Engineering plastics drag chain maintenance and repair knowledge

Engineering plastics drag chains, like all mechanical equipment, need to be regularly maintained and repaired in order to maintain a good working condition and increase the service life, so that hidden dangers can be discovered and eliminated in time to prevent accidents, thereby ensuring safe operation and reducing losses.


For the newly purchased cable chains, the friction between each unit chain is not used, so the friction is large. In order to reduce the friction, some lubricants may be properly added to reduce the friction, increase its flexibility, be careful not to add too much, and prevent Lubricant splashes on the opening of the cover to prevent it from falling off during operation, causing unnecessary loss.


In the process of using plastic drag chains, you can make a change of view. The so-called “listening” is to listen to the sounds of the drag chain in operation. The sound is single and light during normal operation. It runs almost silently. After a long service life, when problems occur, such as cracks, the sound will be harsh. The sound appears, and the second is to do regular inspections. The first is the joint. The main problem is whether the mounting hole has any problems. Followed by the shaft, see the wear situation. Once again, the cover plate and the mounting hole are inspected to see if there are any cracks, and if there is a slippage phenomenon in the mounting hole. The replacement is to find the defective unit chain and replace the new one, so as to prevent the problem from becoming larger and causing greater losses. Of course, when there is a big problem, it needs to be replaced completely.
