液壓挖掘機行走操作及注意事項

2018/4/4

液(ye)壓挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)行(xing)走操(cao)作(zuo)(zuo)及注意事項如(ru)下1）挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)起步前(qian)(qian)應(ying)檢查(cha)環境安(an)全情(qing)況、清理(li)道路(lu)上(shang)的障(zhang)礙(ai)物，無關人員(yuan)離(li)開挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)，然后提升(sheng)鏟斗。2）準備工作(zuo)(zuo)結束后駕(jia)(jia)駛員(yuan)應(ying)先按喇叭，然后操(cao)作(zuo)(zuo)挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)起步。3）行(xing)走桿(gan)操(cao)作(zuo)(zuo)之前(qian)(qian)應(ying)先檢查(cha)履帶(dai)架的方向(xiang)(xiang)，盡量爭取(qu)挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)向(xiang)(xiang)前(qian)(qian)行(xing)走。如(ru)果驅動(dong)輪在前(qian)(qian)，行(xing)走桿(gan)應(ying)向(xiang)(xiang)后操(cao)作(zuo)(zuo)。4）如(ru)果行(xing)走桿(gan)在低(di)(di)速(su)(su)(su)(su)范圍內挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)起步，發(fa)動(dong)機(ji)(ji)轉速(su)(su)(su)(su)會突然升(sheng)高(gao)(gao)，因此駕(jia)(jia)駛員(yuan)要小(xiao)心操(cao)作(zuo)(zuo)行(xing)走桿(gan)菌。挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)倒車(che)時要留意車(che)后空(kong)間，注意挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)后面盲區，必(bi)要時請專人指揮(hui)予以協助。6）液(ye)壓挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)行(xing)走速(su)(su)(su)(su)度(du)--高(gao)(gao)速(su)(su)(su)(su)或低(di)(di)速(su)(su)(su)(su)可由駕(jia)(jia)駛員(yuan)選擇(ze)。當(dang)選擇(ze)開關在"0"位(wei)置時，挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)將低(di)(di)速(su)(su)(su)(su)、大(da)扭矩行(xing)走；當(dang)選擇(ze)開頭(tou)在"1"位(wei)置時，挖(wa)(wa)掘(jue)(jue)(jue)機(ji)(ji)行(xing)走速(su)(su)(su)(su)度(du)將根據液(ye)壓行(xing)走回路(lu)工作(zuo)(zuo)壓力(li)而(er)自(zi)動(dong)升(sheng)高(gao)(gao)或下降(jiang)。
例(li)如，挖(wa)(wa)掘(jue)機(ji)(ji)在平地(di)(di)上(shang)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)可(ke)選(xuan)擇(ze)高速(su)；上(shang)坡(po)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)時(shi)(shi)可(ke)選(xuan)擇(ze)低速(su)。如果(guo)發動(dong)機(ji)(ji)速(su)度控(kong)制盤(pan)設定(ding)在發動(dong)機(ji)(ji)中速(su)（約1400r/min）以下，即使(shi)選(xuan)擇(ze)開關在"1"位(wei)置上(shang)，挖(wa)(wa)掘(jue)機(ji)(ji)仍會(hui)以低速(su)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)。7）挖(wa)(wa)掘(jue)機(ji)(ji)應(ying)(ying)盡可(ke)能在平地(di)(di)上(shang)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)，并避免(mian)上(shang)部轉臺自(zi)行(xing)(xing)(xing)(xing)放置或(huo)操縱其回(hui)轉。8）挖(wa)(wa)掘(jue)機(ji)(ji)在不(bu)(bu)良地(di)(di)面(mian)(mian)(mian)上(shang)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)時(shi)(shi)應(ying)(ying)避免(mian)巖石碰壞行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)馬達(da)和履帶(dai)架(jia)。泥砂、石子(zi)進入履帶(dai)會(hui)場影響(xiang)挖(wa)(wa)掘(jue)機(ji)(ji)正常行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)及(ji)履帶(dai)的使(shi)用壽命。挖(wa)(wa)掘(jue)機(ji)(ji)在坡(po)道上(shang)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)時(shi)(shi)應(ying)(ying)履帶(dai)方向和地(di)(di)面(mian)(mian)(mian)條件，使(shi)挖(wa)(wa)掘(jue)機(ji)(ji)盡可(ke)能直線行(xing)(xing)(xing)(xing)駛(shi)；保持鏟(chan)斗離地(di)(di)20-30cm，如果(guo)挖(wa)(wa)掘(jue)機(ji)(ji)打滑(hua)或(huo)不(bu)(bu)穩定(ding)，應(ying)(ying)立即放下鏟(chan)斗；當發動(dong)機(ji)(ji)在坡(po)道上(shang)熄火時(shi)(shi)，應(ying)(ying)降低鏟(chan)斗至地(di)(di)面(mian)(mian)(mian)，將控(kong)制桿置于中位(wei)，然后重(zhong)新啟動(dong)發動(dong)機(ji)(ji)。10）盡量避免(mian)挖(wa)(wa)掘(jue)機(ji)(ji)涉水(shui)(shui)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)。必須涉水(shui)(shui)行(xing)(xing)(xing)(xing)走(zou)(zou)(zou)時(shi)(shi)應(ying)(ying)先考察水(shui)(shui)下地(di)(di)面(mian)(mian)(mian)狀(zhuang)況(kuang)，且水(shui)(shui)面(mian)(mian)(mian)不(bu)(bu)宜超過支(zhi)重(zhong)輪(lun)的上(shang)邊緣(yuan)。
