Working principle of the centrifugal: Drilling fluid enter the hollow shaft in the spiral conveyor by the feeding tubes, then flow into the barrates. Because of the high speed rotating of the barrate, to drive the entered drilling fluid rotating together, the solid phase in the drilling fluid is thrown the wall of the barrate, the drilling fluid expel from the screw conveyor pushing to the discharge hole of the small port. The choice of centrifugal by the particles size of separation solid phase, the barrate,diameter of centrifugal, the highest speed and the separation factors influence, the drilling site commonly used the solid and liquid density difference, as the separation basic of the settlement centrifugal, mainly clear the solid phase substance in the drilling fluid, is the last level of drilling fluid solid control equipment.
