改装挖掘机加长臂可能出现哪些故障

日期:2019-04-26   来源:
  目前,随着城市化建设的不断发展,需要将一些旧楼拆除,而在这个过程中,就需要运用到挖掘机加长臂这类的机械设备,才能保证施工的顺利进行。挖掘机加长臂是在普通挖掘机的基础上进行改装的,需要加长挖掘机机械手臂的挖掘长度。
  At present, with the continuous development of urbanization construction, some old buildings need to be demolished, and in this process, mechanical equipment such as excavator elongation arm need to be used to ensure the smooth progress of construction. The lengthening arm of excavator is refitted on the basis of ordinary excavator. It is necessary to lengthen the excavation length of excavator's mechanical arm.
  但是如果挖掘机加长臂改装不当就会发生故障。今天就为大家讲解下挖掘机加长臂改装不当容易出现的一些故障。希望在生活中对您有一定的帮助。
  But if the lengthening arm of excavator is improperly refitted, it will break down. Today, I'll explain some faults that are easy to occur when the lengthening arm of excavator is improperly refitted. I hope it will help you in your life.
  挖掘机加长臂改装中有哪些常见故障?
  What are the common faults in the refitting of the excavator's elongated arm?
  1、挖机右行走和铲斗无动作,动臂和斗杆动作慢挖掘机加长臂改造后出现此故障通常是在密封控制总阀之后将组阀的阀和堵头位置装反造成的,一般情况下,只要将阀和堵头的位置交换过来既可以恢复正常。
  1. The excavator moves right and the bucket does not move. The failure of the moving arm and the long arm of the bucket pole slow-moving excavator is usually caused by installing the valve and plug position of the group valve back after the sealing control main valve. Generally, as long as the position of the valve and the plug is exchanged, it can return to normal.
  2、全车慢且无力
  2. The whole car is slow and weak.
  如果挖掘机加长臂改装完成在正常工作一段时间之后出现这种故障,首先测试先导压力,如果压力很低,有可能是先导泵输入轴的骨架油封在安装不当或压力过高而被挤出,通常是由于先导泵油封方向装反导致压力油泄出,所以应该更换损坏的部件,并正确安装先导泵油封。
  If this kind of fault occurs after the long arm of excavator has been refitted for a certain period of time after normal operation, the pilot pressure should be tested first. If the pressure is very low, it may be that the skeleton oil seal of the input shaft of the pilot pump is extruded due to improper installation or excessive pressure. Usually, the pressure oil leaks out due to the reverse direction of the oil seal of the pilot pump. Therefore, the damaged parts should be replaced and installed correctly first. Guide pump oil seal.
  3、发动机起动后斗杆油缸的活塞杆自动缩回,其它动作正常改装成挖掘机加长臂后出现这个故障,通常故障出在控制阀或斗杆油缸,本着先易后难的原则拆检控制阀杆,如果阀杆卡在活塞杆缩回位置,则用橡胶锤和铜棒震动后取出阀杆。如果见有闪亮铁末,联系斗杆下沉较快,那么可以判断故障根源为加长臂斗杆缸筒拉伤,拆检斗杆油缸进行处理即可。

  3. The piston rod of the bucket rod cylinder automatically retracts after the engine starts. The other normal actions are refitted to the excavator's elongated arm, which usually results from the failure of the control valve or the bucket rod cylinder. The control rod is disassembled and inspected according to the principle of easy first and difficult later. If the valve rod is stuck in the retracted position of the piston rod, the valve rod is vibrated with a rubber hammer and a copper rod and then removed. If there is shining iron end and the bucket rod sinks quickly, it can be judged that the fault originates from the pull of the cylinder barrel of the extended arm bucket rod, and the bucket rod cylinder can be disassembled and inspected for treatment.

  以上讲解的就是改装挖掘机加长臂之后比较容易出现的故障现象,通过这篇文章,我们知道了大部分的故障都是改造时安装不当造成的,所以,要想获得稳定性好的挖掘机加长臂,那么就要有专业技术人员来改造,确保每一个部位都能正确的安装到挖掘机中去。
  The above explanation is that it is easy to break down after refitting the excavator's elongated arm. Through this article, we know that most of the breakdowns are caused by improper installation during the retrofit. Therefore, in order to obtain a stable excavator's elongated arm, it is necessary to have professional and technical personnel to retrofit it to ensure that every part of the excavator can be installed correctly.
