Drilling mud decanter centrifuge is 4th phase solids control equipment for drilling fluids. It is one of the most important devices in drilling mud system, it mainly separates particles out of drilling mud over 2μm.

The drilling fluids decanter centrifuge is driven by two motors. The main motor drives the drum and differential shell rotation by the belt. The vice motor drives the spiral through the differential variable speed. The drum and spiral rotate together in the same direction, but at different speeds. Separate the solid phases in the drilling mud by the centrifugal sedimentation principle. Suspending fluids is pushed in the drilling mud by the centrifugal sedimentation principle. Suspending fluids is pushed into the rotor drum through the inlet pipe and under the force of screw propeller, 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 propeller and be discharged from the exhaust hole at the small side of the drum. The fluids is excreted from the overflow hole of the large end. So continuous solid-liquid separation.
 

The Distinctive Characteristics of KOSUN Drilling Fluids Decanter Centrifuge

1. Can operate at full speed to finish feeding, centrifugal sedimentation discharge and other procedures, high degree of automation.

2. Optimized the settling parameters and feeding mode, enhanced the centrifuge sand removing effect, performance can be comparable to the same specifications of the imported centrifuge.

3. Horizontal spiral unloading settlement centrifuge vibration are low noise. By improving the accuracy of both centrifuge rotational part machining and dynamic balance, the centrifuge vibration and noise dropped to a low level.

4. The production capacity of the single machine is large, the structure compact, occupation small, and it can automatically run, is convenient to maintain and can be closed operation.

5. Simplified solids control system, low energy consumption, lighter working load, and the purification efficiency increased by 30% than original.

6. Uses the frequency conversion governor, compared with similar products with low energy consumption, working speed is adjustable, etc.

KOSUN is worth the name of the leader and professional in the oil drilling mud solids control in China, we have obtained industry experience over 20 years, the solids control equipment KOSUN can provide for the oilfield include shale shaker, shale shaker screen, desander, desilter, vacuum degasser, centrifugal pump, mud agitator, drilling fluids mud cleaner, decanter centrifuge, jet mud mixer, mud tank, complete solids control system and many kinds of oilfield services, etc.
