Decenter centrifuge as the fourth stage solids control equipment is used after desilter or mud cleaner. It is also an important part of mud purification system. Decanter centrifuge is mainly used to retrieve barite, clear fine solids, decrease solid content of drilling fluid, control drilling mud density and performance. It will have obvious effect especially used in oilfield service industry, industrial service and environmentally sensitive areas.

Decenter centrifuge function

Decenter centrifuge is installed the last stage of solids control system to process unweighted and weighted, water-based and oil-based drilling fluids. Oilfield decanter centrifuges increase the gravitational force exerted on the liquid and solids mixture present in the mud system. Centrifuges can apply over 3,000 G-forces to separate heavier solids from the lighter solids.

Aipu decanter centrifuge can meet custom’s different requirements for drilling mud processing. Centrifuge can sedimentate and separate more than 2μm suspended solids. Furthermore, it is an ideal equipment for processing waste drilling mud to prevent the pollution of the environment.

The types for centrifuge

According to different rotating speed

1. High speed centrifuge
2. Middle speed centrifuge.
3. Fixed speed centrifuge
4. VFD centrifuge decanter

Usually, the VFD centrifuge decanter is the high speed type. Since VFD panel will help to start centrifuge softly and

The advantage of Aipu centrifuge

1. High degree of automation. The centrifuge can be fed and discharged continuously. Under the action of the centrifugal force, the solids are discharged to spiral drum continuously.
2. Good degritting effect. With constant development and innovation for centrifuge and after repeating test, optimized the settling zone parameters and feeding method, enhanced the degritting effect of centrifuge, performance can be comparable to the same specifications of the imported centrifuge.
3. Low consumption on energy and light working load. Handing capacity increased 30% than the original, but power does not increase. Furthermore, the motor load is no more than 80% of the rated power.
4. Reliable work, a long service life. Bearings are world famous FAG or SKF ensure high quality and high performance. Drum and screw are made of high quality 304 or 316L ensures a long usable life. The discharge output welded by tungsten as anti-corrosive layer assure more durable.
5. Low noise, small vibration. Enhanced the machining precision and dynamic balance precision of drilling mud centrifuge rotation part.
6. Compact structure, a few spare parts, easy to install and maintain.
7. Adopt the frequency conversion governor, compared with similar products, it has low power consumption, the working speed is adjustable.
