The service life of construction machinery has always been a topic worthy of attention in the industry, especially for construction machinery such as high-altitude lifting platforms, excavators, and jib cranes. The service life is worth paying attention to. Let’s share with you below. How to extend the working life of these machines.

 

1. Try to reduce the influence of harmful factors

 

To achieve this, it is necessary to reduce the influence of continuing impurities. Mechanical impurities generally refer to non-metallic materials such as dust, soil, and some metal scraps and wear products generated by the self-lifting of construction machinery during use. Once these impurities enter the machine and reach between the matching surfaces of the machine, the harm is great; secondly, to reduce various corrosive effects, the phenomenon of damage caused by chemical or electrochemical reactions between the metal surface and the surrounding medium is called Corrosion Raymond Mill. This kind of corrosion will not only affect the normal operation of the mechanical exterior equipment, but also corrode the internal parts of the machine; reduce the influence of temperature. During work, the temperature of each part has its own normal range. For example, the temperature of the general cooling water is 80~90℃, and the temperature of the hydraulic oil of the hydraulic transmission system is 30~60℃. Lower or exceed this range will accelerate the wear of the parts, cause the deterioration of the lubricating oil, and cause the change of material properties.

 

2. Ensure normal working load

 

The size and nature of the working load of construction machinery have an important influence on the loss process of machinery. Generally speaking, the wear of parts increases in proportion to the increase in load. When the load on the part is higher than the average design load, its wear will increase. In addition, when other conditions are the same, stable load has less wear than dynamic load, fewer failures, and lower life.

 

3. Ensure reasonable lubrication of machinery

 

The wear of the working surface of the part, the corrosion of the surface of the part and the aging of the material are the three main failure modes of mechanical parts under normal use conditions, and the failure caused by the wear of the working surface of the part accounts for the largest proportion of the price of the stone crusher. In other words, mechanical wear is one of the main reasons for its various parts to reach the limit of technical state.

 

4. Take correct technical measures and organizational management measures

 

With the development of material science and design and manufacturing technology, many new technologies, new materials, and new structures have been adopted in construction machinery, requiring more scientific and complete mechanical technical support and management. For this reason, as the organization and management personnel and operators of construction machinery, one must pay attention to ensuring that the machinery is protected from damage, deformation, and corrosion during transportation and storage. Second, we must strictly implement the daily maintenance of the machinery to keep the machinery in a good technical condition.

 

5. Timely maintenance

 

Various jobs will inevitably occur during the use of machinery. Among these failures, some of the failures may have a slight impact on the mechanical equipment, and some are more serious, and even cause major accidents such as the destruction of the aircraft and the death of people. Experience shows that serious mechanical failures are often caused by some minor failures.
