隨著科技的進步，現(xiàn)代挖掘機一般都采用了機—電—液一體化控制模式，我們在排除一些故障時，解決的多是發(fā)動機—液壓泵—分配閥—外部負荷的匹配問題。一般在挖掘機作業(yè)中，這幾方面不能匹配，經(jīng)常會表現(xiàn)為：發(fā)動機轉速下降，工作速度變慢，挖掘無力等。工作速度變慢：如果是使用多年的挖掘機，速度逐漸變慢，這屬于正常磨損所致。主要因素整機各部磨損造成發(fā)動機功率下降與液壓系統(tǒng)內泄，這樣就一系列故障都表現(xiàn)出來了，由于泄漏造成內部能量消耗，產生大量熱能，使整個系統(tǒng)迅速升溫，液壓油及發(fā)動機機油粘度下降，使整個系統(tǒng)產生高溫，表現(xiàn)為涼車稍快越熱越慢，這就需要全機大修，對磨損超限的零部件進行修復更換。如果是新挖機突然變慢，這就要先簡后繁，從以下幾方面檢查：先查電路保險絲是否斷路或短路;先導壓力是否正常;伺服控制閥-伺服活塞是否卡死;分配器合流故障等;排除了其它可能性，然后拆解液壓泵。貴州裕鑫工程機械有限公司是具有完善的施工隊及專業(yè)的維修隊伍。主營：挖掘機的整機租賃、土石方工程，等業(yè)務。常年對外出租，價格公道，誠實守信，合作共贏；租用方式靈活、包月、計時、按臺班均可。承接：大小土石方工程，歡迎咨詢洽談。

裕鑫工程機械分享，挖掘機維修之發(fā)動機。合理使用。（1）嚴防發(fā)動機啟動后立刻加速正常情況下，貴州挖掘機維修會有一定量的潤滑油存留在軸承中，可供發(fā)動機和怠速時潤滑用，但是，若發(fā)動機轉速超過1000r/min時，就需要有潤滑油流潤滑，發(fā)動機啟動后至少需要15~30s才能在潤滑系統(tǒng)中形成油壓和油流，如果在節(jié)氣門大開下啟動，2s內便可達到頂峰轉速，這就是說軸承將在十秒內處于無潤滑的狀態(tài)下，且以較高速度運轉，因此很容易引起軸承損傷。為此，應切記必須在節(jié)氣門處于怠速位置時才能啟動，即至少在30s內發(fā)動機轉速不允許超過1000r/min。如果發(fā)動機放置超過兩天，為了給啟動提供潤滑，可以搖轉發(fā)動機（切斷燃油）直至有油壓顯示后方可啟動。（2）盡量避免發(fā)動機在低速重載下長期工作發(fā)動機在低速重載工況下工作，軸承會處在邊界潤滑狀態(tài)，特別是當發(fā)動機轉速減低至振抖點時，由于受振波的作用金屬之間直接接觸的可能極大。為此應將低速重載工況限制在**小限度。貴州裕鑫工程機械有限公司是具有完善的施工隊及專業(yè)的維修隊伍。承接：大小土石方工程，歡迎咨詢洽談。
