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 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 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 کاملDesign and Performance Analysis of Centrifugal Pump
This paper deals with the design and performance analysis of centrifugal pump. In this paper, centrifugal pump is analyzed by using a single-stage end suction centrifugal pump. Two main components of a centrifugal pump are the impeller and the casing. The impeller is a rotating component and the casing is a stationary component. In centrifugal pump, water enters axially through the impeller eye...
متن کاملCentrifugal pump failures.
Centrifugal pumps will not pass gross quantities of gaseous emboli due to the nonocclusive nature of the pump. However, retrograde flow can occur under circumstances that include: product malfunctions, low flows, and human errors. Negative pressure created by falling arterial perfusate can draw air into the cannula. Food and Drug Administration (FDA) records about centrifugal pump malfunctions ...
