Nantsi isethi yeendlela zokuxilonga ezisebenzayo ezisetyenziswa ngabanini bomatshini kunye nabachwephesha bokulungisa, ukuvumela uvavanyo olunzima-ngaphandle kwezixhobo zobuchwephesha-ukuba i-excavator's electronic control unit (ECU) iyalungiswa okanye kufuneka itshintshwe.
I. Okokuqala Ukulawula Iimpazamo ezingezizo eze-ECU
Iimpawu ezininzi ezifana nokungaphumeleli kwe-ECU ngokwenene yimiba yangaphandle. Yenza olu hlolo kuqala:
Ngaba amandla ombane ebhetri aqhelekile?
Ukuba i-voltage yehla ngaphantsi kwe-21V ngexesha lokuqalisa, i-ECU inokubangela ii-alamu zobuxoki, ihluleke ukuqala, okanye ivale injini.
Ngaba ireyizi engundoqo okanye iifusi ziyavuthelwa?
Unikezelo lwamandla olungazinzanga kwi-ECU ngowona mba uxhaphakileyo.
Ngaba izihlanganisi zonakaliswe ngamanzi, zidliwe, okanye zikhululekile?
Zikhuphe kwaye ujonge ukufuma okanye i-oxidation yethusi eluhlaza.
Ngaba izixhobo zoluvo zifutshane?
Iisekethe ezimfutshane kwi-RPM, uxinzelelo, okanye i-throttle sensors inokukhupha umbane we-ECU we-5V, obangela i-alamu kunye nokuyeka.
Ukuba unikezelo lwamandla, iintambo, kunye nabenzi boluvo ziqhelekile kodwa i-ECU isangasebenzi kakuhle → I-ECU ngokwayo inokuba nesiphene.
II. Ezi mpawu ziphantse ziqinisekise ukusilela kwe-ECU
Ukubeka iliso kwesikrini esimnyama, akukho nxibelelwano, akukho mpendulo
Amandla aqhelekileyo kodwa umboniso ucime ngokupheleleyo okanye ubonisa "ECU Ayixhunyiwe".
Ulayishiwe kodwa injini yoyisakala ukuqalisa
Amandla aneleyo, amafutha, kunye noxinzelelo, kodwa i-starter crank ngaphandle kokuqala.
Iikhowudi zeempazamo eziqhubekayo ezingenakususwa
Ezinje Komatsu CA187, Caterpillar 1289, Kobelco P1/P2; Iikhowudi zivela ngokukhawuleza emva kokususwa.
Amandla oluvo lwe-5V afinyeziwe emhlabeni
Isiphaluka esifutshane sihlala nasemva kokuqhawula zonke izinzwa → i-chip yangaphakathi ye-ECU yamandla itshisiwe.
Imisebenzi engaqhelekanga, ukuzinza okuzenzekelayo, iintshukumo ezingaqhelekanga
Ukuzinzisa okungaqhelekanga, ukuphakamisa i-boom ngokuzenzekelayo, ukurhoxiswa kwebhakethi ngokuzenzekelayo; emva kokulawula imiba ye-hydraulic, i-ECU inephutha.
Umonakalo obonakalayo womzimba
Ukungenwa kwamanzi okucacileyo, ukutshisa, ukudumba, okanye ivumba elitshileyo → alinakulungiseka ngokubanzi, buyisela ngokuthe ngqo.
III. Isigwebo esiPhambili: Iyalungiseka vs. Kufuneka ithathelwe indawo
- Iyalungiseka (akukho Lutshintsho lufunekayo)
Kuphela iitshiphusi zamandla, iitransistor zomqhubi, okanye iitshiphu zonxibelelwano ezitshisiweyo
Umonakalo wamanzi kodwa i-CPU yonakele
Amandla phezulu kwaye anxibelelane ngokuqhelekileyo, kunye nokusilela komsebenzi kuphela
Iikhowudi zempazamo ezilungisiweyo kodwa ukufikelela kwenkqubo kuyafumaneka
Iindleko zokulungisa eziqhelekileyo: amakhulu amaninzi ukuya kwi-2,000 RMB - Kufuneka kubuyiselwe (ayilungiseki)
Burnt CPU / main chip (eyona "impazamo yesiphelo")
Ibhodi yesekethe etshisiweyo, imikhondo yobhedu eyaphukileyo, i-corrosion ebanzi
Umonakalo omkhulu wamanzi kunye nezinto ezixutywe ngokupheleleyo
I-ECU itshixiwe okanye i-VIN-botshelelwe ngaphandle kwesisombululo sokuvula
Imodeli ephelelwe lixesha ye-ECU iyekisiwe, akukho zitshiphu ezitshintshiweyo ezikhoyo
IV. Ukuhamba okuLula okuKhawulezayo koDiagnostic (Kubanini bomatshini)
Jonga ibhetri, iifizi, kunye nezihlanganisi
Nqamula zonke izixhobo zoluvo kwaye ubone ukuba iziphene ziyanyamalala
Ukuba iimpazamo ziyaqhubeka → I-ECU inesiphene
Vula i-ECU ukuze uhlole umonakalo wamanzi okanye iimpawu zokutsha
Lungisa uvavanyo lwevenkile:
Iyalungiseka → qhubeka nokulungisa
Ucaphulo olungenakulungiseka / lokulungiswa kufutshane nexabiso leyunithi entsha → buyisela ngokuthe ngqo
V. Kuza Kutshintshwa nini nge-ECU eNtsha Ngaphandle kokuthandabuza
I-excavator ngowona matshini wakho osebenzayo, onelahleko ephezulu yemihla ngemihla
I-ECU ayiphumelelanga ngokuphindaphindiweyo emva kokulungiswa okuninzi
Ulungiso lugqithise isiqingatha seendleko ze-ECU entsha
Imingcipheko ephezulu ngee-ECU ezisetyenzisiweyo, uloyiko lokuthenga iiyunithi ezitshixiweyo
