Designing an Ultra-low Specific Speed Centrifugal Pump
Traditional commercial centrifugal pump designs have specific speeds (Ns) greater than 500 because low values of Ns are usually associated with low efficiency, pulsation, and a drooping head characteristic. In this instance, acceptable hydraulic performance is achieved with a unique impeller design coupled with direct current (DC) motor characteristics. When the specific speed of a centrifugal ...
متن کاملImpeller and volute design and optimization of the centrifugal pump with low specific speed in order to extract performance curves
Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...
متن کاملOptimal Design Schemes of Centrifugal Pump Compound Impeller at Super-Low Specific Speed
The paper has established sixteen design schemes for super-low specific speed centrifugal pump compound impeller with orthogonal method, based on the main factors impacting the design of compound impeller, like short blades number of compound impeller, the relative position of blade radial inlet, blade circumferential bias degree, deflection angle, etc.,. By numerical simulation, the optimal de...
متن کاملInfluence of Tip Clearance on Pressure Fluctuation in Low Specific Speed Mixed-Flow Pump Passage
To explore the influence of tip clearance on pressure fluctuation in a low specific speed mixed-flow pump, tip clearances δ of 0.25 mm, 0.75 mm and 1.00 mm, along with no tip clearance, were selected. The reliability of the simulation was verified by comparison with the experimental data of external characteristics and fluctuation in the guide vane passage. Through ANSYS-CFX, MATLAB code and fa...
متن کاملOptimization and Analysis of Centrifugal Pump considering Fluid-Structure Interaction
This paper presents the optimization of vibrations of centrifugal pump considering fluid-structure interaction (FSI). A set of centrifugal pumps with various blade shapes were studied using FSI method, in order to investigate the transient vibration performance. The Kriging model, based on the results of the FSI simulations, was established to approximate the relationship between the geometrica...
