Vibration Analysis and Control of Compressor Outlet Piping System
摘要
Abstract
The outlet piping system installed downstream of reciprocating compressor is subjected to abnormal vibra-tion,which greatly exceeds the allowable limits of the API 618 standard.Based on on-site vibration testing and resonance analysis,it was found that this vibration problem was caused by excessive pressure pulsation in the piping system.To miti-gate the pressure pulsation induced forces,a vibration control scheme increasing the diameter of the T-junction was pro-posed.The flow field characteristics and fluid-structure interaction(FSI)response of the original outlet piping system and the proposed modified outlet piping system were studied using numerical simulation software ANSYS.The results indicated that the maximum flow velocity at the T-junction is lowered by 45%,the pressure unevenness is reduced by 24.4%,the tur-bulent kinetic energy is dissipated by 96.3%,and maximum deformation is lowered by 28.7%in the proposed modified out-let piping system.With the implementation of the proposed modified outlet piping system,the maximum operating speed of the compressor increases from 850 to 920 r/min,the vibration velocity at the dangerous point in outlet piping system is re-duced by 57.1%,all vibration levels of the system are below the API 618 limits.It is concluded that the vibration control scheme enhanced the safety and stability of the compressor operation.关键词
