AI Technical Summary

Technical Problem

Existing pipeline vibration reduction devices are difficult to install and have poor vibration reduction effects, and cannot effectively prevent pipeline connections from loosening or leaking due to vibration.

Method used

A pipeline axial and radial coupled multi-frequency dynamic vibration reduction device is designed. It adopts a support ring, a first and a second spring, a preset rod assembly and other structures. The preset rod assembly maintains the support ring spacing before installation, realizes the preload force of the spring, simplifies the installation process, and realizes axial and radial vibration reduction through the inertia of the spring.

Benefits of technology

It achieves effective vibration reduction of pipeline axial and radial vibration, prevents loosening and leakage of connection parts, is easy to install, and is suitable for high-temperature and high-pressure medium pipelines.

Abstract

The present invention discloses a multi-frequency dynamic vibration reduction device for pipelines that is coupled axially and radially, aiming to address the shortcomings of existing pipeline vibration reduction devices, such as the troublesome installation and poor vibration reduction effect. The present invention solves the above-mentioned technical problems through the following technical solutions: a support ring is arranged along the axial direction of the pipeline, and a ring sleeve for clamping onto the pipeline surface is provided inside the support ring; a first spring is tensioned and connected between the half ring and the half sleeve along the radial direction of the support ring, and a first counterweight is provided on the first spring; a second spring is tensioned and connected between the two groups of support rings, and a second counterweight is provided on the second spring; a preset rod assembly is inserted into the second spring, and its two ends are respectively connected to the two groups of support rings, which are used to limit the distance between the two groups of support rings before the half sleeve clamps onto the pipeline surface. The second counterweight on the second spring can reduce the axial vibration of the pipeline through inertia, and the arrangement of the first spring and the first counterweight can reduce the radial vibration of the pipeline, effectively improving the vibration reduction effect of the pipeline.
