abstract

The intention of this paper is to demonstrate the advantages and the economic benefits of vibration root cause analysis and diagnosis, proper treatment of rotors during service outage, and follow up after commissioning of the units versus the general industry approach of field balance all vibration problems. During the course of the paper several diagnostic tools and repair procedures will be introduced and discussed. Special enfaces is made in the identification and treatment of rotor’s bows, misalignments, and eccentricities since they represent the most common and less recognized vibration root cause. A case study will be used as a guide to facilitate the comprehension and to illustrate real industry results that can be achieved by systematically following the proposed methodology.
