As said “Every change is a challenge” same is the case of equipment’s which are constantly exposed to extreme weather and temperature. Often equipment’s in the
defence systems have to tackle the tough terrains, rough seas and air turbulence during their routine foray. Extreme conditions pose maximum effect on the working of machines and sensitive electronic devices. Even in industrial environment, machines are exposed to chemicals, oils and water which is quite harmful for equipment and machines. Further, effects of constant shock loads and vibration can lead to irreversible damage on equipment if not taken care off. This is when wire rope isolators come in the picture to effectively counter forces and protect sensitive equipment and machines.
The beauty of wire rope isolator lies in its simple construction and effective performance in providing necessary protection to all sensitive devices. Construction of these cable Isolators typically comprises of stainless steel stranded cable, threaded through aluminium alloy retaining bars or holding brackets, crimped and mounted for effective vibration isolation. There is a thorough scientific engineering that is behind the design of a wire rope isolator wherein various parameters are taken in to account to ensure its effectiveness. One of the core element in these equipment’s which is the stainless steel stranded cable, needs to be of specific diameter and diameter of loop to be suitable for specific vibration damping requirements.
The elasticity of the loop in a wire rope isolator acts as a spring which deflects under load and dissipates the vibrational energy from the source of vibration. This ensures minimum transfer of vibration to the corresponding elements and in turn protects them from any undue damage. By the general law of deflection, 5 to 15 per cent is what the isolators can take easily and deflect to suit the requirement. Some of the prominent characteristics that makes wire rope isolators the first choice is its ability to provide suitable deflection when stressed under load, offering high damping ratio.
Wire rope isolators offer adequate corrosive protection and capable to operate at a temperature range of minus 125 Degree Celsius to 350 Degree Celsius. Construction and built of wire rope isolators enables them to deliver the exact amount of isolation and damping to each application making it an ideal application to any machines or devices. The selection of the wire rope is extremely critical for any application involving the wire rope isolator. Several parameters are to be taken in to account when selecting wire rope isolators for vibration dampening and this includes diameter of the wire, number of strands, wire length, wire twist. For those machines with space constrain, compact wire rope isolator is the answer to it. The capacity of wire rope isolator is the number of strands per section that defines the deflection characteristics and damping capability. With construction comprised of stainless steel cable and aluminium alloy brackets makes this equipment long lasting and durable solution.
