Price, operating costs and reliability are key factors in any TCO calculation.
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.
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.
The construction, seals and protective monitoring contribute to the motor’s ability to operate in and under water.
Use a mathematical model that estimates vibration at the top bearing of a motor used on a vertical, wet-pit, column type pump.
Advanced VFD technology delivers cost and space savings by providing protective features and minimal programming.
A dewatering facility brings a centrifuge up to speed slowly, meeting the long acceleration time requirement.
A VFD and a permanent magnet, direct-drive motor replace a gearbox, reduce maintenance costs and provide energy savings.
Using variable frequency drives provides many benefits to end users.
Repetitive motor failures may be caused by a lack of diagnostic or forensic repair information reported to the motor owner.
A variable frequency drive’s effect on system efficiency and motor life
End users must include bearing clearance as an integral part of designing or building a pump.
A strong safety program and preventive equipment are crucial for operator and equipment safety.
Make the ideal motor selection for irrigation applications.
Equipment and technology improvements can be sound investments.
In the food industry, stainless steel performs more productively and efficiently.
A simple mathematical model can be used to estimate vibration at the top of the motor in a vertical pump-motor structure.
