3、常見故(gu)障(zhang)：滿負荷時，液力(li)偶合器不能傳遞額(e)定(ding)力(li)矩。故(gu)障(zhang)原因分析：液力(li)偶合器油(you)(you)量不足(zu)。處(chu)理方法(fa)：加油(you)(you)（當雙電機驅動(dong)時，必須(xu)用電流表測量兩電動(dong)機。通(tong)過(guo)調查充油(you)(you)量使功(gong)率趨向一致(zhi)。）

4、常見故障：減速器過(guo)(guo)熱。故障原因分析：減速器中油量過(guo)(guo)多(duo)或太少；油使(shi)用時(shi)間過(guo)(guo)長；潤(run)(run)滑條(tiao)件惡(e)化，使(shi)軸承(cheng)損(sun)壞。處理方法：按規(gui)定(ding)量注油；清洗(xi)內(nei)部，及時(shi)換油修理或更換軸承(cheng)、改(gai)善潤(run)(run)滑條(tiao)件。

5、常見(jian)故障：輸(shu)(shu)送帶(dai)(dai)(dai)跑(pao)偏(pian)。故障原因(yin)分(fen)析：機架、滾筒沒有調(diao)(diao)(diao)(diao)整平直(zhi)；托輥軸(zhou)線與輸(shu)(shu)送帶(dai)(dai)(dai)中(zhong)(zhong)心線不垂(chui)直(zhi)；輸(shu)(shu)送帶(dai)(dai)(dai)接(jie)頭與中(zhong)(zhong)心線不垂(chui)直(zhi)，輸(shu)(shu)送帶(dai)(dai)(dai)邊呈S型；裝載點(dian)(dian)不在輸(shu)(shu)送帶(dai)(dai)(dai)中(zhong)(zhong)央(yang)（偏(pian)載）。處(chu)理方法(fa)：調(diao)(diao)(diao)(diao)整在機架或滾筒，使(shi)之(zhi)保持(chi)平直(zhi)；利用托輥調(diao)(diao)(diao)(diao)位，糾正輸(shu)(shu)送帶(dai)(dai)(dai)跑(pao)偏(pian)；重(zhong)新做接(jie)頭，保證接(jie)頭與輸(shu)(shu)送帶(dai)(dai)(dai)中(zhong)(zhong)心垂(chui)直(zhi)；調(diao)(diao)(diao)(diao)整落煤點(dian)(dian)位置(zhi)。

6、常見故障(zhang)：輸(shu)送(song)(song)(song)帶(dai)老(lao)(lao)化、撕(si)裂(lie)。故障(zhang)原(yuan)因分析：輸(shu)送(song)(song)(song)帶(dai)與機架(jia)摩擦，產(chan)生帶(dai)邊(bian)拉毛(mao)，開裂(lie)；輸(shu)送(song)(song)(song)帶(dai)與固定(ding)硬物干涉產(chan)生撕(si)裂(lie)；保管(guan)不善，張緊力(li)過(guo)大；鋪(pu)設(she)過(guo)短產(chan)生撓曲(qu)次數(shu)超(chao)過(guo)限(xian)值(zhi)，產(chan)生提前老(lao)(lao)化。處(chu)理(li)方法：儀器儀表網建(jian)議及時調整，避免輸(shu)送(song)(song)(song)帶(dai)長期跑(pao)偏；防(fang)止輸(shu)送(song)(song)(song)帶(dai)掛到固定(ding)構件上或輸(shu)送(song)(song)(song)帶(dai)中掉進(jin)金屬結構件；按輸(shu)送(song)(song)(song)帶(dai)保管(guan)要(yao)求貯存；盡量避免短距離(li)鋪(pu)設(she)使用。

7、常(chang)(chang)見(jian)故障：斷帶。故障原因分析：帶體材質不(bu)(bu)適應，遇(yu)水、遇(yu)冷變硬脆；輸(shu)送帶長期使(shi)用，強度變差；輸(shu)送帶接頭(tou)質量(liang)不(bu)(bu)佳，局部開裂未及(ji)(ji)(ji)時修復或重(zhong)打。處(chu)理方法：選用機械(xie)物理性能(neng)穩定(ding)的材質制(zhi)做(zuo)帶芯；及(ji)(ji)(ji)時更換破損或老化的輸(shu)送帶；對(dui)接頭(tou)經常(chang)(chang)觀察，發(fa)現問(wen)題及(ji)(ji)(ji)時處(chu)理。

8、常見故(gu)障：打滑。故(gu)障原因分析(xi)：輸送(song)帶(dai)漲緊(jin)力(li)不足(zu)，負載過大；由于淋水(shui)使傳動滾(gun)筒與輸送(song)帶(dai)之間摩擦系數降低(di)；超出使用范圍，傾斜向下運(yun)輸。處(chu)(chu)理方法：重新調整(zheng)張(zhang)緊(jin)力(li)或(huo)者減(jian)少運(yun)輸量；消除(chu)淋水(shui)，增大漲緊(jin)力(li)；對接頭經常觀察(cha)，發(fa)現問題及時處(chu)(chu)理。
