Separation Principle of KOSUN DC Series Oilfield Drilling Fluids Decanter Centrifuge

Drilling decanter centrifuge separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of centrifugal force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.

Advantages of KOSUN Drilling Decanter Centrifuge

1.Longer bowl: it adopts innovative longer bowl, allowing drilling fluids to stay longer within bowl in order to get finer solids and separation point.

2.Corrosion-proof and wear-resisting bowl made from alloy materials. Snap-on hard alloy sleeves are fixed at the sediment outfall of taper cylinder.

3.Corrosion-proof and wear-resisting spiral propeller is welded with a layer of wearable tungsten carbide on the residue discharge surface,which is polished to smoothness.

4.The machine also contains bearings manufactured by German FAG and Swedish SKF which comply with SIEMENS/Schneider ATEX or IEC Ex.

5.KOSUN Decanter Centrifuge matched with international brand feed pump,which has been specifically designed to provide a quick and easy way to disassemble,de-rag and maintain a Progressive Cavity Pump in-situ,eliminating the costly maintenance and down time that servicing can often cause.

KOSUN DC series oilfield drilling fluids decanter centrifuge is used in drilling mud system for separating suspension of solids phase with particle diameter（d≥2μm） for drilling mud circulation and drilling fluids recycling. Ruggedly built for oilfield and industrial services, drilling mud centrifuge is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The oil drilling mud decanting centrifuge must test the dynamic balance for smooth operation over long periods. Speed ranging from 0 to 3900 RPM, generating centrifugal forces reach up to 3000G.

KOSUN has always been well accepted by domestic and overseas customers with its high quality and performance products and high standard after-sales services. As a high-end brand of KOSUN, Black Rhino Series products are great achievements of excellent design, research and development by KOSUN’s technical team, including Shale Shakers, cleaners, centrifuge and other solids control euqipment. Meanwhile, this series of products have passed long-term field test in USA. After each performance meets American users’ requirements,  they are rapidly promoted at home and abroad and have won users’ favor.
