Wear under bad road conditions
In working conditions with bad road conditions such as mines and construction sites, Engineering Machinery Parts face severe tests. For example, the tires and buckets of loaders wear out quickly. Tires need to frequently travel in harsh environments such as sharp ores and rough ground, which are prone to tread wear, pattern shedding and even blowouts. The bucket is constantly in contact with hard materials, excavation and loading and unloading, and its cutting edge will wear out quickly, resulting in reduced excavation efficiency, and may even be deformed, cracked and damaged, affecting the normal operation of the loader. In addition, the suspension system and chassis of the equipment will also cause loose connections and increased wear of parts due to frequent bumps and impacts, shortening their service life.
Wear under high temperature environment
In some working conditions with high temperature, such as steel mills and cement plants, the wear of Engineering Machinery Parts is also different. The engine and its related accessories work in a high temperature environment, which is difficult to dissipate heat, which can easily lead to oil deterioration and reduced lubrication effect, thereby increasing the wear of parts such as pistons and cylinder walls. High temperature will also accelerate the aging of rubber seals, lose sealing performance, cause oil leakage and other problems, and affect the normal operation of the equipment. At the same time, the strength and hardness of metal materials in high temperature environments may change. For example, under the long-term high temperature, the material performance of parts such as transmission shafts will decrease, and fatigue wear and deformation will occur more easily, increasing the risk of equipment failure.
Wear in high humidity environment
For construction machinery operating in coastal areas or humid environments, high humidity is one of the important factors leading to wear of accessories. High humidity will make the surface of metal accessories more susceptible to oxidation corrosion. For example, the working device of the excavator and the lifting arm of the crane will gradually rust on the surface after being exposed to humid air for a long time, which will not only affect the appearance, but also weaken the strength and wear resistance of the parts and accelerate the wear process. In addition, the humid environment will also affect the normal operation of the electrical system and control system, leading to problems such as line short circuit and component damage, which will affect the performance and reliability of the entire equipment.
Wear under high-intensity operation
In some large-scale engineering construction, construction machinery often needs to work continuously for a long time and at high intensity. The wear problem of accessories under such working conditions is also very prominent. Take a concrete mixer as an example. Its mixing blades and linings are constantly rubbing and colliding with concrete materials during high-intensity mixing operations, causing severe wear. The mixing blades may become thinner, deformed, or even broken due to wear, and the linings will lose their protective function due to wear, causing the mixer barrel to be worn, affecting the mixing quality and equipment life. Similarly, the steel wire rope of a crane is subjected to huge tension and friction during frequent lifting operations, and is prone to wire breakage and wear. Once the steel wire rope is severely worn, it will directly threaten the safety of the lifting operation.
