Centrifuge uses high-G force to separate fine solids from liquid. It can be used to process weighted and unweighted, oil based and water based drilling mud. Popular centrifuge manufacturer like Derrick, Swaco and NOV brandt are US brand. Here introduce a China popular brand, GN Solids Control.

GNLW363VFD

Let’s compare GN Solids with NOV Brandt centrifuge hereunder:

1. NOV Brandt centrifuge, HS-2171L centrifuge

The HS-2172L centrifuge is fed from the solids end of the conveyor. Mud is introduced into the feed chamber of the HS-2172L through a feed tube and, with the aid of a concave accelerator, exits through twelve (12) nozzles into the bowl.

The HS-2172L is equipped with variable frequency drive (VFD) control, which provides a controlled application of motor drive power to the centrifuge components (bowl, conveyor and feed pump). Customized hardware and software packages can be designed to meet specific installation and operational requirements. With a processing capacity of up to 550 gal/min (2082 lit/min), the HS-2172 series centrifuge is able to quickly process high volumes of mud while allowing prescribed mud weights and separation efficiency to be maintained. This enables the HS-2172 series centrifuge to produce fine cut points at higher flow rates, making it ideal for high-flow applications and critical-conditions solids control.

Classified by drive mode, Decanting Centrifuge has different models, like hydraulic drive, electric drive and also magnetic drive. Different drive model has different advantages and disadvantages. Hydraulic drive centrifuge can be started very smoothly, with less noise and less friction. But once some problems arise, it is very hard to maintenance. Electric drive is not that smooth when starting, but is easier for maintenance for trouble shooting, so that lead to less cost.

Some remarks:

FHD: Full Hydraulic Drive ; VFD: Variable Frequency Drive;  Magna: Magnetic Drive
