Vibration damper

fluid

Additional linear support which stop undesirable sudden mouvement of severals components. The snubbers allow low displacement of the components, but stop and block all high speed undesirable displacement, due to earthquake, opening of safety valves, pipes rupture... Snubbers (or dampers) are linear units designed to limit sudden unwanted movements in components such as : •Piping •Storage tanks •Control valves •Steam generators •Safety valves •Pumps, motors etc. The devices enable slow movements due to thermal dilatation in both directions and oppose only low resistance to such movements. But when the movement speed leads to dynamic forces that are harmful to the installation, the snubbers are immediately locked at the desired set speed and support the dynamic force by transferring it to the fixed structure. Once the disturbance has passed, the device returns to its initial state and enables slow movements once again. In that way, the devices provide temporary additional support to the installation in order to prevent it from entering into resonance, thereby eliminating the risk of breaking due to vibrations. The devices therefore prevent damage due to : •Earthquakes •Water hammer effects •Violent thrusts due to safety valve discharge •Strong gusts of wind •Other similar disturbances
