Raws li cov remanufacturing nroj tsuag tau them nyiaj ntau thiab ntau xim, tib neeg kuj tau pib tshawb nrhiav ntau yam ntawm remanufacturing, thiab tau ua tiav tej yam kev tshawb fawb tshwm sim nyob rau hauv logistics, kev tswj, thiab technology ntawm remanufacturing.Hauv cov txheej txheem remanufacturing, nws yog ib qho tseem ceeb ntawm kev tu cov khoom kom ntseeg tau tias qhov zoo ntawm remanufacturing.Txoj kev tu thiab tu kom zoo yog qhov tseem ceeb rau qhov tseeb ntawm kev txheeb xyuas qhov chaw, ua kom muaj kev tsim kho kom zoo, txo cov nqi rov ua dua tshiab, thiab txhim kho lub neej ntawm cov khoom siv rov ua dua tshiab.tuaj yeem muaj qhov cuam tshuam tseem ceeb.
1. Txoj haujlwm thiab qhov tseem ceeb ntawm kev ntxuav hauv cov txheej txheem remanufacturing
Kev ntxuav ntawm qhov chaw ntawm cov khoom yog ib qho tseem ceeb hauv cov txheej txheem ntawm remanufacturing.Lub hauv paus ntawm kev faib kom paub qhov tseeb qhov tseeb, geometric duab raug, roughness, deg kev ua tau zoo, corrosion hnav thiab adhesion ntawm qhov chaw nto yog lub hauv paus rau kev faib khoom rau remanufacture qhov chaw..Qhov zoo ntawm ib feem ntawm qhov chaw tu ncaj qha cuam tshuam rau ib feem ntawm qhov chaw tsom, kev sim, remanufacturing ua, sib dhos zoo, thiab tom qab ntawd cuam tshuam rau qhov zoo ntawm cov khoom remanufactured.
Kev ntxuav yog siv cov kua ntxuav rau saum npoo ntawm qhov chaw ua haujlwm los ntawm kev siv cov cuab yeej tu, thiab siv cov cuab yeej siv tshuab, lub cev, tshuaj lossis electrochemical kom tshem tawm cov roj, corrosion, av nkos, nplai, carbon deposits thiab lwm yam av uas txuas rau saum npoo ntawm cov khoom. cov khoom siv thiab nws cov khoom, thiab ua rau nws Cov txheej txheem ntawm kev ua tiav qhov yuav tsum tau ua kom huv si ntawm qhov chaw ua haujlwm.Lub disassembled qhov chaw ntawm cov khoom pov tseg raug ntxuav raws li cov duab, cov khoom siv, pawg, kev puas tsuaj, thiab lwm yam, thiab cov txheej txheem sib raug yog siv los xyuas kom meej qhov zoo ntawm kev rov siv dua lossis rov ua dua ntawm cov khoom.Kev huv huv ntawm cov khoom yog ib qho tseem ceeb ntawm cov khoom lag luam remanufactured.Kev huv huv tsis zoo yuav tsis tsuas cuam tshuam rau cov txheej txheem remanufacturing ntawm cov khoom, tab sis kuj feem ntau ua rau kev ua tau zoo ntawm cov khoom lag luam poob qis, nquag hnav ntau dhau, txo qhov tseeb, thiab ua haujlwm luv luv.Cov khoom zoo.Kev huv huv zoo tuaj yeem txhim kho cov neeg siv khoom ntseeg siab hauv qhov zoo ntawm cov khoom siv rov ua dua tshiab.
Cov txheej txheem rov ua dua tshiab suav nrog kev rov ua dua tshiab ntawm cov khoom pov tseg, zoo li kev tu cov khoom ua ntej dismantling, dismantling, roughly testing of parts, cleaning of parts, precision detection of parts after cleaning, remanufacturing, assembly of remanufactured products, etc.Kev tu vaj tse muaj ob ntu: kev tu tag nrho ntawm cov khoom pov tseg thiab kev ntxuav ntawm qhov chaw.Lub qub yog tsuas yog tshem tawm cov plua plav thiab lwm yam av ntawm qhov pom ntawm cov khoom, thiab tom kawg yog tsuas yog tshem tawm cov roj, nplai, xeb, carbon deposits thiab lwm yam av ntawm qhov chaw.Cov roj thiab roj txheej ntawm qhov chaw, thiab lwm yam, xyuas qhov hnav ntawm qhov chaw, qhov chaw microcracks lossis lwm yam tsis ua haujlwm los txiav txim siab seb cov khoom puas tuaj yeem siv lossis yuav tsum tau rov ua dua tshiab.Lub remanufacturing tu yog txawv los ntawm kev tu cov txheej txheem txij nkawm.Lub ntsiab tu engineer ntxuav lub faulty qhov chaw thiab lwm yam khoom ua ntej txij nkawm, thaum remanufacturing yuav tsum tau tag nrho cov khoom pov tseg qhov chaw yuav tsum tau ntxuav tag nrho, thiaj li hais tias qhov zoo ntawm remanufactured qhov chaw tuaj yeem ncav cuag qib ntawm cov khoom tshiab.txheem.Yog li ntawd, kev ua haujlwm tu lub luag haujlwm tseem ceeb hauv cov txheej txheem remanufacturing, thiab kev ua haujlwm hnyav ncaj qha cuam tshuam rau tus nqi ntawm cov khoom siv rov ua dua tshiab, yog li nws yuav tsum tau ua tib zoo saib xyuas.
2. Kev siv tshuab ntxuav thiab nws txoj kev txhim kho hauv kev tsim kho dua tshiab
2.1 Cleaning technology rau remanufacturing
Zoo li cov txheej txheem dismantling, nws yog tsis yooj yim sua rau kev tu cov txheej txheem ncaj qha los ntawm cov txheej txheem tsim, uas yuav tsum tau muaj kev tshawb fawb ntawm cov txheej txheem tshiab thiab kev tsim kho tshiab remanufacturing tu cov cuab yeej hauv manufacturers thiab remanufacturing khoom lwm tus neeg.Raws li qhov chaw tu, lub hom phiaj, qhov nyuaj ntawm cov ntaub ntawv, thiab lwm yam, cov txheej txheem tu siv hauv cov txheej txheem ntxuav.Cov txheej txheem ntxuav feem ntau yog siv cov roj av tu, dej kub tshuaj ntxuav lossis chav ntxuav, tshuaj ntxuav cov tshuaj ntxuav cov tshuaj ntxuav dej, txhuam los yog hlau txhuam txhuam, kev kub siab lossis ib txwm siv tshuaj ntxuav, sandblasting, electrolytic tu, roj theem tu, ultrasonic tu. thiab Multi-kauj ruam tu thiab lwm txoj kev.
Txhawm rau ua kom tiav txhua txoj kev tu, tag nrho cov txheej txheem ntawm ntau yam tshwj xeeb tu cov cuab yeej siv tau, suav nrog: tshuaj ntxuav lub tshuab, tshuaj tsuag rab phom tshuab, tshuab ntxhua khaub ncaws, tshuab ntxuav tshwj xeeb, thiab lwm yam. Kev xaiv cov cuab yeej yuav tsum tau txiav txim siab raws li cov qauv remanufacturing, yuav tsum tau, ib puag ncig tiv thaiv, nqi thiab remanufacturing site.
2.2 Txoj kev loj hlob ntawm kev tu tshuab
Cov kauj ruam tu yog qhov tseem ceeb ntawm kev kis kab mob thaum rov ua dua tshiab.Ntxiv mus, cov khoom tsis zoo uas tsim los ntawm cov txheej txheem ntxuav feem ntau ua rau muaj kev phom sij rau ib puag ncig.Ntxiv mus, tus nqi ntawm kev pov tseg tsis zoo ntawm cov khoom tsis zoo kuj tseem ceeb heev.Yog li ntawd, nyob rau hauv lub remanufacturing tu cov kauj ruam, nws yog ib qhov tsim nyog los txo qhov kev puas tsuaj ntawm cov tshuaj ntxuav tu rau ib puag ncig thiab txais yuav ntsuab tu tshuab.Remanufacturers tau ua ntau txoj kev tshawb fawb thiab kev siv ntau dua ntawm cov thev naus laus zis tshiab thiab siv tau zoo dua, thiab cov txheej txheem ntxuav tau dhau los ua ib puag ncig zoo.Thaum txhim kho kev tu kom zoo, txo qhov tso tawm ntawm cov khoom tsis zoo, txo cov kev cuam tshuam ntawm ecological ib puag ncig, nce kev tiv thaiv ib puag ncig ntawm cov txheej txheem ntxuav, thiab ua kom cov khoom zoo.
3 .Kev ua kom huv huv ntawm txhua theem ntawm kev rov ua dua tshiab
Kev tu hauv cov txheej txheem remanufacturing feem ntau suav nrog kev tu sab nraud ntawm cov khoom pov tseg ua ntej dismantling thiab tu cov khoom tom qab dismantling.
3.1 Ntxuav ua ntej disassembly
Kev ntxuav ua ntej dismantling feem ntau yog hais txog kev ntxuav sab nraud ntawm cov khoom siv pov tseg ua ntej dismantling.Nws lub hom phiaj tseem ceeb yog tshem tawm cov hmoov av ntau, roj, sediment thiab lwm yam av uas nyob rau sab nraud ntawm cov khoom pov tseg, thiaj li ua kom yooj yim dismantling thiab tsis txhob muaj plua plav thiab roj.Tos kom cov khoom raug nyiag mus rau hauv lub Hoobkas txheej txheem.Kev tu sab nraud feem ntau yog siv cov kais dej los yog cov dej ntws tawm siab.Rau high-ntom thiab tuab-txheej av av, ntxiv tus nqi uas tsim nyog tu tshuaj rau dej thiab nce cov dej txau thiab dej kom sov.
Feem ntau siv cov cuab yeej tu sab nraud feem ntau suav nrog ib rab phom dav hlau tu tshuab thiab ntau lub tshuab dav hlau tu tshuab.Cov qub tsuas yog tso siab rau kev ua haujlwm ntawm lub dav hlau tiv thaiv siab lossis lub dav hlau dej qab zib lossis cov tshuaj ua haujlwm ntawm lub dav hlau thiab cov tshuaj ntxuav kom tshem tawm cov av.Lub tom kawg muaj ob hom, lub qhov rooj ncej movable hom thiab qhov tunnel tsau hom.Qhov chaw teeb tsa thiab qhov ntau ntawm cov nozzles sib txawv raws li lub hom phiaj ntawm cov khoom siv.
