【收割(ge)(ge)機電(dian)池(chi)(chi)】收割(ge)(ge)機蓄電(dian)池(chi)(chi)充(chong)電(dian)注意事(shi)項 收割(ge)(ge)機電(dian)池(chi)(chi)應急維修方法
很多收割機車主都認為蓄電池是一個很簡單的部件,平時也不太注意維護保養,其實在收割機使用中,蓄(xu)電池也是重要的(de)維護保養部件,馬虎(hu)不得。
蓄電(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)分快速充(chong)(chong)電(dian)(dian)(dian)(dian)和慢(man)(man)充(chong)(chong)電(dian)(dian)(dian)(dian)兩種, 一(yi)些收割(ge)機(ji)車主由于(yu)急(ji)于(yu)作業節省時間(jian)(jian),經常使(shi)用快速充(chong)(chong)電(dian)(dian)(dian)(dian),充(chong)(chong)電(dian)(dian)(dian)(dian)只(zhi)(zhi)需3~5 小(xiao)時,其實快速充(chong)(chong)電(dian)(dian)(dian)(dian)只(zhi)(zhi)是(shi)迅速把電(dian)(dian)(dian)(dian)池表面激(ji)活(huo),而實際上電(dian)(dian)(dian)(dian)池內部是(shi)沒(mei)有完(wan)全充(chong)(chong)滿電(dian)(dian)(dian)(dian)的。慢(man)(man)充(chong)(chong)電(dian)(dian)(dian)(dian)充(chong)(chong)電(dian)(dian)(dian)(dian)時間(jian)(jian)為10~15 小(xiao)時,這樣可以充(chong)(chong)分激(ji)活(huo)電(dian)(dian)(dian)(dian)池,使(shi)電(dian)(dian)(dian)(dian)池內部也(ye)完(wan)全充(chong)(chong)滿電(dian)(dian)(dian)(dian)。建議(yi)盡可能(neng)使(shi)用慢(man)(man)充(chong)(chong)電(dian)(dian)(dian)(dian)。
一、收割機蓄電池充電注意事項
1、充(chong)電時,蓄(xu)電池附(fu)近不能(neng)有火花,禁止(zhi)抽煙。
2、對一個或對多個蓄電(dian)池并聯充電(dian)時,充電(dian)器電(dian)壓不要超(chao)過16V。
3、將(jiang)充電器的正(zheng)極線(xian)接在(zai)蓄電池的正(zheng)極柱上,將(jiang)負(fu)極線(xian)接在(zai)蓄電池的負(fu)極柱上。
4、打開充電(dian)(dian)器時,先設(she)置到(dao)最低電(dian)(dian)流(liu),然后逐漸提高(gao)電(dian)(dian)流(liu),直(zhi)至蓄電(dian)(dian)池開始接(jie)受電(dian)(dian)流(liu)。如果(guo)是(shi)一個深度(du)放電(dian)(dian)后的蓄電(dian)(dian)池或是(shi)低溫下的蓄電(dian)(dian)池,這一過(guo)程可能(neng)需要好幾分鐘。
5、如(ru)果蓄(xu)(xu)電池排氣口排出酸霧(wu), 或(huo)蓄(xu)(xu)電池溫度(du)超過了52℃,充電需立刻停止,這(zhe)些現(xian)象表明該蓄(xu)(xu)電池已損壞,需要更(geng)換。
6.當電流降至(zhi)1A 以(yi)下時或(huo)充(chong)電超(chao)過(guo)24 小時后,表示充(chong)電完成,可以(yi)停止充(chong)電。
二、收割機電池應急維修方法
田(tian)間作業中突遇蓄電池損(sun)壞(huai)是十(shi)分惱火(huo)的事, 常使(shi)開車人措手不及。這里介紹2種在行駛途中蓄電池損(sun)壞(huai)的應急(ji)維修方(fang)法。
1、蓄電池斷路
蓄電池斷(duan)路(lu)分為(wei)內(nei)斷(duan)路(lu)和外(wai)斷(duan)路(lu)。內(nei)斷(duan)路(lu)可以用(yong)試火的(de)(de)(de)方式(shi)查找(zhao)出故障出在(zai)哪(na)一(yi)(yi)格。從正極樁柱上引1 根導(dao)線,逐(zhu)一(yi)(yi)單(dan)格向后試火,有火無火之(zhi)間為(wei)斷(duan)路(lu)處,用(yong)足(zu)夠粗的(de)(de)(de)導(dao)線跨過(guo)斷(duan)路(lu)的(de)(de)(de)單(dan)格即可發動(dong)。外(wai)部斷(duan)路(lu)時用(yong)眼能看(kan)出斷(duan)在(zai)哪(na)一(yi)(yi)格,其解(jie)決(jue)方法是一(yi)(yi)樣(yang)的(de)(de)(de)。
2、蓄電(dian)池(chi)樁頭斷掉
當蓄(xu)電(dian)(dian)池某(mou)一(yi)樁頭從膠木(mu)殼上(shang)(shang)面(mian)(mian)平齊斷(duan)(duan)掉(或低于膠木(mu)殼上(shang)(shang)平面(mian)(mian))時(shi),可(ke)用(yong)(yong)搭鐵(tie)線(xian)接(jie)在(zai)斷(duan)(duan)下的樁頭上(shang)(shang),然后(hou)一(yi)人用(yong)(yong)力壓緊在(zai)斷(duan)(duan)茬(cha)上(shang)(shang)(這樣(yang)原電(dian)(dian)壓、容量不(bu)(bu)變)。待(dai)發(fa)動(dong)機起動(dong)后(hou),再(zai)用(yong)(yong)1 根導線(xian)先(xian)將(jiang)搭鐵(tie)線(xian)接(jie)在(zai)斷(duan)(duan)樁頭那一(yi)格(ge)的另一(yi)樁柱上(shang)(shang),以保證收割機的正常用(yong)(yong)電(dian)(dian)和向蓄(xu)電(dian)(dian)池充電(dian)(dian), 然后(hou)可(ke)以松手理順加(jia)固(gu)電(dian)(dian)線(xian)。不(bu)(bu)論何種急(ji)(ji)救(jiu)方法,只能在(zai)作業中急(ji)(ji)救(jiu)時(shi)使用(yong)(yong),完成作業后(hou)一(yi)定要全面(mian)(mian)維修或更換,不(bu)(bu)得(de)再(zai)勉強使用(yong)(yong)。
三、收割機蓄電池日常維護保養
1、檢查蓄電池
使用過(guo)程中應(ying)經(jing)常清除蓄電池(chi)四周的灰塵泥土(tu),極(ji)樁上(shang)和導線接(jie)頭上(shang)的氧(yang)化物,擦去(qu)蓄電池(chi)蓋上(shang)的電解液,接(jie)線要牢固可靠(kao)。
經常檢查蓄電池在車上安裝是否牢(lao)固,保(bao)證導線接頭(tou)緊(jin)固,接觸良(liang)好。
2、禁止長時間大電流放(fang)電
起動(dong)(dong)發(fa)動(dong)(dong)機時,每次起動(dong)(dong)的時間(jian)不得超(chao)過(guo)5秒,相鄰兩次起(qi)動之(zhi)間應間隔15秒,同時不得長時間鳴(ming)電喇叭。
3、不能大電流(liu)充電
發電(dian)(dian)機(ji)調(diao)節器電(dian)(dian)壓調(diao)節值應嚴(yan)格(ge)按規定調(diao)整(zheng)。
實(shi)踐證明,充電電壓增高10%,蓄電池(chi)壽(shou)命將縮短2/3
4、充足電
蓄(xu)(xu)電池應(ying)經(jing)常進行充電,保證其(qi)在充足(zu)電的狀態下工作,放完電的蓄(xu)(xu)電池應(ying)在24小時內充足電(dian)。
5、冬季使用
冬季使(shi)用蓄電(dian)(dian)池時,要特別注意保持(chi)充足電(dian)(dian)狀態(tai),以免(mian)電(dian)(dian)解(jie)液因相(xiang)對密度降(jiang)低而結(jie)冰,致使(shi)殼體破裂。
6、儲存方法
蓄(xu)(xu)電(dian)池(chi)(chi)若(ruo)三個(ge)月(yue)不用時,應將蓄(xu)(xu)電(dian)池(chi)(chi)充足電(dian)后放于(yu)陰涼通風處。同時要定期檢(jian)查電(dian)解液的相對密度,保(bao)持蓄(xu)(xu)電(dian)池(chi)(chi)處于(yu)充足電(dian)的狀態。若(ruo)長期不用,先(xian)將蓄(xu)(xu)電(dian)池(chi)(chi)以20小時(shi)放電(dian)率放電(dian),倒(dao)出電(dian)解液,用蒸餾水(shui)多次沖洗,直(zhi)到水(shui)中無(wu)酸(suan)性(xing),涼干后(hou)旋緊(jin)孔蓋,密封儲存(cun)。
