What is the characteristic of the wire rope electric hoist in the use of grinding period?
The lubrication between machine parts is not good enough: because of the smaller mating gap of new assembly parts, and because of assembly and other reasons, it is difficult to ensure the uniformity of the clearance. Lubricating oil is not easy to form uniform oil film on the friction surface, so as 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.
Loose parts: loose new processing and assembling parts, there is geometry and size 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. Electric wire rope hoist any newly purchased mechanical products have a certain period, on the wire rope electric hoist is the same, it is very important to do the work of running in the electric wire rope hoist in use process, because it should be as soon as possible into industrial applications, improve the efficiency of the work.
So what is the state of wire rope electric hoist in the period of running in? As shown below: electric hoist electric hoist electric hoist use the characteristics of the running in. Any newly purchased mechanical products have a certain period, on the wire rope electric hoist is the same, it is very important to do the work of running in the electric wire rope hoist in use process, because it should be as soon as possible into the industrial application, improve the work efficiency of the project. So what is the state of a wire rope electric hoist in the period of running in? As shown below:
The surface pressure is uneven: the wear speed is fast, 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 operation of lifting tools, the concave and convex parts of the parts are embedded with each other, and the metal debris is worn away. As an abrasive, they continue to participate in the friction and accelerate the wear of the parts. 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.
