Design and Analysis on Hydraulic Model of The Ultra -low Specific-speed Centrifugal Pump

The Super-low specific-speed centrifugal pump has been used widely in most industrial fields of petroleum, chemical industry, aviation, pharmaceutical industry, metallurgy, etc. With the development of the petrochemical industry and the space technology, the lower ultra high speed centrifugal pump is gradually developed, its speed is much higher and the flow rate is much lower than the low-specific speed centrifugal pump [1,2]. Based on the foundation of the former researcher, I have designed and developed GSB20-380 hydraulic model of the ultra-low specific-speed centrifugal pump. In order to rich the achievements on the ultra-low specific-speed centrifugal pump in theory, CFD(Computational Fluid Dynamics)numerical simulation and performance tests were adopted to study the model of the centrifugal pumps, to analysis the hydraulic properties of the ultra-low specific-speed centrifugal pump.
