How to design VFD Control Panel for Decanter Centrifuge

The drilling mud decanter centrifuge driven by VFD will give many benefits to the clients. The adjustable bowl speed and differential speed allows the operators to set the right G force and solids pushing speed according to the drilling mud conditions.

To design the VFD Control Panel, the contractor needs the power supply specifications. Normally it is 460V/60HZ for USA standard or 380V/50HZ for Europe and China standard. Than the pulley size of the motor and bowl side will decide the bowl driving speed at different frequency. After confirming the bowl speed formula, the contractor needs the formula for calculation of the differential speed. For GN Decanter centrifuge, the Sun-Wheel gear box ration is 57:1. So the differential speed will be the bowl speed minus the gearbox input speed and divided by 57.

For the VFD Control panel, there is different explosion proof standard. In China, it is CN Explosion proof which is close to IEC Ex standard. In Europe, it is ATEX Explosion proof. And in North America, the explosion proof standard is UL for USA, and CSA for Canada.

GN Pressurized VFD Decanter Centrifuge control panel is specially design for Zone 1 or Zone 2 standard with ABB VFD and stainless steel cabinet. The PLC smart control allows the user to operate the drilling mud decanter centrifuge by HMI screen.

GN VFD decanter centrifuge has been exported to over 30 countries and regions, GN Solids Control VFD decanter centrifuge is available in different sizes including: GNLW223C-VFD (9inch) bowl, GNLW363C-VFD(14inch bowl), GNLW453C-VFD (18inch bowl), and the big bowl big volume centrifuge with 22inch bowl and model is GNLW553C-VFD.
