The use scope of drag chain cable is gradually increasing, and the correct use method is becoming more and more important, which affects the performance and service time of drag chain cable to a certain extent. Therefore, the correct use method has become an important core of drag chain cable, and users should grasp this important element.
1、 Pay attention to the small bending radius of the cable in the drag chain cable.
2、 The laying of drag chain shall not be twisted, that is, the cable shall not be untied from one end of the cable drum or cable reel, but the drum or cable reel shall be rotated first to unfold the cable, and the cable can be unfolded or hung if necessary. The cable used in this occasion can only be obtained directly from the cable coil.
3、 The cables shall be loosely laid side by side in the drag chain, arranged separately as far as possible, separated by spacers or penetrated into the separation cavity of the support neutral. The gap between the cables in the drag chain shall be at least 10% of the cable diameter.
4、 The cables in the drag chain shall not touch each other 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 drag chain shall be 20-30 times of the cable diameter.
6、 If the drag chain breaks, its cable also needs to be replaced, because the damage caused by excessive stretching cannot be avoided. Also, please ensure that the cable moves completely within the bending radius, that is, it cannot be forced to move. In this way, the cables can move relative to each other or with the guide device. After a period of operation, check the position of the cable. The inspection must be carried out after the push-pull movement.
The service life of drag chain cable can be increased only through the correct use method. The above are some small methods and skills, which I hope can bring some help to some colleagues of the cable.
