VIBRATION CONTROL IN RECIPROCATING COMPRESSOR SYSTEMS
Reciprocating compressors inherently generate pulsations in the compressor cylinders and attached piping system. The reciprocating motion of such compressors, along with the pulsations they generate, result in mechanical vibrations. Pulsations and vibrations can adversely affect the compressor performance, increase maintenance costs, and ultimately result in unavailability of equipment. For systems with unacceptable pulsations and/or vibrations, design modifications should be considered to reduce the risk of failures and improve reliability by reducing the pulsation and vibration to acceptable levels. This short course will discuss the fundamentals associated with pulsation and vibration problems in reciprocating compressor piping systems. The course will cover areas of good general practice to control vibration and will illustrate several troubleshooting will be discussed. Topics from the GMRC Systems Mounting Guidelines for Separable Reciprocating Compressors in Pipeline Service document and guidelines for compressor foundation design will also be discussed. This short course will improve the attendees ability to identify potential problems in new designs and to have a better understanding of existing vibration problems.
