DC models drilling fluid centrifuge in drilling site

Drilling fluid centrifuge is an important part of solid control system. DC Solid control sold 50 more sets centrifuge to different countries used for different industries.

Drilling rig centrifuges have got large development on both structure and functions. Especially there are many manufacturers design centrifuges according to drilling mud features or property. Then the centrifuge become many models and types used in various drilling projects.

drilling fluid centrifuge

Decanters are equipped with either fixed or variable back drive. The scrolling speed -(relative conveyor speed) can be changed in a matter of seconds by operations of a simple control switch. The optimum scowling speed is selected in each case according to solids load, required separation efficiency and required underflow density.

Actually, in drilling rig solids control system centrifuge is the most complicated one. It is rather difficult for operator get leagal operation, etc. However, in long term its important position is following shale shaker subsequently.

 

Key benefit of oilfield centrifuge from DC Mud equipment company

An oilfield centrifuge is one of solid control equipment which has a capability to remove solid which is larger than 10 micron.The oilfield centrifuges have limitations on feed rate, solid discharge, power of motor, etc. Therefore, it cannot handle the entire solid in the mud.

mud equipmentThe best way is to place shale shakers and/or hydrocyclones upstream of the centrifuges in order to remove large solid particles and let the centrifuges remove large portion of small particles which cannot be separated by shale shakers and hydrocyclones. By doing that, you will be able to effectively eliminate both large and small particles.

Key Benefits of DC Mud centrifuge 
Simple, compact and robust design
High efficiency in removing fine solids
Automatic, unattended operation
Low operating cost and easy maintenance
Reliability and long service life
Extremely versatile – can be used with all mud types

DC Mud equipment company has many models centrifuges are available for customer option, customized centrifuge could be designed and provided as per customer requirements.

 

Complementary use of hydrocyclones and centrifuges

DC Machinery offers solutions for all of your Classification needs from hydrocyclones and centrifuges to classifiers and heavy media separation.

Hydrocyclones are related to centrifuges in that both are intended to separate heavies and lights by application of centrifugal force. The key difference is that hydrocyclones are passive separators capable of applying modest amounts of centrifugal force, whereas centrifuges are dynamic, spinning separators that are generally able to apply much more centrifugal force than hydrocyclones.

Another key difference between hydrocyclones and centrifuges is cost. Centrifuges are expensive precision rotating machines that often need sophisticated control, whereas hydrocyclones have no moving parts and usually no controls at all, so they are lower cost devices.

hydrocyclones

Hydrocyclones and centrifuges are complementary rather than competing devices. If gravity alone will settle a significant portion of your solids in a minute or two using a quick bottle test, you should investigate hydrocyclone separation. If settling takes much longer than this, then you may need a centrifuge or other separation method.

Large stock of DCLW355-1258VFD Centrifuges enjoy discount sales

Simplified solid control system, DCLW centrifuges with the advantages of low energy consumption , lighter working load, and the purification efficiency increased by 30% than original.

 

Advantages of using decanter centrifuge for oilfield

Having effective solids control equipment is very important for any oilfield. Without having proper solids control, drills can encounter a variety of problems.

With a horizontal oilfield decanter centrifuge, the mixture of drilling liquid and cuttings and solids enter into the centrifuge. When it enters the centrifuge, it gets spun at an extremely high rate, sometimes as much as 3000 times the force of gravity. When this happens, the solids will separate from the liquids. When they are separated, the drilling liquid can be decanted and eventually returned to the mud tank where it can be replaced into the borehole for efficient drilling.

One of the biggest advantages to having an oilfield decanter centrifuge is the size that it takes up. Compared to other solids control equipment, a centrifuge takes up less real estate. On many oilfields the site footprint is not large enough to support a wide range of solids control equipment. A centrifuge is highly effective and efficient so you can separate solids from drilling liquids even on small drilling sites.

Small flow decanter centrifuge for waster water processing

Sludge dewatering is the separation of a liquid and solid phase whereby, generally, the least possible residual moisture is required in the solid phase and the lowest possible solid particle residues are required in the separated liquid phase.

DCLW Small flow decanter centrifuge is a professional unit for waster water processing unit. DC Machinery can supply treating capacity from 3-10m3/h samll flow decanter centrifuge.

In this case, the residual moisture in the dewatered solids determines the disposal costs and the centrate quality determines the pollution load returned back to the treatment facility. Minimizing both must be achieved at the lowest possible cost, with the lowest possible polymer and energy consumption, with low maintenance costs and with the lowest possible number of required operating staff.

In practice, the operator quickly realizes that there is no clearly defined operating point given daily and seasonal fluctuations; changes in system input or process configurations, as well as malfunctions of every sort always present new challenges that must be met.

The DCLW model decanter centrifuge is a highly engineered piece of process equipment designed to separate insoluble suspended solids from a liquid. The centrifuge can be used to produce a relatively dry cake from the separated solids and are flexible enough to cope with a wide fluctuation in the feed material and still achieve excellent clarification and dewatering performance.
