Pipeline vibration reduction device and configuration method thereof

Abstract

The invention relates to a pipeline vibration reduction device and a configuration method thereof. The pipeline vibration reduction device comprises a plurality of bottom plates, the plurality of bottom plates are sequentially hinged end to end through hinges to form a long chain, the long chain is wound on a pipeline, an L-shaped connecting plate is hinged to each of the bottom plates at the twoends of the long chain through hinges, the opposite end faces of the two L-shaped connecting plates are respectively provided with holes, and the two L-shaped connecting plates are connected through bolts; and the outer end face of each bottom plate is movably connected with a frequency-adjustable vibration absorber for absorbing vibration. The pipeline vibration reduction device is simple in structure, the vibration absorbers and the bottom plates are movably connected, the two L-shaped connecting plates are movably connected, and installation is convenient. The frequencies of the vibration absorbers are adjustable, so that vibration of the synchronous condenser connection pipeline can be suppressed, and long-term stable use of the pipeline is guaranteed. The pipeline vibration reductiondevice can also be popularized and applied to suppressing vibration of various frequencies of different models of pipelines.

Description

technical field [0001] The invention belongs to the technical field of pipeline anti-vibration, and in particular relates to a pipeline anti-vibration device and a configuration method thereof. Background technique [0002] Large rotating equipment such as synchronous condensers, steam turbines, generators, and pumps will vibrate under working conditions, and these vibrations will be transmitted to the pipelines connected to them. Although the vibration of the rotating equipment and the influence of the unstable flow of the fluid on the pipeline will be considered in the design, the vibration will still exceed the standard in some cases. In this case, if the spatial structure of the pipeline or the bearing support If the hanger is installed, it needs to be shut down for pipeline reconstruction. The amount of pipeline renovation is large, the construction period is long, and the maintenance requirements for system equipment during shutdown are high, and the cost is high. C...
