挖掘机大臂速度慢
Slow speed of excavator arm
1.查看先导压力是否在40KG左右,大臂二次先导压力是否正常。
1. Check whether the pilot pressure is around 40KG and whether the secondary pilot pressure of the arm is normal.
2.大臂压力传感器是否损坏或许线路毛病。
2. Whether the arm pressure sensor is damaged or the line is faulty.
3.大臂合流阀是否卡死,磨损内泄导致。
3. Whether the upper arm confluence valve is stuck or not, which is caused by wear and internal leakage.
4.查看大臂保持阀是否有卡死磨损的现象。
4. Check whether the arm retaining valve is stuck and worn.
挖掘机大臂没有力
Excavator arm is weak
1.查看大臂溢流阀是否有磨损或许卡泄的现象导致压力不足。
1. Check whether the arm relief valve is worn or jammed, resulting in insufficient pressure.
2.大臂阀杆是否有磨损导致的没力。
2. Whether the arm stem is weak due to wear and tear.
3.大臂吸油阀(负载单向阀)是否有卡涩导致的毛病。
3. Whether the arm oil suction valve (load one-way valve) is stuck or not.
挖掘机大臂掉臂现象
Arm drop of excavator arm
1.查看大臂保持阀阀芯是否存在磨损现象。
1. Check whether there is wear on the valve core of the arm retaining valve.
2.大臂阀杆磨损严峻。
2. The wear of the arm stem is severe.
3.大臂油缸油封老化损坏造成泄压掉臂现象。
3. The aging damage of the oil seal of the upper arm cylinder results in the phenomenon of pressure relief arm drop.
注意事项
Matters needing attention
以上几种大臂毛病现象,基本上涵盖了日常施工过程中挖掘机极易呈现的问题,当毛病呈现时,我们首先测量相应部件的压力是否在正常范围内,查看出问题后拆下相应部件进行简单整理查看。
Above several kinds of arm defects basically cover the problems that excavators are easy to present in the daily construction process. When the defects occur, we first measure whether the pressure of the corresponding components is within the normal range, and after checking out the problems, we take down the corresponding components for simple sorting and inspection.
有一点需求大家记住,简单的拆卸处理后看似部件没有任何问题了,但安装后仍然呈现毛病,这种状况就必须修理或许替换才能够彻底解决。
One thing you need to remember is that after simple disassembly, there seems to be no problem with the parts, but there are still problems after installation. This situation must be repaired or replaced before it can be completely solved.
挖掘机大臂毛病总结
Summary of the Troubles of Excavator Arm
大臂的重要性,在这里就不在赘述了,无论是作为机手还是老板,都有一个共同的想法,那就是挖掘机别呈现毛病问题,顺畅施工结束。
The importance of the big arm is no longer mentioned here. Whether as a pilot or a boss, there is a common idea that the excavator is not showing problems and the construction is finished smoothly.
