你知道混凝土全自动搅拌车配件磨合期是什么样吗?

自动上料搅拌车配件也是装载机的重要部分,若在操作过程中由于失误对机器的结构、性能的了解不够(特别是新的操作者),容易因操作失误引起故障,甚至引起机械事故。今天小编就带大家来看一下搅拌车配件磨合期。
Automatic loading mixer accessories are also an important part of the loader. If you don't know enough about the structure and performance of the machine (especially the new operator) due to mistakes in the operation process, it is easy to cause faults and even mechanical accidents. Today, I'll take you to see the running in period of mixer accessories.
润滑不良由于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阻止磨损。从而降低润滑效能,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。
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 fit clearance, Lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear, so as to reduce the lubrication efficiency and cause early abnormal wear of parts. In serious cases, it will cause scratch or bite on the mating friction surface, resulting in failure.
磨损速度快由于新机器零部件加工、装配和调整等因素的影响,其摩擦表面粗糙,配合面接触面积小,表面的承压状况不均。机器在运行过程中,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继续参与摩擦,更加速了零件配合表面的磨损。因此,磨合期内容易造成零部件(特别是配合表面)的磨损,磨损速度快。这时,如果超负荷作业,则可能导致零部件的损坏,产生早期故障。
The wear speed is fast. Due to the influence of processing, assembly and adjustment of new machine parts, the friction surface is rough, the contact area of mating surface is small, and the pressure bearing condition of the surface is uneven. During the operation of the machine, the concave convex parts of the part surface are embedded and rubbed with each other, and the worn metal debris continues to participate in the friction as abrasive, which further accelerates the wear of the fitting surface of the part. Therefore, during the running in period, it is easy to cause the wear of parts (especially the mating surface) and the wear speed is fast. At this time, if the operation is overloaded, it may lead to the damage of parts and early failure.
发生松动新加工装配的零部件,存在几何形状和配合尺寸的偏差,在使用初期,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,容易使原来紧固的零部件产生松动。
In the early stage of use, due to the impact, vibration and other alternating loads, as well as the influence of heating, deformation and other factors, coupled with the rapid wear and other reasons, it is easy to loosen the originally fastened parts.
发生渗漏现象由于机件的松动、振动合机器受热的影响,机器的密封面以及管接头登出会出现渗漏现象,部分铸造、加工等缺陷在装配调试时难于发现,但由于作业过程中的振动、冲击作用,这种缺陷就被暴露出来,表现为漏(渗)油(水),因此,磨合期容易出现渗漏现象。
Leakage occurs. Due to the loosening of mechanical parts, vibration and the influence of machine heating, leakage will occur on the sealing surface and pipe joints of the machine. Some casting, processing and other defects are difficult to find during assembly and commissioning, but these defects are exposed due to vibration and impact during operation, It is characterized by oil (water) leakage. Therefore, leakage is easy to occur in the running in period.
