Värähtelyanalyysit

Värähtelyanalyysit, also known as vibration analysis, is a predictive maintenance technique used to monitor the condition of rotating machinery. It involves measuring and analyzing the vibrations produced by equipment such as pumps, motors, and turbines. These vibrations are a symptom of the internal health of the machinery. By understanding the patterns and characteristics of these vibrations, it is possible to detect early signs of developing faults before they lead to catastrophic failure.

The fundamental principle behind vibration analysis is that any mechanical defect, such as imbalance, misalignment, bearing wear, or looseness, will generate specific vibration frequencies. Specialized sensors, typically accelerometers, are attached to the machine casing to capture these vibrations. The collected data is then processed and analyzed using various software tools. This analysis can reveal the presence, type, and severity of a fault. Common analysis techniques include time domain analysis, frequency domain analysis (using Fourier Transforms), and spectral analysis.

The benefits of implementing vibration analysis are significant. It allows for scheduled maintenance interventions, reducing unexpected downtime and associated costs. It also improves safety by preventing sudden equipment failures. Furthermore, by identifying and addressing problems early, the lifespan of machinery can be extended. Vibration analysis is a cornerstone of modern condition monitoring programs across various industries, including manufacturing, power generation, and transportation.
