Impeller 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 کاملMethod of Evaluation of Efficiency Improvement Potential for District Heating Systems with Focus on Variable Speed Centrifugal Pumps
The goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. The effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. This is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...
متن کاملDesigning 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 کاملOn the centrifugal pumps performance curves estimation using empirical equations
A group of empirical equations were developed in order to estimate the performance curves (H Q, n Q, P -Q, NPSHr -Q) of a centrifugal pump, using quite small amount of pumps geometric data. The results of the present study prove that centrifugal pumps performance curves direct estimation could be accomplished without using complex mathematical models. Furthermore more, all-basic parameters affe...
