首先將電池的正極連接到電源的正極，電池的負極連接到電源的負極。挖掘機修理最初挖掘機是手動的，從發明到現在已經有一百三十多年了，期間經歷了由蒸汽驅動斗回轉挖掘機到電力驅動和內燃機驅動回轉挖掘機、應用機電液一體化技術的全自動液壓挖掘機的逐步發展過程。挖掘機維修最重要的三個參數：操作重量（質量），發動機功率和鏟斗斗容。修理挖掘機常見的挖掘機(ji)結構(gou)包括，動力裝置，工(gong)作裝置，回轉機(ji)構(gou)，操縱機(ji)構(gou)，傳動機(ji)構(gou)，行走(zou)機(ji)構(gou)和輔助設(she)施等(deng)。 當電池進行初始充(chong)(chong)電或充(chong)(chong)電時(shi)，如(ru)果沒(mei)有注意極性，電池的充(chong)(chong)電能力將(jiang)不(bu)足，無法正常工(gong)作，甚至導致電池報廢。 所以充(chong)(chong)電時(shi)一定要注意極性，千萬不(bu)能極性充(chong)(chong)電回來..

2，初始充(chong)(chong)(chong)(chong)電(dian)在兩個階段：先(xian)用(yong)的(de)初始充(chong)(chong)(chong)(chong)電(dian)電(dian)流充(chong)(chong)(chong)(chong)電(dian)到(dao)電(dian)解液放(fang)出氣(qi)泡，單電(dian)池(chi)電(dian)壓上升2.3?2.4V，直到(dao)電(dian)流降低到(dao)初始的(de)1/2的(de)充(chong)(chong)(chong)(chong)電(dian)電(dian)流繼(ji)續(xu)充(chong)(chong)(chong)(chong)電(dian)到(dao)電(dian)解質。釋放(fang)劇烈氣(qi)泡，和本征(zheng)穩(wen)定性常(chang)數的(de)比(bi)率，直到(dao)電(dian)壓連續(xu)地為3h。完(wan)全充(chong)(chong)(chong)(chong)電(dian)時間約為45?65H。

3、充(chong)電(dian)(dian)管理過程中應常測量(liang)電(dian)(dian)解液(ye)反應溫度用電(dian)(dian)流可(ke)以減半、停止自(zi)己充(chong)電(dian)(dian)或冷(leng)卻的方法,將溫度影響控(kong)制(zhi)在(zai)35~40℃,初充(chong)電(dian)(dian)學習完畢時若(ruo)電(dian)(dian)解液(ye)比(bi)重已經不合(he)法律(lv)規(gui)定(ding),應用蒸(zheng)餾水或比(bi)重為1.4的電(dian)(dian)解液(ye)系統進行分析調整.調整后再充(chong)電(dian)(dian)2h,直至比(bi)重是否(fou)符合(he)規(gui)定(ding)時為止.

一(yi)般充電方(fang)式(shi)(shi)分為恒流(liu)充電方(fang)式(shi)(shi)和恒壓充電方(fang)式(shi)(shi)，上述充電方(fang)式(shi)(shi)為推薦的恒流(liu)充電方(fang)式(shi)(shi)..

恒(heng)(heng)壓(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)方法其實(shi)就(jiu)是我們日常所說的(de)快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)，其特點是充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)保(bao)持(chi)在(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)過程(cheng)中保(bao)持(chi)不變。恒(heng)(heng)壓(ya)(ya)(ya)充(chong)(chong)(chong)電(dian)(dian)(dian)開始(shi)，由(you)于電(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)動勢低(di)，則(ze)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)(ya)，該電(dian)(dian)(dian)壓(ya)(ya)(ya)越大，大的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流，在(zai)電(dian)(dian)(dian)池快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)速(su)度的(de)值之間的(de)差可以為1?5小(xiao)時或(huo)接近滿充(chong)(chong)(chong)電(dian)(dian)(dian)狀(zhuang)態時，常用(yong)的(de)牽引電(dian)(dian)(dian)池需要充(chong)(chong)(chong)電(dian)(dian)(dian)，在(zai)短時間內恢(hui)復(fu)更完全充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)狀(zhuang)態，但(dan)快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)有損電(dian)(dian)(dian)池性能和(he)壽(shou)命(ming)，所以這種(zhong)方法適用(yong)于緊急情況下使用(yong)普通充(chong)(chong)(chong)電(dian)(dian)(dian)，初次充(chong)(chong)(chong)電(dian)(dian)(dian)對和(he)電(dian)(dian)(dian)荷(he)消除硫化物不太適合。

定流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)法的(de)(de)(de)特(te)點(dian)是在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)管理過程中,保持自己(ji)選(xuan)定的(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)不(bu)變.由于定流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)所(suo)(suo)用充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)技術(shu)設備(bei)(bei)的(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)我們可以(yi)(yi)有(you)效調節,所(suo)(suo)以(yi)(yi)能通過不(bu)斷改變傳統充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)來選(xuan)擇一個合適的(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu),這(zhe)一點(dian)很(hen)(hen)重要,因(yin)為企業各(ge)種蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(如(ru)新蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)、正常使用蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)、有(you)故障的(de)(de)(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)及電(dian)(dian)(dian)(dian)荷量各(ge)異的(de)(de)(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)等)所(suo)(suo)需要的(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)是不(bu)同(tong)的(de)(de)(de).另(ling)外,定流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)所(suo)(suo)用充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)設施設備(bei)(bei)信息能夠(gou)以(yi)(yi)很(hen)(hen)小的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)數據進行(xing)研究充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian),這(zhe)對(dui)于已基本沒(mei)有(you)充(chong)(chong)(chong)(chong)足電(dian)(dian)(dian)(dian)的(de)(de)(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)來說,能夠(gou)同(tong)時(shi)(shi)使其(qi)極(ji)板內(nei)部因(yin)素較(jiao)多的(de)(de)(de)活(huo)性(xing)物(wu)質參(can)加一些化學實驗(yan)反應,所(suo)(suo)以(yi)(yi)為了能使蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)問(wen)題比較(jiao)全面徹底(di),但定流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)需經(jing)常調節充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya),且充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)服務時(shi)(shi)間相對(dui)較(jiao)長.
