SS304 Automation Drilling Mud Decanter Centrifuge For Civil Engineering Industry

Purification Equipment Drilling Mud Centrifuge For Oil Gas Engineering Industry With High Quality

Decanter centrifuge is the 4th solids control equipment or the 5th purification equipment. Including middle speed and high-speed centrifuges. It is used after desilter or mud cleaner. We use a submersible slurry pump or screw pump to transfer drilling mud from desilter compartment to the centrifuge.

decanter differential speed automatic control technology can automatically adjust the screw conveyor’s differential speed, to prevent overload and blockage. The complete machine is equipped with a bearing temperature sensor and vibration sensor and is provided with alarms for main motor overload, differential over-torque, low differential speed, etc. Meanwhile, its supporting frequency conversion (flameproof) control cabinet can realize automatic start and stop with one key.

Centrifuges used in zero discharge mud system is to get rid of rather a little solid in drilling fluid. To maximize drilling fluid liquid content recirculation and minimize solid disposal

Compared to previous solids control equipment, centrifuge remove fine cuttings or recycle barite with 2~7 microns diameter. The material for centrifuge including S.S304, 316, 316L, 2205, and so on. Per clients' demand and their budget we'll configure different products

Decanter centrifuge is the 4th solids control equipment in whole drilling mud system It is used to process drilling mud discharged from desilter cones or mud cleaner

Technical parameters 

Some configurations can be customized according to the customer's actual demands

The series of the centrifuge by our company has been developed many years with the continuous improvement and optimization design, which possesses the characteristics of a good result of separation and settlement, as well as large quantity, reliable work, longer life, lower energy consumption, easy maintenance, smooth operation, lower noises, etc.

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

To meet the requirements of the development of modern drilling engineering, GREEN developed and equipped with the explosion-proof variable frequency control system which could adjust separation factor and drum rotational speed. This new technology, make the centrifuge adapt to property changing of mud during the operation process, which makes the treatment more effective and perfect.

A VFD ( Variable Frequency Drive ) module monitors and controls both the main and back electric drives. The operator can manage bowl and scroll speeds via a touchscreen that also displays input from the various sensors, including temperature, current, rotational speed, and vibration.

Professional of Aipu solids control

As a professional manufacturer of oilfield solids control equipment, AIPU products are appreciated by clients because of their high quality at a reasonable cost. Trust AIPU solids control will be your strong assistance. Our solutions for you and your clients will be the optimal ones and lead to more reasonable profits. AIPU products have served KDC, Burgan, SINOPEC, CNPC, Honghua, Petronas, Pertamina, and so on drilling companies and rig manufacturers.

Characteristics of drilling fluid centrifuge

The straight section and the cone section of the drum are made of 2205 bidirectional stainless steel and are made by centrifugal casting.
The rest of the drum assembly is made of SS316L stainless steel.
The screw pusher is protected by a wear-resistant alloy sheet, which has a long service life and is easy to maintain and replace.
The shunting port of the screw pusher and the slag discharge port of the rotating drum is protected by an easy-to-replace wear-resistant alloy sleeve, which delays the service life and maintenance cycle.
The convenient and adjustable height of the cofferdam can meet the discharge requirements of different working conditions. Original imported SKF bearings can improve equipment stability and bearing service life.

Decanter Centrifuge Main Component

Rotating parts including centrifuge bowl and screw for stainless steel material. The screw impeller is coated with tungsten carbide for protection of impeller wear. The most popular size bowl is 355mm in diameter and 1250mm in length for a maximum rotating speed of 3500RPM.

Main motor and assistant motor installed to drive centrifuge bowl and screw for flameproof standard.

The electrical control panel is the same explosion-proof standard compared with the centrifuge motor. The VFD control panel can be supplied for various speed control depending on mud conditions.

Centrifuge skid with legs to install bowl, motor, and control panel.

Other than a decanter centrifuge, AIPU is able to supply complete solids control equipment and tank equipment like a centrifugal pump, mud agitator, mud gun, and degasser. The whole tank design and pipeline arrangement are customized as per request.

Drilling mud decanter centrifuge for drilling fluids

Decanter centrifuges 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 is able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, -forces separate fine solids from liquid.

Another application of the Aipu decanter centrifuge

As we introduced before, centrifuges can be used not only in the drilling fluids process. They can be used in many industries. Related to oil and gas industry or the drilling industry, they can be used in slurry separation, sludge treatment, waste management, and so on.
And in drilling fluids systems, they are used to recycle or reclaim the barite, too. When we use both middle-speed centrifuge and high-speed centrifuge, the high-speed one will be set behind the middle speed one.

Advantage of Aipu drilling mud decanter centrifuge

All raw materials are high quality. Such as the screw conveyor, bowl, support frame, surface paint, the motor, the control panel, etc. 

Usually, finishing one set centrifuge may take 30 days. But now, only in 1 week we’ll get all things cleared and make it arrive at the port. For other requirements or options, we’ll give you the optimal solution soonest.

Finally, our aftermarket will definitely satisfy you on soon response as 7×24 technique support. The centrifuge is rather mature to save more cost on wearing parts as well as maintenance
