Automotive alternator - lub ntsiab tivthaiv ntawm lub internal combustion engine hluav taws xob system.
Automobile alternator, lub tshuab hluav taws xob yog lub zog tseem ceeb ntawm lub tsheb, uas tau tsav los ntawm lub cav, nws yog nyob rau hauv ib txwm ua haujlwm, ntxiv rau lub oob khab tag nrho cov khoom siv hluav taws xob, yog tias muaj lub zog ntau dhau, thiab tom qab ntawd them lub roj teeb.
Kuv yuav paub li cas yog lub tshuab hluav taws xob faulty
Thaum lub tshuab hluav taws xob xav tias tsis ua haujlwm, nws tuaj yeem raug sim ua ntej ntawm lub tsheb, thiab lub cev muaj zog tuaj yeem raug tshem tawm rau kev sim ntxiv. Cov cuab yeej siv hauv kev tshawb nrhiav tuaj yeem yog multimeters (voltage, tsis kam), dav DC voltmeter, DC ammeter thiab oscilloscope, thiab lwm yam., kuj tuaj yeem siv los ua cov teeb ntsuas me me nrog lub tsheb teeb, teeb nyem, thiab lwm yam, thiab tuaj yeem kuaj pom. los ntawm kev hloov lub xeev ua haujlwm ntawm lub tsheb. 1 Thaum nws xav tias lub tshuab hluav taws xob tsis tsim hluav taws xob, lub tshuab hluav taws xob tsis tuaj yeem raug tshem tawm, thiab lub tshuab hluav taws xob tuaj yeem kuaj pom ntawm lub tsheb los txiav txim siab seb puas muaj qhov txhaum. 1.1 Multimeter voltage profile test Tig lub multimeter knob mus rau 30V DC voltage (los yog siv cov profile tsim nyog ntawm ib tug dav DC voltmeter), txuas tus cwj mem liab rau lub tshuab hluav taws xob "armature" txuas kab, thiab txuas tus cwj mem dub rau lub tsev, yog li ntawd lub cav khiav saum nruab nrab ceev, qhov ntsuas tus nqi ntawm 12V hluav taws xob yuav tsum yog li 14V, thiab tus nqi hluav taws xob ntawm 24V hluav taws xob yuav tsum yog li 28V. Yog tias qhov ntsuas hluav taws xob ntsuas yog lub roj teeb voltage, nws qhia tias lub tshuab hluav taws xob tsis tsim hluav taws xob. 1.2 External ammeter detection Thaum tsis muaj ammeter ntawm lub dashboard ntawm lub tsheb, ib tug sab nraud DC ammeter yuav siv tau rau kev kuaj. Ua ntej tshem tawm lub tshuab hluav taws xob "armature" connector hlau, thiab tom qab ntawd txuas tus ncej zoo ntawm DC ammeter nrog thaj tsam li 20A rau lub tshuab hluav taws xob "armature", thiab cov xaim tsis zoo rau saum toj no disconnecting connector. Thaum lub cav khiav siab tshaj qhov nruab nrab ceev (tsis tas siv lwm yam khoom siv hluav taws xob), lub ammeter muaj 3A ~ 5A them cov cim qhia, qhia tias lub tshuab hluav taws xob ua haujlwm li qub, txwv tsis pub lub tshuab hluav taws xob tsis tsim hluav taws xob. 1.3 Test lub teeb (lub teeb lub tsheb) txoj kev Thaum tsis muaj multimeter thiab DC meter, lub tsheb teeb tuaj yeem siv los ua lub teeb ntsuas ntsuas. Weld nyob ntawm qhov tsim nyog ntev mus rau ob qhov kawg ntawm lub teeb thiab txuas ib qho hlua khi rau ob qho kawg. Ua ntej kev sim, tshem tawm tus neeg xyuas pib ntawm lub tshuab hluav taws xob "armature" connector, thiab tom qab ntawd clamp ib kawg ntawm lub teeb ntsuas rau lub tshuab hluav taws xob "armature" connector, thiab coj mus rau lwm qhov kawg ntawm cov hlau, thaum lub cav khiav ntawm nruab nrab ceev, kuaj lub teeb qhia tias lub tshuab hluav taws xob ua haujlwm ib txwm ua, txwv tsis pub lub tshuab hluav taws xob yuav tsis tsim hluav taws xob.
Yuav ua li cas kho lub tsheb alternator
Cov txheej txheem txij nkawm ntawm automotive alternator feem ntau suav nrog kev npaj, disassembly, tshuaj xyuas, kho, sib dhos, sim thiab hloov cov kauj ruam. cov
Kev Npaj: Xyuas kom meej tias lub tshuab hluav taws xob tau raug kaw tag nrho kom tsis txhob muaj hluav taws xob hluav taws xob thaum tu. Npaj cov cuab yeej uas yuav tsum tau muaj, xws li wrenches, ntswj ntsia hlau, thiab multimeters, thiab hnav khaub ncaws tiv thaiv thiab hnab looj tes.
Disassembly: tua lub ignition hloov ntawm lub tsheb thiab disconnect lub roj teeb tsis zoo. Tshem cov bolts nyob rau hauv ib qho kev txiav txim, saib xyuas kom tsis txhob poob ib qho twg, thiab muab cov khoom tshem tawm hauv qhov chaw huv thiab yooj yim.
Kos : Siv ib lub multimeter los ntsuas qhov voltage thiab magnetic teb zog ntawm lub alternator. Tshawb xyuas cov kabmob thiab cov txhuam hniav kom hnav thiab hloov lawv yog tias tsim nyog. Nyob rau tib lub sij hawm, xyuas seb cov pa roj carbon txhuam bracket thiab daim ntawv conductive puas puas lawm, thiab ua cov kev kho tsim nyog.
Kev kho: Raws li qhov kev puas tsuaj tau pom, ua haujlwm kho qhov tsim nyog, xws li hloov cov kabmob hnav, cov txhuam hniav thiab lwm yam.
Kev sib dhos : Txhim kho cov khoom tshem tawm raws li cov khoom qub, thiab xyuas seb cov bolts puas tau txuas ntxiv kom ntseeg tau tias lawv tsis xoob. Reinstall qhov tsis zoo cable ntawm lub roj teeb.
Kev sim thiab kev hloov kho : Siv lub tshuab multimeter los xyuas dua seb qhov voltage thiab magnetic teb lub zog yog qhov qub. Xyuas seb lub alternator puas ua haujlwm li qub, thiab saib seb lub roj teeb puas raug them. Yog tias pom muaj qhov tsis txaus ntseeg, yuav tsum tau hloov kho thiab kho yuav tsum tau ua.
Los ntawm cov kauj ruam saum toj no, lub tsheb alternator tuaj yeem kho tau zoo thiab tswj xyuas kom nws ua haujlwm zoo thiab ua kom muaj kev ruaj ntseg ntawm lub tsheb hluav taws xob.
