Application and installation precautions of drag chain cable

by:AAA     2020-02-27
Drag chain cable is mainly used in industrial automation system, production line system, welding machine robot, submersible, handling robot, numerical control machine tool and metallurgical industry, and needs to move back and forth. In order to prevent the cable from being entangled, worn, pulled off, hung and scattered, the cable is often put into the cable drag chain. The cable of the drag chain is used, ordinary drag chain cable has the advantages of bending performance, mobile flexibility, wear resistance, oil resistance, tensile resistance, etc. It is usually used in automatic enterprise assembly line Workshop, electric welding machine robot arm, ocean detection instrument, engraving machine and other automatic mobile equipment. Special drag chain cable has the advantages of cold resistance, oil resistance, seawater resistance, chemical resistance, low temperature resistance, extrusion resistance, etc. It is mainly used in places with harsh outdoor environment and strict requirements on cables, such as marine operation automation system, instruments and meters, shallow sea robots, chemical automation equipment, and special flexible drag chain cables for metallurgical Automation Enterprises. Matters needing attention in the installation of tow chain Cable 1. The laying of tow chain cable should not be twisted, that is, the cable should not be untied from one end of the cable drum or cable tray, but the cable should be unfolded by rotating the drum or cable tray first, the cable can be unfolded or hung up when necessary. Cables used for this occasion can only be obtained directly from cable volumes. 2, must pay attention to the minimum bending radius of the cable, the installation radius is not small 6 times the diameter of the cable. 3. The cables must be loosely laid side by side in the drag chain, and be arranged as separately as possible. Separate them with spacers or penetrate into the separation cavity of the neutral bracket, the gap between cables in the tow chain shall be at least 10% of the cable diameter. 4. The cables in the drag chain shall not contact or be trapped together. 5. Both points of the cable must be fixed, or at least at the moving end of the drag chain. Generally, the distance between the moving point of the cable and the end of the tow chain should be 20-30 times. 6, please ensure that the cable is completely moved within the bending radius, that is, can not be forced to move. In this way, the cables can move relative to each other or with the guiding device. After a period of operation, it is best to check the position of the cable. This check must be carried out after the push-pull move. 7. If the drag chain is broken, its cable also needs to be replaced, because damage caused by excessive stretching cannot be avoided.
