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.
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.
1、 Reduce the impact of mechanical impurities
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.
2、 Reduce the impact of temperature
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.
3、 Reduce the impact of corrosion
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.
