Analysis and Treatment of Vibration Fault Occurred in Labyrinth Reciprocating Compressor Used in Polypropylene Plant

The phenomenon of vibration fault occurred in early imported labyrinth reciprocating compressor was introduced. Combined with the experience in the management of procurement for main equipment used in petrochemical plant and from the respects of centering of shaft system of compressor set,gas pulsation,equilibrium of inertia force and moment and loosing cement base,the cause of vibration was analyzed.Then,the source inducing this vibration was determined and relevant measures were carried out,so that the hidden risk to normal operation of machine was avoided and the guard for safe,stable,long term and satisfied performance was provided.
