Yesterday, I got an email from a lients who purchased of drilling fluid centrifuge last year and said the centrifuge working well and have no any spare parts to change until now, meanwhile attached two pictures.

The 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.

Typically,oilfield decanting centrifuge is the final processing units in the arrangement of solids control equipment. Decanting centrifuge preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud Cleaners (if utilized), Vacuum degassers and hyrdocyclones.

DCGLW series decanter centrifuge features and widely application

⋅ Leave a Comment

Centrifuges are used to process unweighted and weighted, water-based and oil-base drilling fluids. The DCGLW series centrifuge uses high G-forces to separate fine solids from liquids.

Mud is introduced in the feed chamber through a feed tube and exits in to the bowl via four nozzles. The DCGLW is able to exert up to 2,870 G’s on the mud. It has a fixed drive unit and has customized hardware and software packages that can be designed to meet specific installation and operation needs. With a processing capacity up to 200 gal/min the 3400 series centrifuge offers outstanding performance over a wide range of drilling applications and conditions.

Onshore or offshore drilling fluid centrifuge for sale

⋅ Leave a Comment

Centrifuge-evaluation procedures in common usage develop an efficiency rating expressed in percentage barite recovery and/or drilled-solid injection. DCLW Series decanter centrifuge can be used for onshore and offshore drilling site based on its good quality.

DC solids control produce 3 models of high speed,middle speed, variable speed 2 phase centrifuges that separate solids from liquids. In all three models, the operating principle is theoretically the same.

Decanter centrifuge

Besides above DC Solid control company has developed a wide range of decanting centrifuge equipment to provide optimal results. In weighted drilling fluid systems, decanters recover as much as 95% of heavy barite, which is returned to be re-used in the active system, while also removing finer, lower-gravity solids. By discarding lower-gravity solids our equipment is able to maintain a higher level of fluid consistency and help produce higher drilling efficiencies.

Please find more information on DC solids control site. Or you can contact us freely. DC provides the high quality solids control decanter centrifuge, also other equipment.

Main parts introduction for a decanter centrifuge

⋅ 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.

centrifuges

A decanter centrifuge is useful in that it separates solids and liquids, and has become an essential component of water waste facilities and the chemical, oil, and food processing industries. Moreover, without a centrifuge, many of these companies would become so inefficient they could not function.

 

1) Inlet zone

The inlet zone accelerates the feed slurry up to the speed of the bowl. A properly engineered inlet zone keeps any degradation of the feed solids to a minimum as well as avoiding disturbance of the sediment in the bowl. A number of feed zone specifications are available for decanter centrifuges, each designed to ensure maximum performance in conjunction with a specific process.

2) Screw conveyor

The key to good decanter performance lies in the efficient, effective scrolling of the sedimented solids. The design of the screw conveyor is therefore crucial. You must have the expertise needed to match the demands involved in specific industrial processes with specific configurations of flight pitch, lead angle and differential speed, in order to secure the best possible results.

3) Solids Discharge Section

Depending on the application, the consistency of the separated solids can vary from a dry powder to a paste. The configuration of the discharge zone is therefore chosen to enable such “cakes” to exit as effectively as possible. Innovative designs enables erosion-prone components used in the solids discharge zone to be replaced on site at low cost and with a minimum of disturbance to production.

4) Liquid Discharge Section

In a two-phase decanter, the liquid level is regulated by dam plates. In a three-phase centrifuge when operating in a three-phase mode, each phase discharges over a set of dam plates into separate baffled compartments in the casing.

A decanter centrifuge is useful in that it separates solids and liquids, and has become an essential component of water waste facilities and the chemical, oil, and food processing industries. Moreover, without a centrifuge, many of these companies would become so inefficient they could not function.

Decanter centrifuges

The principle behind a decanter centrifuge is based on the theory of gravitational separation. For example, if you fill a glass with a mixture of mud and water, over time the weight of the mud will cause it to settle down at the base of the glass. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two.

The ability to purify a liquid makes decanter centrifuges ideal for waste water treatment facilities. However, there are variety of industries for which such centrifuges play an important role.
