磨合期是保证装载机正常运转、降低故障率、延长其使用寿命的重要环节,对装载机磨合期的适用与保养应引起充分重视,在此之前我们应该了解磨合期有啊很么特点,以便更好的对装载机进行维护。
1、操作失误多
由于对机器的结构、性能的了解不够,容易因操作失误引起故障,甚至引起机械事故。
As the understanding of the structure and performance of the machine is not enough, susceptible to failures caused by operational errors, and even cause mechanical accident.
2、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。严重时会造成精密配合的摩擦表面划伤或咬合现象,导致故障的发生。
Since the new assembly parts with the gap is small, and due to assembly and other reasons, it is difficult to ensure uniformity with the gap, the lubricating oil on the friction surface is not easy to form a uniform film to prevent wear. Thereby reducing the lubrication performance, resulting in the early parts of abnormal wear. Will cause serious friction with precision surface scratches or bite phenomenon, leading to failure.
3、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。
The new processing and assembly of components, there is a deviation geometry and with the size of the initial use, due to shock, vibration, etc. alternating load, and the effects of heat, deformation and other factors, coupled with excessive wear and other reasons, easy to make original loosening the fastening parts.
4、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,表现为漏油,因此,磨合期容易出现渗漏现象。
Since the sealing surface of the fitting parts and loose, vibration combined heat machine, the machine will be logged off leakage, part of the casting defects in the assembly and processing debugging difficult to find, but during the operation of the vibration, shock, role of this flaw is exposed, the performance of oil, therefore, prone to leakage of the run.
5、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。
As the impact of the new machine parts processing, assembly and adjustment factors, the friction surface is rough, with surface contact area is small, uneven surface pressure situation. The machine during operation, some parts convex surface friction fitted into each other, grinding down to the metal debris and continue to participate as an abrasive friction, more accelerated wear parts with surfaces. Therefore, run-in period is likely to cause wear and tear parts, wear faster. At this time, if overload operation, it may cause damage to the components, resulting in premature failure.
