This paper investigates the application of vibration diagnostics in the maintenance of industrial facilities using an RCM (Reliability Centered Maintenance) strategy that increases efficiency and reliability. The research is based on continuous online monitoring and analysis of vibrations, followed by solving the issue of increased vibrations through the balancing fan, which result in improved efficiency and extended lifetime. The implementation of vibration diagnostics offers numerous benefits, but also challenges that are easily solved through the professional education. Additionally, this paper ensures the accuracy and repeatability of parameters using various scientific methods. Based on obtained results, the paper confirms the advantages of applying vibration diagnostics indicating its contribution in the detection and resolution of issues in modern industrial plant. The paper also makes a recommendation for further research, which includes expanding the use of vibration diagnostics to various types of industrial machines integrated with new technologies such as artificial intelligence and machine learning.
