Based on the functional analysis of the execution system of the large loader, the small loader has innovated the design of the loader, and designed the agricultural tractor into a practical loader. Its different models meet the needs of small and medium-sized construction enterprises. So, what are the precautions for small loaders during the running-in period? Next, let's take a look.
1. Fast wear and tear
Due to the processing, assembly and adjustment of the new machine parts of the small loader, 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 on the surface of the parts are embedded in each other, and the worn metal chips continue to participate in the friction as abrasives, which accelerates the wear of the mating surfaces of the parts. Therefore, the parts (especially the mating surfaces) are easy to wear during the running-in period, and the wear rate is fast. At this time, if overloaded, it may cause damage to the parts and cause early failure.
2. Poor lubrication
Due to the small fitting clearance of the newly assembled parts of the small loader, and due to the reasons for the assembly, it is difficult to ensure the uniformity of the fitting clearance, and it is difficult for the lubricating oil (grease) to form a uniform oil film on the friction surface to prevent wear. As a result, the lubrication efficiency is reduced, resulting in abnormal early wear of machine parts. In severe cases, it can cause scratches or bite marks on precisely-fitting friction surfaces, leading to failure.
3. Loosening occurs
There are deviations in the geometry and fit dimensions of newly machined and assembled parts for small loaders. In the early stage of use, due to the influence of alternating loads such as shock and vibration, as well as the influence of factors such as heat and deformation, and the rapid wear and tear of the reasons, the originally fastened parts are easy to loosen.
4. Leakage occurs
Due to the loosening and vibration of the machine parts of the small loader and the influence of the machine heating, the sealing surface and pipe joints of the machine will leak, and it is difficult to find some defects such as casting and machining during the assembly and debugging process. However, due to the vibration and shock acting during operation, these defects are exposed and manifested as oil (water) leakage, so leakage is easy to occur during the running-in process.
5. There are many mistakes in operation
Due to insufficient understanding of the structure and performance of small loaders (especially for new operators), it is easy to cause malfunctions or even mechanical accidents due to operational errors.
The above are the precautions for small loaders during the running-in period. It is a kind of earth and stone construction machinery widely used in highway, railway, hydropower, construction, port, mine and other construction projects.
