Yuav ua li cas kom them lub tsheb roj teeb kom raug tom qab nws khiav tawm lub zog kom tsis txhob muaj kev puas tsuaj?

Thaum lub roj teeb lub tsheb khiav tawm, them nws kom raug yog qhov tseem ceeb los tiv thaiv lub roj teeb puas thiab ua rau lub neej ntev. Thaum them nyiaj, yuav tsum tau them nyiaj rau txoj kev them nqi, kev tswj tam sim no, ib puag ncig thiab cov ntsiab lus ua haujlwm. Cov kauj ruam tshwj xeeb thiab lus ceeb toom yog raws li hauv qab no:
I. Ua ntej- Kev Npaj them nqi: Paub meej tias lub roj teeb muaj xwm txheej thiab ib puag ncig nyab xeeb
Xyuas hom roj teeb
Tshawb xyuas seb lub roj teeb puas yog cov qauv txhuas-acid roj teeb (yuav tsum tau saib xyuas tsis tu ncua) lossis kev saib xyuas- roj teeb dawb (tsim kaw, tsis tas yuav tsum muaj dej).
Kev tu- roj teeb dawb yuav tsum tsis muaj kev ua haujlwm ntxiv thaum them nyiaj. Txawm li cas los xij, rau cov qauv txhuas -acid roj teeb, xyuas cov qib electrolyte (electrolyte theem yuav tsum npog daim hlau 10-15mm). Yog tias cov dej qis dhau lawm, ntxiv cov dej distilled (tsis txhob siv cov dej kais dej lossis dej ntxhia vim tias cov dej tsis huv tuaj yeem ua kom cov phaj corrosion).
Xaiv qhov chaw nyab xeeb
Kev them nyiaj yuav tsum tau ua nyob rau hauv lub qhov dej - qhov cua qhov chaw nyob deb ntawm qhov hluav taws kub (cov hmoov lead- cov roj teeb kua qaub yuav tso cov roj hydrogen thaum lub sij hawm them thiab tawg ntawm kev sib cuag nrog hluav taws qhib).
Tsis txhob them rau qhov kub siab (piv txwv li, tshav ntuj ncaj qha) lossis qis qis (qis dua 0 degrees Celsius). Qhov kub thiab txias tuaj yeem cuam tshuam rau kev them nqi thiab kev puas tsuaj rau cov roj teeb.
Disconnect roj teeb (yeem)
Yog tias lub tsheb hloov pauv tau siv rau kev them nyiaj (piv txwv li luv luv), xyuas kom meej tias tus ncej tsis zoo (dub cable) raug txiav tom qab lub tsheb raug kaw los tiv thaiv luv luv - Circuit Court lossis kev puas tsuaj rau lub tsheb hluav taws xob hauv lub sijhawm them nyiaj.
Yog tias siv lub charger sab nraud, nws raug nquahu kom txiav lub roj teeb ntawm lub tsheb (thawj tus ncej tsis zoo, tom qab ntawd tus ncej zoo) los tiv thaiv lub charger tam sim no los ntawm kev thim rov qab thiab kom tsis txhob muaj kev puas tsuaj rau lub tsheb hluav taws xob.
ii. Xaiv cov khoom siv them nyiaj zoo
Preference rau ntse chargers
Smart chargers cia li ntes lub roj teeb voltage thiab muaj peev xwm, kho tam sim no them (xws li tam sim no, tas li siab, ob-theem them), thiab tsis txhob overcharging los yog overcharging.
Cov khoom siv hluav taws xob zoo ib yam (xws li, cov khoom siv hluav taws xob tas li, xav tau kev teeb tsa tam sim no. Ntau dhau tam sim no (ntau tshaj 1/10 ntawm lub roj teeb muaj peev xwm) ua rau cov phaj sulfation, ua rau cov roj teeb muaj peev xwm txo qis; tam sim no tsis txaus tuaj yeem ua rau lub sijhawm them ntev.
Sib piv them voltage;
12V automotive roj teeb feem ntau muaj qhov them hluav taws xob ntawm 13.8-14.4V (float charging theem). Lub charger ntau dhau (piv txwv li, dhau 15V) ua kom cov electrolyte decomposition, ua kom muaj roj ntau uas tuaj yeem ua rau lub roj teeb nthuav dav thiab txawm tawg.
Lub roj teeb 6V yuav tsum muaj lub charger nrog qhov tsim nyog voltage kom tsis txhob siv tsis raug.
III. Cov txheej txheem them nqi: Tswj tam sim no thiab lub sijhawm
Cov theem thaum ntxov: qis pib tam sim no
Cov roj teeb uas muaj qhov paug tawm hnyav (qhov hluav taws xob tsawg dua 10V) yuav tsum tau them tsis pub dhau 1-2 teev nrog cov tam sim no me me (piv txwv li, 2-3A) txhawm rau qhib cov khoom siv hluav taws xob ntawm lub vaj huam sib luag thiab tiv thaiv lub vaj huam sib luag los ntawm kev khoov lossis los ntawm kev tawg vim muaj qhov hluav taws xob tam sim no.
Piv txwv li, thawj zaug nqi tam sim no ntawm aa 60Ah roj teeb tuaj yeem raug teeb tsa rau 3A (60Ah ÷=10=6A, tab sis nws pom zoo kom them tus nqi ib nrab thaum muaj qhov paug tawm loj).
Them Nyiaj Them Tseem Ceeb: regulating tam sim no.
Thaum lub roj teeb voltage tshaj 12V, tam sim no maj mam nce mus rau 1/10 ntawm lub roj teeb lub peev xwm (piv txwv li, 60Ah roj teeb yog 6A).
Thaum them nyiaj, xyuas lub roj teeb kub tsis tu ncua (kov lub casing; nres them yog tias koj hnov ​​kub heev). Yog tias qhov kub siab tshaj 50 degrees Celsius, nres them thiab cia lub roj teeb txias.
Termination: Tsis txhob overcharge
Kev them nyiaj yuav tsum nres tam sim yog tias qhov tam sim no tsawg dua 0.5A lossis yog tias lub charger qhia tias "tag nrho."
Overcharging ua rau dej hauv electrolytes tawg, ua rau oxygen thiab hydrogen gas. Qhov no ua rau lub zog sab hauv ntawm lub roj teeb, uas tuaj yeem ua rau lub casing tawg lossis tawg.
IV. INTRODUCTION Post-Kev Them Nqi: Rov siv dua thiab kho
** Teem thiab sim** Tom qab them nyiaj, tso lub roj teeb rau 1-2 teev kom ruaj khov rau cov khoom siv tshuaj. Qhov voltage yog ntsuas los ntawm ib tug multimeter:
Qhov voltage ntawm A tag nrho them 12V roj teeb yuav tsum yog 12.6-12.8V (static voltage).
Yog tias qhov hluav taws xob qis dua 12.4V, nws qhia tias tsis muaj kev them nyiaj lossis roj teeb aging uas yuav tsum tau them rov qab lossis hloov roj teeb.
Rov txuas cov roj teeb
Yog tias lub roj teeb raug txiav ua ntej, txuas rau pem hauv ntej davhlau ya nyob twg (liab cable) thiab tom qab ntawd txuas lub davhlau ya nyob twg tsis zoo (dub cable) thaum lub sijhawm teeb tsa kom tsis txhob muaj luv luv.
Tom qab pib lub tsheb, tawm lub cav tsis ua haujlwm rau 10-15 feeb kom them lub roj teeb los ntawm lub tshuab hloov pauv (tshwj xeeb yog tias lub roj teeb qis tom qab tsav luv).
Cov lus qhia txog kev tu txhua hnub
Tsis txhob nres ntev (pib lub tsheb tsawg kawg ib zaug hauv ib lub lis piam tsawg kawg 20 feeb) txhawm rau tiv thaiv roj teeb tus kheej - paug.
Ntxuav cov roj teeb tsis tu ncua (so nrog cov ntaub ntub dej kom tsis txhob muaj kua qaub) thiab xyuas cov terminals xoob lossis oxidized (oxidation tuaj yeem kho nrog dej kub lossis ib tus neeg saib xyuas tshwj xeeb).
Yog tias koj tsis siv lub tsheb ntev, txiav lub roj teeb tsis zoo los yog siv lub tshuab hluav taws xob tshwj xeeb kom them nyiaj ntxiv (piv txwv li hauv "floating charging" hom).
V. Kev tuav cov rooj plaub tshwj xeeb
* Cov roj teeb hnyav heev (voltage tsawg dua 9V): qhov no yuav qhia tau tias muaj sulfation sib sib zog nqus, uas nyuaj rau rov qab los tom qab them nyiaj ib txwm. Sim "pulse repair charging" (uas yuav tsum muaj cov cuab yeej tshwj xeeb) lossis tsuas yog hloov lub roj teeb.
Bulgarian roj teeb los yog cov roj teeb xau: tam sim ntawd nres siv cov roj teeb thiab hloov lawv nrog cov tshiab. Lub roj teeb muaj kev nyab xeeb; txuas ntxiv them nws tuaj yeem ua rau tawg.
Nrog cov txheej txheem them nyiaj kom zoo thiab kev saib xyuas niaj hnub, roj teeb puas tuaj yeem zam tau zoo, txuas ntxiv roj teeb lub neej mus rau 3-5 xyoo (ib txwm siv). Yog hais tias lub roj teeb feem ntau depleted, xyuas lub tsheb kom tsis txhob xau (yog tias lub tshuab hluav taws xob tsis hloov) lossis yog lub tshuab hluav taws xob AC them tsis zoo.
