| Abstract: | With the installation in petrochemical industry tends of maximization, the problems of flow pulsation and pipeline vibration in reciprocating compressor have been the key of influencing overall performance. This paper has specified the hazard of flow pulsation and pipeline vibration and its producing mechanism, analysis method, steps and technique, and control measures. The application of DIGMO and CAESAR II analysis software are pointed out to comprehensively analyze the vibration in compressor pipeline. The purpose of expected verification for product quality in design stage is realized. It can also analyze the vibration problems of online equipment. Futhermore, the rectification program is given. |
