Selection principle of steel towline
The inner height of the drag chain: select the thickest one among the built-in cables, oil pipes, air pipes, and water pipes as the reference height, plus at least 10% of the height space as the inner height Hi of the drag chain. If the stack is stacked according to the actual height after stacking as the reference height.
Drag chain inner width: select some thicker cables, oil pipes, air pipes, water pipes, etc., and the sum of their outer diameters is used as a reference for the inner width of the drag chain, leaving at least 10% of the width space.
Bend radius: select the largest bend radius among the built-in cables, oil pipes, air pipes, water pipes, etc. as the reference value, and leave more than 10% of the space.
Principles for placing cables, oil pipes, air pipes, and water pipes inside the drag chain
15% of the remaining space should be left, so that the built-in cables, oil pipes, etc. can be freely moved, and there is no pulling force on the drag chain in the radial direction.
Wires with large diameter differences should be laid separately, with uniform weight distribution, and separated by separators if necessary.
During high-speed or high-frequency operation, try to separate the wires from each other horizontally, and do not make them overlap each other. It is recommended to use separators when there are many cables, air pipes, and oil pipes.
