This paper explores the principles of vibrodiagnostics, focusing on how vibration indicators like amplitude, frequency, and phase can reveal common pump problems such as unbalance, misalignment, cavitation, bearing wear, and loose parts. The use of spectrum analysis and time domain analysis for diagnosing specific faults is discussed. The article highlights how vibrodiagnostics enables proactive maintenance strategies, reducing downtime, improving efficiency, and minimizing maintenance costs. Case studies and examples showcase the practical applications of vibrodiagnostics in ensuring pump reliability and promoting safe operations. By adopting vibrodiagnostic programs, industries can significantly enhance the performance and longevity of their pump units, leading to improved overall productivity and profitability.
