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.

潤滑不良由于新裝配的零部件的配合間隙較小，并且由于裝配等原因，很難保證配合間隙的均勻性，潤滑油（脂）不易在摩擦表面形成均勻的油膜以阻止磨損。從而降低潤滑效能，造成機件的早期異常磨損。嚴重時會造成配合的摩擦表面劃傷或咬合現象，導致故障的發生。

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.

磨損速度快由于新機器零部件加工、裝配和調整等因素的影響，其摩擦表面粗糙，配合面接觸面積小，表面的承壓狀況不均。機器在運行過程中，零件表面的凹凸部分相互嵌合摩擦，磨落下來的金屬碎屑又作為磨料繼續參與摩擦，更加速了零件配合表面的磨損。因此，磨合期內容易造成零部件（特別是配合表面）的磨損，磨損速度快。這時，如果超負荷作業，則可能導致零部件的損壞，產生早期故障。

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.

發生松動新加工裝配的零部件，存在幾何形狀和配合尺寸的偏差，在使用初期，由于受到沖擊、振動等交變負荷，以及受熱、變形等因素的影響，加上磨損過快等原因，容易使原來緊固的零部件產生松動。

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.

發生滲漏現象由于機件的松動、振動合機器受熱的影響，機器的密封面以及管接頭登出會出現滲漏現象，部分鑄造、加工等缺陷在裝配調試時難于發現，但由于作業過程中的振動、沖擊作用，這種缺陷就被暴露出來，表現為漏（滲）油（水），因此，磨合期容易出現滲漏現象。

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.
