Decanter centrifuge is utilized to remove solids in oilfield drilling operation to achieve drilling fluids purification. Decanter centrifuge is also named as horizontal screw discharge or decanting centrifuge, and is the special solids control equipment to conduct liquid separation. It is normally applied as fourth stage equipment; the first stage is shale shaker, then desander and desilter. Desander, desilter and shale shaker are in one unit for the mud cleaner.

The swirling centrifugal force from its electric motor accelerates solid sedimentation and separates different sedimentation coefficients and buoyant densities. Then its thruster pushes the slags out since differential mechanism occasions a speed difference between screw thruster and bowl, carrying settled solids off the bowl and down to the narrow end along screw blades, dewatering them at the meantime and then thrusting them out from discharge nozzle.
 

Six Steps to Install Drilling Fluids Decanter Centrifuge:

1. Drilling decanter centrifuge ought to sit far from the inlet of mud pump for a full agitation in the mud.

2. Firm installation of drilling 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 decanter centrifuges for the sake of repairing safety.
