Cov ntaub ntawv no tsuas yog siv rau kev siv xwb thiab tsis tsom rau ib qho tshwj xeeb hom lossis cov khoom lag luam.
Txhawm rau ntsuas qhov ua tau zoo ntawm ntau lub tshuab excavator tswj (xws li ECU, EECU, thiab IECU), kev txheeb xyuas tuaj yeem ua los ntawm ntau qhov xwm txheej, suav nrog kev ua haujlwm tiag tiag, kev tawm tsam yuam kev, thiab kev hloov pauv ib puag ncig. Ua ke nrog cov xwm txheej tiag tiag ntawm cov khoom lag luam tseem ceeb xws li Komatsu, Kab ntsig, SANY, thiab Volvo, cov ntu hauv qab no piav qhia yuav ua li cas kom paub qhov txawv ntawm cov khoom siv zoo thiab cov tswj tsis zoo los ntawm kev xav ntawm kev ua tau zoo, kev kuaj mob, thiab kev hloov pauv ib puag ncig, nrog rau kev siv tau zoo:
Kab ntsig 320D: Kev ua haujlwm sib txawv ntawm Cov Khoom Siv Hluav Taws Xob thiab Cov Hluav Taws Xob Hluav Taws Xob (Control Units)
Case 1: High-Quality Control Unit
Hauv kev ua haujlwm loj hauv ntiaj teb, Kab ntsig 320D excavator nruab nrog cov khoom tsim khoom qub (OEM) Circuit Court board tuaj yeem hloov kho kom haum rau cov haujlwm sib txawv. Thaum kev khiav hauj lwm hauv cov av mos, chav tswj xyuas tau pom qhov kev khawb qis ntawm cov sensors thiab tau hloov mus rau hom kev lag luam uas tsis muaj zog, txo cov roj noj los ntawm 15% piv rau lwm cov khoom siv ntawm tib chav kawm. Rau kev ua haujlwm hnyav thiab pob zeb tawg, nws nrawm nrawm rau lub cav tso zis torque, ua kom lub zog ua haujlwm ruaj khov ntawm 200-300 cubic meters ib teev - 10% -20% ntau dua li cov khoom siv ntawm tib hom.
Tsis tas li ntawd, thaum lub sij hawm tsim kho qhov av subway, lub chaw tswj xyuas tau pom qhov txawv txav ntawm cov roj hydraulic thiab tam sim ntawd ua rau lub tswb ntawm cov zaub. Cov neeg ua haujlwm tu cov neeg ua haujlwm tam sim ntawd ntxuav cov khib nyiab ntawm lub tshuab hluav taws xob raws li qhov kev ceeb toom no, tiv thaiv kev ua haujlwm hydraulic thiab ua rau muaj kev ua txhaum loj thaum ceeb toom muaj peev xwm.
Case 2: Tsawg-Quality Control Unit
Lwm Caterpillar 320D tau nws lub rooj tsav xwm OEM puas tau hloov nrog tus nqi qis los ntawm qhov chaw tsis tau tso cai. Los ntawm qhov pib siv theem, lub excavator feem ntau ntsib lub cav idling uas tsis muaj lus teb los ntawm kev khawb, thiab tsis muaj teeb ceeb toom rau ntawm lub ntsuas vaj huam sib luag. Kev saib xyuas kev saib xyuas tau qhia tias xoob soldering ntawm cov pins sab hauv ntawm chav tswj tsis zoo tiv thaiv lub tshuab hydraulic los ntawm kev txais cov lus txib.
Qhov kev txhaum no ncua qhov project rau ob peb teev. Tom qab ntawd, vim lub zog tswj tsis muaj peev xwm tswj hwm lub zog kom raug, kev siv roj tau nce siab los ntawm 30%, thiab kev khawb ua haujlwm tau dhau los ua jerky. Chav tsev tau muab pov tseg tag nrho tom qab 3 lub hlis ntawm kev siv vim yog hluav taws xob hluav taws xob.
SANY SY19E: Kev txheeb xyuas qhov zoo ntawm Kev Tswj Xyuas Kev Sib Koom
Tag nrho-hauv-ib qho kev tswj hwm kev sib koom ua ke nruab rau hauv SANY SY19E mini hluav taws xob excavator yog ib qho piv txwv ntawm chav tswj zoo. Chav tsev no koom ua ke ntau yam haujlwm, suav nrog lub tshuab hluav taws xob MCU, them OBC, thiab lub zog hluav taws xob qis DCDC. Muab piv rau cov kev tswj hwm kev faib tawm ib txwm muaj, nws muaj qhov me me thiab muaj zog sib xws.
Nyob rau hauv ib qho kev kho tshiab sab hauv tsev ntawm lub chaw tsim khoom noj khoom haus, chav tswj tau ua haujlwm sib koom ua ke nrog SLSS hydraulic system kom tswj tau qhov ntws raws li kev hloov pauv. Nws nthuav tawm zoo heev micro-tswj ntawm lub thoob, ua kom muaj tseeb kaum khawb hauv qhov chaw nqaim. Lub caij no, ua ke nrog lub tshuab hluav taws xob tswj hluav taws xob ntse, cov cuab yeej tswj xyuas qhov kub thiab txias thaum lub sijhawm ua haujlwm ntev, tsis muaj kev ceeb toom txhaum cai txawm tias tom qab 8 teev ua haujlwm sib law liag.
Hauv qhov sib piv, cov cuab yeej sib tw ntawm tib lub tonnage nruab nrog cov qauv tswj hwm feem ntau ntsib kev ua haujlwm qeeb. Ntxiv mus, vim tsis zoo cua sov dissipation ntawm lawv cov tswj units, cov neeg sib tw no rov ua rau kev tiv thaiv kaw vim overheating. Qhov kev sib piv no qhia txog qhov zoo ntawm SANY cov kev tswj hwm kev sib koom ua ke ntawm kev ua haujlwm ruaj khov thiab qib kev sib koom ua ke.
Volvo Excavators: Sib piv ntawm Cov Chaw Tswj Xyuas 'Environmental Adaptability
Hauv qhov project Volvo excavator ntawm qhov chaw nres nkoj, ob chav nyob tau nruab nrog lub chaw tswj hwm OEM thiab chav tswj hwm thib peb, raws li, rau qib kev ua haujlwm hauv cov khoom thauj khoom. Qhov chaw nres nkoj ib puag ncig yog tus cwj pwm los ntawm cov av noo siab thiab nquag ntsev tsuag corrosion.
Lub tsev tswj hwm OEM muaj qhov tshwj xeeb IP67 tiv thaiv kev ntsuas nrog cov qauv tsim, kev tiv thaiv corrosion-kho vaj tse, thiab cov txheej txheem dej tsis zoo ntawm cov kab hluav taws xob sab hauv. Tshaj li 2 xyoos ntawm kev siv, nws tsuas yog ntsib ib qho kev hloov pauv me me, uas tau kuaj pom tias tsis zoo ntawm cov hlua khi hlua sib cuag - tsis cuam tshuam rau chav tswj nws tus kheej.
Nyob rau hauv sib piv, lub excavator nrog lub counterfeit control unit pib muaj kev sib txuas lus faults tom qab 6 lub hlis ntawm kev siv, nrog tas mus li tswb ntawm lub ntsuas vaj huam sib luag. Kev tshuaj xyuas disassembly qhia tau tias cov khoom cuav ntawm lub tsev muaj kev sib khi tsis zoo; ntsev tsuag intrusion ua rau corrosion ntawm sab hauv Circuit Court boards thiab oxidation-induced tus pin breakage. Tsis tas li ntawd, chav tswj kev ua txhaum cai tsis tuaj yeem hloov mus rau qhov chaw nres nkoj qhov kev vibration siab. Thaum lub sij hawm vibrations tshwm sim los ntawm kev thauj khoom hnyav, cov ntaub ntawv xa tawm tau cuam tshuam ntau zaus, ua rau cov kev ua tsis raug ntawm hydraulic system. Thaum kawg, chav tsev cuav raug hloov nrog OEM ib qho vim qhov kev puas tsuaj uas tsis tuaj yeem kho.
Lub Doosan excavator dheev kaw thaum lub sijhawm ua haujlwm, nrog lub ntsuas vaj huam sib luag qhia "ECU kev sib txuas lus yuam kev" thiab "qhov hluav taws xob txawv txav." Lub excavator ua tsis tiav rov pib dua tom qab. Cov neeg saib xyuas tau ua raws li cov txheej txheem daws teeb meem:
Paub meej tias lub roj teeb voltage thiab fuses yog qhov qub.
Doosan Excavators: Txheeb xyuas Lub Tsev Tswj Xyuas Zoo Los ntawm Kev Tshawb Fawb Kev Ua Phem
Tshawb xyuas ECU lub davhlau ya nyob twg thiab pom tias qhov hluav taws xob los ntawm qhov hluav taws xob kaw thaum muaj xwm txheej ceev rau ECU yog 0V (tus qauv voltage yuav tsum yog 25V).
Thaum kawg tau txheeb xyuas cov hlua khi hlua khi uas ua rau ECU tsis ua haujlwm.
Nyob rau ntawm lub sijhawm no, qhov zoo ntawm chav tswj kev tswj tau zoo tau tshwm sim: tom qab lub zog tsis ua haujlwm raug daws thiab cov hlua hlau tau txuas dua, OEM ECU tau rov ua haujlwm tam sim ntawd yam tsis muaj cov ntaub ntawv tsis meej pem lossis kev ua haujlwm tsis zoo. Txhua qhov kev ntsuas tseem nyob ruaj khov hauv kev ua haujlwm tom ntej.
Yav dhau los, lwm Doosan excavator nrog lub ECU tsis zoo tau ntsib ib qho zoo sib xws ntawm cov hlua khi luv luv. Tom qab qhov kev ua txhaum raug kho, qhov tsis zoo ECU tseem niaj hnub ntsib teeb meem roj txhaj tshuaj. Nws thiaj li tau lees paub tias qhov tsis zoo ntawm cov khoom siv hluav taws xob sab hauv muaj qhov tsis zoo los tiv thaiv kev poob siab, ua rau tsis muaj kev puas tsuaj thaum lub sijhawm luv luv. Cov ntaub ntawv no qhia tau hais tias cov kev tswj xyuas tsis zoo yog qhov qis dua rau cov khoom zoo nyob rau hauv cov nqe lus ntawm kev ua txhaum.
Case New Holland Smart Power System-Matched Control Unit: Integrated Design Demonstrates High-Quality Performance
Ib daim ntawm cov cuab yeej tsim kho tau nruab nrog Case New Holland CSP ntse lub zog, uas nws qhov chaw tswj tau sib koom ua ke nrog lub tshuab hluav taws xob digital tswj. Chav tswj no txhawb nqa kev ua haujlwm xws li hluav taws xob tiv thaiv lub rooj muag khoom thiab kev tswj lub zog hloov pauv. Thaum lub sijhawm ua haujlwm nyuaj, nws ua rau muaj qhov sib txuam ntawm lub twj tso kua mis hydraulic lub zog nqus thiab lub cav muaj zog.
Piv txwv li, thaum lub sijhawm ua haujlwm hnyav, chav tswj tau tuaj yeem kho qhov ntsuas hydraulic hauv lub sijhawm, tso cai rau cov cuab yeej ua haujlwm ruaj khov nyob rau hauv lub zog siab ntawm 315 bar yam tsis muaj kev cuam tshuam fais fab lossis teeb meem tsis zoo. Piv nrog rau cov khoom siv txheem nrog lub twj tso kua mis sib cais thiab ECU tsim, chav tswj kev sib koom ua ke tsis yog tsuas yog ua kom yooj yim layout tab sis kuj txo cov teeb liab xa mus qeeb, txhim kho kev ua haujlwm ntawm 20%.
Nyob rau hauv sib piv, excavators ntawm tib hom nruab nrog txheem tswj units nquag ntsib cav ceev tee thiab jerky hydraulic ua nyob rau hauv high-pressure tej yam kev mob. Ntxiv mus, lawv cov roj noj yog 18% siab dua li cov khoom siv nrog Case New Holland tswj chav tsev. Qhov no qhia txog cov txiaj ntsig tseem ceeb ntawm kev tswj hwm zoo hauv kev sib koom ua ke thiab kev tswj xyuas meej
