Vibration-reducing support device for pipeline system

Abstract

The invention discloses a vibration-reduction support device for a pipeline system, and relates to the field of vibration absorption and isolation devices for pipeline systems. The vibration-reduction support device comprises a supporting part and at least one vibration absorber, wherein the supporting part is made of damping materials and provided with a channel used for supporting and fixing a pipeline; and each vibration absorber comprises a mass block and at least two springs arranged in the supporting part. Meanwhile, the supporting part is internally provided with accommodating cavities with the quantity corresponding to the quantity of the vibration absorbers, each mass block is accommodated in the corresponding accommodating cavity, every two springs are connected to the corresponding mass block and used for elastically maintaining the mass block in the corresponding accommodating cavity, and each accommodating cavity provides a vibration space for vibration of the corresponding mass block in any direction. The vibration-reduction support device for the pipeline system can absorb and dissipate vibration energy of the pipeline connected with the support device through the damping materials, vibration which is not dissipated is transmitted the vibration absorbers, the springs and the mass blocks in the vibration absorbers are driven to generate damping vibration, and thus the double effects of absorbing and isolating vibration in all directions of the pipeline system in the whole frequency band are achieved.

Description

technical field [0001] The invention relates to the field of vibration-absorbing and vibration-isolating devices for pipeline systems, in particular to a vibration-damping support device for pipeline systems. Background technique [0002] Due to the existence of internal excitations such as pumps and valves and external excitations such as foundation or decking vibrations in large-scale and complex piping systems, vibrations in the piping structure and fluid in the piping will be induced, and the vibrations of these piping structures and fluids will also couple with each other to generate fluid-solid Coupling vibration enables the pipeline system to transmit the vibration energy to various positions of the pipeline system along the pipe wall and the fluid in the pipe while transporting the fluid, causing damage to the pipeline and other components connected to it and precision instruments, affecting the pipeline system. The safety of the road system and the normal operation ...

Problems solved by technology

Although this utility model solves the problem of the single vibration absorption frequency of the existing vibration absorber to a certain extent, it can only have a good absorption effect on the vibration in the direction where the spring is set and is close to the resonance frequency of the spring, and cannot achieve simultaneous absorption in the entire frequency band. and the effect of isolating the vibration of the piping system in all directions
