小型混凝土搅拌车工作时间长了之后难免会出现各种损耗，新购机日常使用中可能主要有五方面：磨损速度快、润滑不良、产生松动、发生渗漏现象、操作失误多等等。下面小编就来讲讲相关事项吧。

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.

小型混凝土搅拌车由于新机器零部件加工、装配和调剂等因素的影响，其摩擦表面粗糙，配合面接触面积较小，表面的承压状态不均。机器在运行进程中，零件表面的凹凸部分相互嵌合摩擦，磨落下来的金属碎屑，又作为磨料，持续参与摩擦，更加速了零件配合表面的磨损。

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.

因此，磨合期内轻易造成零部件（特殊是配合表面）的磨损，磨损速度快。这时，假如超负荷作业，则可能导致零部件的破坏，发生早期故障。如：搅拌站主机叶片

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

由于小型混凝土搅拌车新装配的零部件的配合间隙较小，并且由于装配等原因，很难保证配合间隙的均匀性，润滑油（脂）不易在摩擦表面形成均匀的油膜，以禁止磨损。从而下降润滑效能，造成机件的早期异常磨损。严重时会造成配合的摩擦表面划伤或咬合现象，导致故障的发生。

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.

小型混凝土搅拌车新加工装配的零部件，存在着几何外形和配合尺寸的偏差，在应用初期，由于受到冲击、振动等交变负荷，以及受热、变形等因素的影响，加上磨损过快等原因，轻易使本来紧固的零部件发生松动。

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.

此外车辆长期不用时也要进行保养。主要是清洁、清洗、润滑、防护等。目的是预防或减少存放期间各种恶劣条件对机器产生的不良影响，保证车辆经常处于良好的备用状态。

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.
