Zita reChirungu revharuvhu-regulated lead-acid bhatiri iValve Regulated Lead Battery (VRLA bhatiri kwenguva pfupi).Pane imwe-nzira yekupedza vharafu (inonziwo vharafu yekuchengetedza) pavhavha.Basa revhavha iyi nderekuburitsa gasi kana huwandu hwegasi mukati mebhatiri hunodarika imwe kukosha (inowanzo kuratidzwa nemhepo yekumanikidza kukosha), ndiko kuti, kana mhepo yemhepo mukati mebhatiri ichikwira kune imwe kukosha.Ivhavhavha yegesi inovhura yega kuti ibudise gasi, uye yobva yavhara yegavhavha kudzivirira mweya kupinda mukati mebhatiri.
Kuoma kwekuvhara mabhatiri e-lead-acid ndiyo electrolysis yemvura panguva yekuchaja.Kana kutengesa kunosvika kune imwe voltage (kazhinji pamusoro pe 2.30V / sero), okisijeni inosunungurwa pa electrode yakanaka yebhatiri, uye hydrogen inosunungurwa pamagetsi asina kunaka.Kune rumwe rutivi, gasi rinobudiswa rinobudisa mhute ine acid kuti isvibise nharaunda;Valve-regulated lead-acid bhatiri chigadzirwa chakagadziridzwa kukunda kukanganisa uku.Zvigadzirwa zvayo ndezvi:
(1) Multi-element yepamusoro-mhando grid alloy inoshandiswa kuvandudza kuwanda kwekuburitswa kwegasi.Kureva kuti, yakajairika bhatiri grid alloy inoburitsa gasi kana iri pamusoro pe2.30V/sero (25°C).Mushure mekushandisa yakakwirira-yemhando yakawanda-yakasanganiswa alloys, gasi inoburitswa kana tembiricha iri pamusoro pe2.35V/monomer (25°C), iyo inoderedza huwandu hwegasi inoburitswa.
(2) Rega iyo yakaipa electrode iwedzere simba, kureva, 10% yakawanda simba pane iyo yakanaka electrode.Muchikamu chekupedzisira chekuchaja, iyo okisijeni inoburitswa neiyo yakanaka electrode inobata electrode isina kunaka, inobata, uye inovandudza mvura, kureva, O2+2Pb→2PbO+2H2SO4→H2O+2PbSO4, kuitira kuti electrode isina kunaka ive munzvimbo isingachaji. nekuda kwekuita kweokisijeni, saka hapana hydrogen inogadzirwa.Okisijeni ye electrode yakanaka inobatwa nemutungamiri we electrode isina kunaka, uyezve inoshandurwazve mumvura, iyo inonzi cathode absorption.
(3) Kuitira kubvumidza iyo okisijeni inoburitswa nechakanaka electrode kuyerera ichienda kune iyo yakaipa electrode nekukurumidza, mhando nyowani yeultra-fine glass fiber separator yakasiyana neiyo microporous rabha separator inoshandiswa mumabhatiri e-lead-asidi akajairwa. inofanira kushandiswa.porosity yaro inowedzerwa kubva pa50% yerubber separator kusvika kune inopfuura 90%, kuitira kuti okisijeni inogona kuyerera nyore kune yakaipa electrode uye yozoshandurwa kuita mvura.Pamusoro pezvo, iyo ultra-fine glass fiber separator ine basa rekushambadza sulfuric acid electrolyte, saka kunyangwe bhatiri rikadonha, electrolyte haifashukire.
(4) Iyo yakavharwa valve-inodzorwa asidi sefa chimiro inogamuchirwa, kuitira kuti asidhi mhute isakwanise kupukunyuka, kuitira kuti iwane chinangwa chekuchengetedza uye kuchengetedzwa kwezvakatipoteredza.
Mune yambotaurwa pamusoro cathode absorption process, sezvo mvura inogadzirwa haigone kufashukira pasi pechisimbiso, iyo valve-inodzorwa sealed lead-asidi bhatiri inogona kusunungurwa kubva pakuwedzera kwekuchengetedza mvura, inova zvakare mabviro evhavha-inodzorwa yakavharwa lead. -asidhi bhatiri inonzi dimension-isina bhatiri.Zvisinei, zvinoreva kuchengetedza-pasina hazvirevi kuti hapana kugadzirisa kunoitwa.Pane zvinopesana, kuitira kuvandudza hupenyu hwebasa hwemabhatiri eVRLA, kune mabasa akawanda ekugadzirisa akamirira kuti tiite.Iyo chaiyo yekushandisa nzira inogona kuongororwa chete panguva yekuita.huya kunze.
Kushanda kwemagetsi kwemabhatiri e-lead-asidhi kunoyerwa neanotevera parameters: bhatiri electromotive force, open circuit voltage, termination voltage, working voltage, discharge current, capacity, battery internal resistance, storage performance, service life (float life, charge and discharge. cycle life), nezvimwewo.
