挖掘机伸缩臂掉臂与哪些原因有关?

日期:2020-08-21   来源:
1.挖掘机的液压油缸出现故障,尤其是油缸油封损坏或老化,造成油封内漏引起的。
1. The hydraulic cylinder of the excavator is in trouble, especially the oil seal of the oil cylinder is damaged or aged, which causes the oil seal to leak inside.
2.当挖掘机伸缩臂安全溢流阀油封破损时,造成一定的泄漏,也会导致掉臂现象。
2. When the oil seal of the safety relief valve of the telescopic boom of the excavator is damaged, a certain amount of leakage will be caused, and the arm will fall off.
3.分配阀阀孔阻塞、阀芯磨损、阀芯间隙过大、分配阀主安全阀磨损损坏,引起的挖掘机臂掉臂。
3. The excavator arm fell off due to blocking of distribution valve hole, wear of valve core, excessive clearance of valve core and wear and damage of main safety valve of distribution valve.
4.分配泵密封不良造成的,也称之为“卸油",这时需要将分配泵的密封圈更换。
4. The poor sealing of the distribution pump is also called "oil unloading". At this time, the sealing ring of the distribution pump needs to be replaced.
5.液压泵比例电磁阀接头接触不良,也会引起挖掘机伸缩臂掉臂现象。
5. Poor contact of the hydraulic pump proportional solenoid valve joint will also cause the excavator telescopic arm to fall off.
6.分配泵密封不良造成的,也称之为“卸油",这时需要将分配泵的密封圈更换。
6. The poor sealing of the distribution pump is also called "oil unloading". At this time, the sealing ring of the distribution pump needs to be replaced.
7.严重掉臂(油温45℃左右,5分钟斗齿下降超过95mm),更有可能是主阀被卡导致的。
7. Serious arm drop (the oil temperature is about 45 ℃, the bucket teeth drop more than 95mm in 5 minutes), which is most likely caused by the main valve being stuck.

优势特点:
Advantages and features:
、有效作业距离大,作业高度高。通过挖掘机伸缩臂结构可以达到目的较远的距离,通过臂的变幅可以达到较高的作业高度,这是传统挖掘机不能比拟的。
First, the effective working distance is large and the working height is high. Through the telescopic arm structure of the excavator, a longer distance can be achieved, and a higher working height can be achieved through the luffing of the arm, which is incomparable with the traditional excavator.
第二、能越过部分障碍直接装卸货物。采用挖掘机伸缩臂装置可以跨越小沟,台阶,门窗孔进行装卸作业;由于具有负的变幅角度,也可对停机面的沟渠进行了清沟或修破,平整等作业,因而更加适合在野外条件下使用。
Second, it can cross some obstacles to load and unload goods directly. The excavator telescopic arm device can cross small ditches, steps, doors and windows for loading and unloading operations; because of the negative amplitude angle, it can also clear, repair and level the ditch on the parking surface, so it is more suitable for use in the field conditions.
第三、具有较好的作业安全性能。伸缩臂挖掘机具有负载伸缩功能,在不平路面进行堆高作业时,可在远离堆垛点的位置停车,打开稳定支腿,运用伸缩,变幅动作完成对货物的装卸作业;在炼钢车间进行炉膛的清理拆卸作业也很方便。
Third, it has good safety performance. Telescopic boom excavator has the function of load expansion and extension. When stacking on uneven road surface, it can stop at a position far away from the stacking point, open the stable legs, and complete the loading and unloading of goods by using the telescopic and luffing actions; it is also convenient to clean and dismantle the furnace in the steel-making workshop.
