... Abstract Torque is one of the most important operating parameters of centrifugal pumps which reflects the internal flow rate of centrifugal pumps. In order to explore the unsteady characteristics of torque of centrifugal pumps based on sensorless monitoring technology, a series of accurate...

... Abstract The residual axial thrust of a centrifugal pump is the vector resultant of the hydraulic components of impellers and sleeves, the momentum force and other imbalance forces and is bear by the thrust bearing. Among all the components, the hydraulic is by far the most important because...

... With the widely application of IS series centrifugal pumps in industry and agriculture, the blade-passing frequency (BPF) flow-induced noise in these pumps are tend to be optimized. In this paper, a common type IS50-65-160 is chosen as the model pump to do the optimization of BPF noise. Considering both...
