Chikalatachi ndi chongofuna kudziwa basi ndipo sichikulunjika mtundu kapena chinthu chilichonse.
Kuti muwunikire magwiridwe antchito a magawo osiyanasiyana owongolera zofukula (monga ECU, EECU, ndi IECU), kutsimikizira kumatha kuchitika kudzera muzochitika zingapo, kuphatikiza magwiridwe antchito enieni, malingaliro olakwika, komanso kusinthika kwa chilengedwe. Kuphatikizidwa ndi zochitika zenizeni zama brand ngati Komatsu, Caterpillar, SANY, ndi Volvo, magawo otsatirawa amafotokoza mwatsatanetsatane momwe mungasiyanitsire magawo apamwamba kwambiri komanso otsika kwambiri potengera momwe amagwirira ntchito, kuzindikira zolakwika, komanso kusinthika kwa chilengedwe, ndikugwiritsa ntchito mwamphamvu:
Caterpillar 320D: Kusiyanitsa Kwantchito Pakati pa Mabodi Ozungulira Apamwamba ndi Otsika (Magawo Owongolera)
Mlandu 1: Gulu Loyang'anira Ubwino Wapamwamba
Mu ntchito yayikulu yapadziko lapansi, chofufutira cha Caterpillar 320D chokhala ndi bolodi yadera lopangira zida zoyambira (OEM) chimatha kusintha moyenera momwe zinthu zimagwirira ntchito. Pogwira ntchito m'nthaka yofewa, gawo lowongolera lidazindikira kukana kukumba pang'ono kudzera pa masensa ndikusinthira kunjira yachuma yotsika mphamvu, kuchepetsa kugwiritsa ntchito mafuta ndi 15% poyerekeza ndi zida zina zagulu lomwelo. Pantchito zolemetsa za migodi ndi zothyola miyala, idachulukitsa mwachangu mphamvu ya injini, ndikuwonetsetsa kuti ntchito yokhazikika ya 200-300 cubic metres pa ola - 10% -20% yogwira bwino ntchito kuposa zida zofananira zamtundu womwewo.
Kuphatikiza apo, mkati mwa ntchito yomanga ngalande zapansi panthaka, owongolera adawona kukwera kwachilendo kwa kutentha kwamafuta a hydraulic ndipo nthawi yomweyo adayambitsa alamu pachiwonetsero. Ogwira ntchito yosamalira anayeretsa mwachangu zinyalala za rediyeta potengera chenjezoli, kuletsa kuwonongeka kwa ma hydraulic system ndikuwonetsa kulakwitsa kwakukulu kochenjeza koyambirira.
Mlandu 2: Chigawo Choyang'anira Makhalidwe Otsika
Gulu lina la Caterpillar 320D linali ndi bolodi yake yowonongeka ya OEM yomwe idasinthidwa ndi njira yotsika mtengo kuchokera kugwero losaloledwa. Kuyambira pagawo loyambira logwiritsa ntchito, wofukulayo nthawi zambiri amakumana ndi injini idging popanda kuyankha pakukumba, ndipo palibe nyali zochenjeza zomwe zidayatsidwa pagawo la zida. Kuyang'anira kosamalira kunawonetsa kuti kusungunula kotayirira pamapini amkati a gawo lowongolera lotsika kumalepheretsa ma hydraulic system kuti asalandire malamulo.
Vutoli linachedwetsa ntchitoyo kwa maola angapo. Pambuyo pake, chifukwa cha kulephera kwa gawo lowongolera mphamvu moyenera, kugwiritsa ntchito mafuta kunakwera ndi 30%, ndipo ntchito zokumba zidakhala zovuta. Chigawocho chinathetsedwa kwathunthu pambuyo pa miyezi itatu yogwiritsidwa ntchito chifukwa cha kutenthedwa kwa dera.
SANY SY19E: Kutsimikizira Ubwino Wabwino wa Magawo Ophatikizana Owongolera
Chigawo choyang'anira chophatikizika chonse chokhala ndi chofufutira chamagetsi cha SANY SY19E ndi chitsanzo cha mawonekedwe apamwamba kwambiri. Chigawochi chimagwirizanitsa ntchito zingapo, kuphatikizapo galimoto yamagetsi ya MCU, OBC yojambulira, ndi magetsi otsika kwambiri a DCDC. Poyerekeza ndi mayunitsi owongolera omwe amagawidwa kale, ali ndi kukula kochepa komanso kugwirizanitsa mwamphamvu.
Mu pulojekiti yokonzanso m'nyumba pafakitale yazakudya, gawo lowongolera linagwira ntchito limodzi ndi SLSS hydraulic system kuti lilamulire ndendende kuyenda kutengera kusintha kwa katundu. Idawonetsa kuwongolera kwapang'onopang'ono kwa chidebecho, ndikupangitsa kukumba kolondola m'malo opapatiza. Panthawiyi, zophatikizidwa ndi wolamulira wanzeru wowongolera kutentha, zidazo zimasunga kutentha kosasunthika pakugwira ntchito kwa maola ambiri, popanda ma alarm omwe amanenedwa ngakhale pambuyo pa maola 8 otsatizana a ntchito.
Mosiyana ndi izi, zida zopikisana zamatani omwewo okhala ndi mayunitsi owongolera nthawi zambiri zimachedwa kuchitapo kanthu. Komanso, chifukwa cha kutentha kwapang'onopang'ono kwa magawo awo owongolera, ochita nawo mpikisanowo mobwerezabwereza adayambitsa chitetezo chotseka chifukwa cha kutentha kwambiri. Kufananitsa uku kukuwonetsa ubwino wamtundu wa SANY wogwirizanitsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
Volvo Excavators: Kuyerekeza kwa Control Units' Environmental Adaptability
Mu pulojekiti yofukula ya Volvo padoko, magawo awiri adayikidwa ndi gawo lowongolera la OEM ndi gawo lachitatu lowongolera zabodza, motsatana, kuti asamalire ntchito m'malo onyamula katundu. Malo a doko amadziŵika ndi chinyezi chachikulu komanso dzimbiri lopopera mchere pafupipafupi.
Chigawo chowongolera cha OEM chinali ndi IP67 chitetezo chokhala ndi mapangidwe omata, nyumba yotetezedwa ndi dzimbiri, komanso zokutira zoteteza chinyezi pamabwalo amkati. Pazaka 2 zogwiritsidwa ntchito, zidangokumana ndi kusinthasintha kwakung'ono kwa siginecha, komwe kudapezeka kuti sikulumikizana bwino ndi mawaya-osagwirizana ndi gawo lowongolera palokha.
Mosiyana ndi izi, chofukula chokhala ndi zida zowongolera zachinyengo chinayamba kukumana ndi zolakwika zolumikizana pafupipafupi pambuyo pa miyezi 6 yogwiritsidwa ntchito, ndi ma alarm osalekeza pagulu la zida. Kuyang'ana kwapang'onopang'ono kunawonetsa kuti nyumba zachinyengo zidali ndi zosindikizira bwino; Kulowetsedwa kwa utsi wa mchere kunayambitsa dzimbiri kwa matabwa amkati komanso kusweka kwa pini. Kuphatikiza apo, gawo lowongolera zachinyengo silinathe kusinthira kumayendedwe apamwamba adoko. Pakugwedezeka komwe kumachitika chifukwa chonyamula katundu wolemetsa, kutumiza kwa data kunasokonezedwa kangapo, zomwe zimapangitsa kuti pakhale zolakwika za hydraulic system. Pambuyo pake, gawo lachinyengo lidasinthidwa ndi OEM chifukwa chakuwonongeka kosasinthika.
Chofukula cha Doosan chinazimitsa mwadzidzidzi panthawi yogwira ntchito, ndi chida chosonyeza "ECU communication error" ndi "voltage yachilendo ya jenereta." The excavator analephera kuyambitsanso pambuyo pake. Ogwira ntchito zosamalira anatsatira njira zokhazikika zothetsera mavuto:
Zatsimikizira kuti mphamvu ya batri ndi ma fuse anali abwinobwino.
Zofukula za Doosan: Kuzindikiritsa Ubwino wa Unit Unit Kupyolera mu Kuzindikira Kolakwa
Anayang'ana chodutsa cha ECU ndikupeza kuti voteji yochokera kumalo otsekera mwadzidzidzi kupita ku ECU inali 0V (voltage yokhazikika iyenera kukhala 25V).
Pamapeto pake adazindikira mawaya otha kukhala chifukwa cha kutha kwa magetsi a ECU.
Panthawiyi, ubwino wa chipangizo chapamwamba kwambiri chowongolera chinawonekera: pambuyo poti kulephera kwa magetsi kunathetsedwa ndipo ma waya adalumikizidwanso, OEM ECU inayambiranso kugwira ntchito yachibadwa popanda kusokonezeka kwa deta kapena kuwonongeka kwa ntchito. Magawo onse adakhalabe okhazikika pazotsatira.
M'mbuyomu, wofukula wina wa Doosan wokhala ndi ECU yotsika kwambiri adakumana ndi vuto lofananira lawaya. Cholakwikacho chitatha, ECU yotsika mtengo imakhalabe ndi vuto la jekeseni wamafuta. Pambuyo pake zidatsimikiziridwa kuti mabwalo amkati amtundu wocheperako anali ndi mphamvu zochepa zotsutsana ndi kugwedezeka, zomwe zidapangitsa kuwonongeka kosasinthika panthawi yayifupi. Mlanduwu ukuwonetsa kuti magawo owongolera otsika amakhala otsika kwambiri poyerekeza ndi apamwamba kwambiri polimbana ndi zolakwika.
Case New Holland Smart Power System-Matched Control Unit: Mapangidwe Ophatikizidwa Akuwonetsa Kuchita Kwapamwamba
Chidutswa cha zida zomangira chinali ndi makina anzeru a Case New Holland CSP, omwe gawo lake lofananira limaphatikizidwa ndi pampu yamagetsi yamagetsi yamagetsi. Chigawo chowongolerachi chimathandizira ntchito monga anti-stall electronic and adaptive torque control. Pamachitidwe ovuta, imathandizira kufananiza bwino pakati pa kuyamwa kwamphamvu kwa pampu ya hydraulic ndi mphamvu yomwe ilipo ya injini.
Mwachitsanzo, panthawi ya kukumba kwakukulu, gawo lolamulira likhoza kusintha magawo a hydraulic system mu nthawi yeniyeni, kulola kuti zipangizo zizigwira ntchito mokhazikika pansi pa dongosolo la 315 bar popanda kusokoneza mphamvu kapena zovuta zachilendo. Poyerekeza ndi zida zokhazikika zokhala ndi mpope wosiyana ndi kapangidwe ka ECU, gawo lophatikizika lowongolerali silimangofewetsa masanjidwewo komanso limachepetsa kuchedwa kwa ma siginecha, kuwongolera magwiridwe antchito ndi 20%.
Mosiyana ndi izi, ofukula amtundu womwewo wokhala ndi zida zowongolera wamba nthawi zambiri amakumana ndi kutsika kwa liwiro la injini komanso zochita za hydraulic zamphamvu pansi pazovuta kwambiri. Komanso, kugwiritsa ntchito mafuta awo kunali 18% kuposa zida zomwe zili ndi gawo lowongolera la Case New Holland. Izi zikuwonetsa zabwino zazikulu zamagawo owongolera apamwamba kwambiri mu synergy system komanso kuwongolera bwino
