液压货梯安装后会出现哪些问题?

1、 如果发生泄漏,由于零件松动、振动和机器热的影响,机器的密封面和管接头处会发生泄漏;在装配和调试过程中,很难发现铸造、加工等缺陷,但由于运行过程中的振动和冲击,这些缺陷会暴露出来,表现为油(水)泄漏。因此,磨合过程中容易发生泄漏。
1. In case of leakage, leakage will occur at the sealing surface and pipe joint of the machine due to loose parts, vibration and heat of the machine; In the process of assembly and commissioning, it is difficult to find defects such as casting and processing, but these defects will be exposed due to vibration and impact during operation, manifested as oil (water) leakage. Therefore, leakage is easy to occur during running in.
2、 润滑不良,由于新装配零件配合间隙小,以及由于装配等原因,难以保证配合间隙的均匀性,且润滑油(脂)不易在摩擦表面形成均匀的油膜,防止磨损。从而降低润滑效率,引起零件早期异常磨损。严重时,会造成精密配合摩擦表面划伤或咬合,导致失效。
2. Poor lubrication: due to the small fit clearance of newly assembled parts and assembly, it is difficult to ensure the uniformity of fit clearance, and the 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 precision fit friction surface, resulting in failure.
3、 在使用初期,由于受到冲击、振动等交变载荷的影响,以及受热、变形等因素的影响,加上磨损过快的原因,很容易使原来的紧固件松动。3. At the initial stage of use, the original fasteners are easy to loosen due to the influence of alternating loads such as impact and vibration, as well as factors such as heating and deformation, coupled with rapid wear.

4、 由于受新机件加工、装配和调整的影响,摩擦表面粗糙,配合面接触面积小,表面承压不均。在机器运转过程中,零件表面的凹凸部分相互镶嵌摩擦,磨损的金属屑作为磨料继续参与摩擦,加速了零件配合面的磨损。因此,在磨合过程中,容易引起零件(特别是配合面)的磨损,磨损速度快。此时,如果工作超载,可能会导致零件损坏和早期故障。
4. Due to the influence of processing, assembly and adjustment of new parts, the friction surface is rough, the contact area of mating surface is small, and the surface pressure 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 chips continue to participate in the friction as abrasives, accelerating the wear of the fitting surface of the part. Therefore, during the running in process, it is easy to cause the wear of parts (especially the mating surface) and the wear speed is fast. At this time, if the work is overloaded, it may lead to part damage and early failure.
5、 操作中有许多错误。由于对机器的结构和性能缺乏了解(特别是对新的操作人员),容易因操作失误而导致故障甚至机械事故
5. There are many errors in the operation. Due to the lack of understanding of the structure and performance of the machine (especially for new operators), it is easy to cause faults or even mechanical accidents due to misoperation
