Abs1:5 13:42. PSS pipe Support Systems gmbh International Hydraulic Shock Suppressors and Vibration Dampers 1. Hydraulic Shock Suppressors and Vibration Dampers Application Function Hydraulic shock suppressors and vibration dampers In the event of a dynamic load that causes the are components of great relevance to the technical piston to move faster than the locking velocity set safety of pipelines and system components, and by PSS (standard velocity 2 mm/s), the check valve are employed for the purpose of their protection.

7 Closes, the free ow of the silicon oil is impeded, and the shock suppressor absorbs forces. When PSS hydraulic shock suppressors and vibration the pre-set force level is not attained, for instance dampers are employed to prevent damage to when the direction of movement is reversed, apparatuses, pipelines, pressure vessels, valves the check valve opens up again. In the event and pumps, which can occur through suddenly of a vibrating movement, both check valves open acting forces. This includes dynamic load events and close alternately, the shock suppressor which can occur during operation, such as water absorbs the same load in both tension and hammer, pipe bursts or pressure surges caused compression directions.

8 The bypass (or over ow). by blowing off safety valves, as well as cases valve allows the piston to yield as far as the resulting from external events and conditions, de ned nominal load. such as earthquakes, explosions and wind load. Moreover, PSS hydraulic shock suppressors and vibration dampers can be employed in vibrating pipelines and system components where vibration damping is required. Conditions: Amplitude is greater than mm Frequency is in the range 1-33Hz By employing hydraulic shock suppressors and vibration dampers, it is possible to reduce dynamic displacement amplitudes to a minimum. Movements due to temperature change are not hindered by hydraulic shock suppressors and vibration dampers.

When the direction of movement characteristics changes, the second valve can already react before The PSS hydraulic shock suppressors and vibration the rst valve has returned to its initial position. dampers have pressurized hydraulic Systems thus allowing their installation in any position and By employing modern, high-quality sealing and orientation. The uid level of the suppressors guide components, a service life of 40 years can can be easily and accurately veri ed though the be expected from a PSS shock suppressors when position of the piston rods as they relate to each used in nuclear applications.

Depending on the conditions in which Modi cations and alterations, which may be hydraulic shock suppressors and vibration dampers required due to tight installation spaces or in are employed, a maintenance-free period of order to replace shock suppressors from other between ten and 25 years can be assured. manufacturers, can be implemented quickly by modifying the standard components.
