Abstract

In an industrial environment, a large part of the solutions used in machine parks is based on rotating systems. Therefore, the branches of diagnostics in this area are subjected to extensive research so that they effect with more and more new solutions. This article presents the problem of selected most common faults in a low-speed machinery environment. Presented chapters define the concept of symptoms and diagnostics and define its goals. Selected issues of the analysis of diagnostic signals were also discussed.

Highlights

  • Slow-speed rotating machines are the basis of operating in many production branches all around the world

  • Diagnostic research is aimed at determining the state of a technical object, the process at the moment considered important for a particular research

  • The aim of technical diagnostics is to determine the condition of a technical object by means of direct tests of their properties as well as indirect examination of the accompanying processes, the so-called residual processes

Summary

Low speed rotating machinery

Slow-speed rotating machines are the basis of operating in many production branches all around the world. Defects can develop very slowly until they are revealed (to a noticeable failure) it is only possible to apply corrective measures not preventive ones [3] Moving elements of these machines, such as bearings, gears, rotors, gears of shafts, which are subjected to degradation over time, require sustained monitoring. Diagnostic research is aimed at determining the state of a technical object, the process at the moment considered important for a particular research. The use of technical diagnostics methods at each stage of the machine operation and analysis of the generated signals determines their condition. This allows you to anticipate the necessary inspections and repairs. The essence of model-supported diagnostics is to compare the results of observation of a working device with the results of its operation simulated by a model [4, 9]
