When selecting a drag chain cable, you need to consider several factors, including the operating environment, the number and type of cables, the length of the drag chain, and the bend radius.
Drag Chain Cable Selection Steps
Determine the drag chain's cross-sectional dimensions: This is a key consideration and directly impacts the drag chain's performance and load-bearing capacity.
Calculate the parameters of internal components: This includes the diameter, length, and weight of cables, tubing, and other components, as well as their arrangement within the drag chain.
Consider the operating environment: Select the appropriate material and protection level to ensure the drag chain is suitable for specific operating conditions.
Calculate the drag chain length: Use the formula Lk = S/2 + ΔM + K to determine the drag chain's length, where S is the travel, R is the bend radius, ΔM is the offset from the center point, and K is a safety margin.
Drag chain cable classifications and characteristics
Steel drag chains: High strength and wear resistance, suitable for heavy-load applications such as machine tools.
Plastic drag chains: Lightweight and corrosion-resistant, suitable for applications such as electronic equipment.
Steel-aluminum drag chains: Combining the advantages of steel and plastic drag chains, suitable for applications where weight and strength are particularly important.
Nylon drag chains: Wear-resistant, corrosion-resistant, and self-lubricating, suitable for environments with high-speed movement and frequent bending.
Installation and Maintenance Recommendations for Drag Chain Cables
Ensure that the cable's bend radius within the drag chain is no less than five times its diameter to prevent damage from excessive bending.
Pay attention to the drag chain's installation method to avoid unnecessary stress on the cable due to improper installation.
Regularly check the cable for wear to identify any problems and perform maintenance.
