Application KOSUN mud agitator is part of the drilling fluids solids control equipment ,which is mainly used to agitate and mix the drilling mud to prevent solid particles settlement in circulating tank. Mud agitator is composed of explosion–proof motor, speed reducer, motor base and blade.The connections between motor and speed reducer, speeder reducer and impeller shaft by steel coupling.The impeller is welded by four blades. Structure Mud agitator mainly consists of explosion-proof motor, reducer, motor base and impeller assembly, solid couplings are used to join motor with reducer, and reducer with impeller shaft. Four vanes are installed and welded to form the impeller. Working Principle The impeller makes the fluid in vortex motion and improves the agitation effect. The pallet among the vanes can prevent solid particles in mud from depositing around the lower vanes after shutdown, which reduces the moment of resistance of deposits agai...

Vacuum Degasser Application     Gases are entrained in drilling fluid from the wellbore during normal drilling operation as well as during "kick" or well control situations, these gases present safety hazards and create operational problems, in case of the presence of hazardous gases, it is desirable to localize the point where gas is released from the mud by installing a vacuum degasser . Features & Advantages 1. Absorbing the waste gas with its own power unit independently, without the extra centrifugal pump 2. Can be worked as high power drilling mud agitator 3. Eliminating the corrosion for the solid control equipment, reducing the cost for the maintenance 4. Compact design, saving space Mud Gas Separator Application The field-proven KOSUN mud gas separator is an extremely reliable and vital piece of safety equipment for today drilling operations. It is ideal for use where drilling is likely to encounter large volumes...

  KOSUN high effective mud cleaner is the second or third stage s olids control system equipment of drilling mud , which will deal with the drilling   mud after being treated by the first stage s olids control system equipment. The barite will be recovered and drilling cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the shaker screens when the weighted mud passes while the particles that are bigger than mesh will be removed.   KOSUN desander is used as the second  stage of solids control system for drilling mud, which makes separations between 40 and 100 microns.   KOSUN desilter is used as the thir d stage of solids control system for drilling mud, which make separations between 15 and 44 microns. 1. Polyurethane (PU) Material for desander and desilter cones. 2. Desander cones can be installed between one and three 10 ” desander cones, each cone can process 5...

S hale shakers typically consist of wire mesh  shaker screens  in various mesh sizes that shake or vibrate the drill cuttings which across and off the shaker screens as the drilling fluid or drilling mud flows through shaker screen s  and back into the drilling mud system.  There are mainly three types of shaker screens for different types of shale shakers, like PWP screen, PMD screen, and hook strip screen. PMD screens are Derrick ’ s patented products for Derrick 2000 series and Derrick 500 series shale shakers . While PWP and hook strip screens are widely used for world famous shale shakers like brand M-I SWACO, Derrick, Brandt and KOSUN. Hook strip s creen s  is a  common kind of s hale s haker s   s creen, which can be widely used in different conditions in drilling operation. This screen is constructed with two  or three layers of stainless steel wire cloths bonded to a steel...

Linear motion shale shaker  is  the  first stage  solids control equipment in drilling fluid   processing system, well  known as solids treating  equipment in solids control system . Linear motion shale shaker  decides the performance of the whole solids control system . Linear motion shale shaker  for solids control system   remove s  dril l  cuttings from drilling fluid during   mud circulat ion  and drilling.  Controlling the solids in drilling fluid is important to control  drilling  cost and protect environment. Linear m otion s hale s haker s typically consist of wire mesh shaker screens in  various mesh sizes that shake or vibrate the drill cuttings  which across and off the screens as the drilling fluid or drilling mud flows through shaker screen  and back into the drilling mud  system. This separates the solid drill cuttings from the fluid so that it can be recircu...

Separation of solids and fluid  is completed   within the  drum. Its principle is high-speed rotating drum drive inner mud rotate speedily  then  the mud is thrown onto drum’s surface  to make  a fluid circle. Under the centrifugal force, solid sedimentary force in the separated liquid will be several hundred even thousands of times heavier than its own gravity so as to separate the solids from the suspension quickly. The ratio of centrifugal force which the solids have gained and the solid’s gravity is called as separating factor. The larger the centrifugal force, the finer the separated solids, so three types of centrifuge can get according to separating factor. Hydraulic Coupler Operation Principle Hydraulic coupler mounted on main motor, it is a hydrodynamic transmission device, have the function of buffering starting shock, reduce starting current and overload protection .  It consists of shell, turbine, pump wheel, input shaft, output p...

Application D ecanter centrifuge is used in separating suspension of solid phase with 2～70% solid concentration, liquid viscosity ≤0.01PaS, particle diameter d≥2μm, in clarifying suspensions with little solids as well as amorphous material that brings difficulties for filtering cloth regeneration and suspensions which have a big change range in solid phase concentration. T he d ecanter centrifuge is also used in the solid-liquid separation  in the fields of oil & gas industry , chemical industry, food, pharmacy and environmental protection, carrying out dehydration of solid phase, liquid clarifying, liquid-liquid-solid separating, granularity grading and other separating processes. Structure DC series horizontal decanter centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and t...

Drilling mud is employed to regulate subsurface pressures, lubricate the drilling bit, stabilize the well bore, and carry the drill solid cuttings to the surface, among alternative functions. Drill mud is pumped-up from the surface through the hollow drill string, exits through nozzles within the drilling bit, and returns to the surface through the ring-shaped   area between the drill string and also the walls of the outlet. As the drilling bit grinds rocks into drill cuttings, these drill cuttings become entrained within the mud flow and area unitcarried to the surface. so as to come the mud to the recirculating mud system and to create the drill solids easier to handle, the drill solids  should be separated from the mud. the primary step in separating the drill cuttings from the mud involves current the mixt...
