USE OF TRANSDUCERS IN MEASUREMENTS OF ROTORS SYSTEMS

摘要

The perspective of employment to diagnose quality of functioning of rotor system and discovery of developmenting defects of vibrationing signals, which registrate in the work of rotor system is important for properties of strengthening vibrotransducers, for simplicity of fastening of noncontact lasering speed and for inductive measuring transducers of improvement. It is examine the diagnostic system in this work, in which apply a few contact and noncontact transducers (frame of rotor vibroacceleration, inductive measuring transducers of improvements, laser measuring transducer of speeds and measuring transducers of phase). It is investigate the rotor system in which can be assemble hydrodynamic bearings and bearings of rolling of different construction. The object of research in the base of diagnostic measuring is to ascertain characteristics of inside sources, which cannot get in method of direct measuring. The quality of ability to work of this system belongs from type of using transducers and from apportunitys of analyses of getting signals. Orbits of rotor center, spectrums, densitys and others statistic characteristics are given using computering system of diagnosing of rotor systems according to which we can decide about technical state of rotor system.
