Kutheni ibhetri yeVRLA iza kulahleka ngamanzi?

Ukulahleka kwamanzi yeyona nto iphambili ebangela ibhetri ye-vrlaukwehla komthamo, inxulumene nolwakhiwo lwayo olubi lwe-electrolyte. Ukulahleka kwamanzi kwebhetri sesona sizathu siphambili sokuchaphazela ubomi bebhetri, ukulahleka kwamanzi amaninzi kuya kukhokelela ekunciphiseni ulwelo lwebhetri kunye nokwehla kwamandla ebhetri.

Ibhetri engenasondlo isebenza kwimeko embi yolwelo lwe-electrolyte, i-electrolyte yayo igcinwa ngokupheleleyo kwii-separators. Nje ukuba ilahleko yamanzi, amandla ebhetri aya kuncipha, xa ilahleko yamanzi ifikelela kwi-25%, ubomi bebhetri buya kuphela. Kakade ke, ngenxa ye-voltage ephezulu kakhulu yokutshaja, i-electrolyte reaction iyanda, isantya sokukhululwa kwegesi siya siphezulu, ilahleko yamanzi iya kwenzeka ngokuqinisekileyo. Kwaye nokuba iqondo lobushushu bomsebenzi webhetri liyanyuka, kodwa i-voltage yokutshaja ayilungiswanga, kuya kwenzeka ilahleko yamanzi, nayo.

Eyona nto iphambili ebangela ukuba amandla ebhetri anciphe kukulahlekelwa ngamanzi. Xa ibhetri ilahlekelwe ngamanzi, iipleyiti zebhetri ezibonisa ukuba ibhetri ilahlekile/ingasebenzi kakuhle aziyi kuyichukumisa i-separator kwaye i-electrolyte ayanelanga ukuba isebenze, ngoko ke ibhetri ayinawo umbane. Nangona ibhetri yokugcina isebenzisa ubuchwepheshe bokujikeleza ioksijini, iya kunciphisa ukulahleka kwamanzi kwe-electrolyte,nangona kunjalo, ukulahleka kwamanzi okubangelwa sisizathu esingezantsi akunakuphetshwa ngexesha lokusetyenziswa:

1. Ukuba iseti yevolthi edadayo ifanelekile kwibhetri yangoku (njengoko umzi-mveliso owahlukileyo unesicelo esahlukileyo), kuya kubakho impembelelo enkulu kubomi bebhetri.Xa i-voltage edadayo iphezulu kancinci okanye ubushushu bebhetri bunyuka, kufuneka i-voltage edadayo incitshiswe ngoko nangoko, kungenjalo i-voltage edadayo yebhetri iphezulu kakhulu, ngoko ke umsinga wokutshaja ongaphezulu uya kwanda, ngoko ukusebenza kwe-oxygen recombination reaction kuya kuncipha, ekugqibeleni kuya kwenzeka ukulahleka kwamanzi, kwaye kukhawulezise inkqubela yokulahleka kwamanzi ebhetri.

2. Ukusetyenziswa rhoqo kakhulu kuya kukhawulezisa ukugqwala kwegridi yeepleyiti ze-lead ezilungileyo,Isiphumo segridi yeepleyiti ze-lead ezilungileyo kukuba i-lead kwigridi yeepleyiti ze-lead iya kutshintsha ibe yi-lead dioxide, i-oksijini eceliweyo iya kuvela emanzini akwi-electrolyte kuphela, ngoko ke iya kusebenzisa amanzi amaninzi. Ngamanye amaxesha, ngenxa yempazamo yevalvu yomoya, i-hydrogen eninzi kunye ne-oksijini ziya kukhupha ibhetri, zikhokelele ekulahlekeni kwamanzi.

3. Ibhetri emva kokulahleka kwamanzi kuthetha ukuba inyuse uxinzelelo lwe-sulfuric acid.Ngenxa yokuba olu xinzelelo luyanda, i-sulfation iya kuba nzima kakhulu, kwaye yehlise amandla omjikelo we-oxygen yeepleyiti ze-lead ezilungileyo. Ngoko ke i-sulfation yebhetri iya kuba nzima ukulahleka kwamanzi, kwaye ukulahleka kwamanzi kuya kuba nzima i-sulfation ngasemva.

Okungasentla akupheleli nje ekubetheni kwethuii, kodwa kuzo zonke iibhetri ze-agm nezejeli zaseTshayina, ziya kuyiphepha ingxaki kwaye ziphucule ukusebenza kwebhetri.

Nceda ngokufanelekileyo apha ngasentlaukuphepha iingxaki.
