The professional concrete mixing station staff summarized that there may be five aspects in the daily use of the newly purchased concrete mixing plant: fast wear, poor lubrication, loosening, leakage, and many operating errors. Which aspects of the concrete mixing station need strict requirements?
1. Which parts of the concrete mixing plant wear fast?
Due to the influence of new machine parts processing, assembly and adjustment, the concrete mixing station has a rough friction surface, a small contact area on the mating surface, and an uneven pressure state on the surface. During the operation of the machine, the concave and convex parts on the surface of the part are fitted and rubbed with each other, and the metal chips that have fallen off are also used as abrasives to continuously participate in friction, which accelerates the wear of the mating surface of the part. Therefore, the parts (especially the mating surfaces) are easily worn during the running-in period, and the wear speed is fast. At this time, if the work is overloaded, parts may be damaged and early failure may occur. Such as: the blades of the host of the mixing station.
2. What are the consequences of poor lubrication in the concrete mixing plant?
Because the fitting gap of the newly assembled components of the concrete mixing station is small, and due to assembly and other reasons, it is difficult to ensure the uniformity of the fitting gap, and the lubricant (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. As a result, the lubricating efficiency is reduced, causing early abnormal wear of the parts. In severe cases, it can cause scratches or occlusions of the friction surface of the precision fitting, resulting in failure.
3. What are the main causes of loosening in concrete mixing plant?
The newly processed and assembled parts of the concrete mixing station have deviations in geometric shapes and matching dimensions. In the initial stage of application, due to alternating loads such as shock and vibration, as well as heat and deformation, and excessive wear and other reasons , Easy to loosen the originally fastened parts.
