挖掘机全车无力动作慢的解决方法

来源:http://www.ycgjglcl.com/ 日期:2022-05-09
  很多时候会遇到的挖掘机全车无力、动作慢的问题,而很多时候同一个故障现象,却可以有很多原因导致的。那么下面我们就来讲讲挖掘机全车无力动作慢的解决方法是怎样的。
  Most of the time, we will encounter the problem of weakness and slow movement of the excavator, and in many cases, the same fault phenomenon can be caused by many reasons. So let's talk about how to solve the problem that the whole excavator is weak and slow.
  我们要判断一下发动机是否带负荷。如果发动机感觉像空转没有出力的情况下直接可以排除掉发动机方面的因素。这个时候要确保挖掘机的先导一次压力是否在标准数值。
  We need to determine whether the engine is loaded. If the engine feels like idling without output can be directly eliminated engine factors. At this time to ensure that the first pressure of the excavator is in the standard value.
  检查每个动作输出的主油压力了。每款机子吨位的压力不一样的哈。详细参照主机厂数据。测量的时候建议按照厂家的要求,大油门,强力模式,液压油温度,水温都处于正常工作的标准温度是很合适的。
  Check the main oil pressure for each action output. Each machine tonnage pressure is not the same ha. Refer to OEM data for details. When measuring, it is recommended to follow the requirements of the manufacturer. Large throttle, strong force mode, hydraulic oil temperature and water temperature are all in the standard temperature of normal operation.
  主压力够的情况下,也就是发动机转速正常,我们就是考虑液压系统的流量问题了。流量小,所以导致动作慢,显得无力。但是压力够的话我们可以初步排除掉液压系统主油路内泄的问题。这个一般都是控制系统或者液压泵变量机构卡滞或者变量机构内泄导致的。
  The main pressure is enough, that is, the engine speed is normal, we are considering the hydraulic system flow problem. Flow is small, so lead to slow action, appear weak. But if the pressure is enough, we can initially rule out the problem of leakage in the main oil circuit of the hydraulic system. This is generally the control system or hydraulic pump variable mechanism stuck or variable mechanism internal leakage.
  如果反馈压力正常,那就是泵的变量机构有问题,这些都可以检查的。不过这个检查没有工具也不好着手。我们要做的就是电磁阀输出电压是否正常?电磁阀有无卡滞?主泵电磁阀与其相关的电路有问题也会导致发动机憋车掉速冒黑烟等现象哈。
  If the feedback pressure is normal, it is a problem with the variable mechanism of the pump, which can be checked. But it's hard to do without tools. What we need to do is whether the output voltage of the solenoid valve is normal? Is the solenoid valve stuck? The main pump solenoid valve and its related circuit problems will also lead to engine slow down black smoke and other phenomena.
  济南挖掘机租赁人员认为这个时候考虑的是液压系统内泄导致的动作慢,全车无力的现象。如果全车每个动作的压力都不够,我们要考虑的是共用的系统。比如主溢流阀,卸荷阀,液压泵泵胆平面。当然每种液压系统机型会有些区别的。
  Ji 'nan excavator leasing personnel think that at this time, they consider the slow action caused by internal leakage of the hydraulic system, and the phenomenon of weakness of the whole car. If the pressure is not enough for every movement in the car, we need to consider the shared system. Such as the main relief valve, unloading valve, hydraulic pump bladder plane. Of course, each hydraulic system model will have some differences.
  所以说虽然故障是一样的,但原因却不同,因此要具体问题,具体分析。如果您想知道更多问题的话,就来网站www.ycgjglcl.com进行咨询吧。
  So although the fault is the same, but the reasons are different, so to specific problems, specific analysis. If you want to know more, please visit www.ycgjglcl.com.
