Some problems that should be paid attention to during the running-in period of the loader will directly affect the future use. So pay attention to the corresponding phenomenon in this link. There are some common phenomena in this regard. You can see what are the phenomena.
1. There is looseness. There are deviations in the geometry and matching dimensions of newly processed and assembled parts. In the early stage of use, due to alternating loads such as impact and vibration, as well as the influence of factors such as heat and deformation, as well as rapid wear and other reasons, it is easy to loosen the originally fastened parts of the loader.
2. Poor lubrication. Due to the small fit clearance of newly assembled parts, and due to assembly and other reasons, it is difficult to ensure the uniformity of the fit clearance, and it is difficult for lubricating oil to form a uniform oil film on the friction surface to prevent wear. Thereby reducing the lubrication efficiency, leading to abnormal early wear of machine parts. In severe cases, the accurately matched friction surface will be scratched or bitten, resulting in failure.
3. Fast wear speed. Due to the influence of the processing, assembly and adjustment of new mechanical parts, the friction surface is rough, the contact area of the mating surface is small, and the surface pressure is uneven. During the operation of the machine, the concave and convex parts of the surface of the loader attachment are embedded and ground, and the metal scraps dropped from the grinding continue to participate in the friction as an abrasive, which accelerates the wear of the mating surface of the part. Therefore, it is easy to cause parts to wear during the running-in period, and the wear rate is fast. At this time, if it is overloaded, it may cause damage to parts and early failure.
4. A leak occurs. Due to the looseness and vibration of machine parts and the influence of machine heat, the sealing surface and pipe joints of the machine will leak out. Some casting, machining and other defects are difficult to find during assembly and debugging, but due to vibration and shock during operation, these defects are exposed and manifest as oil leakage. Therefore, leakage is likely to occur during the running-in period.
