Small concrete mixers will inevitably suffer from various losses after a long working time. There may be five main aspects in the daily use of newly purchased machines: fast wear, poor lubrication, looseness, leakage, and many mistakes in operation. Let's talk about related matters.
Due to the influence of new machine parts processing, assembly and adjustment, the friction surface of small concrete mixer is rough, the contact area of the mating surface is small, and the pressure bearing state of the surface is uneven. During the running process of the machine, the concave and convex parts of the part surface are inlaid with each other for friction, and the worn metal debris, as an abrasive, continues to participate in friction, which further accelerates the wear of the fitting surface of the part.
Therefore, it is easy to cause the wear of parts (especially the mating surface) during the running in period, and the wear rate is fast. At this time, if the operation is overloaded, it may lead to damage of parts and early failure. For example: mixing plant main machine blade
As the fit clearance of newly assembled parts of small concrete mixer truck is small, and due to assembly and other reasons, it is difficult to ensure the uniformity of the fit clearance, lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. Thus, the lubrication efficiency is reduced, resulting in early abnormal wear of parts. If it is serious, it will cause scratch or bite on the mating friction surface, leading to failure.
The newly processed and assembled parts of small concrete mixer have deviations in geometric shape and fit dimensions. At the initial stage of application, due to the impact, vibration and other alternating loads, as well as the impact of heating, deformation and other factors, coupled with rapid wear and other reasons, it is easy to loosen the originally tight parts.
In addition, the vehicle should also be maintained when it is not used for a long time. Mainly cleaning, cleaning, lubrication, protection, etc. The purpose is to prevent or reduce the adverse effects of various harsh conditions on the machine during storage, and ensure that the vehicle is always in good standby state.
