小型混凝土攪拌車工作時間長了之后難免會出現各種損耗，新購機日常使用中可能主要有五方面：磨損速度快、潤滑不良、產生松動、發生滲漏現象、操作失誤多等等。下面小編就來講講相關事項吧。

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.

小型混凝土攪拌車由于新機器零部件加工、裝配和調劑等因素的影響，其摩擦表面粗糙，配合面接觸面積較小，表面的承壓狀態不均。機器在運行進程中，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，持續參與摩擦，更加速了零件配合表面的磨損。

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，磨合期內輕易造成零部件（特殊是配合表面）的磨損，磨損速度快。這時，假如超負荷作業，則可能導致零部件的破壞，發生早期故障。如：攪拌站主機葉片

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

由于小型混凝土攪拌車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，以禁止磨損。從而下降潤滑效能，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。

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.

小型混凝土攪拌車新加工裝配的零部件，存在著幾何外形和配合尺寸的偏差，在應用初期，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，輕易使本來緊固的零部件發生松動。

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.

此外車輛長期不用時也要進行保養。主要是清潔、清洗、潤滑、防護等。目的是預防或減少存放期間各種惡劣條件對機器產生的不良影響，保證車輛經常處于良好的備用狀態。

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.
