I-VRLA Ibhetri ye-VRLA I-Fault Ibhetri ye-VRLA (Ibhetri ye-VRLA) Ukungaphumeleli kokuvuza, ngaphezu komonakalo womatshini obangelwa ukuthutha, ukuphatha, kubalulekile ngenxa yeziphene zokuvelisa, ezifana ne-injection ye-electrolyte egqithisileyo, ukutywinwa, ukutywinwa kwezinto ezingafanelekanga kunye nokutywinwa kwezinto eziguga, njl njl. Abanye abavelisi basetyenziswa kwi-oyile ye-silicone ejikeleze ibhetri ye-VRLA, esetyenziselwa ukuphucula ukusebenza kokutywinwa kwezindlu zebhetri zeVRLA. Kusenokubakho ulwelo olungeyo-asidi oluya kugobhoza lujikeleze ikholomu yepali ephakathi, okuqhelekileyo, hayi ulwelo oluvuzayo, nikela ingqalelo ukwahlula.

Ke ngoko, kufunyaniswe ukuba i-drain ye-VRLA ibhetri kufuneka itshintshwe ngokukhawuleza, okanye uyibuyisele ngaphambi kokuba ibhetri yeVRLA isondele kubomi. Kuya kwenzeka kwakhona xa isitywina sebhetri yeVRLA kunye nevalve yokhuseleko ingenangxaki. Iibhetri ezininzi ze-VRLA zikwi-exproprium, iibhetri ze-VRLA azinamjikelezo we-oxygen.

Itshaja ezintathu ezikwimo evulekileyo yebhetri yeVRLA ziyakhutshwa. Umlinganiselo we-asidi ye-sulfuric uphinde uphuculwe. Xa i-valve yokhuseleko igutyungelwe, i-electrolyte ayifuni, kwaye kukho i-asidi yamahhala.

Nokuba ii-absorber ze-asidi zasimahla, iibhetri zeVRLA zisengaphambili. I-electrolyte kwisahluli ingaphezulu. I-electrolyte engaphezulu kancinane kwi-electrolyte kwisahluli ichaphazela ukujikeleza kweoksijini, ukuze xa utshaja ibhetri entsha yeVRLA, isixa sombhobho sisikhulu ngokwentelekiso, iasidi yesulfuric ikhutshwe, yenze umsele.

Ibhetri ye-colloidal VRLA ikwimijikelezo ephezulu ye-50 ukuya kwi-100, ibhetri ye-VRLA ikwixesha lenguqu ye-liquid ecebileyo kwisisombululo esinqabileyo, ukukhupha kunamandla ngakumbi, kwaye i-gas ephumayo ivelisa i-colloid fine particles yenza i-acid acid. Ukuvuza kwebhetri yeVRLA kubalulekile ukuziphatha ekuvuzeni okubangelwa kukuvuza kwepali kunye nokutywinwa kwekhava yeqokobhe. Iindlela ezimbini zokutywina ze-VRLA i-shell shell shell ineendidi ezimbini: i-glue seal kunye nokutywinwa kobushushu.

Indlela ye-gelatin kukuba ikhava yegobolondo isetyenziswe njenge-epoxy resin seal, umgangatho wokutywinwa uchaphazeleka yi-epoxy resin glue, njengokuba kunokwenzeka ukuvuza kwe-epoxy resin ekugugeni kunye neengxaki zokuqhekeka. Itywina lobushushu lisemva kokufudumeza indlu ye-ABS kwiqondo lobushushu elithile (kunye nolwelo oluthile kunye nokuncamathela), lizalise kwisithuba esiphakathi kweqokobhe kunye nesigqubuthelo. Ukupholisa isigqubuthelo seqokobhe ngasemva sidityanisiwe, iqokobhe, icandelo elibophelelayo le-ABS yinto enye.

Ngoko ke, itywina lobushushu linokuthembeka kokutywinwa okuphezulu. Ukutywinwa kobushushu kunokusombulula ingxaki yokuvuza phakathi kwesigqubuthelo seqokobhe. Umgangatho wokutywina phakathi kweepali kunye neekepusi zeqokobhe yenye yezinto ezibalulekileyo ezichaphazela ubomi bebhetri yeVRLA.

Isakhiwo sokutywinwa kwekholamu ye-polar sineendidi ezi-4: Isakhiwo sokutywinwa kwe-resin 1; Isakhiwo sokutywinwa sesibini se-resin; Isakhiwo sokutywinwa kwe-3 yomatshini wokutywina; Isakhiwo sokutywinwa sekholamu ye-4HAGEN yelungelo lomenzi. I-VRLA I-Battery Leakage Phenomenon Uhlalutyo lobudlelwane phakathi kwe-1RLA yokuvuza kwebhetri kunye noyilo lwebhetri ye-electrolyte VRLA ngumgaqo osisiseko wokwamkela isisombululo esincinci, ukwenzela ukuba i-electrode ephilileyo ibonakala ifumene ukuxutywa okukhulu kwe-composite kwi-electrode engalunganga ngokujikeleza kwangaphakathi. Ukucinga ngokutsha kwegesi yangaphakathi yebhetri yeVRLA, igcina ibhalansi yamanzi kwi-electrolyte, ukwenzela ukuba ibhetri yeVRLA ivalwe.

Ukuba isixa se-electrolytic liquid sikhulu kakhulu, i-gas re-cooperator yangaphakathi ivaliwe, igesi yangaphakathi iyanda, uxinzelelo longezwa, kwaye kulula ukuvuza kwinxalenye ephosakeleyo ye-VRLA ibhetri. Ke ngoko, ubungakanani be-asidi yokongeza ibhetri yeVRLA ibhetri kufuneka ifaneleke. Ngokubhekiselele kwibhetri yeVRLA, ukuxinana kwe-electrolyte kulawulwa ngokubanzi ngu-1.

I-10, kunye ne-electrolyte density of discharge yi-1.30, kwaye ibhetri ye-VRLA ingabalwa ukubala ibhetri ye-VRLA nge-AH ubuncinane ubuncinane be-asidi. I-H2SO4 ecocekileyo efunekayo ngaphambi kokukhutshwa yile: w (H2SO4) = V×ye×M esulungekileyo H2O isixa: w (h2o) = v×D (1-M) I-H2SO4 ecocekileyo efunekayo emva kokukhutshwa yile: w (H2SO4) = V×ye×Ngalinye lamandla e-1AH akhululwa kwi-N-3.

36, kunye ne-H2SO4 ecocekileyo yi-3.66g, kwaye amanzi yi-0.67g.

Kwifomula, i-D yi-electrolyte density ekuqaleni kokukhutshwa, okuyi-1.30; m yipesenti yoxinaniso lobunzima bokuqala bokukhutshwa, okuyi-38%; ubunzima bepesenti yoxinzelelo emva kokukhutshwa, okuyi-16%; I-V yi-concentration D. Umthamo we-asidi ye-sulfuric.

Ngoko ke, ibhetri ye-VRLA kufuneka isetyenziswe kwisisombululo se-electrolytic nge-AH ukuze kuqinisekiswe ukuba i-electrolyte efunwayo kufuneka ibhengezwe ngokupheleleyo kwisahlulo, kwaye ezinye iipaseji zegesi ngokubanzi ziyi-17 g ye-glass fiber separator nge-AH. , I-asidi egcweleyo ye-asidi kwisahlulo se-G yi-0.8ml.

Ngoko ke, ubuninzi be-asidi yokufunxa yi-13.6 mL, iqinisekisa ukuba ulwahlulo lokutywina luninzi lwesixa se-asidi ukuya ngaphezu kwe-95%, ngokuqhelekileyo i-92%, oko kukuthi, ubuninzi be-asidi yi-12.5mL, kwaye isixa se-asidi kufuneka ilawulwe phakathi kwe-10.

9 ukuba 12.5ml. Indawo yokuvuza kwebhetri ye-2VRLA ibonwa ixesha elide, kwaye kufunyaniswe ukuba indawo yokuvuza kwebhetri yeVRLA ibalulekile kwitywina phakathi kwesigqubuthelo seqokobhe lebhetri yeVRLA (isigqubuthelo kunye netanki esezantsi zitywinwe okanye zibangelwa kukungqubana, ukutywinwa kweglue ukuqhekeka kubangela ukuvuza), ivalve yokhuseleko Decapulsate kunye nezinye iindawo zokuvuza kwe-otteric ukuvuza kunye nezinye iindawo ezivuzayo zolwelo oluvuzayo.

Izizathu zokuvuza kuzo zonke iindawo zihluke, kwaye amanyathelo ahambelanayo kufuneka athathwe emva kohlalutyo olubanzi. I-3VRLA iqokobhe lebhetri igubungele ukuvuza iqokobhe le-VRLA iqokobhe lebhetri iqokobhe itywina lisetyenziswa ngokubanzi njengeendlela ezi-2 zokuncamathelisa i-epoxy resin kunye netywina elishushu elidityanisiweyo, ngokwentelekiso, ifuthe elishushu lokutywina le-fuse lingcono, indlela kukwenza i-VRLA ibhetri yesigqubuthelo seplastiki ngokufudumeza (ABS) Okanye i-PP) eshushu inyibilika indibaniselwano ecinezelekileyo kunye. Ukuba ukushisa okutshisa okunyibilikayo kunye nexesha lilawulwa, licocekile kwaye lingenalo ukungcola, isitywina sithembekile.

Ibhetri yeVRLA ye-hot-fused seal liquid ibonwa, kwaye igesi iyatshisa, kwaye kukho umthunzi wobusi. Ayixinana kakhulu. Kuba kukho i-O2 kwindawo engaphakathi yebhetri yeVRLA, i-O2 ivuza ecaleni kwendlela yesanti ecaleni kwendlela yesanti.

ulwelo. I-epoxy resin adhesive itywinwe i-VRLA ibhetri evuzayo engamanzi, ngakumbi ukuxoka. Ukuba i-epoxy formula kunye nemeko yokuphilisa ilawulwa, inokutywinwa.

I-battercharge ye-VRLA ye-epoxy resin adhesive sealing liquid ifunyenwe ukuba i-sealant kunye ne-bonding yezindlu ziyi-interface bonding, amandla okubopha amkhulu, kulula ukuwa, kwaye kukho umngxuma we-lacemic okanye ukuqhekeka ekuvuzeni. Ekubeni i-epoxy resin ihlwempuzekile (ingakumbi ukunyanga kweqondo lokushisa eliphantsi), kulula ukubangela i-shell shell cover, kwaye kukho ibhetri ebalulekileyo ye-VRLA eyenzekayo kwi-cascade. Embindini, ngenxa yokusetyenziswa komxhuzulane, i-cascade deformation ibangela umaleko wokutywinwa kwebhetri yeVRLA, kwaye i-epoxy resin iqinile kwaye icrisp, phantsi kwamandla angaphandle, kulula ukubangela ukuqhekeka.
