Motors
Motors are the most common source of power used by pumping systems. This technology is heavily regulated. Pumps by themselves are not variable speed, an option that many systems need to operate with peaks and ebbs during the run cycle, such as power generation. The addition of a variable frequency drive (VFD) gives it that capability.
Digital variable reluctance technology could result in positive changes in the efficiency and power of pumps.
Many of these factors relate to the ongoing instability in various parts of Europe, but in today’s interconnected global economy, innumerable current events and trends can impact the marketplace.
Bundling technologies leads to enhanced system efficiency for a Connecticut water supply.
Michael Michaud, executive director of the Hydraulic Institute, spoke with Pumps & Systems about how end users can prepare for new Department of Energy rules and policies.
The facility’s variable speed electro-mechanical drive offered a compact, convenient solution that was energy-efficient.
The retrofit saves the facility several thousand dollars per year.
DOE rules since 1992 have impacted the U.S. motor market.
End users must consider many variables to choose the better solution.
This method of achieving variable speed pumping promotes energy efficiency and can pay for itself over a long period of service.
When following the new DOE guidelines, don’t forget these considerations.
Evaluating system requirements and all available options can improve reliability, efficiency and cost.
Achieving unity power factor through the use of synchronous condensers can be a win-win situation for power utilities and consumers.
The study will give industry stakeholders a better understanding of the marketplace and help them become more globally competitive.
This alternative technology is ideal for petrochemical applications.
Drives with active energy control can save energy and extend motor life for pumping and HVAC loads.
Today’s innovations in drive technology and design offer powerful benefits even beyond energy savings.
