Roj teeb uas them lub teeb lit: yuav ua li cas?

Yog hais tias lub teeb yog lit roj teeb them, tus neeg tsav tsheb pib txhawj. Thiab ib tug yog vim li cas rau qhov no loj - roj teeb muaj peev xwm yog tsis zoo li yuav tsum tau txaus los mus kov yeej ib tug tseem ceeb nqi. Thiab yog vim li cas hais tias zes lub teeb, yuav ua tau tsis ua hauj lwm ntawm lub generator, roj teeb txhaum nyob rau hauv lub onboard network. Tag nrho tej yam uas muaj nqis coj zoo dua, yog li ntawd nyob rau hauv cov ntaub ntawv ntawm ib tug tsi xam pom qhov teeb meem no sai sai tshem tawm breakage. Yuav kom tswj cov muaj xwb nyob rau hauv cov roj teeb yog ntsia tau rau hauv lub dashboard tshwj xeeb teeb. Nws teeb yog hais tias muaj yog tsis tau them nqi.

Raws li cov generator yog khiav?

Ua ntej koj yuav to taub vim li cas lub teeb roj teeb uas them qhov taw qhia, koj yuav tsum to taub lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub generator. Nyob rau tsheb muaj ob tug hwj chim khoom siv. Ib tug generator thiab ib lub roj teeb. Lawv muaj kev cob cog nyob rau hauv thaum uas tig mus. Yog li ntawd, thaum lub cav generator khoom siv ib tug voltage rau lub roj teeb thiab tsub nws. Thiab muaj ib tug feature. Txawm li cas los ntawm tus xov tooj ntawm revolutions ntawm lub voltage generator tso zis yog ib txwm zoo li qub.

Yuav kom tswj cov teeb relay-regulator. Nyob rau cov laus lub tsheb siv tsim ntawm lub electromechanical hom. Nyob rau hauv niaj hnub semiconductor siv heev dua lwm yam. Lub teeb, uas yog kev txhawb nyob rau hauv lub dashboard, yog muaj nyob rau hauv lub voltage regulator Circuit Court. Nws yog ib, nyob rau hauv qhov tseeb, ib tug fuse. Yuav kom to taub, koj yuav tsum kom huv si xyuas lub hauv paus ntsiab lus ntawm cov voltage relay tswj.

voltage regulator

Lub ob generators winding - rotor thiab stator. Wherein thawj excitation winding ua zog. Nws yog tsim nyog yuav tau nco qab lub hom phiaj: tsis tsiv magnetic teb yuav tsis ua kom muaj hluav taws xob. Thiaj li, txaus mus pub cov rotor winding voltage kom tau ib tug sib nqus teb. Zoo, txij thaum lub rotor - ib tug tsiv ib feem ntawm lub fais tshuab, nws yog tseeb hais tias cov magnetic teb rotates. Thiab yog hais tias tej zaum muaj teeb cov roj teeb them nyiaj qhia, nws qhia tau hais tias muaj yog ib tug me me kho raws nyob rau hauv lub generator.

Tab sis yog vim li cas teem lub voltage regulator Circuit Court yog nyob rau hauv lub teb mov? Tom qab tag nrho, nws yog tsim nyog los tsim ib tug stabilization nyob rau hauv lub stator Circuit Court. Nws yog ib, tab sis nws yog ib nqi nco ntsoov tshawb xav: qhov ntau ntawm cov magnetic teb nyob rau hauv lub qhov zis voltage. Nws yog heev yooj yim. Txaus stabilized hwj chim Circuit Court ntawm lub rotor winding mus rau lub tso zis hloov mus hloov los tsis. Nws yog yooj yim npaum li mus nqa tawm lub stabilization ntawm tsawg tsaws ntxhee, es loj (tej zaum yuav mus txog ib co ntawm kaum amperes).

Nrhiav breakages

Piv txwv, tom qab pib lub cav, koj pom tias lub roj teeb uas them lub teeb illuminates. Vaz cuam tshuam los ntawm qhov teeb meem no, thiab nws yog ib yam rau tej qauv. Cov nram qab no Cheebtsam yuav tsum tau soj ntsuam:

1. Lub voltage regulator piav saum toj no. Nyob rau ib txhia lub tsheb tej zaum yuav mounted nyob rau hauv lub hood thiab tsis pub dhau lub generator.
2. Diode choj. Tau ua hauj lwm ntawm ib tug los yog ntau tshaj semiconductors.
3. generator tsav siv. Nws yuav ncav us txog los yog phem nws tshwm sim breakage, slippage. Yog hais tias koj yuav hnov cov xuav, nws tseem tau mus txiav txim rau ib tug kabmob tsis ua hauj lwm nyob rau hauv pem hauv ntej npog.

Yog vim li cas tej zaum yuav kuj ua tau ib tug hlau breakage los yog tsis zoo hu. Kos rau lub thawj kauj ruam yog nqa tawm mus los ntawm "+" mus rau lub alternator voltage regulator. Heev feem ntau nws yog oxidized, coated nrog ib tug txheej ntawm hmoov av. Tshem tawm cov txhuam yas dhos thiab txhuam coj tus nqi. Yog hais tias nws yog ntau, nws yog tsim nyog los hloov. Nco ntsoov tias nyob rau hauv cov tsheb uas cov voltage regulator thiab tus txhuam ua ke rau hauv ib tug tsev. Lwm yog vim li cas - tsis ua hauj lwm nyob rau hauv lub ignition. Tab sis qhov no tsis ua hauj lwm yog nrog los ntawm cov fact tias ntau teeb ci ntsa iab nyob rau hauv lub twj paj nruag vaj huam sib luag.

Cov cuab yeej rau kho

Nyob rau hauv cov kev tshwm sim hais tias teeb ntawm lub ceev roj teeb uas them teeb yog yuav mus yuav tus cov ntaub ntawv siv slippage vim tsis muaj zog nro. Tab sis yog hais tias yog tag nrho cov cai, koj yuav tsum rau sab caj npab rau lawv tus kheej nrog rau cov nram qab no cov cuab yeej:

• Multimeter (dua li pointer voltmeter nrog ib tug broad scale).
• Control teeb rau 12 volts thiab 2-3 watt.
• Pav ca thiab Phillips screwdrivers.
• Ciaj, ntwav txhuam ntoo, riam.

Nrog rau cov cuab yeej rau tes, nws yuav tsum noj rau kho, Yog hais tias lub roj teeb them teeb lit, los yog muaj tej yam lwm tsis ua hauj lwm nyob rau hauv lub generator.

Failures thiab lawv tshem tawm

Wb hais rau hauv lub tsheb yog ib tug voltmeter. Thiab nws qhia tau hais tias cov coupons qhov yog. Roj teeb uas them lub teeb kuj illuminates intermittently los yog tsis nyob rau hauv tag nrho tawm. Metering voltage ncaj qha mus rau roj teeb terminals qhia raws nraim 12 volts. Tab sis lub peev xwm yog ploj, tus oob khab tsis tig, thiab rau daim kab xev recorder nrog zog ua hauj lwm. Thawj kauj ruam yog huv si tag nrho cov tuab hlau, uas muaj them lub roj teeb. Siv voltage ntsuas ntawm davhlau ya nyob twg "30" ntawm lub generator. Yog hais tias nws yog ntau tshaj li uas nyob rau lub roj teeb, ntxuav lub davhlau ya nyob twg posts, los yog hloov lub hlau.

Yog hais tias nyob rau hauv lub twj paj nruag vaj huam sib luag voltmeter qhia tau hais tias lub xub ntiag ntawm xwb, tab sis lub teeb tsis muaj teeb, thiab lub roj teeb yog pom, nyob rau hauv kev phem ntawm lub qub system voltage, siv ib tug ob peb kauj ruam yooj yim. Tig rau lub siab tshaj plaws pes tsawg tus ntawm cov neeg siv, thiab saib yuav ua li cas coj nyob rau hauv ib tug voltmeter. Yog hais tias lub voltage tau poob sharply, siv lub stretch alternator siv. Nws pib npleem, vim hais tias nyob rau hauv thauj cov rotor emf tawm tsam cov stator. Thiab koj yuav tsum ua loj cov kev siv zog. Tsis tas li ntawd, nws yuav cia li hnav ib tug ntawm cov Pulleys. Ces, txawm lub installation ntawm ib tug tshiab siv yuav cawm tsis tau.

nrog kev puas tsuaj

Qhov saum toj no qhov teeb meem no tej zaum yuav tshwm sim nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm ntawm ib tug semiconductor diode. Yog hais tias muaj yog ib tug so nyob rau hauv lub stator winding yog tseem cai voltage nco nyob rau hauv load. Lauj lub generator thiab khiav diagnostics semiconductors. Lawv muaj ib tug ib tug-txoj kev conductivity. Rang lub stator winding mus ntes av txhaum. Nws yog ib nqi sau cia hais tias lub multimeter yuav nrhiav tau qhib, tiam sis qhov phem hu yog tsis zoo li. Rau lub hom phiaj no, zoo dua siv Megger.

Nws yuav tsum tau ntsuam xyuas thiab generator txhuam. Yog hais tias lub teeb uas them teeb illuminates lub roj teeb thaum uas tsis muaj kev ceev nrog lub teeb nyob rau hauv, nws kuj qhia hauv lub xub ntiag ntawm failures piav saum toj no. Los ntawm txhuam, ntau heev nyob. Yog hais tias lawv muaj ib tug ntev ntawm 5 hli los yog tsawg dua, koj yuav tau xyuam xim muab pov rau lawv tam sim ntawd. Yog hais tias lub roj teeb uas them lub teeb rau hauv hluav taws vim hais tias tsis ua hauj lwm ntawm lub txhuam, qhov teeb meem yog heev yooj yim mus nrhiav.

Ib txhia ntau breakdowns

Tiam sis ntau tshaj feem ntau tshaj li tsis nws yog hais tias nws yog tsis lit lub roj teeb uas them lub teeb, thiab muaj ib tug tsis ua hauj lwm. Ntxiv mus, nyob rau hauv cov ntaub ntawv ntawm burnout ntawm lub teeb nws tus kheej disappears lub voltage ntawm lub excitation winding. Qhia cov teeb meem no yog yooj yim - koj yuav tau mus xyuas lub filament ntawm lub teeb fixture. Tab sis feem ntau ntawm cov teeb yog blinking, yuav luv luv rau lub teeb li. Feem ntau yog vim li cas rau qhov no coj tus cwj pwm yog kev txawv txav hu nyob rau hauv ib cov saw tsav winding. Yuav kom tshem tawm huv tag nrho cov connectors, siv ib rab riam, ntwav txhuam ntoo, los yog thov ib tug tob tob lubricant xws li WD-40.
