FR Vibration Dampers

A Stock bridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines,long cantilevered signs and cable-stayed bridges. The dumbbell-shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main cable. The damper is designed to dissipate the energy of oscillations in the main cable to an acceptable level.

Theory

High-voltage overhead lines have a large gear distance and high towers, and when the conductor is blown by high winds, a strong vibration will occur. When the conductor vibration, the conductor suspension at the working conditions for the unfavorable. Prolonged and periodic vibration, will cause fatigue damage to the wire, so that the wire breaks, broken wire. Sometimes strong vibration will also damage the gold and insulators.

The vibration damper used by the HENVCON for OPGW optical cable is a four resonant frequency vibration damper with tuning fork structure. It is one of the commonly used effective measures to suppress aeolian vibration of conductor, ordinary ground wire and OPGW under tension. The damper is hung on the cable through a clip to transmit the aeolian vibration of the cable to the damper. The hammer heads suspended at both ends of the steel strand can vibrate freely with the movement of the cable, so that the steel strand strands rub against each other, and the vibration energy transmitted to the vibration damper is transformed into the friction heat energy between the steel strand strands and dissipated. By designing each component separately, the damper can have specific performance as a whole.

Feature

1. Reduce Vibration And Noise

Many equipment in the use of the process will produce a certain degree of vibration and noise, these vibration and noise on the equipment and the use of the environment will have a certain impact. The main role of the vibration hammer is to reduce vibration, noise absorption, to protect the equipment and improve the environment.

2. Protection Of Equipment

Vibration damper can reduce the vibration and shock of the equipment, so as to reduce the wear and damage to the equipment. In the vibration, impact and other harsh environments, vibration hammer can play a good role in protecting and extending the service life of the equipment.

3. Improve Equipment Operating Efficiency

Effective Vibration damper can reduce the vibration and noise of the equipment, improve the operational efficiency and stability of the equipment, so that the equipment in the process of running more smoothly and safely.

Summary

In short, vibration damper plays a vital role in the field of electric power, can reduce the vibration and noise of the equipment, protect the equipment, improve the use of the environment, improve production efficiency and quality. For equipment and structures that require the installation of vibration isolation hammer, it is crucial to choose and install the vibration isolation hammer reasonably, if you are interested in this product, please contact HENVCON!
