Detect cavitation in centrifugal hydraulic pumps: A Review

Abstract

Centrifugal pumps play an important role in engineering applications due to their wide use in both industrial and domestic systems and their versatility in handling a wide range of flow rates. However, the turbomachinery of these pumps often exhibit cavitation and irregular turbulent flow, and their performance can be difficult to improve. Cavitation is a complex phenomenon that reduces the efficiency and performance of centrifugal pumps. It is one of the most common causes of pump performance degradation. The severity of cavitation and its diagnosis affect pump reliability. This study reviews several experimental methods and control systems produced so far and highlights the area of future research on the topic of cavitation to extend pump operating life, save maintenance costs, and improve pump reliability. The results show that cavitation detection is possible, but in order To improve the reliability of the pump, a large number of sensors should be used to increase data accuracy, along with advanced data processing software. Additionally, methods of redundancy and double-checking should be applied, as well as leveraging modern artificial intelligence techniques for early detection.
