Application and Advantages of KOSUN Drilling Waste Decanter Centrifuge

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.

Advantages of KOSUN Drilling Waste 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.

The centrifuge is driven by two motors, master one and auxiliary one, of which the former and the latter drives screw propeller. After the machine is started up, the drilling fluids treated by desilter will be pumped to the narrow end of rotary drum via screw pump which will further push it into propeller. Then it will be thrust into the inner side of rotary drum via the holes of screw propeller by the high-speed rotation. At this moment, the rotary drum and the screw propeller will generate a 35:1 differential rotational speed as well as a centrifugal field where the solid phase will be rapidly separated from suspension due to their density and size differences. Then, the separated solids will move along the blocks of screw propeller to the narrow end of rotary drum and discharge from the round holes while the treated suspension to the broad end of rotary drum and discharge from elliptical holes of straight cylinder.
