Pano pali njira zodziwira zomwe zimagwiritsidwa ntchito ndi eni ake onse ndi akatswiri okonza makina, kulola kuwunika movutikira-popanda zida zaukadaulo - ngati makina owongolera amagetsi a Excavator (ECU) amatha kukonza kapena ayenera kusinthidwa.
I. Lamulo Loyamba Loletsa Zolakwa Zosakhala za ECU
Zizindikiro zambiri zokhala ngati kulephera kwa ECU ndizovuta zakunja. Chitani macheke awa kaye:
Kodi mphamvu ya batire ndi yabwinobwino?
Ngati magetsi atsika pansi pa 21V poyambitsa, ECU ikhoza kuyambitsa ma alarm abodza, kulephera kuyambitsa, kapena kutseka injini.
Kodi relay yayikulu kapena ma fuse amawomberedwa?
Kusakhazikika kwa magetsi ku ECU ndi nkhani yofala kwambiri.
Kodi zolumikizira zawonongeka ndi madzi, zachita dzimbiri, kapena zasokonekera?
Chotsani iwo ndikuyang'ana chinyezi kapena oxidation ya mkuwa wobiriwira.
Kodi masensa amafupikitsidwa?
Mabwalo afupiafupi mu RPM, kupanikizika, kapena masensa a throttle amatha kugwetsa magetsi a ECU a 5V, kuchititsa ma alarm ndi kuyimitsa.
Ngati magetsi, ma waya, ndi masensa ndi abwinobwino koma ECU ikadali yosagwira ntchito → ECU yokhayo ndiyotheka.
II. Zizindikiro Izi Pafupifupi Zikutsimikizira Kulephera kwa ECU
Yang'anirani chophimba chakuda, palibe kulumikizana, palibe kuyankha
Mphamvu ndizabwinobwino koma chiwonetserocho chimazimitsidwa kapena kuwonetsa "ECU Osalumikizidwa".
Yayatsa koma injini ikulephera kuyambitsa
Mphamvu yokwanira, mafuta, ndi kuponderezana, koma choyambira chimayamba popanda kuyambitsa.
Manambala olakwika osalekeza omwe sangathe kuchotsedwa
Monga Komatsu CA187, Caterpillar 1289, Kobelco P1/P2; Zizindikiro zimawonekeranso pambuyo pochotsa.
Mphamvu ya sensa ya 5V idafupikitsidwa mpaka pansi
Dera lalifupi limakhalabe ngakhale mutadula masensa onse → chip chamkati cha ECU chatenthedwa.
Ntchito zosazolowereka, kuyimitsidwa kodziwikiratu, mayendedwe osinthika
Kuyimitsidwa mwachisawawa, kukweza kwachangu, kubweza chidebe chodziwikiratu; Pambuyo pothetsa mavuto a hydraulic, ECU ili ndi vuto.
Kuwonongeka kwakuthupi kowoneka
Kulowa kwamadzi kodziwikiratu, kuyaka, kuphulika, kapena fungo loyaka moto → nthawi zambiri sizingakonzedwe, sinthani mwachindunji.
III. Chigamulo Chachikulu: Zokonzanso vs. Must Replace
- Zokonzedwanso (Palibe Cholowa Chofunika)
Ma tchipisi amagetsi okha, ma transistors oyendetsa, kapena ma tchipisi olumikizirana ndi omwe amawotchedwa
Kuwonongeka kwa madzi koma CPU siili bwino
Imakulitsa ndikulumikizana bwino, ndikulephera kugwira ntchito pang'ono
Manambala olakwika okhazikika koma mwayi wopezeka pamakina ukupezeka
Mtengo wokonzekera: mazana angapo mpaka 2,000 RMB - Iyenera Kusintha (Zosakonzekera)
Burnt CPU / main chip (zofala kwambiri "zolakwika zomaliza")
Kuwotchedwa-kupyolera mu bolodi lozungulira, mikwingwirima yamkuwa yosweka, dzimbiri lalikulu
Kuwonongeka kwakukulu kwamadzi ndi zigawo zodzaza ndi okosijeni
ECU yotsekedwa kapena VIN yomangidwa popanda njira yotsegula
ECU yachikale ya mtundu wasiya, palibe tchipisi tolowa m'malo
IV. Kuyenda Kwambiri Mwachangu Kwambiri (Kwa Eni Makina)
Onani mabatire, ma fuse, ndi zolumikizira
Lumikizani masensa onse ndikuwona ngati zolakwika zikutha
Ngati zolakwika zikupitilira → ECU ilibe vuto
Tsegulani ECU kuti muwone kuwonongeka kwa madzi kapena zizindikiro zowotcha
Kukonza sitolo:
Zokonzanso → pitilizani kukonza
Zosasinthika / zokonzedwa pafupi ndi mtengo wa chipangizo chatsopano → sinthani mwachindunji
V. Momwe Mungasinthire ndi ECU Yatsopano Mosakayikira
Chofukula ndiye makina anu oyambira ogwirira ntchito, omwe amatayika kwambiri tsiku lililonse
ECU yalephera mobwerezabwereza pambuyo pokonzanso kangapo
Kukonzanso kupitilira theka la mtengo wa ECU yatsopano
Zowopsa zazikulu ndi ma ECU ogwiritsidwa ntchito, kuopa kugula mayunitsi okhoma
