Importancia del punto de mejor eficiencia (BEP)

Entendiendo los factores involucrados para determinar el desempeño de la bomba

Cuando trabaje con bombas, seguramente encontrará instancias en las que se hace referencia a la curva de la bomba, junto con una serie de parámetros asociados con ella. Un parámetro clave de la curva de la bomba es el Punto de Mejor Eficiencia (BEP). Este concepto simple de un punto de operación que produce la operación más eficiente no es difícil de visualizar. Para motores eléctricos, la eficiencia varía con la carga; la mejor eficiencia está en alrededor del 75% de carga. Sin embargo, con las bombas rotodinámicas, que incluyen bombas centrífugas y de flujo axial, hay que considerar cuatro parámetros clave, uno de los cuales es la eficiencia. Estos cuatro parámetros son cabeza, caudal (también conocido como capacidad o volumen), potencia y eficiencia.

EASA explains upcoming pump standards

New requirements in 2020 offer opportunities for improving system function

Starting in January 2020, the U.S. Department of Energy (DOE) will begin implementing the first ever energy efficiency standards for freshwater rotodynamic (centrifugal and axial flow) pumps. These standards will directly affect pump manufacturers and, to a lesser extent, the pump repair market, while ultimately benefiting end users if the new focus can reduce their energy costs.

Preparing for the new focus on pumps and pump systems

Everyone is probably familiar with the impact of energy efficiency efforts on our industry. For electric motors, this has been both a concern and an incentive for innovation. EASA members and manufacturers have been shaped by the governmental and market forces aimed at reducing electrical energy usage. Electric motors are a primary target of these “green” efforts.

But the commercial and regulatory landscape is ever evolving, and the horizon coming into view includes a new focus on pumps and pump systems. The U.S. Department of Energy (DOE) is implementing efficiency standards for rotodynamic pumps (centrifugal and axial flow pumps). The standards will have little effect on the pump repair market, while pump manufacturers are directly affected. But pump efficiency is very different from electric motor efficiency.

Probablemente todo el mundo se encuentra familiarizado con el impacto de los esfuerzos de la eficiencia energética en nuestra industria. Esto ha sido una preocupación y un incentivo para la innovación en los motores eléctricos. Los miembros de EASA y los fabricantes han sido moldeados por las fuerzas gubernamentales y del mercado, destinadas a reducir el uso de la energía eléctrica. Los motores eléctricos son un objetivo primordial de estos esfuerzos "verdes".

Pero el panorama comercial y regulatorio se encuentra en constante evolución y el horizonte que se vislumbra incluye un nuevo enfoque para las bombas y los sistemas de bombeo.

Fundamentals of Pump Repair

Book

The repair of the various types of pumps represents an important segment of the service center repair market. Electric motors and pumps are the two most widely used industrial machine components.                                                                                                                                                                                                                       

Although there are two principle pump types (dynamic and positive displacement), this manual focuses on dynamic pumps and the fundamentals of dynamic pump repair. The information it contains will be helpful to both novice and experienced pump repair technicians, to supervisors and managers of pump repair operations, and to customer service and sales personnel who communicate with customers about pump repair issues.

Importance of Best Efficiency Point (BEP)

Understanding factors involved in determining a pump's performance

When working with pumps, you are sure to encounter instances where the pump curve is referenced, along with a number of parameters associated with it. A key parameter of the pump curve is the Best Efficiency Point (BEP). This simple concept of an operating point that yields the most efficient operation is not difficult to visualize. For electric motors, efficiency varies with load; the best efficiency being at about 75% load. However, with rotodynamic pumps - which include centrifugal and axial flow pumps - there are four key parameters to be considered, one of which is efficiency. These four parameters are head, flow (aka capacity or volume), power and efficiency.
