长臂挖掘机的常见故障问题

日期:2018-04-26   来源:/
随着科技的进步,现今伸缩臂挖机租赁一般都采用了机—电—液一体化控制模式,我们在排除一些故障时,解决的多是发动机—液压泵—分配阀—外部负荷的匹配问题。
With the progress of science and technology, the machine - electro - hydraulic integrated control mode is generally adopted in the tenancy of the telescopic boom excavator. When we eliminate some failures, we solve the matching problem of the engine hydraulic pump distribution valve and the external load.
1、发动机转速下降:
1, engine speed decline:
首先要测试发动机本身输出功率,如果发动机输出功率大大低于额定功率,如是在施工现场判断要从最简单的方法入手,首先看燃油滤芯是否堵塞,燃油路中是否有漏气的地方,燃油泵中的柱塞,喷油头,出油阀是否严重磨损,空气滤芯进气是否通畅,带涡轮增压器的发动机,涡轮增压器是否损坏,发动机是否快速高温,机油粘度下降,造成缸壁封闭不严压缩比下降,是否缸套组件磨损造成缸内严重串气,发动机气门封闭不严等,这些都是严重影响发动机功率的因素。
First of all, to test the output power of the engine itself, if the engine output power is greatly lower than the rated power, for example, in the construction site to judge from the simplest method, first see whether the fuel filter core is blocked, the fuel road has leakage of gas, the plunger in the fuel pump, the injection head, and the serious wear and tear of the oil outlet valve. If the air filter is unobstructed, the engine of the turbocharger, the turbocharger is damaged, whether the engine is fast and high temperature, the viscosity of the engine oil decreases, the cylinder wall is closed and the compression ratio decreases, whether the cylinder sleeve components are worn out in the cylinder and the engine gas door is closed, these are serious shadows. The power factor of the engine.
2、工作速度变慢:
2, the speed of work is slow:
主要因素整机各部磨损造成发动机功率下降与液压系统内泄,这样就一系列故障都表现出来了,由于泄漏造成内部能量消耗,产生大量热能,使整个系统迅速升温,液压油及发动机机油粘度下降,使整个系统产生高温,表现为凉车稍快越热越慢,这就需要全机大修,对磨损超限的零部件进行修复更换。
The main factor is that the wear of all parts of the whole machine causes the power decline of the engine and the leakage of the hydraulic system. In this way, a series of failures are shown. As the leakage causes internal energy consumption, a large amount of heat energy is produced, the whole system is heated up rapidly, the viscosity of the hydraulic oil and engine oil drops, and the whole system produces high temperature. The cooler is slower and hotter and slower, which requires full machine overhaul and repair and replacement of parts with excessive wear and tear.
