摘要
为提升地下储气库往复式压缩机的预防性维修和本质安全管理水平,用有限元分析方法分析压缩机。选取储气库压缩机关键部件——连杆、十字头和气阀为研究对象,以静力学分析和瞬态动力学分析的方法对其进行动态故障模拟。结果表明:随着储气库注气的不断进行,压缩机的负载逐渐增大,压缩机容易出现故障。压缩机中发生的单点故障,若未被及时发现和主动维修,其引起的振动将传递到其他零部件,加速其他零部件的退化,增加机组故障发生频率,并使压缩机整体性能下降,影响注采气效率。
For sake of improving preventive maintenance and inherent safety management of reciprocating compressors in underground natural gas storage, a finite element analysis of compressors was made. Dynamic failure simulations of crucial mobile components in reciprocating natural gas compressor were carried out. The results show that as gas injection continues, the operating load on compressor increases, the compressor becomes easy to break down. When single failure happens in a compressor and without timely repair, the vibration caused by failure transmits to other components, this phenomenon increases rate of component degradation and failure frequency of compressor, it also reduces performance and work efficiency of compressor.
