Novel method for detecting cavitation in centrifugal pump with frequency converter
In this article, a novel method for detecting cavitation in a centrifugal pump with a frequency converter is proposed. The method is based on the frequency converter's estimates for the rotational speed and shaft torque of the pump. The method has been tested in the laboratory with two different pumping systems and the obtained results are presented. Test results show that high flow cavitation can be detected by the proposed method.
