The drilling fluid decanter centrifuge is driven by two motors for drilling mud system

KOSUN drilling fluid decanter centrifuge is driven by two motors. The main motor drives the drum and reducer case rotate by the belts. The vice motor drives the spiral through the reducer. The drum and spiral rotate together for the same direction, and produce some difference of speed. Separate the solid phases in the drilling mud by the centrifugal sedimentation principle. The drilling mud flows into the drum from the fluid hole through the inlet pipe and under the force of screw pusher, under the effect of centrifugal force, the solid phases will be pushed onto the inside wall of the drum, pass the impeller on the screw pusher and be discharged from the exhaust hole at the small side of the drum. The liquid phase will flow out from the big side. The drilling fluid re-circles like above to achieve the target of continuous separation.

Decanter Centrifuge can effectively remove the harmful solid particles from the oil and gas drilling fluid, improve the mud performance, ensure the drilling safety, lessen the pollution of oil/gas reservoir and reduce the mechanical abrasion of drilling equipment. 1650-2200 rpm centrifuge can separate 2-7μm solid particles.

Working Principle:

Mixing with the acceleration phase: the material into the mix and get into the correctly predicted to accelerate, to ensure that the best state of the material into the separation zone.

Clarify the stage: the role of the centrifugal, the materials in the drum line segments rapid separation and sedimentation, the supernatant was separated in the drum weir discharge port.

Compression stage: the propeller will be sent to the discharge side of solid deposition, the material under the action of the centrifugal force can be further compressed, and the release of pore water.

Compression in the right section: the drum section of the cone, the material produced by the specially designed biaxial compression, screw conveyor family properly designed, produced along the axis of extrusion pressure.
