Centrifugal pumps energy efficiency examining influential parameters contribution

Energy consumption around the world is the one the most important topics that researches and industrial sector make great effort to improve mechanical systems efficiency. Currently, energy efficiency enhancement strategies are widely applied all around the world as the crucial approaches to improve energy consumption. Pumps and air conditioning systems have remarkable contribution to the world electricity consumption that in the meantime pumps accounts for nearly 21% total consumption. According to the conducted literature, the level of the design accuracy in particular impeller as the heart of the pump, coupling system, electromotor and pump compatibility considering the operating conditions and piping system, and applied manufacturing processes as well as constructions materials. Simulation and modeling system can highly be an effective approach in early steps of design to examine whole system to be prepared for any circumstance. Even well-designed pump could work under bed operating conditions. This paper aims to provide insight into advanced characteristic modeling methods, and energy efficiency enhancement regulation to improve pumping systems. A comprehensive summary of traditional methods and advanced regulation methods have been proposed to shed lights on the relevant issues for future research.
