Kev daws teeb meem 101

Phom fuse lossis swb relay?

Thaum cov hluav taws xob tivthaiv nres tsheb ua haujlwm, qhov teeb meem feem ntau tuaj yeem nkag mus rau hauv lub fuse. Lo lus nug yog, uas feem ua tsis tiav? Ntawm no yog cov tswv yim, kauj ruam - by - fuse yog tias koj muaj qhov tsis zoo lossis tsis zoo relay.

Koj tus tswv phau phau ntawv yog koj cov cuab yeej tseem ceeb tshaj plaws ntawm no. Nws muaj cov duab kos ntawm cov ntaub ntawv fuse (feem ntau yog ib lub cav ntoo thiab ib sab hauv lub txee) uas fuse thiab Relay tswj uas Circuit Court.

Kauj ruam 1: Khij lub fuse

Txheeb xyuas lub fuse yog ib txwm ua thawj thiab yooj yim. Nws yuav tsum tau cov cuab yeej tsawg heev thiab tuaj yeem ua tau hauv feeb.

Nrhiav cov thawv fuse yog siv koj tus tswv phau ntawv.

Siv daim duab kos rau sab hauv ntawm lub fuse cov ntaub ntawv npog lossis hauv phau ntawv qhia rau cov khoom siv uas tsis ua haujlwm (piv txwv li CIG, "" H / LP RH ").

Nrog rau lub tsheb nres tau muab tua, siv lub fuse puller (feem ntau suav nrog hauv lub fuse)}- lub taub ntswg rau maj mam rub lub fuse ncaj tawm ntawm nws qhov.

Visually soj ntsuam lub fuse. Tuav nws mus txog ntawm lub teeb thiab saib ntawm cov ntaub ntawv me me hauv. Nyob rau hauv ib qho fuse zoo, qhov no s- Daim hlau zoo li yuav raug lawm. Hauv lub tshuab fuse, cov hlau yuav tawg lossis muaj qhov sib txawv pom, qee zaum nrog tsaus, hlawv smudge sab hauv lub tsev yas.

Rau qhov kev ntsuas kev sib cav, siv ntau txoj kev sib txuam nrog hom txuas ntxiv (feem ntau nws muaj lub suab nrov suab). Kov cov haujlwm rau txhua ntawm ob qho ntawm ob lub hlau tuaj rau sab saum toj ntawm lub fuse. Lub zog fuse yuav muaj kev txuas ntxiv thiab multimeter yuav gleep. Ib lub tshuab tshuab fuse yuav pom kev qhib Circuit Court thiab yuav tsis muaj beep.

Yog tias lub fuse yog tshuab, koj yuav pom koj qhov teeb meem. Txawm li cas los xij, nco ntsoov tias fuses tshuab rau ib qho laj thawj. Yog tias hloov cov fuse buse

Kauj ruam 2: Kuaj cov relay

Yog tias lub fuse yog qhov zoo, tus neeg phem tom ntej no yog cov relay. Kuaj cov relay yog kev koom tes me ntsis, tab sis muaj ob peb tus ntse tricks koj tuaj yeem siv.

Txheeb xyuas qhov tseeb relay rau cov Circuit Court siv cov duab fuse.

Ua qhov "nyem sim." Nov yog qhov yooj yim tshaj tawm kos duab. Muaj ib tug phooj ywg ua haujlwm hloov rau qhov tsis- Ua haujlwm nruab thiab tawm, hon, hones} Hon, hon, hon, hon, hon, hon, hon, hon, hon, hones Lub relay noj qab haus huv yuav ua rau ib qho tsaus muag tab sis muaj qhov sib txawv "nyem" suab thiab koj yuav xav tias nws ua tiav. Yog tias koj hnov ​​thiab xav tias nias, tus relay tswj yog yuav yuav ua haujlwm. Yog tias tsis muaj Nyem, tus xa tawm yog qhov tsis zoo, lossis nws tsis tau txais lub teeb liab los ntawm tus tes hloov.

Sim cov "sib pauv ntsuas." Qhov no yog qhov zoo tshaj plaws DIY kuaj mob. Saib rau lwm lub relay hauv lub fuse uas muaj tib tus lej thiab tus lej PIN. Feem ntau, tsis yog - tseem ceeb tshaj plaws zoo li lub raj kub yuav siv ib qho tseem ceeb ib yam li cov roj twj tso kua mis. Nrog rau lub tsheb ignition tag nrho tawm, rub tus neeg phem rov qab thiab sib pauv nws nrog qhov zoo tib yam, paub} zoo relay los ntawm lwm qhov Circuit. Tam sim no, sim qhov tsis - ua haujlwm sib xyaw ua haujlwm dua. Yog tias nws dheev ua haujlwm, koj tau lees tias tus thawj relay yog faulty. Yog tias nws tseem tsis ua haujlwm, cov teeb meem nyob rau lwm qhov hauv Circuit Court, xws li hloov lossis cov xaim. Nco ntsoov muab tso rau qhov zoo relay rov qab rau hauv nws cov chaw qub.

Rau cov neeg siv siab, ib qho "xeem yuam kev" muab cov lus teb kom meej. Nrog rau cov relay tshem tawm ntawm lub tsheb, koj tuaj yeem siv 12v lub zog siv roj teeb (zoo li lub roj teeb lossis lub zog ua ntu fais fab) los siv zog rau kev tswj hwm lub pins (85 thiab 86). Ib tug zoo relay yuav nyem. Thaum nws yog energized, koj tuaj yeem siv ntau sib deev los kuaj xyuas tias qhov siab- fais fab tuag (pins} Power Hwj chim.

Cov kev ua txhaum cai

Vim li cas relays tsis "tshuab"

Nws yog cov lus ib yam hauv cov chaw sib tham hauv tsheb thiab chaw nres tsheb: "Kuv cov roj twj tso kua mis relay thw." Thaum txhua tus neeg nkag siab lub ntsiab lus - Cov relay ua tsis tiav- nws yog hom tsis ncaj ncees lawm.

Raunays tsis yog "tshuab" nyob rau hauv tib txoj kev uas fuses ua. Lub fuse yog cov khoom siv thermal tsim kom poob poob los tiv thaiv ib puag ncig. Ib tug relay yog ib lub tshuab hloov khoom, thiab nws tsis zoo li lwm qhov hloov.

Nkag siab qhov sib txawv no yog qhov tseem ceeb rau kev kuaj mob. Yog tias koj tab tom nrhiav "tshuab" relay nrog lub qhov cub hlawv lossis tawg ua ntej, koj yuav tsis pom ib qho. Ib tug ua tsis tau relay feem ntau zoo li zoo ib yam rau ib tug ua haujlwm ib sab nraud. Nws ua tsis tiav yog sab hauv thiab hauv hluav taws xob lossis tshuab.

Yuav ua li cas reeps tiag tiag swb

Hloov chaw ntawm lub tshuab tawg, rov qab ua tiav hauv qee txoj kev, txhua tus tsim cov tsos mob sib txawv.

Coil tsis ua hauj lwm: cov hlau nyias nyias qhwv ib ncig ntawm cov hluav taws xob hluav taws xob tuaj yeem tsoo lossis hlawv. Thaum qhov no tshwm sim, kev tswj hwm hluav taws xob tau tuag. Ua ntawv thov lub hwj chim yuav tsis tsim daim teb sib nqus, thiab cov relay yuav tsis "nyem" lossis qhib. Cheebtsam nws tswj tau yuav tsis qhib.

Hu rau pitting thiab vuam: Qhov no yog hom tsis ua hauj lwm. Txhua txhua lub sijhawm relay tig rau thiab tawm, lub tshuab hluav taws xob me me tshwm sim ntawm lub siab-} muaj zog tiv tauj. Ntau tshaj ntau txhiab lub voj voog, qhov arc no mus rau qhov chaw sib chwv, ua rau pitting. Qhov no tsim kev sib txuas tsis zoo, ua rau kev ua haujlwm sib txawv lossis ua tiav tsis tiav xa lub zog. Conversely, ib qho kev nce qib tam sim no tuaj yeem tau txais cov neeg sib cuag kom lawv lub cev yaj thiab weld lawv tus kheej ua ke. Qhov no ua rau muaj kev xa tawm uas tau nyam nyob rau hauv "ntawm" txoj haujlwm, txhais tau tias cov khoom siv roj (zoo li cov twj roj (zoo li thaum tus yuam sij tshem tawm.

Neeg kho tshuab tsis ua hauj lwm: Ua ib qho cuab yeej siv tshuab, ib qho relay tuaj yeem tsuas yog hnav. Lub caij nplooj ntoo hlav sab hauv uas rub lub qhib qhib tuaj yeem ua kom tsis muaj zog lossis tawg, lossis kev txav ua armature tuaj yeem nyam. Qhov no tuaj yeem ua rau cov relay ua rau mus tas li lossis tawm.
