Drilling Mud Solution
LW drilling mud decanter centrifuges are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used frilling mud, including those based on water/synthetics and conventional oil-based drilling fluids.
Drilling muds are based on water, oil pr polymer with a composition of various additives such as flocculents, surfactants, detergents and more. By means of modern drilling mud system includes decanter centrifuge, cutting dryers, shakers, etc, everything brought into the mud by the frilling process will be separated. The clarified mud will be returned to the drilling rig
Working Principle
Separation takes place in the horizontal bowl equipped with a scroll conveyor. The drilling mud is feed into the bowl through a stationary inlet tube and is smoothly accelerated in the accelerate chamber. Centrifugal forces cause instant sedimentation of the solids on the wall of bowl. The conveyor rotates in the same direction as the bowl, but a different speed, thus moving the solids towards the conical end of the bowl.
Design Feature
Vertical base design and symmetrical arrangement of motor and bowl assembly, that ensures stable operation and less vibration.
Main parts such as the bowl and conveyor are made of corrosion-resistant stainless steel or duplex steel, offering high maximum bowl speed and high centrifugal force.
Solid Discharge Ports
Liquid Discharge Ports
Dual motor drive makes bowl speed and conveyor speed adjustable.
Optional planetary gearbox and hydraulic gearbox, offering wide range of differential speed adjustment
Multiple safety protection: bowl speed and differential speed detection, over-vibration protection, motor overload and overheat protection, bearing temperature monitoring, conveyor torque protection and gas-tight explosion-proof protection.
