怎么应对长臂挖掘机转速下降?

  我们知道开始的开始建设项目用于长臂挖掘机,使用延长臂挖掘机掌握正确的和有效的采矿方法,并延长臂挖掘机突然故障我们也或多或少应该知道一些,比如延长臂挖掘机速度下降是一种常见的错误,当我们见面,我们应该如何处理这种情况?
  We know that the starting construction project is for long arm excavators, using extended arm excavators to master the correct and effective mining methods, and the sudden failure of extended arm excavators. We should know more or less that, for example, the speed decline of extended arm excavators is a common mistake. When we meet, how should we deal with it? This situation?
  当挖掘机发动机转速下降时,您必须首先测试发动机的输出功率,在测试之后,如果发现发动机机体的输出功率小于原来的输出功率,所以失败的原因可能是低质量的燃料,气门间隙不合格,燃油压力过低,发动机的缸不工作,注射时间误差,进气系统泄漏发生时,燃料的数量设置错误发生,涡轮以及积碳现象严重,给制动器的运行带来了问题等。此时,如果发现发动机输出功率正常,则检查液压泵流量是否与发动机输出功率不匹配。
  When the speed of excavator engine decreases, you must first test the output power of the engine. After testing, if the output power of the engine block is found to be less than the original output power, the reasons for failure may be low-quality fuel, unqualified valve clearance, low fuel pressure, engine cylinder not working, injection time error. Poor, when the air intake system leakage occurs, the number of fuel setting errors occur, and the phenomenon of turbine and carbon deposition is serious, which brings problems to the operation of the brake and so on. At this time, if the engine output power is normal, check whether the flow rate of the hydraulic pump does not match the engine output power.

  加长臂挖掘机租赁操作的,如果有一个逆运行速度和运行负荷之间的关系,那么也就是说,液压泵流量和液压泵的输出压力倍增,而结果是一个恒定值,它可以确定液压泵输出功率是恒定的。如果在控制液压泵的系统中发现故障,无法对发动机、液压泵和配水阀进行优化匹配,使挖掘机无法正常工作。因此,首先要检查电气系统,然后是液压系统,最后是长臂挖掘机系统和传动装置。
  If there is a relationship between the reverse speed and the operating load of the leasing operation of the extended arm excavator, that is to say, the flow rate of the hydraulic pump and the output pressure of the hydraulic pump multiply, and the result is a constant value, which can determine that the output power of the hydraulic pump is constant. If faults are found in the control system of the hydraulic pump, it is impossible to optimize the matching of the engine, the hydraulic pump and the water distribution valve, which makes the excavator unable to work properly. Therefore, first of all, we should check the electrical system, then the hydraulic system, and finally the long arm excavator system and transmission device.
