A road roller is a type of operating machinery that utilizes mechanical self weight and vibration to repeatedly load the compacted material, overcome the cohesion and internal friction between materials, eliminate gas and water inside, force material particles to move and wedge each other tightly, increase compactness, and achieve a certain degree of compactness and flatness.

压路机压实作业时应以路基和路面中心线为目标，从左右两边线开始逐趟压向中心线(压路机在纵向长度运行一次为一趟)，直压路机的主轮压到中心线为止，在路中加压那些主轮仍未按要求压到的地方，即“先两边，后中间”。

During the compaction operation of the road roller, the target should be the centerline of the roadbed and road surface, starting from the left and right sides and rolling towards the centerline one by one (the roller runs once in the longitudinal length), until the main wheel of the roller reaches the centerline. In the road, pressurize the areas where the main wheel has not yet pressed as required, that is, "first on both sides, then in the middle".

小型压路机使用完后要必须洗掉其上的污物和灰尘，应特别注意柴油机发电机起动马达喷油泵喷油器液压泵等以及液压管路的外表的清洁，好用干燥柔软的抹布把这些地方擦干净，压路机如果长时间闲置不用须放出发动机水箱内的水，在冬天气候寒冷每天作业完毕后就应放掉仔细清洗掉机器上的污物和灰尘，用煤油擦洗各部件的外表面和一切润滑孔并注一次油脂，对未涂漆的外露部分应涂黄油或防锈胶。所以我们在使用完小型压路机后要进行全方面的清洁，这样才能使小型压路机的寿命增长和效率增高，我们在使用完后要进行全方面的清洁。

After using a small roller, it is necessary to wash away any dirt and dust on it. Special attention should be paid to the cleanliness of the diesel engine generator, starting motor, fuel injection pump, fuel injector, hydraulic pump, etc., and the surface of the hydraulic pipeline. It is best to use a dry and soft cloth to wipe these areas clean. If the roller is idle for a long time, it is not necessary to drain the water in the engine water tank, In cold winter weather, after completing work every day, the dirt and dust on the machine should be carefully cleaned. The outer surface of each component and all lubrication holes should be wiped with kerosene, and grease should be injected once. Unpainted exposed parts should be coated with butter or anti rust adhesive. So after using the small roller, we need to carry out comprehensive cleaning in order to increase its lifespan and efficiency. After use, we need to carry out comprehensive cleaning.

随着“想致富先修路”的口号响彻整个，道路装修业也随着发展下来，并且带动了机械业中小型压路机销售量，但是我们在购买完小型压路机后会有一定时间的磨合期，在这磨合期之间会产生很多问题，下面就由小编为您介绍一下吧！

With the slogan of "building roads first if you want to become rich" resounding throughout China, the road decoration industry has also developed and driven the sales of small and medium-sized rollers in the mechanical industry. However, after purchasing small rollers, we will have a certain period of running in, during which many problems will arise. Let me introduce it to you!

磨损速度快：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。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。

Fast wear rate: Due to factors such as processing, assembly, and adjustment of new machine components, their friction surface is rough, the contact area of the mating surface is small, and the pressure state of the surface is uneven. During the operation of the machine, the concave and convex parts on the surface of the parts are intertwined and rubbed against each other, and the metal debris that falls off is used as abrasive to continuously participate in friction, further accelerating the wear of the mating surface of the parts. Therefore, during the running-in period, it is easy to cause wear on the parts, especially the mating surface, with a fast wear rate.

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，以禁止磨损。

Poor lubrication: Due to the small fit clearance of newly assembled components and due to assembly reasons, it is difficult to ensure the uniformity of the fit clearance. Lubricating grease is not easy to form a uniform oil film on the friction surface to prevent wear.

产生松动：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。

Loosening: Newly processed and assembled components have deviations in geometric appearance and fitting dimensions. In the early stages of application, due to alternating loads such as impact and vibration, as well as factors such as heat and deformation, coupled with rapid wear and tear, the originally fastened components can easily become loose.
