挖掘机“憋车”通常是指挖掘作业时工作无力,柴油机转速持续下降,严重时甚至造成柴油机熄火。挖掘机出现“憋车”现象,根本原因是柴油机输出的功率小于液压系统所产生的载荷。挖掘机“憋车”时,大大降低了其挖掘效率,导致其无法进行正常作业。本文对挖掘机“憋车”的原因进行分析,并提出排查方法。 Excavator “Cushion ” usually refers to the mining work was weak, the diesel engine speed continued to decline, and even cause serious diesel engine flameout. Excavator “ The fundamental reason is that the diesel engine output power is less than the hydraulic system generated load. Excavator ”Caster “, greatly reducing its mining efficiency, resulting in its normal operation can not be. This article analyzes the causes of the excavator ”Cushioning " and puts forward the method of investigation.
