Thaum lub roj teeb ntawm lub tsheb lossis maus taus tsis zoo los yog them rov qab, yog li hais, ua ntej ntawm txhua yam koj yuav tsum tau xyuam xim rau lub tshuab hluav taws xob relay. Tau kawg, qhov teeb meem no tuaj yeem tshwm sim los ntawm ntau yam laj thawj, tab sis feem ntau nws yog nyob rau hauv relay. Tab sis yuav ua li cas xyuas cov relay nrog ib tug multimeter? Wb tham txog qhov ntawd.

Cov khoom no yog tsim los tiv thaiv lub roj teeb thiab txuas nws lub neej rau ntau xyoo. Thiab tag nrho cov no txawm nws compactness. Yog li ntawd, yog tias koj mam li nco dheev pom tias lub tsheb tsis pib zoo tom qab hmo ntuj, pom cov smudges dawb thiab tsis zoo pib ua haujlwm, ces nws yog lub sijhawm los nce hauv qab hood. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum paub yuav ua li cas los xyuas qhov pib relay nrog lub multimeter, vim hais tias yog txhua yam nyob rau hauv raws li nws yog, lub roj teeb yuav "tuag" sai sai.

Definition

Ua ntej koj txheeb xyuas cov relay nrog multimeter, koj yuav tsum nkag siab tias nws yog dab tsi - relay. Qhov no yog ib qho cuab yeej tsim los tswj qhov tam sim nolub tsheb lub alternator, uas tiv thaiv nws los ntawm recharge lub roj teeb. Yog li ntawd, vim hais tias ntawm cov khoom no, roj teeb kav ntev.

Los ntawm thiab loj, lub relay yog ib qho hluav taws xob stabilizer uas tsis tso cai rau qhov hluav taws xob ntau dua 14.5 volts. Qhov ntsuas no yog qhov tseeb heev thiab yog qhov yuav tsum tau rau txhua hom tshuab. Txawm li cas los xij, muaj ntau hom relays.

Type

Hais lus, tsuas muaj ob hom, thiab lawv ua haujlwm ntawm tib lub hauv paus ntsiab lus - lawv nce lossis txo qhov voltage rau qhov ntsuas qhov xav tau - 14.5 Volts. Thawj hom - lub relay yog ua ke nrog txhuam los ua ke. Nws feem ntau yog txuas nrog lub tshuab hluav taws xob nws tus kheej, thiab lub relay nws tus kheej yog nyob rau hauv lub tsev uas cov txhuam hniav muab tso rau.

Kuj, lub relay tuaj yeem ua tau raws li cov khoom sib cais, uas yog ntsia rau ntawm lub cev lub tsheb, thiab cov xov hlau los ntawm nws mus rau lub tshuab hluav taws xob, thiab tom qab ntawd mus rau lub roj teeb.

Cov rooj plaub ntawm ob hom relays yog ntim nrog kua nplaum lossis sealant, thiab lawv tsis kho txhua. Yog li, yog tias peb xyuas cov solenoid relay nrog lub multimeter thiab nws hloov tawm tias nws tsis ua haujlwm, ces peb yuav tau yuav ib qho tshiab nrog kev lav. Hmoov zoo, nws yog pheej yig, tshwj xeeb tshaj yog rau domestic VAZ tsheb. Yog li ntawd, nws yog qhov yooj yim dua thiab yooj yim dua los yuav lub relay tshiab, tsis yog hack tus qub.

Yog tias nws "tuag", ces lub roj teeb yuav rov pib dua. Qhov no txhais tau tias nws yog lub sij hawm los hloov lub relay. Tab sis rau qhov no nws yog ib qho tseem ceeb kom paub yuav ua li cas mus xyuas lub relay nrog ib tug multimeter, vim hais tias peb yuav tsum paub hais tias nws yog nyob rau hauv nws, thiab tsis yog nyob rau hauv lwm qhov chaw ntawm lub generator. Muaj tsawg kawg yog ob txoj kev xaivchecks: tsis tau tshem tawm ntawm lub tsheb thiab nrog tshem tawm.

Yuav ua li cas kuaj lub tshuab hluav taws xob relay nrog multimeter yam tsis tau tshem tawm ntawm lub tsheb?

Cov cim qhia ntawm tus tswj tsis ua haujlwm tau pom meej meej. Tshwj xeeb yog tias nws khov sab nraud. Lub roj teeb yuav ib txwm yog undercharged lossis overcharged. Hauv thawj kis, lub roj teeb tsis muaj zog yog qhov yooj yim los txiav txim siab seb lub tshuab pib tig lub cav li cas. Nws yuav NW nyuam qhuav tig nws, thiab tsis muaj txiaj ntsig. Qee zaum thaum koj tig tus yuam sij, tsis muaj dab tsi tshwm sim, thiab lub teeb ntawm lub vaj huam sib luag tawm mus.

Recharge lub roj teeb yog xyaum tsis txawv. Tib yam yuav tshwm sim, ntxiv rau cov electrolyte los ntawm cov kaus poom roj teeb yuav boil. Koj tuaj yeem txiav txim siab qhov nyiaj dhau los ntawm kev txo qis hauv cov txhab nyiaj electrolyte. Raws li qhov tshwm sim ntawm evaporation, ib txheej dawb kuj tuaj yeem tsim rau saum lub roj teeb. Lub cev qhov chaw hauv qab lub roj teeb kuj tseem tuaj yeem muaj xim dawb. Feem ntau, nrog cov tsos mob zoo li no, cov neeg tsav tsheb xav tias lub roj teeb puas lawm, tab sis qhov tseeb, txhua yam yog nyob rau hauv kev txiav txim nrog nws, thiab qhov teeb meem yog nyob rau hauv relay-regulator, thiab nws yog nyob ntawm nws uas koj yuav tsum tau xyuam xim ua ntej ntawm tag nrho cov. Tab sis rau qhov no koj yuav tsum paub yuav ua li cas los xyuas cov relay nrog ib tug multimeter.

Nws yooj yim ua. Ua li no, coj peb multimeter thiab teem nws mus rau voltmeter hom. Nrog nws, peb tuaj yeem ntsuas qhov voltage ntawm lub roj teeb terminals nrog lub cav khiav. Nco ntsoov tias thaum lub cav tawm, qhov voltage ib txwm yuav tsum nyob rau hauv thaj tsam ntawm 12.4-12.7 V. Yog hais tias, piv txwv li, qhov voltage yog 12 V, ces lub roj teeb yuav tsum tau them thiab qhov ua rau yuav tsum tau saib rau.undercharged.

Ntaus kev nyuaj siab

Yog li, pib lub cav, teeb tsa lub multimeter rau 20 V voltmeter hom thiab txuas nws cov kev sojntsuam mus rau lub davhlau ya nyob twg. Yog hais tias qhov voltage yog nyob rau hauv cheeb tsam ntawm 13.2-14 V, ces txhua yam nyob rau hauv kev txiav txim nrog lub roj teeb. Ua kom lub cav ceev rau 2000-2500. Nyob rau hauv cov ntaub ntawv no, qhov voltage yuav tsum tau nce mus rau kwv yees li 13.6-14.3 V, uas kuj nyob rau hauv ib txwm muaj. Tam sim no nce qhov nrawm mus rau 3500, thiab qhov hluav taws xob yuav tsum nce mus rau 14-14.5 V. Kwv yees li ntawm cov cim no, yuav tsum muaj qhov hluav taws xob hauv lub roj teeb ua haujlwm nrog kev ua haujlwm relay.

Cov txiaj ntsig txawv txav ntawm lub multimeter

Yog tias qhov tseem ceeb sib txawv ntawm qhov taw qhia nce lossis nqis, qhov no qhia tias qhov ua haujlwm tsis zoo ntawm lub relay. Piv txwv li, yog tias qhov hluav taws xob poob mus rau 12 V nrog kev nce hauv lub cav ceev, ces ib yam dab tsi tsis ncaj ncees lawm ntawm no. Tsis tas li ntawd, qhov nce ntawm qhov hluav taws xob mus rau 15-16 V qhia tias muaj kev ua haujlwm tsis zoo ntawm cov relay-regulator.

Power surges tsis yog ib txwm qhia txog kev ua haujlwm tsis zoo, tab sis feem ntau. Qee zaum lub tshuab hluav taws xob nws tus kheej tuaj yeem ua tsis tiav. Txawm li cas los xij, yog tias muaj hluav taws xob tshwm sim, koj yuav tsum xub hloov lub regulator, thiab yog tias qhov teeb meem tshwm sim, ces koj yuav tsum hloov lub tshuab hluav taws xob thiab xyuas tag nrho cov system.

Tshuaj xyuas cov sib xyaw ua ke- tswj hwm

Yog tias cov txhuam hniav sib dhos ua ke nrog cov relay, lub alternator yuav tsum tau muab tshem tawm mus kuaj. Ua ntej koj yuav tsum tau xyuas cov sib xyaw relay-regulator Circuit Court, uas yog siv niaj hnub no ntawm ntau lub tsheb txawv teb chaws thiab txawm nyob hauv tsev.machines.

Ua li no, koj yuav tsum tau tshem tawm thiab disassemble lub tshuab hluav taws xob, vim tias chav tsev peb xav tau txuas nrog lub tshuab hluav taws xob, nrog rau cov txhuam hniav mus. Peb tab tom nrhiav rau "qhov rais" rau cov txhuam hniav ntawm lub tshuab hluav taws xob, tshem tawm cov ntsia hlau txuas, tshem tawm cov txhuam txhuam thiab ntxuav nws. Nws feem ntau yog npog hauv graphite hmoov av.

Tam sim no peb yuav tsum tau sib sau ua ke ib lub voj voog tshwj xeeb uas siv cov khoom siv hluav taws xob tswj tau. Peb kuj xav tau lub roj teeb, vim tias lub hwj chim lossis lub charger tsis ua haujlwm yam tsis muaj nws. Yog li, peb txuas lub charger rau lub roj teeb thiab nyob rau tib lub sijhawm mus rau lub relay-regulator, thiab mus rau tom kawg peb kuj txuas lub teeb 12 V.

Nrog rau qhov kev sib txuas no, lub teeb yuav teeb - qhov no yog qhov qub, vim tias cov txhuam hniav sib dhos yog tus neeg xyuas pib, thiab nyob rau hauv ib qho chaw ntsiag to, qhov voltage ntawm no yog 12.7 V. Tam sim no peb yuav tsum tau nce qhov voltage ntawm lub charger. mus rau 14.5 V. Lub teeb, thaum qhov no mus txog qhov taw qhia yuav tsum tawm mus. Tom qab tag nrho, 14.5 V yog qhov "txiav tawm" ntawm kev loj hlob voltage. Thiab yog tias lub teeb tawm mus, nws txhais tau hais tias lub relay tau ua haujlwm, thiab hauv txoj cai nws ua haujlwm.

Txwv tsis pub, yog tias qhov hluav taws xob nce mus txog 15-16 V, thiab lub teeb ci, nws txhais tau tias lub relay tsis txiav tawm. Hauv qhov no, nws yuav tsum tau hloov nrog ib qho tshiab.

Tam sim no koj paub yuav ua li cas kuaj cov regulator relay nrog multimeter, thiab koj tuaj yeem ua koj tus kheej.
