I. Ukulahleka kwebhotri, i-original (1) iliso lombane elimnyama (iliso lombane likhawuleza xa ibhetri ishukunyiswa): ubunzima obuthile be-electrolyte abunelanga, kwaye ukukhutshwa okunzulu kubangelwa ukulahlekelwa kwebhetri (kwisixhobo sokulinganisa samanje, nako ayikwazi ukuvavanya iliso lombane. Ibhetri emnyama ayilungile, inokujongwa emva kokuzaliswa.

Umbane we-AC ubiza intlawulo eqhelekileyo yangoku kwiiyure ezingama-24 ukutyebisa iliso lombane (umntu umisela ukuba ibhetri yophukile. Ukuba ibhetri iphukile, ibhetri iyayeka ukusabela kweekhemikhali, kwaye ayikwazi ukuqhubeka ukuyikhupha kwiso lombane, ngoko ke esi siphakamiso asisungulwa). (2) Kukho iimeko ezimbini zamehlo aluhlaza: A.

I-voltage yesiphaluka evulekileyo nayo ingaphezulu kwe-12.5V, ukukhutshwa ngokukhawuleza kwe-10.5V okanye ngaphezulu, ibhetri ngokuqhelekileyo.

B, i-voltage yesiphaluka evulekileyo yi-10V, ukukhutshwa ngokukhawuleza kwe-8-0 kufuneka kube yi-battery-break (imiba yomgangatho wemveliso) (3) I-Electroplad emhlophe: Ukungaphumeleli kwenkqubo yokutshaja imoto kubangela ukuba i-voltage yokutshaja okanye yangoku inde kakhulu ukuba ibangele ilahleko ye-electrolyte yamanzi (ukongeza amanzi adibeneyo). Isikhumbuzo esikhethekileyo (1) Isiganeko esibuhlungu: ukutshaja kwexesha elifutshane (akukho luhlaza), ngokukhawuleza ulayishe isithuthi, kodwa isithuthi sinokuqalwa, kodwa ukujika akuvumelekanga ukuba sikwenze, i-original i-short-time charger ayiyongeza isiseko sebhetri (umxhuzulane okhethekileyo we-electrolyte awuhambisani nomgangatho), umbane ojikelezayo wombane, ngoko ke unika abantu ibhetri engayisitampu. (2) Ibhetri enzulu yokukhupha (iliso lombane elimnyama) ifakwe kwiminyaka emibini, eya kubangela ukutshatyalaliswa kwebhetri, kwaye isithuthi kufuneka sihlawulwe ngexesha, sibekwe ngamandla apheleleyo, kwaye sisuse uxhumano oluhle kunye nesithuthi.

Okwesibini, ukulahleka kwebhetri kuguqulwa, kwaye i-chemical reaction formula yokukhutshwa kunye nokutshaja kwebhetri yile ilandelayo: PBO2 + PB + 2H2S04→I-PBSO4 + 2H20 (ukukhutshwa) PBSO42H20→Kwimeko yokusetyenziswa okuqhelekileyo, i-PBO2 + PB + 2H2SO4 (ukutshaja) ibhetri isetyenziswa ngokuqhelekileyo, izinto ezisebenzayo (Pb02, kunye ne-Pb) zamacwecwe afanelekileyo kunye ne-negative (PB02, kunye ne-PB) ziguqulwa zibe yi-sulfate emincinci yeenkozo, ezi sulfate ezithambileyo ezincinci ezinjengokudla okuziinkozo ziyi-avareji. I-PBO2 kunye ne-PB ngexesha lokutshaja. Ukuba ukusetyenziswa kokugcinwa okungafanelekanga, i-particle encinci ye-crystalline sulfate ayinakuguqulwa ibe yinto esebenzayo ngexesha, ngokuthe ngcembe yenze i-crystalline particle thickness, eyenza i-plate vulcanization phenomenon, yinto yokuvelisa i-sulfate enzima emhlophe. I-Crystallization, ukutshaja kwakhona kunzima kakhulu ukuguqula ukukhokela kwezinto ezisebenzayo, ezi zikristale zesulfate ezirhabaxa kwaye zilukhuni zikhulu, ukungahambi kakuhle, kwaye ngaloo ndlela zithintela iipores zeplate esebenzayo, zithintele ukungena kunye nokusasazwa kwe-electrolyte, ukuchasana kwangaphakathi kwebhetri kongezwa, kwaye xa itshaja, ukukhokela kwe-sulfate kuncinci, kunye ne-P2 kunokwenzeka ukuba iguqulelwe kwi-P2. guqula.

Ukuba lide kakhulu, ezi sulfate zirhabaxa kwaye ziqinile ziya kuphulukana nokusebenzisa ukubuyisela umva. Ngenxa yoko, i-substance esebenzayo yeplate iyancitshiswa, umthamo wokukhupha uyancipha, kwaye ubomi benkonzo bufutshane kakhulu. Ilahleko yebhetri eneneni ibhekisa kwisenzeko sesenzeko kwi-lead-on-the-electrode ye-electrode ayikwazi ukuguqula izinto ezisebenzayo.

Ibhetri i-sulfuricated emva kwe-sulfuric acid ye-sulfuric, kukho izinto ezimbalwa: (1) Ibhetri iphakame ngokukhawuleza ngexesha lenkqubo yokutshaja, ixesha layo lokuqala kunye ne-voltage yokugqibela iphezulu kakhulu, umbane wokugqibela wokutshaja unokufikelela kwi-2.90V / enye. (2) Ngethuba lenkqubo yokukhupha, i-voltage iyancipha, oko kukuthi, ukuwa kwangaphambi kwexesha kwi-voltage yokuphelisa, umthamo uyancipha kakhulu ngamanye amabhetri.

(3) Xa utshaja, ubushushu be-electrolyte bunyuka ngokukhawuleza, kulula ukugqitha kuma-45 ¡ã C. (4) Xa utshaja, ubuninzi be-electrolyte bungaphantsi kwesiqhelo, kwaye amaqamza omoya aphambi kwexesha xa utshaja. (5) Xa ibhetri ikwindalo, umbala kunye nemo yepleyiti inokufunyanwa ingaqhelekanga.

I-electrode plate ene-positive inombala obomvu (oqhelekileyo omnyama omnyama), umphezulu weplate ye-polar unendawo emhlophe ye-sulfate, i-negative plate ibuhlungu, kwaye umphezulu unzima, kwaye umnxeba ufana nokuvakalelwa kwesanti, kwaye i-plate inzima. (6) Ityuwa enkulu ye-sulfuric acid, i-crystals ekhokelayo-emhlophe eyenziwe yiplate eyenziwe, kwaye ngokubanzi, into esebenzayo ayinakubuyiselwa. Okwesithathu, isigwebo sesiqhelo sokulahleka kwebhetri ye-1, umbane wokuvula ibhetri ungaphantsi kwe-12.

I-3V, ilahleko yelahleko ihlukaniswe ngokubanzi ibe: a) ilahleko encinci: i-voltage yesiphaluka evulekileyo yi-11.7V ~ 12.3V.

b) Ilahleko ephakathi: amandla ombane wesekethe evulekileyo yi-10V ~ 11.7V. (I-Vulcanization eNcinci) C) Ilahleko Emandundu: Umbane ovulekileyo wesekethe ungaphantsi kwe-10V.

(I-vulcanization ephakathi kunye nobunzima) 2, umboniso wesimo sebhetri umthamo (i-electro-iso) eboniswe kumhlophe. Okwesine, indlela yombane eyongezelelweyo kunye neemfuno zisekelwe kwindlela yokukhupha umatshini wokutshaja kunye nokulahleka kwebhetri kwezi ndlela zintathu zokutshaja: 1, ukutshaja uxinzelelo rhoqo: ngoxinzelelo oluqhubekayo 16V6-QW-68An umda webhetri 17A6- QW-90N umda webhetri 22A intlawulo 4 ~ 12 iiyure. Ixesha lokutshaja ngokuxhomekeke kwiqondo lokuphulukana nomthamo webhetri.

Le ndlela yokutshaja ifanelekile ilahleko encinci yebhetri. I-2, isiteji sokutshaja ngokuqhubekayo: Icandelo le-1: I-6-QW-68 ibhetri ihlawuliswa kwinqanaba elilandelayo emva kokuba i-voltage ihlawuliswe kwi-voltage ukuya kwi-14.4V ngokuqhubekayo ngoku i-7A.

Ibhetri ye-6-QW-90 ihlawuliswa kwi-voltage emva kokuba i-voltage ihlawuliswe kwi-voltage ukuya kwi-14.4V. Icandelo 2: I-6-QW-68 ibhetri ibiza i-6 kwiiyure ze-20 kunye ne-3 eqhubekayo yangoku.

5a. I-6-QW-90 intlawulo yebhetri ye-6 kwiiyure ze-20 kunye ne-4.5a eqhubekayo yangoku.

Elona xesha lokutshaja lixhomekeke kubungakanani belahleko yebhetri. Le ndlela yokutshaja ifanelekile kwiibhetri ezilahlekileyo eziphakathi. I-3, i-6-QW-68 itshaja ibhetri eqhubekayo ngoku i-6-QW-68 iiyure ezingama-40 kunye ne-3A yangoku.

I-6-QW-90 ibhetri ibiza i-20 kwiiyure ze-40 kunye ne-4A yangoku rhoqo. Ixesha elililo lokutshaja lixhomekeke kwiqondo lokuphulukana nomthamo. Le ndlela yokutshaja ifanelekile kwiibhetri ezinganyangekiyo.

4. I-5, isigwebo sokuphela kokutshaja 1) I-voltage yebhetri inkulu kune-16V kwaye izinzile kwiiyure ze-3 ngaphandle kokutshintsha. 2) Ukuboniswa kwamandla ebhetri (iliso lombane) elibonisa uhlaza alutshintshi.

3) Xa kuyimfuneko, jikeleza i-electropament, ulinganise ubuninzi be-electrolyte nge-1.28 g / cm3 okanye ngaphezulu kwaye uzinzile ungatshintshi kunye ne-densitometer. Ukuba iingongoma ezi-3 ezingentla, isitatimende sigqityiwe, kwaye ibhetri yokutshaja imisiwe ukubuyisela ukusetyenziswa okuqhelekileyo.
