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挖机加长臂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, such as the washing machine that broke down soon after we bought it, the TV that went on strike soon after we bought it, etc; So what are the problems that construction machinery professionals often encounter? That is, the extended arm of their operating tool, the excavator, always has some small faults, and the work is not smooth.
对于挖机机主而言，挖机加长臂的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。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。
For the excavator owner, the creeping phenomenon of the oil cylinder rod of the excavator's extended arm is a common small fault and also a problem. The creeping phenomenon of the excavator's 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. If you want to avoid the pit, you must understand the cause of the pit. Next, Huitong Heavy Industries will talk about what causes it.
有可能是油缸进入空气导致的；可以通过除掉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。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 be caused by air entering the oil cylinder; It can be checked by removing the possibility of air intake from 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. It may also be caused by poor accuracy of the hydraulic cylinder; You can check whether the installation of the hydraulic cylinder is strictly in accordance with the standards, such as some size standards and installation materials. In addition, this problem may also occur if the hydraulic cylinder end cap seal is pressed too tight or too loose.
如果你的挖机加长臂出现关闭了挖机后，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，排查这些原因去这个问题。避开这个烦恼，让挖机加长臂工作更顺畅。
If the oil cylinder still moves after the excavator is shut down, that is, the oil cylinder rod crawls, you can check the causes to solve the problem. Avoid this trouble and make the excavator's extended arm work more smoothly.
