装载机磨合期常见几大问题

Several common problems in the running in period of Loaders


 贵州直喷装载机直销

贵州直喷装载机直销认为装载机出厂后,一般规定有60小时左右的磨合期(有的称为走合期),这是根据装载机使用初期的技术特点而规定。

The direct injection loader of Guizhou thinks that after loading a factory, there are generally 60 hours running in period.


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。部分用户由于缺乏装载机使用常识或是因为工期紧、或是想尽快获得收益而忽视新机磨合期的特殊技术要求。有的用户甚至认为,反正厂家有包修期,装载机坏了由厂家负责维修,于是机器在磨合期内就长时间超负荷使用,导致机器早期故障频繁发生,这不仅影响了机器的正常使用、缩短了机器的使用寿命,而且还因为机器损坏影响了工程进度。因此,对装载机磨合期的适用与保养应引起充分重视。

The running in period is an important link to ensure the normal operation of the loader, reduce the failure rate and prolong the service life of the loader. Some users ignore the special technical requirements of the new machine's running in due to lack of common sense of loaders or because of tight schedule or the desire to gain income as soon as possible. Some users even think, anyway, manufacturers have the warranty period, the loader is broken by the manufacturers responsible for the maintenance of the machine, so in the run in period is long time overload, causing the machine fault occurs frequently, which not only affects the normal use of the machine, shorten the service life of the machine, but also because of damage to the machine impact engineering schedule. Therefore, the application and maintenance of the loader's running in period should be paid full attention to.


1.磨损速度快

1. fast wear speed

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。

Due to the influence of new machine parts processing, assembly and adjustment, the friction surface is rough, the contact area of the mating surface is small, and the surface pressure condition is uneven. During the running of machine, the concave and convex parts of parts surface are embedded with each other. The metal debris worn down as abrasive continues to participate in friction, which accelerates the wear of parts matching surfaces. Therefore, the wear of parts (especially with the surface) is easily caused during the running in period, and the wear speed is fast. At this time, if the overload operation, it may cause the damage of the parts and produce an early fault.

2.润滑不良

2. bad lubrication

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。严重时会造成精密配合的摩擦表面划伤或咬合现象,导致故障的发生。

Due to the smaller mating gap of new assembly parts, and because of assembly and other reasons, it is difficult to ensure the uniformity of the fit clearance. Lubricating oil (grease) is not easy to form uniform oil film on the friction surface to prevent wear. Thus, the lubrication efficiency is reduced and the early abnormal wear of the machine parts is caused. In serious case, it will cause the scratch or bite of the friction surface of the precise coordination, which leads to the occurrence of the fault.

3.发生松动

3. loosening

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 assembly parts, with the size of the existing geometry and deviation, in the initial stage, due to shock, vibration and impact of alternating load, heating, deformation and other factors, such as excessive wear and easy, so that the original fastening parts loosening.

4.发生渗漏现象

4. occurrence of leakage

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。

Due to the influence of mechanical loosening, vibration machine heating, sealing surface machine and pipe joint out leakage, part of casting and machining defects such as difficult to find in assembling and debugging, but because of vibration, the working process of the impact, the defects will be exposed, as leakage (infiltration) oil (water), therefore, prone to leakage in.

5.操作失误多

5. errors in operation

由于对机器的结构、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。

Because of the lack of understanding of the structure and performance of the machine (especially the new operator), it is easy to cause failure due to operation errors and even cause mechanical accidents.
