Nali iqoqo lezindlela zokuxilonga ezisebenzayo ezisetshenziswa yibo bobabili abanikazi bemishini kanye nochwepheshe bokukhanda, okuvumela ukuhlola okunzima—ngaphandle kwezinto zokusebenza ezichwepheshile—kokuthi iyunithi yokulawula i-elekthronikhi ye-excavator (ECU) iyalungiseka noma kufanele ishintshwe.
I. Umthetho Wokuqala Ukhipha Amaphutha Angewona awe-ECU
Izimpawu eziningi ezifana nokwehluleka kwe-ECU empeleni ziyizinkinga zangaphandle. Yenza lokhu kuhlola kuqala:
Ingabe i-voltage yebhethri ijwayelekile?
Uma amandla ogesi ehla ngaphansi kuka-21V ngesikhathi sokuqalisa, i-ECU ingase iqalise ama-alamu angamanga, yehluleke ukuqalisa, noma ivale injini.
Ingabe i-relay eyinhloko noma ama-fuse ayashaywa?
Ukunikezwa kwamandla kagesi okungazinzile ku-ECU udaba oluvame kakhulu.
Ingabe izixhumi zonakaliswe amanzi, zigqwalile, noma zixega?
Zikhiphe bese uhlola umswakama noma i-oxidation yethusi eluhlaza.
Ingabe izinzwa zine-circuited short?
Amasekhethi amafushane ku-RPM, izinzwa ze-pressure, noma i-throttle angawisa amandla kagesi we-ECU angu-5V, abangele ama-alamu kanye nokuma.
Uma ukunikezwa kwamandla, izintambo, nezinzwa kujwayelekile kodwa i-ECU isangasebenzi kahle → i-ECU ngokwayo cishe ayinasici.
II. Lezi zimpawu Zicishe Ziqinisekise Ukwehluleka Kwe-ECU
Gada isikrini esimnyama, akukho ukuxhumana, akukho mpendulo
Amandla ajwayelekile kodwa isibonisi sicishwe ngokuphelele noma sibonisa “I-ECU Ayixhunyiwe”.
Vula kodwa injini yehluleka ukuqala
Amandla anele, uphethiloli, nokuminyanisa, kodwa isiqalisi siyaqhuqha ngaphandle kokuqalisa.
Amakhodi ephutha aqhubekayo angakwazi ukusulwa
Ezifana Komatsu CA187, Caterpillar 1289, Kobelco P1/P2; amakhodi avela futhi ngokushesha ngemva kokususwa.
Amandla enzwa engu-5V afinyelelwe phansi
Umjikelezo omfushane uhlala ngisho nangemva kokunqamula zonke izinzwa → i-chip yangaphakathi ye-ECU yamandla ishile.
Imisebenzi engavamile, ukuzinza okuzenzakalelayo, ukunyakaza okungajwayelekile
Ukuma okungahleliwe, ukuphakamisa i-boom okuzenzakalelayo, ukuhlehliswa kwebhakede okuzenzakalelayo; ngemuva kokukhipha izinkinga ze-hydraulic, i-ECU inephutha.
Ukulimala ngokomzimba okubonakalayo
Ukungena kwamanzi okusobala, ukuvutha, izakhi eziqhumayo, noma iphunga elishisayo → ngokuvamile awalungiseki, buyisela ngokuqondile.
III. Isahlulelo Esibalulekile: Okulungisekayo vs. Kumele Kushintshwe
- Iyalungiseka (Akukho Ukumiselela Okudingekile)
Kushiswe kuphela ama-power chips, ama-transistor omshayeli, noma ama-chips okuxhumana
Ukulimala kwamanzi kodwa i-CPU iphelele
Inika amandla futhi ixhumane ngokujwayelekile, ngokwehluleka okuyingxenye kuphela kokusebenza
Amakhodi amaphutha alungisiwe kodwa ukufinyelela kwesistimu kuyatholakala
Izindleko zokulungisa ezijwayelekile: amakhulu ambalwa kuya ku-2,000 RMB - Kumele Kushintshwe (Akulungiseki)
I-CPU eshisiwe / i-chip eyinhloko ("iphutha lesiphetho" elivame kakhulu)
Ibhodi lesifunda elishisiwe, imikhondo yethusi ephukile, ukugqwala okukhulu
Ukulimala okukhulu kwamanzi anezingxenye ezigcwele oxidized
I-ECU ikhiyiwe noma iboshwe nge-VIN ngaphandle kwesixazululo sokuvula
Imodeli ephelelwe yisikhathi ye-ECU inqanyuliwe, awekho ama-chips atholakalayo
IV. Ukugeleza Okusheshayo Okulula Kakhulu (Kubanikazi Bomshini)
Hlola ibhethri, amafuse, nezixhumi
Nqamula zonke izinzwa futhi ubone ukuthi amaphutha ayanyamalala yini
Uma amaphutha eqhubeka → I-ECU inesici
Vula i-ECU ukuze uhlole umonakalo wamanzi noma izimpawu zokusha
Ukuhlolwa kwesitolo sokulungisa:
Iyalungiseka → qhubeka nokulungisa
Ikhwothi engalungiseki / ekhandwayo eduze nezindleko zeyunithi entsha → shintsha ngokuqondile
V. Nini Yokushintsha Nge-ECU Entsha Ngaphandle Kokungabaza
I-excavator ingumshini wakho oyinhloko osebenzayo, onokulahlekelwa okukhulu kwansuku zonke
I-ECU yehlulekile ngokuphindaphindiwe ngemva kokulungiswa okuningi
Isilinganiso sokulungisa sidlula ingxenye yezindleko ze-ECU entsha
Izingozi eziphezulu ngama-ECU asetshenzisiwe, ukwesaba ukuthenga amayunithi akhiyiwe
