400V Variable Frequency AC VFD Drives for Decanter Centrifuge

Decanter centrifuges are used to extract (dewater) solid materials from liquids when they are mixed together in slurry. Decanter centrifuges are used in many industrial applications such as:
1. Oil /solids separation (oil well drilling, refining, de-watering)
2. Industrial and biological wastewater treatment
3. Food processing (olive oil, wine, fruit juice)
4. Fish processing (fish meal, fish oil)
5. Chemical slurry
A main drive motor supplies power to turn the centrifuge. AC drives are commonly used to power the main drive motor. There are several different types of decanter centrifuges, such as: Vertical, horizontal, or scroll (conveyor).

Application Challenges

· Minimize the need for gears or belts to drive the centrifuge.

· Control and maintain speed during the decanting process

· Develop high torque at very low speeds.

· Two motor applications, one for the bowl and one for the scroll.

· The bowl has a very high-reflected inertia.

· The scroll is usually in continuous regeneration, as it runs at a slower speed than the bowl and is pulled along.

· Torque limiting on the scroll is very important.

· Some configurations require zero-speed operation of the scroll (differential gearbox).

· Dynamic braking or regenerative modules may be required if the bowl is NOT driven by a drive.

Features of G7 series matching decanter centrifuge application

Features	Benefits
Frequency Detection Speed Agree	Both Frequency Detection and Speed Agree signals can interlock with primary and auxiliary machinery as well as safety equipment while the machine is operating.
Overtorque or Undertorque Detection	It is possible to notify the user of an impending fault before it occurs based on the Overtorque or Undertorque Detection settings.
Multi-Step Frequency Reference	Analog inputs are not required due to 17 possible Multi-Step Speeds. Operating speed can be adjusted for optimum performance.
Dwell Function Stall Prevention Feed Forward Function	For accelerating high inertia loads, the user can increase the Dwell Function setting and tune Stall Prevention. The Feed Forward function can also be used to assist in acceleration.
DC Injection Braking High Slip Braking	Although the stop time is generally long due to a large inertia moment, it is still possible to quickly stop the drive without a braking resistor by using the DC Braking or the High Slip Braking function.
Accel/Decel Times Intelligent Stall Prevention	Fast acceleration and deceleration times are possible by adjusting Accel/Decel times and using Intelligent Stall Prevention. This can reduce overall process time.
Fault Restart	The drive can automatically start after being shut off by using the Fault Restart function.
Flux Vector Motor Control	Provides high starting torque and good speed regulation.
Standard Motor Used	Standard NEMA B design motor can be used to eliminate specially designed motors.
Energy Saving Mode	Energy saving operation can be implemented at full speed during light loads.
