Variable frequency drives are widely used on pumps and machine tool drives, compressors and in ventilations systems for large buildings. Variable frequency drive motors on fans save energy by allowing the volume of air moved to match the system demand.
23 wrz 2024 · When using a VSD with a deep-well pump (vertical turbine or submersible) in a sandy well over 200 feet in depth, maintaining a minimum vertical (i.e., uphole) velocity of 2.5 FPS is necessary to prevent the settling of sand into the upper pump stages.
10 sie 2018 · In the majority of applications, pairing a pump motor with a VFD provides a pump curve that exactly matches the pump operating point the system requires at any time, controlling the flow without wasting energy or sacrificing efficiency.
28 cze 2017 · When considering the relationship of variable frequency drives (VFDs) with well water applications and the efficiencies they bring, a measure of success depends on the working definition of the word “efficiency.”
28 lis 2011 · While modern VFD’s provide a much higher level of monitoring and protection for your system, drives cannot make up for a poorly selected motor and pump combination. Solid system design and an up-front investment is money well spent when installing a pressure controlled water system.
22 maj 2023 · Based on 28 reviews. Watson Well variable frequency drives for well pumps save you money by varying motor speeds to match your water demands.
Whether surface water or groundwater is used for water production, Danfoss AC drives (or VFD pumps) can help optimize the process and reduce energy and maintenance costs. A typical application is the control of deep well pumps, where the integrated advanced minimum speed monitor secures sufficient lubrication to protect the pump.
