Strengthening the production of plastic drag chains

Bridge engineering plastic nylon drag chainBasic Parameters

(1) Material: Reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and wear resistance, flame retardancy, and stable performance at high and low temperatures, can be used outdoors. The amount of nylon content determines the strength and wear resistance of the drag chain, as well as the noise level during operation. The nylon content ranges from 5% to 17%, but does not exceed 19%. Generally, the content is around 30%.
(2) Resistance: resistant to oil and salt, and has a certain degree of acid and alkali resistance.
(3) Operating speed andhighestSpeed: The maximum speed can reach 5 meters per second, and the maximum acceleration can be 5 meters per second (specific speed and acceleration depend on the operating conditions).
(4) Operating lifespan: Under normal overhead use, it can achieve up to 5 million reciprocating motions (specific lifespan depends on operating conditions).
Bridge engineering plastic nylon drag chainSelection principle
Internal height: Select the thickest cable, oil pipe, air pipe, water pipe, etc. as the reference height, and add at least 10% of the height space as the internal height of the drag chain If overlapping, use the actual height after overlapping as the reference height.
Inner width: Choose thicker cables, oil pipes, air pipes, water pipes, etc., and use the sum of their outer diameters as a reference for the inner width of the drag chain, leaving at least 10% width space.
Bending radius: Choose from built-in cables, oil pipes, air pipes, water pipes, etcmaximumThe bending radius is used as a reference value, and there is more than 10% space left. The principle for placing cables, oil pipes, water pipes, and air pipes inside the drag chain is as follows.
There should be a remaining space of 15% to allow for the free movement of built-in cables, oil pipes, etc., without causing tension on the drag chain in the radial direction.
Conductors with large differences in diameter should be laid separately and distributed evenly in weight. If necessary, separators can be used to separate them.
When operating at high speeds or frequencies, try to keep the wires horizontally separated from each other and avoid overlapping them. It is recommended to use separators when there are many cables, gas pipes, oil pipes, etc.

Plastic drag chains can be divided into bridge type plastic drag chains and fully enclosed plastic drag chains according to their structure; According to the model, it is divided into small drag chains, general drag chains, and large drag chains; According to the noise coefficient, it can be divided into ordinary drag chains andmuteDrag chain; According to their form, they can be divided into ordinary drag chains, parallel drag chains, and S-shaped drag chains; According to the raw materials, it is divided into original packaging plastic and recycled plastic.
The model of plastic drag chain is generally determined based on the internal height and width, as it is not a standard product and the external dimensions vary from manufacturer to manufacturer.
The models of plastic drag chains include 7 * 7, 10 * 10, 10 * 15, 15 * 15, 15 * 20, 15 * 35, 15 * 40, 15 * 40, 15 * 50, 18 * 18, 18 * 25, 18 * 35, 18 * 50, 18 * 60, 25 * 25, 25 * 38, 25 * 57, 25 * 77, 25 * 103, 35 * 50, 35 * 60, 35 * 75, 35 * 100, 35 * 125, 35 * 150, 35 * 175, 35 * 200, 45 * 50, 45 * 60, 45 * 75, 45 * 100, 45 * 125, 45 * 150, 45 * 200, 56 * 95, 56 * 125 56 * 175, 56 * 200, 56 * 300, as well as 55, 62, 65, 80 series drag chains
