Voltage regulator - yuav ua li cas kom tsis txhob poob?

Kev tswj qhov hluav taws xob yam uas txhawb nqa lub tsheb roj teeb. Hluav taws xob hauv lub tsheb yog tsim los ntawm lub tshuab hluav taws xob. Lub regulator tsis tas yuav tuav tib lub voltage. Nws nyob ntawm lub cav ceev. Txoj cai ntawm tus ntiv tes xoo yog tias 0,5V yuav tsum tsis pub tshaj. Oscillations tuaj yeem ntxhov siab lub tshuab hluav taws xob. Cov khoom no feem ntau tuaj yeem overheat, piv txwv li thaum cov cua sov thiab cov rooj zaum rhuab tau qhib tib lub sijhawm. Yuav ua li cas kom tsis txhob muaj teeb meem nrog lub tshuab hluav taws xob voltage regulator thiab saib xyuas nws? Nyeem tsab xov xwm!

Kev ua haujlwm raug ntawm qhov ntsuas hluav taws xob hauv lub tsheb

Cov cuab yeej yuav tsum tswj xyuas qhov voltage tsis tu ncua, uas yog tsim los ntawm lub tshuab hluav taws xob lossis lub tshuab hluav taws xob. Yog hais tias tus regulator tuav tib lub voltage thaum lub cav idling thiab nyob rau hauv kev kub ceev, qhov no yog ib tug kos npe rau hais tias nws ua hauj lwm zoo. Kev them nyiaj yug voltage V generator voltage regulator yuav tsum nyob nruab nrab ntawm 14,0 thiab 14,4 volts. Nws yuav tsum nco ntsoov tias qhov ntsuas no nyob ntawm qhov xwm txheej ntawm lub tsheb. Lub tsheb loj dua, qhov voltage yuav poob ntau dua. Cov khoom no yuav tsum tau hloov txhua ob peb xyoos thiab kuaj xyuas ntau zaus.

Voltage regulator - yuav kuaj li cas?

Nws yooj yim vim txhua yam koj xav tau yog voltmeter lossis multimeter. Lub txee muaj nyob rau hauv txhua lub tsheb muag khoom thiab txawm nyob hauv cov khw loj loj. Cov cuab yeej no tsis kim thiab yuav yooj yim siv. Nco ntsoov tias lub 'meter' yuav tsum raug muab tso rau kom raug, vim tias ua tsaug rau qhov no koj yuav pom qhov kev ntsuas kev ntseeg tau ntawm voltage regulator.

Yuav ntsuas li cas?

Koj tuaj yeem ua qhov ntsuas hluav taws xob hauv ob peb kauj ruam:

• txheeb xyuas qhov ntws ntawm qhov tam sim no ntawm lub tshuab hluav taws xob thiab lub regulator;
• teeb tsa tus nqi DC tsim nyog ntawm lub ntsuas;
• ntsuas qhov voltage ob peb zaug nyob rau hauv txawv configurations;
• sib piv cov txiaj ntsig nrog cov ntaub ntawv tsim khoom.

Cov txiaj ntsig tau qhia hauv lub tsheb tus tswv phau ntawv.

Lub tshuab hluav taws xob yog ib feem tseem ceeb hauv lub tshuab

Lub tshuab hluav taws xob muaj nws lub ntsiab windings hauv stator es tsis yog lub rotor. Txij li thaum lub roj teeb yuav tsum tau them rov qab, nws yog nruab nrog silicon diode rectifier. Lub generator muaj ib tug built-in voltage regulator. Nov yog cov lus qhia yuav ua li cas txuas lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob:

• txuas lub voltage regulator rau cov khoom sib txuas thiab xyuas cov tshuab hluav taws xob ua ntej kev teeb tsa;
• tom qab tig tus yuam sij, txuas lub zog;
• muab lwm yam kev sib cuag ntawm lub tshuab hluav taws xob txhuam;
• txuas lub teeb qhia kev them nyiaj los yog relay rau lub voos xwmfab kom teeb liab them.

Txuas lub tshuab hluav taws xob voltage regulator tsis nyuaj thiab tuaj yeem ua nrog koj tus kheej tes hauv tsev.

Txhim kho lub tshuab hluav taws xob

Thaum txhim kho lub tshuab hluav taws xob koj yuav tsum: 

• muab lub tshuab hluav taws xob tso rau hauv qhov chaw ntawm lub tshuab hluav taws xob thiab ruaj ntseg;
• txhim kho txoj siv sia ntawm lub pulley;
• kom nruj txoj siv sia siv lub tensioner;
•  Txuas cov hlua hluav taws xob mus rau qhov pib thiab ceeb toom teeb.

Kev ua tsis tiav ntawm qhov ntsuas hluav taws xob hauv hluav taws xob

Qee zaum qhov voltage regulator tsis ua haujlwm. Cov tsos mob tshwm sim los ntawm qhov tseeb tias tus regulator tuav voltage tsuas yog nyob rau hauv qis engine speeds. Raws li lub zog ntxiv, tej zaum yuav muaj hluav taws xob poob sai sai. Yuav ua li cas koj yuav soj ntsuam qhov tsis ua hauj lwm ntawm lub voltage regulator? Cov tsos mob - qhov sib txawv ntawm kev ua haujlwm ntawm qhov nrawm nrawm. Muaj cov xwm txheej nyob rau hauv uas, thaum lub sij hawm intensive engine lag luam, lub voltage yog tswj kom zoo kawg nkaus, tab sis nyob rau hauv tsawg speeds nws yuav luag tsis pom.

Hlawv tawm voltage regulator - cov tsos mob

Koj tuaj yeem paub txog lub tshuab hluav taws xob overheated los ntawm burnt-tawm rectifier diodes. Overheating tuaj yeem tshwm sim vim kev sib dhos yuam kev, i.e. kev txuas tsis raug ntawm cov roj teeb cables. Lub diodes lub luag hauj lwm rau them lub roj teeb hlawv tawm thaum muaj ib tug tam sim ntawd luv luv Circuit Court. Yog li ntawd, tag nrho cov regulator ua tsis tiav.

Hlawv stator

Lub stator yog ib feem ntawm lub alternator uas tsim hluav taws xob. Nws tuaj yeem hlawv tawm vim qhov hnyav ntawm lub tshuab hluav taws xob. Lub load ib txwm ua rau overheating. Qhov tshwm sim yog kev puas tsuaj ntawm rwb thaiv tsev thiab luv luv rau hauv av.

Generator voltage regulator - cov cim ntawm tsis ua hauj lwm

Lwm qhov kos npe ntawm qhov tawg lub tshuab hluav taws xob voltage regulator Txoj siv tawv kuj tuaj yeem tawg. Cov khoom no tuaj yeem raug puas tsuaj yog tias sib dhos tsis raug, tab sis feem ntau tawg vim muaj hnub nyoog. Yog tias txoj siv tawv tawg, tsis muaj teeb meem loj, vim nws txaus los hloov nws nrog ib qho tshiab. Qee lub sij hawm koj yuav tsum tau xyuas seb qee cov ntsiab lus ntawm lub kaw lus raug thaiv tom qab siv txoj siv sia. Nyob rau hauv cov ntaub ntawv no, nws yog ib qhov tsim nyog los txiav txim seb dab tsi ua rau txoj siv sia tawg thiab kho qhov teeb meem sai li sai tau.

Yuav tus tshiab voltage regulator - koj yuav tsum paub dab tsi?

Yog tias cov khoom no tsis ua haujlwm, tib txoj hauv kev tawm yog hloov lub voltage regulator. Koj yuav tsum yuav cov khoom qub uas yuav haum koj lub tsheb kom raug thiab yuav tsis ua rau nws puas. Kev hloov pheej yig tsuas yog khaws cov hluav taws xob rau lub sijhawm luv luv thiab yuav tsum tau hloov pauv sai, yog li cov nyiaj khaws cia tsuas yog pom tseeb.

Thaum hloov khoom siv, koj yuav tsum nco ntsoov xaiv cov khoom lag luam zoo uas yuav ua kom tag nrho cov khoom siv hluav taws xob ua haujlwm zoo. Koj yuav tsum tsis txhob khom rau cov khoom uas tsis yog thawj zaug, vim tias tsis ntev koj yuav tau hloov lub regulator dua. Yog tias koj muaj teeb meem them nqi, qhov teeb meem yuav tsis yog nrog lub alternator, tab sis nrog lub voltage regulator., Nws tsim nyog kuaj xyuas tsis tu ncua.
