摘要

针对原油管道上的压力表振动大、指针来回甩动,无法准确读出压力值的问题,本文运用颗粒阻尼技术开展了压力表及其下方细管的减振研究,探讨了阻尼颗粒的碰撞耗能机理,根据理论分析中碰撞耗能以及摩擦耗能的结果,选择了减振效果佳且具有防爆功能的铜质颗粒作为本研究的阻尼器颗粒,设计了可安装于直径15mm细管的阻尼器。经对比减振前后振动加速度,安装该颗粒阻尼器后的减振效果达到38%,取得了较好的减振效果。

Abstract

The pressure gauge on the crude oil pipeline vibrates greatly and the pointer swings back and forth, resulting in inaccurate pressure readings. In response to the above issues, this paper adopted particle damping technology to conduct vibration reduction research on the pressure gauge and the thin tube below. The collision energy dissipation mechanism of damping particles was explored in this paper. Based on the results of collision energy dissipation and friction energy dissipation in theoretical analysis, copper particles with explosion-proof function and significant vibration reduction effect were selected as the damper particles. Moreover, a damper which can be installed on thin pipes with a diameter of 15mm was designed. After installing the particle damper, the vibration reduction effect of the thin tube reaches 38%.
