Features of Decanting centrifuge supply from China supplier

Decanting centrifuge separate the suspending fluids using the principle of centrifugal action, the suspending fluids is pushed into the rotor drum through the inlet pipe and the fluid hole of the spiral feeder. As a solid control equipment, drilling fluid centrifuge plays an important role in drilling operations

In the centrifugal separations of drilling fluid, screw conveyor is a critical component to push and separate the sediment. The work performance and structural parameters of conveyor are immediately related to the production capability, the working life and the separating effect of the centrifuge.

Drilling fluid decanter centrifuge used for oil gas drilling

Decanting centrifuge is also referred to centrifuge decanter, or decanter centrifuge. Centrifuges are used to process unweighted and weighted, water-based and oil-base drilling fluids.  DC Machinery is a manufacturer on drilling fluids decanter centrifuge for many years.

drilling fluid centrifuge

Centrifuge used in drilling solids control is the decanter type. Almost the decanter centrifuge used at drilling site are horizontal type. There are bowl, drum, conveyor, motor, control panel consisted in centrifuge assembly. Of course, also the support base or base frame.

oilfield centrifuge

Decanting centrifuge in drilling fluids system is used after desilter cone or mud cleaner. It can handle the solids ranged 2-7 microns. There are middle speed and the high speed one, the fixed frequency or VFD one. Treating capacity / handling rate varies along with centrifuge size. Usually, it is from 30~60m³/h. We can select screw pump or slurry pump as feeding pump.

Our Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (mud). 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.

If you have request with the decanter centrifuges, please contact me freely.

Oilfield use decanter centrifuges shipped to Russian

Decanter Centrifuge is designed for the drilling mud solids control and oilfield waste management. DC VFD drive decanter centrifuge with variable speed allows drilling contract or mud service company to do the barite recovery, fine/ ultra fine solids separation,dewatering centrifuge.

Today, DC Solid control shipped 3 sets of oilfield decanter centrifuge for a Russian drilling contract. The centrifuges are the fixed frequency type, and the max drum rotary speed is 2800rpm, max treating capacity is about 45m3.

Decanting centrifuge key part is screw conveyor and transmission. When centrifuge work, drilling fluid will flow into centrifuge through drilling fluid input. Then the roll bowl will increase speed and fluid will flow into centrifuge through one fixed input pipe. Since rolling bowl rotate at rather high speed.

decanter centrifuges

Drilling mud decanter centrifuge are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used drilling mud, including those based on water/synthetics and conventional oil-based drilling fluids. If you have interest with all industries, please feel free to contact us.

DCLW series decanter centrifuge features and extensive application

DCLW series decanter centrifuge uses solid-liquid density difference to form two-phase separation under the function of centrifugal force. It’s mainly for the recovery of barite, removing fine solids and reducing the solids content of drilling fluid, controlling the density and viscosity of the drilling fluid, ensuring the performance of the drilling fluid, and having an important role in rapid drilling.

Drilling fluid centrifuge for Unweighted and Weighted Drilling Fluids.

Drilling fluid centrofuge is the 4 stage equipment of the oil& gas drilling fluid circulating system. The centrifuge suck the mud from the compartment receiving the discharge from the desilters and mud cleaners, and the returned stream is directed to the next compartment downstream.

DCLW centrifuges can be used in Unweighted Drilling Fluids and Weighted Drilling Fluids. Following is the maters of the centrifuge used in the different materials.

decanter centrifuges

When centrifuging the unweighted drilling mud, keep in mind the following:  the centrifuge with High G force as the solids loads are low. Adjust the weir to a deep pool to maximized solids separation. Control a smaller mud feed rate to increase residence time Operate centrifuges in parallel, not in series if multiple centrifuges are required.

With the unavoidably higher solids content of weighted mud, the increase of gel strengths and viscosity, as well as the degradation of ? quality associated with the diminution of particle size with time, can become a serious problem. The problem is caused by the increasing concentration of colloidal and near-colloidal particles that are  to be separated from the base. Centrifuges are used to selectively remove these solids.

With high solids content of weighted fluids, torque is a problem when processing it, the following is some advice when operating the centrifuges. Increase pond depth. Reduce in rpm or run a higher conveyor differential. Process the mud at a reduced feed rate Centrifuges.

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.
