VFD control panels (otherwise known as an AC drives, inverters or variable speed drives) are motor devices used for controlling AC motor speed and torque, achieved by changing input voltage and frequency in electrical systems.
These VFDs can be used in both small and large devices, however, they are most commonly used in larger machines such as compressors, conveyers, and drilling & pumping applications.
With that said, the VFD pump system panel is used for regulating and controlling the electric motor and feed pump speed, making pumping applications one of the most popular and fitting applications where VFDs are utilized.
But why are VFD panels a good choice for pumping applications?
There are many reasons why VFDs make a premier choice for pumping applications, including the following:
- Easy start/stop
- Adjustable speed
- High power factor
- Conserves energy
- Visual control
- IIoT and Predictive Maintenance (IIoT allows for the ability to constantly monitor conditions and parameters - meaning that technicians can track trends that could indicate the need for maintenance. They can therefore fix things before they break, minimizing downtime).
More on why VFDs so fitting for pumping applications:
- Variable torque application means a high potential for VFD savings
- Speed of motor or pump can be matched to the desired output, meaning less energy used, and higher VFD pump savings
- VFDs maintain the optimal speed required for an application to enhance production and save energy
- Low- and medium-voltage drives gradually accelerate and decelerate pumps - which can aid in keeping mechanical components safe while extending their lifespan and conserving power
Exploring the main components of VFD drives
There are four primary components in VFD drives: the rectifier, the intermediate circuit, the inverter, and the control unit.
Let’s talk a bit about each component below:
Rectifier: The rectifier changes the incoming alternating current (AC) to the direct current (DC).
Intermediate circuit: DC supply travels through this circuit using capacitors and inductors together.
Inverter: The inverter converts the DC supply from the intermediate circuit into the alternating current (AC).
Control unit: This is essentially the heart of the VFD, which monitors all operations.
Our team of experts recommends pump-dedicated VFDs as the optimal choice for pumping applications
When it comes to choosing a VFD for your pumping operations, VFDs created specifically for pumping applications are best.
For example, our team recommends Danfoss (VACON 100 flow) in particular for pumping applications, as it’s optimized for pumping in several critical ways. The Danfoss VACON 100 flow supports a fast and efficient system integration thanks to its dedicated functionality for pump, fan and compressor applications.
Furthermore, its specially-designed multi-pump solutions and application selection menus make it even more of a suitable choice. It also boasts an extended drive lifetime and minimized lifecycle costs due to electrolytic-free DC link capacitors.
