Hais txog Lub Hwj Chim Lub Hwj Chim Lub Hwj Chim Kev Pom Zoo
Sep 03, 2018| 1. Muaj suab nrov txawv txav thaum lub sijhawm ua haujlwm, qhov taw qhia lub zog thiab qhov taw qhia kev them nyiaj yog qhov tsaus thiab flashing
Qhov laj thawj ntawm kev ua haujlwm tsis zoo yog tias IC1 puas lawm. Ceev faj thaum hloov nws. Tsis txhob ua rau cov ntawv ci tooj liab ntawm cov ntawv luam tawm. Tom qab kev hloov pauv yog qhov qub, kho R28 kom cov zis hluav taws xob ntawm lub charger nyob rau hauv qhov kev ua haujlwm ib txwm muaj.
2. Muaj lub suab txawv txav thaum ua haujlwm, thiab tsis muaj nqi.
Xyuas seb puas muaj ib qho kev sib txuas lossis kev puas tsuaj ntawm C8 ntawm lub rooj tsavxwm. Feem ntau, hloov C8 tuaj yeem daws nws.
3. Thaum tshav kub kub thiab suab nrov txawv txav
Qhov ua rau qhov txhaum yog tshwm sim los ntawm kev puas tsuaj rau cov zis theem damping kuj R31 thiab C17. Tsis tas li ntawd, C12 qhib Circuit Court lossis virtual soldering kuj tuaj yeem ua rau cov teeb meem saum toj no.
4. Ua npaws hnyav, txawm tias kub kub deformation ntawm lub plhaub sab nraud
Qhov no feem ntau yog tshwm sim los ntawm kev ua tsis tiav ntawm qee cov neeg siv los nqa qee yam khoom thiab xoob qhov chaw. Qhov kev ua haujlwm tseem ceeb yog raws li hauv qab no: Thaum C18 looses lub vuam virtual, nws yuav ua rau lub xeev ua haujlwm ntawm V1 thiab V2 tsis zoo. Lub tshav kub loj heev. Thaum cov ntaub ntawv roj teeb yog deformed hnyav, lub rooj tsav xwm hluav taws xob tau hlawv, ua rau V1 thiab V2 puas. C18 tuaj yeem rov welded thiab kuaj xyuas. V1, V2, R4, R7. Yog tias qhov txhaum tsis tuaj yeem tshem tawm, xyuas seb puas muaj qhov qhib Circuit Court hauv D15 thiab D21. Tsis tas li ntawd, qee cov tuam ntxhab siv ob lub diode rau cov zis rectifier. Ib qho kev qhib Circuit Court kuj ua rau muaj qhov txhaum saum toj no. Qee zaum qhov txhaum yuav ua rau V1 thiab V2. Ib qho puas lawm. Xyuas thiab hloov tib lub sijhawm.
