Vibration diagnostics of rotary equipment is one of the reliable methods for preventing accidents and predicting equipment life. This article will discuss the theoretical principles of the impeller’s fan bearings spectral analysis of vibration, as well as the method practical application.

This article provides a way to detect fatigue cracks in welded gearwheel at reinforcement dimensional cutting mechanism (flying shears) of rolling mill by analyzing the direct spectrum of vibration. This method is progressive and allows through regular vibration measurements to assess equipment condition and predict performance.

The methods of remote vibration diagnostics realization of metal-rolling department’s equipment will be considered in the article, and also the example of the really set system is resulted. Application of this system allows not only exposing the state of workings parts of mechanism presently, but also carrying out the prognosis of equipment’s working capacity.
