Manufacturers and operators produce, purchase and use better motors with regulated testing.
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.
Price, operating costs and reliability are key factors in any TCO calculation.
The best option for preventing bearing currents depends on the source of the problem.
The updated regulations may require machine redesign and premium efficiency motors and components.
These are the details of the snowmaking machines used during the Winter Olympics in Sochi, Russia.
Price, operating costs and reliability are key factors in any TCO calculation.
Guidelines for reduced vibration and information on how a pump’s foundation and operating speed affect the vibration response
Ease of installation, improved algorithms, enhanced displays, onboard communication and other technology make VFDs an ideal and cost-effective solution.
