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.
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.
Regardless of whether you need to keep a pump parameter constant by adjusting the pump speed, or adapt to a varying pump demand over time, VFD operation brings benefits aplenty. Let’s take a look at a few examples.
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.
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.
3 sty 2024 · Variable Frequency Drives (VFDs) have become a game-changer in the world of pump systems. They offer a way to control the speed of pumps, leading to significant energy savings and improved system performance.
From demanding residential to agricultural and commercial applications, Franklin Electric’s variable frequency drives provide an easy-to-install constant pressure solution and built-in protection for a variety of jobs.
