Maintenanceoflead-acid batteries, the firstgeneral understanding ofthe structure andprinciples oflead-acid batteryisvery necessary.Sealed lead-acidbatteriesby thepositive and negative plates,a separatorand an electrolyte,the battery slotandtie bars(or leadparts), terminalsand the exhaust valveand other components.
First, the maincomponentsof the battery
1,is the core componentof the batteryplates,the batteryisthe "heart",is divided intothe positive electrode plate,a negative electrodeplate.
2,the role ofthe separatoris to isolatethe positiveand negative plates,to preventa short circuit,can be called "the third electrode."Itas an electrolytecarrier,canabsorb large amounts ofelectrolyte,goodplayiondiffusion(ion-conductive)role.Forsealed maintenance-freebatteries, theseparatoralso serves asa positive electrodeplateproducedoxygen to thenegative electrode plateofthe "channel"tosuccessfully establishoxygen cycle,to reducewaterloss.Ultra-fineglassfibers,aremaintenance-freebatterydiaphragmskey.
3,the electrolyteis mainlycomposedbywaterandsulfuric acid,together withsome of the additivemixture.
The mainfunctions: one isinvolved in the electrochemicalreaction,isone of the activesubstancesbattery;the second isfrom the conductive effect,byusing a transferwhenthe batteryelectrolyteionsplay aconductiverole, so thatthe chemical reactioncan proceed smoothly.
4, safetyis one ofthe key components ofthe battery,the batteryis locatedat the top,it has fourfunctions:
(1)the role ofsecurity,that is, whenthe gaspressureinsidethe batterygeneratedduring useto reachthe safety valvepressure,thepressure releasevalve openingand preventdeformation of the battery,ruptureoccurs.
(2)the sealing action,whenthebatterydownto theclosed-valve pressurerelief valvewhen thevalveis closed,to prevent theinternal gasmistleakedout,and also preventsair from entering thebatterycause adverse effects.
(3)ensure thatthe normalpressurewithin the battery,the batteryinside theoxygencomplexto promote,reducewater loss.
(4)the role ofproof,somesafety valveequipped with anti-acid-fat,anti-riotfilm.Such as Panasonicbatteries.
Many types ofvalvestructure, there arehat,umbrella,or flake.Whichis acommonhatraft,whichis made ofan elasticrubberinto agoodhat.Simple structure,the failure rate istoolow, sowidely used,such as Panasonic,Haibao, Advanced Micro Devices, days can, giantcellidentity.
Second, themaintenance experienceand principle
repairworks:
Fixelectronic, chemicaland physicalmethods.Chemical methodis a specialelectrolytic solution containing"active agent"chemical components(typicallytranslucent liquid)injected into thelead-acid battery,bychemical reactionto eliminatelead sulfatecrystalswithin the batterycurrentflowandpromoteregenerationof agedcellsandprolongits service life.
