举例加长臂挖掘机使用常见小故障

日期:2022-08-17   来源:http://www.dybocheng.com
在日常生活中我们经常遇到一些琐事烦恼,比如我们买了洗衣机没多久就坏了,买了没多久就罢工的电视机等等;那么对于工程机械行内人来说,他们经常碰到的问题是什么呢?那就是他们的作业工具加长臂挖掘机老是出现一些小故障,工作起来不顺畅。
In our daily life, we often encounter some trivial troubles. For example, we bought a washing machine that broke down not long ago, and bought a TV that went on strike not long ago; So what are the problems that people in the construction machinery industry often encounter? That is, their working tool, the extended arm excavator, always has some minor faults and does not work smoothly.
对于挖机机主而言,挖机油缸杆出现爬行现象是他们常见的小故障,也是感到比较烦恼的,挖机油缸出现爬行指关闭了挖机后,油缸还出现移动的情况。如果能够避开这个挖机油缸杆出现爬行现象的坑,就不会有这么多烦恼了。
For the excavator owner, the creeping phenomenon of the excavator oil cylinder rod is a common small fault, and it is also troublesome. The creeping phenomenon of the excavator oil cylinder means that the oil cylinder still moves after the excavator is closed. If we can avoid the pit where the oil cylinder rod of the excavator crawls, we won't have so much trouble.
想要避开这个坑,就要了解这个坑产生的原因。汇通重工接下来就来说说是什么原因导致的。
If you want to avoid this pit, you must understand the cause of this pit. Next, Huitong heavy industry will talk about what causes it.
有可能是油缸进入空气导致的;可以通过消除液压泵进气的可能来排查,将液压缸运转多次来进行排气,当漏出的油变为清亮后,就表明没有空气了。
It may be caused by air entering the oil cylinder; It can be checked by eliminating the possibility of air intake of the hydraulic pump. The hydraulic cylinder can be operated for several times to exhaust. When the leaked oil becomes clear, it indicates that there is no air.
也有可能是液压缸存在精度差导致的;可以检查液压缸的安装是否严格按照标准来的,像一些尺寸标准和安装的材料等。另外,液压缸端盖密封压得太紧或太松也会导致出现此种问题。
It may also be caused by poor accuracy of the hydraulic cylinder; You can check whether the hydraulic cylinder is installed in strict accordance with the standards, such as some size standards and installation materials. In addition, the sealing of the end cover of the hydraulic cylinder is too tight or too loose, which may also lead to this problem.
加长臂挖掘机
如果你的加长臂挖掘机出现关闭了挖机后,油缸还出现移动的情况,也就是油缸杆爬行现象,可以先自检,排查这些原因去解决这个问题。避开这个烦恼,让加长臂挖掘机工作更顺畅。
If the oil cylinder of your extended boom excavator still moves after the excavator is shut down, that is, the oil cylinder rod crawls, you can first conduct self inspection and find out these reasons to solve the problem. Avoid this trouble and make the work of the extended arm excavator more smooth.
此外改装成挖掘机加长臂后,发动机起动后斗杆油缸的活塞杆自动缩回,其它动作正常。经检查,一其余动作正常;二提起动臂后斗杆下沉较快。交换斗杆先导管后故障依旧,说明故障在控制阀或斗杆油缸,本着先易后难的原则。
In addition, after being modified into an excavator lengthening arm, the piston rod of the stick cylinder automatically retracts after the engine is started, and other actions are normal. After inspection, the other actions of the first one are normal; Second, after lifting the boom, the stick sinks quickly. The failure still exists after the pipe is replaced for the stick. It means that the failure is in the control valve or the stick cylinder. The principle of "easy first and difficult later" is followed.
拆检控制阀杆,发现阀杆卡在活塞杆缩回位置,用橡胶螂头和铜棒震动后取出阀杆。可见有闪亮铁末,联系斗杆下沉较快。判断故障根源为加长臂斗杆缸筒拉伤,拆检斗杆油缸后证实。
The control valve rod was disassembled and inspected. It was found that the valve rod was stuck at the retracted position of the piston rod. The valve rod was taken out after being vibrated with a rubber cockroach head and a copper rod. It can be seen that there is shiny iron dust, which makes the bucket stick sink faster. It is determined that the root cause of the fault is the stretching of the boom cylinder. It is confirmed after the boom cylinder is disassembled and inspected.
