卡特挖掘機維修
CAT365BⅡ大型挖(wa)機(ji)(ji)(ji)(ji)(ji)，短臂型的(de)(de)斗(dou)容可達4立方。功率大。工作效率高(gao)。采(cai)用卡特(te)的(de)(de)3196發(fa)動(dong)機(ji)(ji)(ji)(ji)(ji)，此型號發(fa)動(dong)機(ji)(ji)(ji)(ji)(ji)是電(dian)(dian)噴(pen)柴油(you)機(ji)(ji)(ji)(ji)(ji)，缸徑(jing)130mm，行程150mm，排氣量(liang)12L，功率365KW。采(cai)用機(ji)(ji)(ji)(ji)(ji)械促動(dong)的(de)(de)電(dian)(dian)子(zi)(zi)控制單體(ti)式噴(pen)油(you)器(qi)（EUI）的(de)(de)燃(ran)油(you)系統(tong)，EUI單體(ti)式噴(pen)油(you)器(qi)由(you)凸(tu)輪軸(zhou)產(chan)生的(de)(de)機(ji)(ji)(ji)(ji)(ji)械力用來產(chan)生高(gao)噴(pen)射壓力，該裝置將泵吸(xi)元(yuan)件。電(dian)(dian)子(zi)(zi)式的(de)(de)燃(ran)油(you)計量(liang)元(yuan)件和噴(pen)油(you)元(yuan)件組合在一個單獨的(de)(de)裝置中，由(you)發(fa)動(dong)機(ji)(ji)(ji)(ji)(ji)電(dian)(dian)子(zi)(zi)控制模塊（ECM）根(gen)據(ju)機(ji)(ji)(ji)(ji)(ji)車(che)主控制電(dian)(dian)腦(nao)板發(fa)送的(de)(de)油(you)門(men)信(xin)(xin)號。及各發(fa)動(dong)機(ji)(ji)(ji)(ji)(ji)傳(chuan)感器(qi)的(de)(de)信(xin)(xin)號。再給出正確的(de)(de)脈沖信(xin)(xin)號到電(dian)(dian)子(zi)(zi)控制單體(ti)式噴(pen)油(you)器(qi)（EUI）的(de)(de)電(dian)(dian)磁線圈。
激活噴(pen)(pen)油(you)(you)(you)器噴(pen)(pen)油(you)(you)(you)，產生合適(shi)的(de)(de)發動(dong)(dong)機(ji)轉速。電(dian)(dian)(dian)控(kong)系(xi)統整(zheng)體設計到發動(dong)(dong)機(ji)燃(ran)油(you)(you)(you)系(xi)統和(he)(he)發動(dong)(dong)機(ji)進(jin)排氣系(xi)統中，以(yi)便(bian)對燃(ran)油(you)(you)(you)輸(shu)送和(he)(he)噴(pen)(pen)油(you)(you)(you)正時進(jin)行(xing)電(dian)(dian)(dian)子控(kong)制(zhi)，和(he)(he)常規的(de)(de)機(ji)械式發動(dong)(dong)機(ji)相比，電(dian)(dian)(dian)控(kong)系(xi)統能提供增(zeng)強(qiang)的(de)(de)正時控(kong)制(zhi)和(he)(he)燃(ran)油(you)(you)(you)空氣混合比控(kong)制(zhi)。噴(pen)(pen)油(you)(you)(you)正時通過噴(pen)(pen)油(you)(you)(you)點火時間的(de)(de)精(jing)確控(kong)制(zhi)來實現。發動(dong)(dong)機(ji)每分(fen)鐘轉速通過調(diao)整(zheng)噴(pen)(pen)油(you)(you)(you)的(de)(de)持續時間來控(kong)制(zhi)。燃(ran)油(you)(you)(you)的(de)(de)噴(pen)(pen)射壓力可以(yi)高達30，000psi（約2100kg/cm2）,使(shi)燃(ran)油(you)(you)(you)霧化更好，排放更優良，此機(ji)型的(de)(de)電(dian)(dian)(dian)腦板有機(ji)車主控(kong)制(zhi)板。重要(yao)(yao)信息(xi)控(kong)制(zhi)板（VIDS）,發動(dong)(dong)機(ji)控(kong)制(zhi)板（ECM）, 因(yin)為手柄是電(dian)(dian)(dian)控(kong)手柄，發動(dong)(dong)機(ji)是電(dian)(dian)(dian)噴(pen)(pen)發動(dong)(dong)機(ji)，所以(yi)各種輸(shu)入輸(shu)出的(de)(de)電(dian)(dian)(dian)信號比一般的(de)(de)機(ji)型要(yao)(yao)多。
所以電(dian)腦板功能比較強大，監控(kong)器(qi)(qi)上有(you)參數鍵(jian)，可以調出(chu)機(ji)(ji)(ji)車(che)(che)及(ji)發(fa)動(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)(de)(de)許多(duo)重(zhong)要參數，如(ru)電(dian)控(kong)手(shou)柄的(de)(de)(de)(de)(de)輸出(chu)信號，主(zhu)控(kong)制閥(fa)上控(kong)制各機(ji)(ji)(ji)構(gou)動(dong)(dong)作的(de)(de)(de)(de)(de)先(xian)導比例(li)電(dian)磁閥(fa)的(de)(de)(de)(de)(de)電(dian)流值。主(zhu)泵(beng)及(ji)回轉泵(beng)的(de)(de)(de)(de)(de)動(dong)(dong)力換檔減壓(ya)閥(fa)的(de)(de)(de)(de)(de)電(dian)流。發(fa)動(dong)(dong)機(ji)(ji)(ji)的(de)(de)(de)(de)(de)各個重(zhong)要傳感器(qi)(qi)的(de)(de)(de)(de)(de)信號等，當發(fa)動(dong)(dong)機(ji)(ji)(ji)不能著(zhu)車(che)(che)，可能的(de)(de)(de)(de)(de)原因有(you)啟動(dong)(dong)電(dian)路的(de)(de)(de)(de)(de)問題，或(huo)燃油供給(gei)方面(mian)有(you)故(gu)障(zhang)。或(huo)有(you)機(ji)(ji)(ji)械故(gu)障(zhang)。一次(ci)在工地(di)上，遇(yu)到一臺CAT365BⅡ出(chu)現不能著(zhu)車(che)(che)的(de)(de)(de)(de)(de)故(gu)障(zhang)，司機(ji)(ji)(ji)反映機(ji)(ji)(ji)子夜班還干著(zhu)活，白班交班以后就打不著(zhu)車(che)(che)了(le)，因為(wei)是(shi)在正常停機(ji)(ji)(ji)的(de)(de)(de)(de)(de)情(qing)況下出(chu)現的(de)(de)(de)(de)(de)，有(you)機(ji)(ji)(ji)械故(gu)障(zhang)的(de)(de)(de)(de)(de)可能性很小。打開鑰匙鍵(jian)接通電(dian)源，如(ru)果有(you)電(dian)路故(gu)障(zhang)，在監控(kong)器(qi)(qi)的(de)(de)(de)(de)(de)信息顯示中(zhong)心(xin)會顯示故(gu)障(zhang)內容及(ji)故(gu)障(zhang)診(zhen)斷代碼。
