Desilter is the third class solid control equipment to treat the drilling fluids. That is a centrifugal device for removing very fine particles, or silt, from drilling fluids to keep the amount of solids in the fluid at the lowest possible point. Usually, the lower the solids content of mud, the faster is the rate of penetration.
Desilter is designed by the theory of particle sedimentation. The separation medium-drilling fluid produces some pressure and speed when it passes the centrifugal pump, and flows into the hydrocyclone along the wall, the bigger solid particles along the wall of hydrocyclone sink spirally under the centrifugal force and gravity, and to be discharged from the bottom flow hole and fall on the under micromeshsieve for separation. The other mediums rise along the spiral of hydrocyclone, flow into the fourth class separation equipment-centrifuge for a further cleaning treatment from the overflow hole.
Hydrocylone Desilter separators are one of the important equipment of controlling the solids in the drill fluid. The action is to remove the harmful solids, promote the drill fluid performance and separate 15～45 μm solids particles accounting for over 60﹪ of solids quantity.When the quick drilling is made in the soft formation, the shale shaker only can remove large solids particles, but the Hydrocylone Desilter separators can remove fine solids particles, fully promoting the solids control efficiency. Therefore, it is especially suitable for the well site where the formation is considerable hard and the drilling speed is slower so that the cuttings is very fine in particle size.
Except,KOSUN supplies other solids control equipments,including shale shaker, shale shaker screen, desander, desilter, vacuum degasser, centrifugal pump, submersible slurry pump, shear pump,mud agitator, mud gun, drilling fluid mud cleaner, decanter centrifuge, jet mud mixer, mud tank, diesel tank, water tank, etc.
