KOSUN Drilling Decanter Centrifuge is Used in Drilling Mud System

As is well-known, drilling mud is the blood of oil drilling system, and it is very precious. The drilling mud solids control system can effectively separate the large drilling cuttings, barite and other large solid particles contained in the drilling mud returned to the ground from well. The treated drilling mud can be used repeatedly. The role of drilling mud solids control is to treat and recycle the drilling mud returned to the ground from well with solids control system or some solids control equipment, so as to reduce the drilling cost and protect environment.

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.

To ensure that the effective treatment result and long service life, the important parts adopts high quality stainless steel, forging material, strengthen heat treatment and strict control processing. And on each part that easily wear take spraying wear-resisting layer and mosaic of hard alloy etc. The overflow of the main drum mouth using adjustable poling board, it can be adjusted anytime according to different sludge treatment.

The mud separation process between solid phase and liquid phase is completed in the roller. 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.
