In recent trends, the industry is shifting from preventive maintenance to predictive maintenance. It essentially involves the human perception and a mixture of complex instruments to check the machine while it is running. Vibration analysis is one of the most effective tools for checking the condition of factory machinery and diagnosing the cause. By using conventional instruments for regular or continuous vibration monitoring to check the operating conditions of the machine, this can enable you to find faults as early as possible and take countermeasures to avoid catastrophic failures. In this article, I studied the common causes of vibration in rotating machinery. Each mechanical problem produces a specific spectral pattern, and these problems can be identified through frequency and phase analysis. Here, I have explained the frequency analysis, phase analysis, unbalance and balance process in detail. The vibration measurement and data acquisition equipment and acceptance criteria are also discussed. The different case studies I conducted in different industries included balance issues, misalignment issues and resonance. We eliminated them by balancing, cross-coupling alignment and dynamic shock absorbers. In a case study, we used vibration analysis to determine the location of the CMM machine.
