Volvo excavator malfunctions inowira muzvikamu zvinotevera:
1. Engine System
- Zvakaoma Kutanga / Kumira Kwepakati: Izvi zvinogona kukonzerwa nechakaipa camshaft sensor (semuenzaniso, mvura ingress kana oxidation mukubatanidza), starter circuit nyaya (hapana mhinduro kubva kune starter motor, abnormal key power supply), kana kusakwana kwedizeli mafuta ekufambisa (akavharwa mafirita emafuta, asina kunaka mafuta injector atomization).
- Kupera Simba: Inoratidzwa nekuchera kusina simba kwekuita uye yakanyanyisa kuputa utsi. Zvikonzero zvinogona zvinosanganisira majekiseni emafuta akasakara, sefa yemhepo yakavharwa, kana kupfeka injini yemukati (semuenzaniso, kupisa mafuta).
- Engine Overheating: Zvinowanzokonzeresa kudonha kweradiator, kutadza kwepombi yemvura, kana kuvharika muhurongwa hwekutonhodza.
2. Hydraulic System
- Mafambiro Anononoka / Asina Kusimba: Izvi zvinogona kuguma nekupfeka kwe hydraulic pombi, kuvuza muvharuvhu yekudzora (vharuvhu yekuparadzira), kana zvisimbiso zvemafuta ekuchembera mupombi yepakati.
- Nyaya dzekufamba: Kufamba kusina kusimba kune rimwe divi kana kudhiraivha kunowanzoenderana nezvinetso nemota yekufambisa, tension yetrack, kana hydraulic valve malfunctions.
- Oiri Inobuda: Zvinowanzoitika nekuda kwekuchembera silinda mafuta zvisimbiso kana kukuvadzwa mapaipi.
3. Electrical System
- Hapana Kutanga: Ongorora ma fuse, relay, uye zvinongedzo kuECU (Electronic Control Unit) kuti zviite sei.
- Monitor Display Abnormalities: Inogona kukonzerwa nekusagadzikana kwemagetsi kana sensor kutadza.
4. Zvimwe Zvinowanzokanganisa
- Low Oil Pressure: Tarisa huwandu hwemafuta, sefa yemafuta, uye pombi yemafuta.
- Masefa Akavharwa: Kuvharika mumhepo kana mafirita emafuta kunotungamira mukudzikira kwekuita kwemuchina.
- Kumira Pakuremerwa: Izvi zvinogona kukonzerwa nekusashanda zvakanaka kweECU, kutadza kwevharuvhu ye solenoid, kana kuti mafuta edhiziri asina kunaka.
Recommendations
Zvinokurudzirwa kushandisa maturusi ekuongorora kuti uverenge zvikanganiso (semuenzaniso, kuburikidza neVECU system) kubatsira mukugadzirisa matambudziko. Pamusoro pezvo, gara uchitsiva zvikamu zvinodyiwa (senge mafirita uye zvisimbiso zvemafuta) kuderedza kuparara. Nezvezvinhu zvakaoma, ndapota tevera chiteshi chedu chepamutemo kuti uwane zvigadziriso kana kubvunza nyanzvi ine hunyanzvi.
Zvekutaura chete.
