Abstract

Proactive maintenance is a relatively new concept used today by the exploitation of manufacturing and energy production systems consisting of vibro acoustic monitoring of installations and equipment with professional equipment, such as Expret-Vibro and PROFISIGNAL software. These vibration level measurements are required for vibro acoustic diagnosis and for timely programming of repairs that are being challenged before accidental malfunctions occur. Electric steam turbines are used to produce electrical energy in refineries, which are particularly complex and are equipped with a turbine shaft located on several sliding or rolling bearings. Vibration sensors are mounted on bearing housings and are formed from one-axial, biaxial and three-axial accelerometers for absolute magnitudes (P-P and RMS speeds) or laser proximal sensors (relative and offset displacements). These sensors transmit the signals of data acquisition cards and amplifiers for data processing.
