DCLW Decanter centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and the spiral propeller rotate in the same direction with a certain differential speed.

decanters

Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system.oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.

The characteristics of Decanter centrifuge by DC

:1. Innovative design includes longer bowl, allowing drilling fluids to thread through more slowly, thus resulting in drier solids and finer separation point;
2. Big bowl offers big volume. It also generates high-G force;
3. Stainless steel bowl, scroll, compartment are available and covered with corrosion-proof coating so as to have longer lifespan;
4. Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maximum solids control efficiency.
5. German FAG or Swedish SKF brand bearings are available;
6. Electrical Components complies with SIEMENS/Schneider ATEX or IEC Ex.

The main specification as below:

Drum dia:450mm

Treating capacity: 45m3/h
Main Power: 22kw
Back Power: 11kw

The Operation Principle of Drilling Mud Decanter Centrifuge

The drilling fluid decanting 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 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 circle like above to achieve the target of continuous solid-liquid separation.

DCLW decanter centrifuge adopts centrifugal force to separate solid particles out of drilling fluid.Different solid or particle have different density and flow speed,some decanter centrifuge also can separate particles as different size
and density DCLW decanter centrifuge is widely used in oil and gas drilling,chemical,foodstuff,pharmacy,mineral beneficiation,water treatment,etc.

Five crucial factors determine the performance of decanter centrifuges

⋅ Leave a Comment

In order to fully understand how a decanter centrifuge operates, we must first define what a centrifuge does. In many industrial jobs, solid material often mixes with liquids, contaminating water supplies or turning mud into sludge.

Do you know what factors determine the performance of decanter centrifuges ? Please carefully read as below.
1.the centrifugal force required for sedimentation of the solids
2.the clarification area necessary to “capture” the solids
3.the differential speed required to transport the solids out of the decanter
4.the hydrodynamic design, which determines the exact parameters for the turbulence
5.the design of the conveyor and beach sections, which are important for efficient solids transportation.
