakaomesesa zvinodiwa zvezvigadzirwa zveoiri, uye zvirimo zvesarufa, phosphorus uye tsvina zvakaderera.Mafuta edhiziri emhando yepamusoro uye mafuta einjini anofanira kushandiswa.Mafuta edhiziri asina kunaka ari nyore kukonzeresa kuvharika uye kupfeka zvisina kujairika kwemajekiseni emafuta.Naizvozvo, zvinodikanwa kugara uchidonhedza mvura uye sediment mumafuta-mvura separator, uye kugara uchichenesa kana kutsiva dizeli sefa nemafuta sefa.Tichifunga nezvekuti mhando yedhiziri inoshandiswa nemaseti ejenareta edzimba yakaoma kuzadzisa zvizere zvinodikanwa zveyakanyanya kudzvanywa njanji yedhiziri jenareta, zvinokurudzirwa kushandisa yakasarudzika dizeli ekuwedzera kune tangi yemafuta uye kuchenesa mafuta ekufambisa. system nguva dzose.

Usati wabvisa jekiseni remafuta, kana kana muromo wemafuta jekiseni system zvikamu (senge jekiseni remafuta, pombi yekutakura mafuta, nezvimwewo) ikawanikwa yakasvibiswa neguruva, zvinokurudzirwa kushandisa guruva rekudhonza guruva kuti ritore guruva rakatenderedza. , uye usashandise high-pressure gasi kufuridza, high-pressure water flushing kana ultrasonic cleaning.

Iyo yekugadziridza jenareta seti kamuri uye maturusi anofanirwa kuchengetwa akachena zvakanyanya kudzivirira kuunganidzwa kweguruva.Mukamuri yekugadzika jenareta, zvimedu uye fiber zvinosvibisa iyo jekiseni jekiseni system hazvibvumirwe, uye michina yekushingisa, michina yekukuya uye zvimwe zvigadzirwa zvinogona kusvibisa jekiseni remafuta hazvibvumidzwe.

Mbatya dzevanogadzirisa dzinofanira kunge dzakachena, uye hazvibvumidzwe kutakura huruva nemachipisi esimbi.Izvo hazvibvumidzwe kupfeka zvipfeko zvine fluffy kudzivirira kusvibisa jekiseni remafuta.Geza maoko pamberi pekugadzirisa kushanda.Kusvuta uye kudya kunorambidzwa zvachose panguva yekushanda.

3. Disassembly, kuchengetedza uye kutakura kwezvikamu.

Mushure meiyo high-pressure common rail dhiziri inogadzira seti inomhanya, zvinorambidzwa kuparadzanisa iyo yakakwirira-kumanikidza yakajairika jekiseni renjanji.Paunenge uchibvisa kana kuisa pombi yekudzosa oiri yepombi yemafuta ekudzvanya, manikidza uchitevedza axial nzira kudzivirira kukotama.Imwe neimwe nati ichasimbiswa kune yakatsanangurwa torque uye haizokuvadzwa.Mushure mekunge dhizaini yekupa mafuta yabviswa, kunyangwe nguva yacho iri pfupi kwazvo, chivharo chakachena chekudzivirira chinofanira kupfekwa nekukasira, uye chivharo chekudzivirira chinogona kubviswa chisati chasangana zvakare.Zvishandiso zveyakakwirira-kudzvanywa zvakajairika jekiseni renjanji zvinofanirwa kuvhurwa zvisati zvashandiswa, uye kepisi yekudzivirira inofanira kubviswa isati yaungana.

Paunenge uchichengetedza uye uchitakura majenareta ejenareta ejenareta, iyo jenareta yemafuta, high-pressure oil pump assembly, mafuta enjanji uye zvimwe zvikamu zvejekiseni zvinofanira kupfeka zvivharo zvekudzivirira, uye jekiseni remafuta richaputirwa nepepa remafuta.Zvikamu zvichadzivirirwa kubva pakudhumhana panguva yekufambisa.Pakutora nekuaisa, anogona kungobata muviri wezvikamu.Zvinorambidzwa kubata majoini epombi yekupinza uye yekubuda neoiri uye maburi emuromo wejekiseni remafuta, kuitira kuti udzivise kusvibisa iyo yakanyanya-kumanikidza yakajairika jekiseni renjanji.
