如何正确应对挖掘机转速下降

日期:2018-03-23   来源:/
我们知道建筑工程开始都是要用到挖掘机,使用挖掘机要掌握正确有效的挖掘方法,同时对于挖掘机的突发故障我们也应该了解,比如挖掘机转速下降就是一个比较常见的故障,那么当我们遇到这个情况的时应该如何进行处理呢?

We know that the construction start is to use the long arm of the excavator, the use of long arm excavator to master the mining method is correct and effective, at the same time for the sudden failure of long arm excavator we should also know, such as the long arm excavator speed down is a common fault, so when we encounter this situation should be how to deal with it?
当挖掘机的发动机发生转速下降时,首先必须对发动机的机身所输出的功率进行测试,经测试,如果发现发动机机身的输出功率要比原来输出功率要小,那么导致故障发生的原因可能是燃油的品质太差、气门的间隙不合格、燃油的压力太低、发动机的某个缸没有进行工作、喷油设置的时间出现错误、进气系统发生漏气现象、燃油量的调定值发生错误、涡轮器中产生的积碳现象严重以及对制动器的操作出现了问题等等。


When the engine speed decreases when the excavator, must first output power of the engine body of the test, after the test, if it is found that the output power of the engine body is smaller than the original output power, then lead to failure may be due to fuel quality is poor, the valve clearance unqualified, fuel pressure too low, the engine of a cylinder without work, injection set time errors, the intake system leakage phenomenon, fuel quantity setting error, the turbine produced in the serious phenomenon of carbon deposition and the brake operation problems etc..
在挖掘机租赁运行时,如果出现了运转速度和运行荷载之间所呈现的是反比例关系,那么也就是说液压泵的流量和液压泵输出压力相乘,然后得出的结果是定值,就可以确定液压泵的输出功率是恒定的。
In the long arm excavator leasing operation, if there is between the running speed and running load is inversely proportional, that is to say the flow and the hydraulic pump output pressure by hydraulic pump, and the result is a fixed value, you can determine the output power of the hydraulic pump rate is constant.
