Kuwonongeka kwa makina a Volvo excavator nthawi zambiri kumagwera m'magulu awa:
1. Kachitidwe ka injini
- Kuvuta Kwambiri / Kuyimitsa Kwapang'onopang'ono: Izi zitha kuchitika chifukwa cha sensor yolakwika ya camshaft (mwachitsanzo, ingress yamadzi kapena okosijeni mu cholumikizira), nkhani zoyambira zoyambira (palibe yankho kuchokera ku injini yoyambira, mphamvu yamagetsi yosadziwika bwino), kapena kusakwanira kwamafuta a dizilo (zosefera zotsekeka zamafuta, atomization yamafuta osakwanira).
- Kutha Kwa Mphamvu: Amadziwika ndi kukumba kofooka komanso utsi wotopa kwambiri. Zomwe zingayambitse zimaphatikizapo majekeseni otha mafuta, zosefera mpweya wotsekeka, kapena kuvala kwa injini yamkati (mwachitsanzo, kuyatsa mafuta).
- Kutentha kwa injini: Zomwe zimayambitsa ndi kutayikira kwa ma radiator, kulephera kwa pampu yamadzi, kapena kutsekeka munjira yozizirira.
2. Hydraulic System
- Zoyenda Pang'onopang'ono / Zofooka: Izi zitha kuchitika chifukwa cha kuvala kwa pampu ya hydraulic, kutayikira mu valavu yowongolera (valavu yogawa), kapena zisindikizo zamafuta okalamba papaipi yapakati.
- Nkhani Zapaulendo: Kuyenda mofooka kumbali imodzi kapena kugwedezeka nthawi zambiri kumakhudzana ndi zovuta zamagalimoto oyenda, kuthamanga kwa njanji, kapena kuwonongeka kwa ma hydraulic valve.
- Kutuluka kwa Mafuta: Nthawi zambiri zimachitika chifukwa cha kukalamba kwa zisindikizo zamafuta a silinda kapena mapaipi owonongeka.
3. Njira yamagetsi
- Palibe Choyambira: Yang'anani ma fuse, ma relay, ndi maulumikizidwe a ECU (Electronic Control Unit) kuti atayike.
- Yang'anira Zolakwika Zowonetsera: Zitha kuchitika chifukwa cha kusakhazikika kwamagetsi kapena kulephera kwa sensa.
4. Zolakwa Zinanso
- Kuthamanga kwa Mafuta Ochepa: Yang'anani mulingo wamafuta, fyuluta yamafuta, ndi mpope wamafuta.
- Zosefera Zotsekeka: Kutsekeka mumlengalenga kapena zosefera zamafuta kumabweretsa kuchepa kwa makina.
- Kuyimirira Pansi Pakatundu: Izi zitha kuchitika chifukwa cha kulephera kwa ECU, kulephera kwa ma valve a solenoid, kapena mafuta a dizilo osakwanira bwino.
Malangizo
Ndibwino kugwiritsa ntchito zida zowunikira kuti muwerenge zolakwika (mwachitsanzo, kudzera pa VECU dongosolo) kuti muthandize kuthetsa mavuto. Kuonjezera apo, sinthani zinthu zomwe zimagwiritsidwa ntchito nthawi zonse (monga zosefera ndi zosindikizira zamafuta) kuti muchepetse kuwonongeka. Pazovuta zovuta, chonde tsatirani njira yathu yovomerezeka kuti mumve zambiri kapena funsani katswiri wodziwa ntchito yake.
Zongotchula chabe.
