摘要: In centrifugal pumps, the interaction between rotating impeller blades and stationary diffuser vanes generates specific pressure fluctuation patterns. At off-design operation, high incidence large local gradients can lead to flow separations in or components of pumps. The resulting rise mechanical vibration levels may negatively affect operational performance life span components. This paper presents detailed measurements performed a speed pump stage at full scale domain various locations for different operating conditions.
