Yintoni i-Desulfation Mode?
Imowudi ye-desulfate luphawu olukhethekileyo kwiitshaja zebhetri esusa i-lead sulfate crystal buildup kwiipleyiti zeebhetri{0}}zeasidi. Xa ibhetri -yeasidi ihlala ixesha elide, ezi kristale ziyaqina kwiipleyiti zebhetri kwaye zithintele ibhetri ekwamkeleni okanye ekubambeni intlawulo. Imo ye-Desulfation isebenza ngokulawulwayo okuphezulu{4}}ii-voltage pulses ukophula ezi kristale kunye nokubuyisela amandla ebhetri ekusebenzeni.
Yintoni ebangela iBattery Sulfation
I-Sulfation yenzeka ngokwesiqhelo kwimichiza ephakathi kweebhetri zelothe{0}. Xa ukhupha ilothe -ibhetri yeasidi, i-electrolyte (iasidi yesulfuric kunye namanzi) idibana neepleyiti zelothe ukuze ivelise ilothe yesulfate kwaye ikhuphe amandla ombane. Ngexesha lokutshaja kwakhona, le nkqubo kufuneka iguqulwe, iguqule i-lead sulfate ibuyele kwizinto ezisebenzayo.
Ingxaki iqala xa iibhetri zihlala zingaphelelanga okanye zikhutshwe ngokupheleleyo. Iikristale ezincinci zesulfate ezikhokelela ngexesha lokusetyenziswa okuqhelekileyo ziqala ukukhula zibe zikhulu kwaye zibe lukhuni. Ezi kristale zilukhuni zixhathisa inkqubo yokutshaja kwaye zinamathele kwiipleyiti zebhetri ngokusisigxina. Ngokuhamba kwexesha, le buildup inciphisa umthamo kunye nokusebenza kwebhetri.
Iimeko ezininzi zikhawuleza i-sulfate:
Ukugcinwa ngaphandle kwentlawuloidala eyona sulfation imbi. Ibhetri eshiywe ihleli iiveki okanye iinyanga, nokuba iqale igcwaliswe ngokupheleleyo, iyakuzikhupha ngokwayo{1} kwaye iphuhlise iikristale zesulfate. Xa ihleli ixesha elide, kokukhona ezi kristale ziba nzima.
Ukutshaja ngaphantsiikhusela ibhetri ekuguquleni ngokupheleleyo i-lead sulfate ibuyele kwizinto ezisebenzayo. Umjikelo ngamnye wentlawulo engaphelelanga ushiya i-sulfate engaphezulu kwiiplate.
Ukukhutshwa okunzuluoko kuwisa amandla ombane ebhetri angaphantsi kwe-10.5V abangela i-sulfation ekhawulezileyo. Ukungalingani kweekhemikhali okugqithisileyo kuvelisa iikristale ezinkulu ezakha ngokukhawuleza.
Amaqondo obushushu aphezulungaphezulu kwe 75℃F kabini izinga le sulfation kwi 10 -kunyuso ngalunye lwesidanga. Ubushushu bukhawulezisa zombini ukuzikhupha kunye nokwakheka kwekristale.
Xa i-sulfation ifikelela kumanqanaba aphezulu, ibhetri ibonisa iimpawu ezicacileyo. Amandla e-cranking ehla ngokubonakalayo. Ukutshaja kuthatha ixesha elide kunesiqhelo. Ibhetri inokuvakala ishushu ngexesha lokutshaja. I-voltage yehla ngokukhawuleza phantsi komthwalo. Kwiimeko ezinzima, ukufundwa kwe-voltmeter kwibhetri "egcwele ngokupheleleyo" kubonisa kuphela i-12.0-12.2V endaweni ye-12.6-12.8V enempilo.
Indlela iDesulfation Mode isebenza ngayo
Imowudi ye-desulfate isebenzisa ubuchule bokulungisa i-pulse ukwahlula iikristale zesulfate. Itshaja inika amandla ombane aphezulu-amandla ombane aphezulu - ngokwesiqhelo yi-15-20V yebhetri eyi-12V - kumaza amaninzi kodwa ubushushu obuphantsi. Ezi pulses zidala ukungcangcazela kwinqanaba lemolekyuli eqhekeza i-crystalline structure.
Inkqubo ihluke kakhulu kwintlawulo eqhelekileyo. Ukutshaja okusemgangathweni kusebenzisa amandla ombane azinzileyo malunga ne-14.4V ukutyhala amandla ebhetri. I-Desulfation pulses inyuka iye kwi-15-20V okomzuzwana, emva koko ihlehle. Esi senzo sokubetha sijolise ngokukodwa kwiikristale zesulfate enzima ngaphandle kokutshisa ibhetri.
Iitshaja ezahlukeneyo zisebenzisa i-desulfation ngeendlela ezahlukeneyo:
Iinkqubo ze-desulfation ezizenzekelayoFumana iibhetri ezifakwe i-sulfate ngokuvavanya amandla azo okwamkela intlawulo kumbane oqhelekileyo. Xa itshaja isebenzisa i-14V kunye nezivamvo phantse akukho flow yangoku, ibona ukuchasana okuphezulu kwangaphakathi kwi-sulfation. Itshaja ke iyazitshintshela kwimo yedesulfation. Nje ukuba ibhetri iqalise ukwamkela intlawulo ngokwesiqhelo, isixokelelwano sitshintshela kwizigaba zokutshaja eziqhelekileyo.
Iindlela ze-desulfation yezandlaifuna ukuba ukhethe useto. Ezi zihlala ziqhuba ixesha elimiselweyo - ngokuqhelekileyo iiyure ezingama-24 kwiitshaja zeBlack+Decker, okanye ukuya kutsho kwiiyure ezi-2 kwiimodeli zeBattery Sitter. Itshaja isebenzisa iipulse ngalo lonke eli xesha, emva koko ivavanye ukuba ibhetri ibuyele ngokwaneleyo na.
Iinkqubo eziqhubekayo zokugcinwa kwe-pulseukusuka kwiinkampani ezifana nePulseTech faka iqondo eliphantsi{0}}i-desulfation pulses rhoqo ngelixa ibhetri itshaja nangexesha logcino. Le ndlela ithintela ukwakhiwa kwe-sulfation kunokuba iphathwe emva kwenyani.
Eyona ndlela ilungileyo ye-pulse waveform ibaluleke kakhulu. I-desulfate esebenzayo ifuna ulawulo oluchanekileyo lwexesha lokunyuka kwe-pulse, ububanzi, i-frequency, kunye ne-amplitude.
