长臂挖掘机高温低温都易造成机械故障!
发布时间:2020-12-08 15:02:44 浏览:[97]次

 如今,小型挖掘机凭借其灵活性、便携性和在狭小空间工作的能力,占据了挖掘机市场的一角。但这是否意味着人们不再需要性能可靠的大型挖掘机来进行大规模作业?答案当然是否定的!与大型挖掘机相比,小型挖掘机的容量远远小于大型挖掘机,挖掘力也远小于大型挖掘机。大型挖掘机具有大容量、率和快速性的优点,可以大大提高生产率。他们是作为技术工程机械人员不可忽视的细节。今天,小编向您讲述大型挖掘机的机械故障。

  Today, small excavators with their flexibility, portability and the ability to work in a narrow space, occupy a corner of the excavator market. But does this mean that people no longer need reliable large excavators for large-scale and efficient operations? The answer, of course, is no! Compared with large excavators, the capacity of small excavators is far less than that of large excavators, and the digging force is also far less than that of large excavators. Large excavator has the advantages of large capacity, high efficiency and rapidity, which can greatly improve the productivity. They are the details that can not be ignored as technical engineering machinery personnel. Today, extended arm excavator rental to tell you about the mechanical failure of large excavators.

  在操作过程中,不可避免地会遇到这样或那样的故障问题,大型挖掘机也不例外。让我们跟随边肖的脚步,看看如何减少或避免大型挖掘机在运行过程中的故障问题。

  In the process of operation, it is inevitable to encounter this or that kind of fault problems, large excavators are no exception. Let's follow Bian Xiao's steps to see how to reduce or avoid the failure of large excavators during operation.

  一,减少机械杂质造成的影响

  1、 Reduce the impact of mechanical impurities

  挖掘机的机械杂质一般是指使用过程中由粉尘、土壤等非金属物质产生的金属碎屑和磨损产物。这些杂质一旦进入大型挖掘机的机械中,会对机械零件造成很大的损坏。它不仅会阻碍机械零件的运动,加速零件的磨损,摩擦零件的表面,还会破坏润滑油膜,使零件温度升高,润滑油变质。

  Mechanical impurities of excavators generally refer to metal debris and wear products produced by non-metallic materials such as dust, soil, etc. Once these impurities enter the machinery of large excavators, they will cause great damage to mechanical parts. It will not only hinder the movement of mechanical parts, accelerate the wear of parts, rub the surface of parts, but also damage the lubricating oil film, so that the temperature of parts increases and the lubricating oil deteriorates.

  二,减少温度造成的影响

  2、 Reduce the impact of temperature

  在使用大型挖掘机机械的过程中,防止其在低温下超负荷运行,保证低速预热阶段的正常运行,并使挖掘机在进行下一步操作前达到恒温。记住不要因为明显的问题还没有出现就忽视它们。其次,应防止挖掘机在高温下运行。在大型挖掘机运行期间,应始终观察每个温度计的温度值。一旦发现任何异常,应立即停机检查,并在进行下一步操作前排除故障。

  In the process of using large excavator machinery, it is necessary to prevent overload operation at low temperature, ensure the normal operation of low-speed preheating stage, and make the excavator reach constant temperature before the next operation. Remember not to ignore obvious problems just because they don't appear. Secondly, the excavator should be prevented from running under high temperature. During the operation of large excavators, the temperature value of each thermometer should be observed at all times. Once any abnormality is found, stop the machine immediately for inspection and remove the fault before proceeding to the next step.

  三,减少腐蚀造成的影响

  3、 Reduce the impact of corrosion

  什么是腐蚀?指金属表面因与周围介质的化学或电化学相互作用而受损的现象。这种腐蚀不仅会导致大型挖掘机的机械表面不能正常工作,还会对机器内部零件造成严重损坏。在使用中,挖掘机管理人员和操作人员应根据天气预报和空气质量采取有效的防护措施。从而有效降低化学腐蚀对大型挖掘机机械设备的影响。其中,我们应该强调的是防止雨水侵蚀建筑机械。

  What is corrosion? It refers to the phenomenon that metal surface is damaged by chemical or electrochemical interaction with surrounding media. This kind of corrosion will not only cause the mechanical surface of large excavator not work normally, but also cause serious damage to the internal parts of the machine. In use, excavator managers and operators should take effective protective measures according to weather forecast and air quality. So as to effectively reduce the impact of chemical corrosion on the mechanical equipment of large excavators. Among them, we should emphasize the prevention of rain erosion of construction machinery.
