挖掘机使用出现一些常见小故障要会修理

日期:2022-07-15   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挖机加长臂老是出现一些小故障,工作起来不顺畅。
In daily life, we often encounter some trivial troubles, such as the washing machine that broke down not long after we bought it, the TV that went on strike not long after we bought it, and so on; So what are the problems that construction machinery professionals often encounter? That is, their working tool, the lengthening arm of the excavator, always has some small faults, which makes it difficult to 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。想要避开这个坑,就要了解这个坑产生的原因。
For excavator owners, crawling of excavator oil cylinder rod is a common minor fault, and they also feel annoyed. Crawling of excavator oil cylinder means that after the excavator is closed, the oil cylinder still moves. If you can avoid the pit where the excavator cylinder rod crawls, you won't have so much trouble. If you want to avoid this pit, you need to understand the cause of this pit.
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. You can eliminate the possibility of air inlet of the hydraulic pump to troubleshoot. Run the hydraulic cylinder for many times to exhaust. When the leaked oil becomes clear, it indicates that there is no air.
加长臂挖掘机
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。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,让挖机加长臂工作更顺畅。
It may also be caused by the poor accuracy of the hydraulic cylinder. You can check whether the installation of the hydraulic cylinder is in strict accordance with the standards, such as some size standards and installation materials. In addition, the hydraulic cylinder end cover seal pressed too tight or too loose will also lead to this problem. If the oil cylinder of your lengthening arm excavator still moves after the excavator is shut down, that is, the oil cylinder rod crawls, you can first self check and investigate these reasons to solve this problem. Avoid this trouble and make the excavator lengthening arm work more smoothly.
此外,一边履带只能行进不能撤退。是何原因?是行走马达中的过载溢流阀芯被卡死所造成的。行走马达为维护体系的安全,在体系中设置了2个过载溢流阀,假如其中有一个过载溢流阀阀芯卡死在溢流位置时,体系压力就丢失了。
In addition, one track can only travel and cannot retreat. Why? It is caused by the overload overflow valve element in the travel motor being stuck. In order to maintain the safety of the system, the travel motor is equipped with two overload relief valves in the system. If one of the overload relief valves is stuck in the overflow position, the system pressure will be lost.
研磨齿轮端面要注意些啥?齿轮泵齿轮磨损后,要用精度高的磨床进行磨削,要找责任心强的师傅操作。比如,磨床工作台要肯定洁净,不允许平台上有尘土。由于工作台稍有不洁净,都会使磨出的平面与轴承孔的笔直线发作偏移。
What should we pay attention to when grinding the gear end face? After the gear of the gear pump is worn, it is necessary to use a high-precision grinder for grinding, and it is necessary to find a master with a strong sense of responsibility to operate. For example, the grinding machine workbench must be clean and no dust is allowed on the platform. Because the workbench is slightly unclean, the ground plane will deviate from the pen line of the bearing hole.
