Case Study on Resolving Cyclic Vibration on an Instrument Air Compressor Train

Case StudyInstrument Air Compressors are considered critical equipment in the plants, supplying compressed air to the instrumentations in the field. This case study focuses on cyclic vibration phenomena observed in the 2nd and 3rd stages of an Instrument Air Compressor, part of an Integral Gear Compressor train driven by a motor. The machine train is equipped with an online vibration monitoring and protection system with online diagnosis software, which was used to diagnose the phenomena & forward path for the resolution
