In order to ensure failure tolerance of a process system it is necessary to monitor the equipment degradation, diagnose and control the equipment condition by giving the personnel notifications concerning urgent immediate actions.
Reliability and service life of the units depend heavily on their vibration; and vibration, in turn, is determined by the errors in manufacture, assemblage, repair and mounting at the unit as well as by operational defects caused by wear, mistakes of maintenance personnel and faults of operating conditions of the unit. That determines the necessity of vibration analysis of equipment condition at all stages of its life-cycle: for evaluation of workmanship, repair and mounting at the unit, for evaluation of technical condition in operation due to wear, mistakes of maintenance personnel and violation of operating conditions of the unit.
During vibration analysis of even one process unit diagnostic information should be collected, processed, presented and transmitted to the personnel in appropriate form during short interval of time (5-10 minutes) determined on the one hand by the maximum speed of malfunction development, and on the other hand – by the necessity of timely detection of mistakes or negligence of maintenance personnel and violation of operating practices which causes the unit failure. Considerable information scope requires the use of only stationary systems for continuous vibration monitoring.
