Constantes del controlador Las crecientes preocupaciones sobre el uso y la eficiencia de la energía han impulsado un uso más generalizado de sistemas de velocidad variable para impulsar bombas centrífugas. Hay varios factores en juego, pero la libertad de diseño que... by Troy Zellers | May 13, 2014 | The Pump Experts
In Part 1, we discussed the driving factors for increasing fluid temperature as flow is decreased through a centrifugal pump. For convenience, water was considered as the fluid in the examples given. Although water is the world’s most prevalent liquid, it’s also the... by Troy Zellers | Apr 15, 2014 | The Pump Experts
As discussed in the February article on Low Flow Concerns in Centrifugal Pumps, one of the motives for establishing a minimum continuous safe flow rate (commonly abbreviated as MCSF) is temperature rise in the fluid. There are several causes of efficiency losses in... by Troy Zellers | Mar 18, 2014 | The Pump Experts
The widely referenced centrifugal pump standard known as ASME B73.1 can trace its origins as early as 1955, when efforts to develop chemical pump standards began. This later evolved into the American Voluntary Standard in 1962 and, in conjunction with a similar... by Troy Zellers | Feb 18, 2014 | The Pump Experts
Centrifugal pumps are kinetic devices that continuously impart energy to the fluid passing thru it, nominally designed around a desired flow and head point called the Best Efficiency Point (BEP). Since the BEP is a specific point, it is unlikely to find an application...
