蓄(xu)電(dian)池(chi)叉車銷售廠家介紹電(dian)動叉車電(dian)瓶的(de)維護與電(dian)壓保(bao)護

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動叉車電(dian)(dian)(dian)(dian)(dian)(dian)(dian)瓶的(de)(de)(de)(de)(de)維護與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓保(bao)護存在很大(da)的(de)(de)(de)(de)(de)關(guan)聯，極板是(shi)超低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)式的(de)(de)(de)(de)(de)核心部分，蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程(cheng)中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能與化學能的(de)(de)(de)(de)(de)相互轉換依靠極板上的(de)(de)(de)(de)(de)活性物質與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液中的(de)(de)(de)(de)(de)硫(liu)酸的(de)(de)(de)(de)(de)化學反(fan)應來實(shi)現，為此,要求(qiu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)系統的(de)(de)(de)(de)(de)功能要全(quan)面,如具備定時均充(chong)、二(er)次下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)、溫度補償(chang)、無級(ji)限流等功能,同時必須建立完善的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)維護體系。除了定時均充(chong)外,蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)日(ri)常(chang)管理的(de)(de)(de)(de)(de)內(nei)容也是(shi)非常(chang)多(duo)的(de)(de)(de)(de)(de),包括低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓保(bao)護、二(er)次下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)、溫度補償(chang)、無級(ji)限流等等,這些措施(shi)可以(yi)保(bao)證蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)處于良好的(de)(de)(de)(de)(de)使(shi)用(yong)狀(zhuang)態(tai),延(yan)長其使(shi)用(yong)壽命。

電(dian)(dian)動叉車電(dian)(dian)瓶(ping)是由鉛銻合金澆(jiao)鑄(zhu)而(er)成(cheng)。銻可以提高機械強度和(he)澆(jiao)鑄(zhu)性(xing)能(neng)。但是銻會加速氫的析出而(er)加速電(dian)(dian)解液(ye)的消耗，還會引起蓄電(dian)(dian)池自放(fang)電(dian)(dian)和(he)柵架(jia)腐爛(lan)，縮短(duan)蓄電(dian)(dian)池使(shi)用壽命。蓄電(dian)(dian)池在輸出能(neng)量(liang)時(shi),其(qi)兩端(duan)電(dian)(dian)壓(ya)不斷下降,當下降到(dao)一定值(一般稱為終止電(dian)(dian)壓(ya))的時(shi)候,就必須斷掉其(qi)能(neng)量(liang)輸出回(hui)路,否則可能(neng)導致(zhi)蓄電(dian)(dian)池過放(fang)電(dian)(dian),使(shi)其(qi)壽命縮短(duan)甚(shen)至報廢(fei)。這(zhe)種在終止電(dian)(dian)壓(ya)時(shi)的使(shi)蓄電(dian)(dian)池斷掉負載(zai)防止過放(fang)電(dian)(dian)的動作和(he)措施,叫做(zuo)低電(dian)(dian)壓(ya)保護。

二次(ci)下電(dian)(dian)(dian)(dian)比低(di)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)保(bao)(bao)護更進一(yi)步。因為正極板的(de)(de)強度較低(di)，所以在(zai)單格(ge)電(dian)(dian)(dian)(dian)池中(zhong)，負(fu)極板總比正極板多(duo)一(yi)片。是(shi)每一(yi)片正極板都處于(yu)兩片負(fu)極板之間(jian)，保(bao)(bao)持(chi)其放電(dian)(dian)(dian)(dian)均勻，防止變形。當電(dian)(dian)(dian)(dian)池兩端電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)降到(dao)一(yi)定值時(shi)(shi)(一(yi)般比終(zhong)止電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)高),就(jiu)斷掉一(yi)部分(fen)次(ci)要(yao)負(fu)載(zai)(zai),只(zhi)給(gei)剩下的(de)(de)主(zhu)要(yao)負(fu)載(zai)(zai)供(gong)電(dian)(dian)(dian)(dian)。之后(hou)當電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)下降到(dao)終(zhong)止電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時(shi)(shi),則將主(zhu)要(yao)負(fu)載(zai)(zai)也斷掉,實現(xian)對蓄電(dian)(dian)(dian)(dian)池的(de)(de)保(bao)(bao)護。這種兩級斷開負(fu)載(zai)(zai)的(de)(de)動作和措施即為二次(ci)下電(dian)(dian)(dian)(dian)。二次(ci)下電(dian)(dian)(dian)(dian)的(de)(de)好處是(shi)在(zai)保(bao)(bao)證蓄電(dian)(dian)(dian)(dian)池不(bu)過放電(dian)(dian)(dian)(dian)的(de)(de)同時(shi)(shi),可(ke)以給(gei)重要(yao)設(she)備(bei)提供(gong)更長的(de)(de)供(gong)電(dian)(dian)(dian)(dian)時(shi)(shi)間(jian),盡量(liang)減(jian)少(shao)通(tong)信(xin)中(zhong)斷的(de)(de)損失。如果需要(yao)實現(xian)系統的(de)(de)二次(ci)下電(dian)(dian)(dian)(dian)功(gong)能(neng),開局時(shi)(shi),須(xu)將直流輸出負(fu)載(zai)(zai)分(fen)成(cheng)主(zhu)要(yao)和次(ci)要(yao)負(fu)載(zai)(zai),接到(dao)相應(ying)的(de)(de)分(fen)路上。先(xian)進的(de)(de)電(dian)(dian)(dian)(dian)源設(she)備(bei)的(de)(de)二次(ci)下電(dian)(dian)(dian)(dian)功(gong)能(neng)非常靈活(huo),可(ke)以隨意(yi)調節一(yi)、二次(ci)下電(dian)(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya),并且可(ke)以設(she)置(zhi)成(cheng)不(bu)做二次(ci)下電(dian)(dian)(dian)(dian)和低(di)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)保(bao)(bao)護,滿(man)足優先(xian)保(bao)(bao)障通(tong)信(xin)的(de)(de)需求。
