Decanting centrifuge is mode of KOSUN,they are ideal choices for separating particles in drilling mud. 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. Under the influence of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the nud export of the small end of the drum and excreted. But the fluids is excreted from the overflow hole of the large end. Such cycle is in order to achieve the purpose of continuous separation.High speed decanting centrifuge are effective for separation
The centrifuge of series LW is driven by two motors. The main motor drives the drum and outer casing of differential through the belt. And the auxiliary motor, after shifting gears by the differential, will drive spiral propeller, which will make the drum and the spiral propeller rotate in the same direction with revolution difference possessed to some extent.
And when the material is fed into the inner canister of the spiral propeller from the feed pipe, the material will be flowing to the drum wall through material exit. The degree phase of the material is different because it is subjected to different centrifugal force and so, the material with heavy phase will be quickly accumulated onto the inner wall of drum while the material with light phase will slowly stick to the surface of heavy phase, a layer of interface to be formed between degree phases. And along with increase of heavy phase accumulation, the top end of spiral vanes will be inserted into the accumulated layer of heavy phase. By this step, the drum and spiral impeller are rotating with high speed in the same direction, having differential speed value to some extent. And the relative revolution difference is making grain of heavy phase move to the material exit on the small end while the liquid of light phase is forming into passage, flowing to the exit of liquid phase. The overflowing mouth position of liquid phase is controlled by the regulating plate.
When decanting centrifuge is used in solids control,it is the last equipments of the solids control system,there are other solids control equipments are combined with it,such as shale shaker, desander, desilter, mud cleaner, vacuum degasser,decanter centrifuge, submersible slurry pump,shear pump,centrifugal pump,mud agitator, mud gun, shale shaker screen,jet mud mixer,mud tank,etc.This all products KOSUN can manufacture,also,KOSUN provides oilfield services.
