0042 Cholumikizira Chosindikizidwa LPG CNG M'malo mwa Solenoid Coil

Chovala cha valve solenoid ndi 29mm kutalika ndi 9mm m'mimba mwake mkati.
1. Zoyenera kuyang'anira zidutswa za koyilo yopopera njanji: Onani ngati mpweya watsikira pa muzu wa mawaya komanso ngati kulimba kwa ma koyilo anayiwo kuli pakati pa 9 ndi 3 ohms.

Chachiwiri, chinthucho chimakutidwa ndi zida za thermoplastic kapena retardant lawi komanso utomoni wosamva kutentha kwambiri, womwe umakhala ndi kukana kutentha kwambiri komanso kukana chinyezi. Amagwiritsidwa ntchito kwambiri pagalimoto yapawiri-mafuta LPG/CNG refitting system, njanji wamba yamafuta, chipangizo cha njinga yamoto, ndi zomwe zimagwiritsidwa ntchito nthawi zambiri voteji resistor DC12V.

III: ① Mapangidwe ndi magawo aukadaulo a jekeseni wamba wanjanji

1, mawonekedwe a mawonekedwe

Amagwiritsidwa ntchito kwambiri popanga majekeseni amafuta agalimoto zamagalimoto, omwe amatha kuzindikira mitundu itatu ya jakisoni: jakisoni isanachitike, jekeseni wamkulu komanso jekeseni wapambuyo. Kuchuluka kwa jakisoni wamafuta ndi kutalika kwa jakisoni wamafuta kumatsimikiziridwa ndi kukakamiza kwa dongosolo ndi mphamvu pa nthawi, ndipo zimayendetsedwa ndi gawo lowongolera zamagetsi. Pakalipano, majekeseni a galimoto yamalonda ali makamaka m'njira zotsatirazi;

2. Main luso magawo

Kukana kwa coil: 230mΩ

Kugwiritsa ntchito nthawi yayitali: 4ms

Kuthamanga kwakukulu kwa njanji yogwira ntchito: 1600bar

② Mfundo yogwiritsira ntchito jekeseni wamba wanjanji

mfundo ya ntchito

Yothimitsa (palibe jekeseni) => Yatsegula (jakisoni yayamba) => Kutsegula kwathunthu (jekeseni) => Kuchotsa (kuchepa kwa jekeseni) => Kutseka kwathunthu (kusiya jekeseni)

③ Kulephera kofala kwa majekeseni a njanji wamba ndi njira zawo zakusalana.

1. Internal dzimbiri mafuta

zizindikiro za njectorFault: injini imagwira ntchito mwamwano, ndipo utsi wakuda umatuluka powonjezera chitseko;

Chifukwa cholephera: madzi ochuluka mumafuta;

Yankho: 1. Onetsetsani kuti mafuta ali abwino; 2. Kukhetsa madzi nthawi zonse ndikuwonetsetsa kuti cholekanitsa madzi amafuta ndi abwino;

2. Mpando wamkati wa jekeseni wavala.

Chochitika cholakwika: kuwala kolakwika kumayaka, utsi wakuda umatulutsa pamene chitseko cha gasi chadzazidwa, ndipo mphamvuyo sikwanira;

Chifukwa cha kulephera: mafuta ali ndi chiwerengero chachikulu cha particles zabwino;

Yankho: Onetsetsani kuti fyulutayo ndi yabwino, makamaka kusefera kwabwino. Ikani chipangizo chosefera pabowo la thanki yamafuta kuti mupewe chilengedwe chakunja kuti zisawononge mafuta ndikuwonetsetsa kuti mafuta ali abwino.

3, mkuwa gasket chisindikizo si zabwino, yamphamvu mpweya ngalande.

Zizindikiro zolakwika: mphamvu ya injini yosakwanira, mpweya woyaka moto womwe umathawira mumafuta obwerera;

Chifukwa cholephera: gasket yamkuwa idamizidwa ndi tinthu tating'ono ndipo sitingathe kusindikizidwa;

Yankho: Onetsetsani ukhondo wa gasket yamkuwa, dzenje loyika injini ndi jekeseni poyika jekeseni.

Gasket yamkuwa singagwiritsidwenso ntchito. Bosch amalimbikitsa kugwiritsa ntchito gasket imodzi yokha yamkuwa kuti musagwiritse ntchito ma gaskets angapo.

4, ma electromagnetic valve electromagnetic coil kusungunuka

Chizindikiro cholakwa: jekeseni sangathe kugwira ntchito bwino;

Chifukwa cha kulephera: koyilo ya valve solenoid imasungunuka chifukwa champhamvu kwambiri pamagetsi kapena mphamvu yayitali kwambiri pa nthawi;

Yankho: Ndikoletsedwa kupatsa mphamvu jekeseni wamafuta mwachinyengo;

5, kuwonongeka kwa makina opangidwa ndi anthu

Chizindikiro cholakwa: Injector sigwira ntchito bwino chifukwa cha kuwonongeka kwa makina, ndipo injini ndi yosakhazikika.

Chifukwa cholephera: kugwira ntchito molakwika ndi kukhazikitsa kosamveka.

Yankho: 1. Limbani kapu ya solenoid valve, terminal ndi pulagi ya mtolo kuti musagwire ntchito movutikira; 2. Ikani jekeseni wamafuta motsatira buku la malangizo;

IV: Chithunzi chojambula cha solenoid valve common rail injector
. Valavu yamakono yowongolera solenoid imakopa zida, ndipo zida zimayendetsa tsinde la valavu ndi valavu ya singano kuti mutsegule jekeseni wamafuta kuti muyike mafuta.

Chifukwa chake, kuwongolera jekeseni wamafuta ndikuwongolera valavu ya solenoid ya jekeseni wamafuta. Valavu ya solenoid ndi yofanana ndi koyilo, yomwe imapanga mphamvu yamagetsi yamagetsi podutsa pano kudzera pa koyilo. Kuchuluka kwamakono, kumapangitsanso mphamvu yamaginito yamagetsi mpaka zidazo zitha kukopeka. Pogwiritsira ntchito, jekeseni nthawi zambiri imatsegulidwa ndi mphamvu yaikulu yoyamba, ndiyeno valavu ya solenoid imasungidwa ndi mphamvu yochepa.
