Kev faib tawm yooj yim

1. Alternator voltage regulator tuaj yeem muab faib ua: raws li txoj cai ua haujlwm:
(1) Tiv tauj voltage regulator
Kev sib cuag voltage regulator yog siv ua ntej, qhov no regulator hu vibration zaus qeeb, muaj mechanical inertia thiab electromagnetic inertia, low voltage regulator raug, contact easy to produce sparks, large radio interference, poor reliability, short life, has been eliminated.
(2) Transistor regulator
Nrog rau txoj kev loj hlob ntawm semiconductor technology, transistor regulators tau txais yuav.Nws qhov zoo yog: lub transistor hloov zaus yog siab, thiab tsis tsim sparks, siab hloov raug, tab sis kuj muaj qhov zoo ntawm lub teeb yuag, me me, lub neej ntev, kev ntseeg siab, me me hauv xov tooj cua cuam tshuam, thiab lwm yam, thiab tam sim no dav dav. siv hauv Dongfeng, Jiefang thiab ntau yam ntawm cov qauv qis kawg.
3) Integrated Circuit Court regulator
Ntxiv nrog rau qhov zoo ntawm transistor regulators, integrated circuit regulators kuj yog ultra-me, mounted hauv lub tshuab hluav taws xob (tseem hu ua built-in regulators), txo cov xaim sab nraud, thiab cov cua txias tau txhim kho, thiab tam sim no tau siv dav hauv Santana.Audi thiab lwm yam sedan qauv.
(4) Computer-tswj regulator
Tom qab ntsuas tag nrho cov khoom thauj ntawm lub cev los ntawm lub tshuab hluav taws xob thauj khoom, lub teeb liab raug xa mus rau lub tshuab hluav taws xob lub tshuab hluav taws xob, thiab tom qab ntawd lub tshuab hluav taws xob hluav taws xob hluav taws xob yog tswj los ntawm lub tshuab computer, thiab lub tshuab hluav taws xob sib nqus tau qhib thiab tawm raws sijhawm. , uas yog, kev ua haujlwm ib txwm muaj ntawm lub tshuab hluav taws xob tuaj yeem lav tau zoo, lub roj teeb tuaj yeem raug them kom txaus, thiab lub cav thauj khoom tuaj yeem txo qis thiab roj kev lag luam tuaj yeem txhim kho.Piv txwv li, Shanghai Buick, Guangzhou Honda thiab lwm lub tshuab hluav taws xob siv lub tshuab hluav taws xob no.

2. Voltage regulator
Raws li qhov sib txuam alternator hlau hom tuaj yeem muab faib ua:
(1) Sab hauv hlau hom regulator
Lub voltage regulator haum rau txuam nrog lub internal khi-type alternator yog hu ua Internal khi-type regulator;
(2) Sab nrauv hlau hom regulator
Tus tswj hluav taws xob tsim nyog rau kev sib txuam nrog lwm yam khi-hom alternator yog hu ua sab nraud khi-hlau regulator.

Nyob rau hauv cov txheej txheem ntawm kev siv, rau lub transistor regulator, nws yog qhov zoo tshaj plaws los siv cov regulator teev nyob rau hauv lub tsheb phau ntawv, yog hais tias lwm yam qauv siv los hloov, ntxiv rau lub nominal voltage thiab lwm yam kev txwv tsis pub thiab tus thawj regulator yog tib yam, Lub tshuab hluav taws xob hloov pauv yuav tsum yog tib yam li tus thawj tswj hwm daim ntawv hlau, txwv tsis pub, lub tshuab hluav taws xob yuav tsis ua haujlwm zoo vim yog lub zog hluav taws xob.Rau kev sib xyaw ua ke ntawm cov tswj hluav taws xob, lawv yuav tsum mob siab rau thiab tsis tuaj yeem hloov pauv.

Siv kev saib xyuas

Tus neeg tswj hwm feem ntau tsis tso cai rau kev tshem tawm lub hau thaum siv, thiab qhov xwm txheej ib txwm yog ua kom tiav kev tshuaj xyuas thiab tu txhua txhua 200h lossis yog li ntawd, thiab nws cov ntsiab lus yog raws li hauv qab no:

1. Tshem tawm cov ntaub ntawv thiab tshuaj xyuas qhov chaw tiv tauj rau cov av thiab hlawv puas.Yog tias muaj av, so qhov chaw tiv tauj nrog ib daim ntawv huv.Yog hais tias qhov kev sib cuag yog ablated los yog tsis sib xws thiab kev sib cuag tsis zoo, nws yog feem ntau smoothed nrog "00" sandpaper los yog xuab zeb strip, thiab thaum kawg wiped nrog huv daim ntawv.

2.Kuaj xyuas qhov ruaj khov ntawm txhua qhov txuas, ntsuas qhov tsis kam thiab tus nqi tsis kam ntawm txhua lub kauj.Yog tias muaj kev puas tsuaj, nws yuav tsum tau kho lossis hloov nrog lub sijhawm tshiab.

3.Kuaj xyuas qhov kaw qhov hluav taws xob thiab rov qab tam sim no ntawm lub ntsuas hluav taws xob tam sim no, qhov txwv qhov hluav taws xob ntawm qhov hluav taws xob hluav taws xob, qhov txwv tam sim no ntawm qhov txwv tam sim no ntawm lub nres tam sim no, thiab qhov khoob thiab cov pa tawm ntawm ntau qhov sib cuag.Yog tias nws tsis ua raws li qhov yuav tsum tau ua, nws yuav tsum tau kho.

4.Kuaj xyuas lub regulator kho thiab xyuam xim rau qhov qhia ntawm lub charger ammeter pointer thaum pib lub cav diesel.Yog tias rab koob ntawm ammeter tseem taw tes rau sab "-" thaum lub cav diesel khiav ntawm qhov nruab nrab ceev lossis siab dua, qhov no txhais tau hais tias kev sib cuag ntawm lub tshuab hluav taws xob tam sim no tsis raug txiav, thiab qhov hloov hauv av yuav tsum tau txiav tawm sai sai;Txwv tsis pub, nws yuav ua rau lub roj teeb, regulator, charging generator, thiab lwm yam. Yog hais tias lub koob ntawm ammeter tseem taw tes rau "0" tom qab lub cav diesel pib mus rau qhov ntsuas ceev, qhov kev hloov kho ntawm cov lus piav qhia tsis raug kho raws li cov kev xav tau. , thiab nws yuav tsum tau rov kuaj xyuas thiab kho.
