Decanter centrifuge is one of the equipment in solids control system on oil field. There used to be 3 overload safety protection on KOSUN DC Series centrifuge. One is the safety protection device of the gear box, second is the hydraulic coupler overload protection, third is the control panel with over currency protection. Nowadays as we change the drilling centrifuge structure there are 2 protections. One is hydraulic coupler overload protection to protect the bowl and the other is control panel protection to protect the screw conveyor.
Decanter centrifuge is used in many industrial applications such as: Oil /solids separation,Industrial and biological wastewater treatment, food processing,Fish processing, Chemical slurry.The decanting centrifuge slurry is fed through a stationary pipe, which is inside a hollow shaft connected to a screw conveyor or scroll.The slurry enters a feed compartment located inside of the conveyor and is forced through discharge nozzles to the bowl section.Once inside the bowl, centrifugal force causes the material to separate.The screw conveyor moves the solids to the tapered end where they are discharged.Clear fluid flows out the other end.Some decanter centrifuges are powered by a motor and gearbox combination. The gearbox provided the correct speed and torque to drive the solid control centrifuge.
KOSUN DC series decanter centrifuge is used in separating suspension of solids phase with particle diameter（d≥2μm） for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas.Drilling mud decanter centrifuge, in which there is no physical separation between the solid and liquid phase, rather an accelerated settling due to centrifugal acceleration.With all the mentioned features, KOSUN decanter centrifuge can meet with different requirements of mud treatment for various industry.

Six Steps to Install Drilling Fluids Decanter Centrifuge
Decanter centrifuge is really one of the most useful machines, because it has found wide application in many industries. The commonest industries include oil well drilling, biological wastewater treatment, food processing, chemical slurry and other fields. It is used to extract particles from liquids.
KOSUN Drilling Mud Decanter Centrifuge efficiently removes undesirable solids from drilling mud in crude oil extraction. The decanting centrifuges 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.
Six Steps to Install Drilling Fluids Decanter Centrifuge:
1. Drilling solids decanter centrifuge ought to sit far from the inlet of mud pump for a full agitation in the mud.
2. Firm installation of drilling solids decanter centrifuge is important, so its 4 legs ought to be fixed on the surface of tanks with bearing bars.
3. Its installation also involves protruding the discharge groove from the tanks and connecting it with hydraulic supply line for a better performance of sand discharge.
4. Mud pump ought to stand behind desander and desilter, and connect tightly with feed pipes and inlet pipes.
5. Join together the flushing feed pipes and perforated pipes on inlet pipes and the tank.
6. Plug in and switch on all the parts of drilling solids decanter centrifuges for the sake of repairing safety.
Much current centrifuge application with drilling fluids is not only unproductive, but is counterproductive. One example of misuse is the practice of running two centrifuges in parallel to "recover the barite" with the first and "discard the drilled solids" with the second. The first stage is traditional centrifuging, returning the underflow to the active mud system. Rather than discarding the overflow, it is routed to the second centrifuge running at a higher speed, where the low-gravity solids supposedly are discarded and the "clean" liquid is returned to the mud.
