往复压缩机管线振动原因识别方法综述

Introduction of Vibration Cause Identification Method for Reciprocating Compressor Pipeline

往复压缩机是石油化工、冶金等行业的关键设备之一,管线振动在压缩机工作中时有发生,管线剧烈振动严重影响安全生产,研究管道振动原因及其消除措施非常有必要。分析了引发压缩机管线振动3个主要原因以及相对应的消振措施,同时给出了管线的压力不均匀度、气柱固有频率、共振管长、管线固有频率的计算公式。分析引发管线振动的原因,最后得出了识别管线振动原因的方法。

Reciprocating compressor is a kind of key equipment in petrochemical and metallurgy industry.In the process of compressor operation,pipeline vibration occurred frequently,so it has a strong impact on safety production.It is very necessary to research the causes and the corresponding eliminates vibration methods.This paper firstly analyzed three main causes of compressor pipeline vibration and corresponding elimination vibration methods.Then computing formula for pipeline press heterogeneous degree,gas column′s natural frequency,resonance tube length and pipeline′s natural frequency was given.Finally,the methods of causing pipeline vibration were put forward and the method of indentifying pipeline vibration cause is obtained.
