Control Cables Application
Industries such as aerospace, automation, oil and gas, marine, electrical, and manufacturing commonly employ these flexible shaft, bendable wires. To accommodate commercial and industrial applications the wires are made of high strength metal that is twisted and braided around a core to create stranded wire.
Control cables are essential to the success of many operations and the safety of those operations as common uses include remote-access latch release bowden cables and safety break cables.
To ensure the safety of workers and equipment, it is important to consider the specific qualities of a given control cable system. The diameter, length, thickness, maximum load, and working life of a cable should be compatible with its intended use.
Though referred to simply as cables, control devices are often comprised of an entire wire rope assembly complete with metal or rubber housings. These include wire fittings and terminals such as eyes, forks, studs, handles, pins, and other mounting apparatus with which components are connected. Fittings may be on one or both ends and are often hardwired into the cables for added security, though some instrumentation control cables come with change tool kits for added versatility.
In addition to the aforementioned specifications, the specific type of motorcycle brake cable in use should be considered. Pull-pull and push-pull cables are the most popular choices in the precision transmission of mechanical motion.
Compression in push-pull cables creates motion in one direction while tension pulls it in the opposing direction. This type of control cable is used in hydraulic, pneumatic, and electrical control systems.
With pull-pull cables, tension applies motion in one direction only. Spring actuation is responsible for returning the cable to its starting point. Pull-pull controls are employed when transmission forces require tension.
Either type of control cable must be strong, durable, and able to bend multiple times in many different directions without breaking.
As with all wire rope products, cable housing consist of individual wire filaments which are twisted or braided into strands before being wrapped around a core. Each element of a control cable is crucial to its success. Together the conduit and core selection, the number of bends in the system, and the relative friction between the core and conduit determine the efficiency of control. The housing is also important and may be treated with flame retardant, oil resistance, or other such methods to better function in a particular workplace.
Push pull cable
High density polyethylene liner
High-density polyethylene liner enables push pull wire to work push-pull movement smoothly. It also has the feature of high specific stiffness, resistance to chemicals, lubricity and abrasion quality, so that the cable can keep smooth feeling and durability under the environment from -50 to 100
Conduit type outer casing consists of many hard steel wires stranded around the high-density polyethylene liner by long pitch. With keeping enough flexibility but also stiffness toward compressive load, this outer casing can manage to achieve excellent stroke efficiency without elastic loss.
In concidering the feature of push pull inner wire, we adopted less elastic materials toward tensile load and compressive load. This enabled capable transmission efficiency.
High density polyethlene outer
Excellent weather resistance, resistance to chemicals, and abrasion quality shut out the invasion by a foreign substance. The outer protects conduit outer casing with the best use of stiffness, and transmits push-pull force properly.
Sleeve seal with high abrasion quality and flexibility helps to protect joint parts perfectly, and also holds high-levels of dust resistance and waterproof property.
As is the case with sleeve seal, rod seal is also a protecting seal which has the characteristic of wiper structure. As the push pull inner cable operated, rod seal wipe away the dust and water attached over the rod.
Anticorrosion metal fittings
Hub, sleeve, rod, nut, washer and other parts are all well plated by high corrosion-resistant material.
Rod and sleeve assembled to both end of push-pull cable make the swivel angular movement up to 8°. This angular movement contributes to round and longitudinal movement of joint parts of rod and control arm smoothly and nicely.
How to select push pull cable
Donyorg's push-pull cable lines 4 types of standard series depending on the cable's requested load from 5KG to 100KG. Therefore we can meet a wide range of customer's needs and intended purpose.
When it comes to in use of inner wire rope, we appreciate if customers could preliminarily confirm specifications or conditions such as maximum load, maximum stroke, bending angle, and bending numbers. However, in any event, please feel free to contact us. We are very glad to have your inquiries.
