What should I pay attention to when using a hydraulic freight elevator for the first time?

点击浏览: Release time: 2019-07-02Click to browse: Source: Longzhu Machinery- Lift Freight Lift Manufacturer

The hydraulic freight elevator as a mechanical equipment requires a running-in period when it is first used. This time is not only the process of human-machine adaptation, but also the process of equipment self-adaptation. So what should be paid attention to when the hydraulic freight elevator is used for the first time? The following editors will introduce it to everyone.

From the machine itself. When the device was first used, it was also the fastest wearing period. Due to the factors such as the processing, assembly and adjustment of the parts of the hydraulic freight elevator, the friction surface is rough, the contact area of the mating surface is small, and the surface pressure condition is uneven. During the operation of the machine, the concave and convex parts on the surface of the part are fitted and rubbed against each other, and the metal chips that have fallen off are used as abrasives to continue to participate in friction, which further accelerates the wear of the mating surface of the part. Therefore, during the running-in period, it is easy to cause the wear of parts (especially the mating surface), and the wear speed is fast. At this time, if you do not pay attention to maintenance, but carry out overload work, you will accelerate the damage of the hydraulic freight elevator early.

初次使用液压货梯时需要注意什么?

Because the fitting clearance of newly assembled parts of the hydraulic freight elevator is small, and due to assembly and other reasons, it is difficult to ensure the uniformity of the fitting clearance. If the lubrication is poor, it is not easy for the lubricating oil to form a uniform oil film on the friction surface to prevent wear, thereby reducing the lubrication efficiency , Causing early abnormal wear of the parts. In severe cases, it can cause scratches or occlusions of the friction surface of the precision fitting, resulting in failure.

Newly processed hydraulic freight elevator equipment is prone to loose parts. In the initial stage of use, due to the impact of alternating loads such as shock and vibration, as well as heat and deformation, coupled with excessive wear and other reasons, it is easy to loosen the original tightened parts. So be sure to check the parts of the equipment frequently for signs of looseness.

Leakage is also possible due to the tightness of the seal. Affected by the looseness of the parts, vibration and heat of the machine, leakage will occur at the sealing surface and pipe joints of the machine; some casting and processing defects are difficult to find during assembly and debugging, but due to vibration during the operation , Impact, this defect is exposed, manifested as oil leakage. Therefore, leakage occurs easily during the running-in period.

It also takes a certain amount of time for the operating personnel and the hydraulic freight elevator equipment to run in. Before using the operating personnel, they must be aware of reading instructions and precautions, and understand the performance and principle of the machine, so as to avoid serious accidents due to improper operation.
