A 12-volt lead acid roj teeb yog ib hom roj teeb rechargeable uas feem ntau siv rau ntau yam kev siv. Cov roj teeb no paub txog lawv cov kav ntev, lub neej ntev, thiab kev ntseeg siab, uas yog vim li cas lawv nyiam dua lwm hom roj teeb.
Hauv tsab xov xwm no, peb yuav tham txog dab tsi 12-volt lead acid roj teeb yog dab tsi, nws ua haujlwm li cas, nws qhov zoo thiab qhov tsis zoo, thiab nws cov ntawv thov.
12-volt lead acid roj teeb yog dab tsi?
A 12-volt lead acid roj teeb yog ib hom roj teeb uas siv tau uas muaj cov hlau lead rau hauv cov tshuaj electrolyte uas ua los ntawm sulfuric acid thiab dej. Lub roj teeb feem ntau yog nyob rau hauv ib lub hnab yas kaw los yog hlau.
Cov phaj hlau lead yog cov khoom tseem ceeb ntawm lub roj teeb thiab yog lub luag haujlwm rau kev tsim thiab khaws cov hluav taws xob hluav taws xob. Lawv tau coated nrog cov tshuaj zoo li cov tshuaj hu ua lead dioxide, uas cuam tshuam nrog sulfuric acid thiab dej tov los tsim hluav taws xob.
Lub roj teeb muaj rau lub hlwb tau teeb tsa hauv ib qho, nrog rau txhua lub xov tooj tsim tawm 2.1 volts ntawm hluav taws xob. Qhov no ua rau tag nrho cov zis tawm ntawm 12.6 volts.
12-volt lead acid roj teeb ua haujlwm li cas?
A 12-volt lead acid roj teeb ua haujlwm los ntawm kev hloov tshuaj lub zog rau hauv hluav taws xob. Thaum lub roj teeb tau them tag nrho, cov hlau lead yog coated nyob rau hauv cov hlau lead dioxide thiab lead sulfate, uas yog cov roj teeb uas them tag nrho.
Thaum lub roj teeb tawm lawm, cov hlau lead dioxide thiab cov hlau lead sulfate tau hloov mus rau hauv cov hlau lead thiab txhuas sulfate los ntawm kev tso cov hluav taws xob los tsim hluav taws xob. Cov txheej txheem no tso tawm sulfuric acid thiab dej rau hauv cov tshuaj electrolyte, uas maj mam txo cov concentration ntawm sulfuric acid hauv cov tshuaj.
Raws li qhov concentration ntawm sulfuric acid nyob rau hauv cov tshuaj txo, lub roj teeb voltage tso zis kuj txo. Thaum lub roj teeb tau tso tawm tag nrho, cov hlau lead daim hlau yog coated nyob rau hauv txhuas sulfate, uas yog tag nrho lub xeev tawm ntawm lub roj teeb.
Qhov zoo ntawm 12-volt lead acid roj teeb
Muaj ntau qhov zoo ntawm 12-volt lead acid roj teeb, uas suav nrog:
1. Lub neej ntev: Cov roj ntsha lead acid muaj lub neej ntev dua li lwm hom roj teeb, uas txhais tau tias lawv tuaj yeem siv tau ntau xyoo ua ntej yuav tsum tau hloov.
2. Durability: Lead acid roj teeb muaj zog thiab tuaj yeem tiv taus qhov hnyav xws li qhov kub thiab txias thiab kev co. Qhov no ua rau lawv zoo tagnrho rau siv hauv tsheb, kev lag luam, thiab kev siv dej hiav txwv.
3. Tus nqi siv tau: Cov roj teeb lead acid kuj pheej yig dua piv rau lwm hom roj teeb, uas ua rau lawv xaiv kev lag luam rau ntau daim ntawv thov.
4. Kev saib xyuas tsis tshua muaj: Cov roj ntsha lead acid yuav tsum tau saib xyuas me ntsis thiab tuaj yeem rov qab siv lub charger txheem.
Qhov tsis zoo ntawm 12-volt lead acid roj teeb
Kuj tseem muaj qee qhov tsis zoo ntawm 12-volt lead acid roj teeb, uas suav nrog:
1. Nyhav: Lead acid roj teeb hnyav thiab tuaj yeem txav mus los tsis yooj yim. Qhov no ua rau lawv tsis tshua zoo tagnrho rau cov ntawv thov portable.
2. Kev txhawj xeeb txog kev nyab xeeb: Cov roj ntsha lead acid muaj sulfuric acid, uas tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv yog tias tsis ua raws cai. Lawv kuj emit cov pa phem thaum lawv raug them.
3. Txwv tsis pub dhau lub voj voog rov qab: Cov roj ntsha lead acid muaj qhov txwv tsis pub dhau lub voj voog, uas txhais tau tias lawv yuav tsum tau hloov mus rau qhov kawg.
Daim ntawv thov ntawm 12-volt lead acid roj teeb
Muaj ntau daim ntawv thov ntawm 12-volt lead acid roj teeb, uas suav nrog:
1. Automotive: Cov roj teeb lead acid feem ntau yog siv hauv tsheb los ua lub zog rau lub cev muaj zog, lub teeb, thiab lwm yam khoom siv hluav taws xob.
2. Kev lag luam: Cov roj ntsha lead acid yog siv rau hauv cov ntawv thov kev lag luam rau lub zog hluav taws xob forklifts, pem teb sweepers, thiab lwm yam khoom siv.
3. Marine: Cov roj ntsha lead acid yog siv rau hauv marine daim ntawv thov rau lub nkoj fais fab, yachts, thiab lwm yam dej hiav txwv.
4. Hnub ci zog: Cov roj teeb lead acid feem ntau yog siv rau hauv lub hnub ci zog los khaws lub zog ntawm lub hnub ci vaj huam sib luag.
