  油泵的维修方法
  Maintenance Method of Oil Pump
  1部件及外露活塞杆上的沉积物可防止污物进入油缸,损坏活塞、气缸或密封件。
  1. Sediments on components and exposed piston rods can prevent dirt from entering the cylinder and damaging the piston, cylinder or seal.
  2经常检查每根螺纹和螺栓的连接件,如有松动应立即拧紧。
  Check the connecting parts of each thread and bolt regularly. If loose, tighten them immediately.
  3经常润滑连杆,以防止在无油状态下生锈或异常磨损。
  Frequently lubricate connecting rods to prevent rusting or abnormal wear in oil-free condition.

  4定期更换液压油滤芯和液压油回油,保证油品清洁,延长油缸使用寿命。
  4 Regular replacement of hydraulic oil filter element and hydraulic oil return to ensure oil cleanliness and prolong the service life of cylinders.
  5工作装置运行前,应将油缸内的空气排尽,并在带负荷运行前进行5冲程的全张缩试运转。
  Before the operation of the working device, the air in the cylinder should be exhausted and the full stretch test run of 5 strokes should be carried out before the operation with load.
  6注意液压油的温度,如油温过高会损坏或变形密封件。永久变形,甚至完全破坏。
  6. Pay attention to the temperature of hydraulic oil. If the oil temperature is too high, the seal will be damaged or deformed. Permanent deformation, or even complete destruction.

  7年每次完成工作后,挖掘机应停在平地上,活塞杆应完全恢复,因此圆柱体的大空腔,确保所有的液压油缸返回到油箱,以确保缸不承受压力。
  After 7 years of work, the excavator should stop on the flat ground and the piston rod should be completely restored. Therefore, the large cylindrical cavity ensures that all hydraulic cylinders return to the tank to ensure that the cylinder does not withstand pressure.

  油缸保养
  Cylinder Maintenance
  这台新买的挖掘机工作量不大,为什么老是坏,你知道吗?挖掘机在日常工作中,由于长期操作不当而积累了故障。作为一名挖掘机司机,你有没有犯过以下的错误?
  This newly bought excavator is not very workload, why is it always bad, you know? In daily work, the excavator accumulated faults due to long-term improper operation. As a excavator driver, have you ever made the following mistakes?
  1工作装置在完全恢复前运行
  1. Operation of the working device before full recovery
  当挖掘机的工作装置不完全恢复时,挖掘斗容易撞击岩石,气缸活塞杆产生较大载荷,导致气缸内部损坏,销轴周围开裂。
  When the working device of excavator is not fully restored, the excavator bucket is prone to impact rock, and the cylinder piston rod produces a larger load, which results in damage to the cylinder and cracking around the pin shaft.
  2缸体拉杆伸缩至开挖极限
  2. Extension of cylinder block tie rod to excavation limit
  液压缸的挖掘机是伸缩式到末端位置进行开挖作业的。在这种情况下,工作缸与齿条会产生较大的载荷,冲击斗齿,冲击每一个轴销,可能会造成缸内损坏,还会影响其他液压元件。
  Hydraulic cylinder excavator is telescopic to the end of the excavation operation. In this case, the cylinder and rack will produce a larger load, impact bucket teeth, impact each pin, may cause damage in the cylinder, but also affect other hydraulic components.
  3挖掘机启动时没有站稳
  3 Excavator does not stand steadily when starting
  这是我们经常遇到的一种常见情况,路面不平整(如碎石路面),在挖掘机没有停止工作的情况下,长时间的向下行驶会造成框架下受力不均,对框架造成损坏。这种情况,最好是垫一些土在下面,使地面平整,这样再操作。
  This is a common situation that we often encounter. The uneven road surface (such as gravel road surface) will cause uneven force under the frame and damage the frame if the excavator does not stop working for a long time. In this case, it is better to lay some soil under it to make the ground flat, so that it can be operated again.
  4破碎锤频率过高
  4. The frequency of crushing hammer is too high
  活塞杆长时间断裂,高频振动,应力过大,容易引起活塞杆弯曲断裂。
  Piston rod ruptures for a long time, high frequency vibration and excessive stress easily cause bending fracture of piston rod.
  为了加长臂挖掘机能工作很长时间,平时都要做这些小事情,挖掘机是挖土机兄弟的工具赚钱,也是战友,一起风雨无阻,还能保护机器。想要了解更多内容,欢迎访问网站:http://www.rbaras.com
  In order to lengthen the arm of the excavator to work for a long time, usually to do these small things, excavator is the excavator brother's tool to make money, but also comrades-in-arms, together rain and wind, but also to protect the machine.
