Dzina lachingerezi la batire ya lead-acid yoyendetsedwa ndi ma valve ndi Battery Yotsogolera Yoyendetsedwa ndi Valve (batire ya VRLA mwachidule).Pali valavu yotulutsa njira imodzi (yomwe imatchedwanso valavu yotetezera) pachivundikirocho.Ntchito ya valve iyi ndikutulutsa mpweya pamene kuchuluka kwa mpweya mkati mwa batri kumaposa mtengo wina (kawirikawiri umasonyezedwa ndi mtengo wa mpweya), ndiko kuti, pamene kuthamanga kwa mpweya mkati mwa batri kumakwera mtengo.Valavu ya gasi imatsegula yokha kuti itulutse mpweya, ndiyeno imatseka valavu kuti mpweya usalowe mkati mwa batri.
Kuvuta kwa kusindikiza mabatire a lead-acid ndi electrolysis yamadzi panthawi yolipira.Kuthamanga kukafika pamagetsi ena (nthawi zambiri pamwamba pa 2.30V / selo), mpweya umatulutsidwa pa electrode yabwino ya batri, ndipo haidrojeni imatulutsidwa pa electrode yolakwika.Kumbali imodzi, mpweya wotulutsidwa umatulutsa nkhungu ya asidi kuti iwononge chilengedwe;Batire ya asidi ya lead yoyendetsedwa ndi ma valve ndi chinthu chopangidwa kuti chigonjetse zofooka izi.Zogulitsa zake ndi:
(1) Multi-element grid alloy apamwamba kwambiri amagwiritsidwa ntchito kupititsa patsogolo kutulutsa kwa gasi.Ndiye kuti, aloyi wamba wa batire amatulutsa mpweya ukakhala pamwamba pa 2.30V/cell (25°C).Pambuyo pogwiritsira ntchito ma alloys apamwamba kwambiri, mpweya umatulutsidwa pamene kutentha kuli pamwamba pa 2.35V / monomer (25 ° C), zomwe zimachepetsanso kuchuluka kwa mpweya wotulutsidwa.
(2) Lolani ma elekitirodi olakwika akhale ndi mphamvu zambiri, ndiye kuti, 10% mphamvu zambiri kuposa electrode yabwino.Pambuyo pake, mpweya wotulutsidwa ndi elekitirodi yabwino umalumikizana ndi electrode yolakwika, imagwira, ndi kutulutsanso madzi, ndiye kuti, O2+2Pb→2PbO+2H2SO4→H2O+2PbSO4, kotero kuti electrode yolakwikayo imakhala yopandacharge. chifukwa cha ntchito ya okosijeni, kotero palibe haidrojeni yomwe imapangidwa.Mpweya wa electrode wabwino umatengedwa ndi kutsogolera kwa electrode yoipa, ndiyeno imasinthidwa kukhala madzi, omwe amatchedwa cathode mayamwidwe.
(3) Pofuna kulola mpweya wotulutsidwa ndi elekitirodi yabwino kuyenda kwa elekitirodi zoipa posachedwapa, mtundu watsopano wa kopitilira muyeso galasi CHIKWANGWANI cholekanitsa kuti ndi wosiyana ndi microporous mphira olekanitsa ntchito mabatire wamba lead-asidi. ziyenera kugwiritsidwa ntchito.Porosity yake imachulukitsidwa kuchokera ku 50% ya cholekanitsa mphira kupita ku 90%, kotero kuti mpweya ukhoza kuyenda mosavuta kupita ku electrode yoyipa ndikusinthidwa kukhala madzi.Kuphatikiza apo, cholekanitsa magalasi apamwamba kwambiri amakhala ndi ntchito yotsatsa ma electrolyte a sulfuric acid, kotero ngakhale batire itagwetsedwa, electrolyte sidzasefukira.
(4) Chosindikizira valavu-olamulidwa ndi asidi fyuluta dongosolo anatengera, kuti asidi nkhungu sangathe kuthawa, kuti akwaniritse cholinga cha chitetezo ndi kuteteza chilengedwe.
M'mayamwidwe a cathode omwe tatchulawa, popeza madzi opangidwa sangathe kusefukira pansi pa kusindikizidwa, batire ya acid-acid yoyendetsedwa ndi valavu imatha kumasulidwa pakukonza madzi owonjezera, omwenso ndi chiyambi cha chiwongolero chosindikizidwa choyendetsedwa ndi ma valve. -acid batire yotchedwa dimension-free batire.Komabe, tanthauzo la kusakonza sikukutanthauza kuti palibe kukonza komwe kumachitika.M'malo mwake, pofuna kupititsa patsogolo moyo wautumiki wa mabatire a VRLA, pali ntchito zambiri zokonzekera zomwe zikutiyembekezera kuti tichite.Njira yoyenera yogwiritsira ntchito ikhoza kufufuzidwa panthawiyi.tuluka.
Mphamvu yamagetsi ya mabatire a lead-acid imayesedwa ndi magawo otsatirawa: mphamvu ya batri ya electromotive, voltage yotseguka, voltage yomaliza, voliyumu yogwira ntchito, magetsi otulutsa, mphamvu, kukana kwa batire mkati, kusungirako, moyo wautumiki (moyo woyandama, mtengo ndi kutulutsa. moyo wozungulira), etc.
