what is the decanter centrifuge?

Pay attention to LW series decanter centrifuge operation
1. The sedimentation centrifuge of horizontal and helix unloading is a kind of equipment with high rotating speed. And to operate the centrifuge with more effectiveness, the instructions must be carefully read before starting the machine.
2. LW series centrifuge has bigger rotating inertia and the current to start. It can last for a longer time. So, the circuit and electric equipment should be able to be running with bigger load.
3. Before the centrifuge is solidly installed, it is forbidden to operate the equipment..
4. While operating the centrifuge, the holding down bolt of the machine housing should be screwed down.
5. If there is apparent and abnormal noise and vibration in operating the centrifuge, the equipment should be immediately halted. Before the equipment is stably halted, it is strictly prohibited knocking down the machine.
6. While using cleaning liquid to wash the drum and spiral impeller, the cleaning liquid is not eroding drum and spiral impeller should be used.
7. When the centrifuge is not used, the power supply to the main and auxiliary motors should be turned off.
8. For maintenance and repairing the rotating parts including the drum and spiral impeller, if welding and polishing have to be used, please contact the KOSUN company.
9. It is strictly prohibited to knock down the drum and the differential, not to mention exchanging the position between the drums or exchanging the position with drum of other centrifuge.
10. If the machine is not used, it should be guaranteed that the drum be prevented from being in contact with corrosive medium. (Before stopping the machine, wash it with clean water or cleaning liquid of50℃.)

KOSUN is one of the professional solids control equipment manufacturers

As we all know that drilling fluids are used in the drilling process to keep the drill bit cool & carry the down hole drilling cuttings up to the surface of the well. To maintain the specified viscosity and density of the drilling fluids, some drilling fluids agents such as barite, bentonite, etc. must be added into the fluids in the drilling process. Previously centrifuge are used to add these fluids agents into the drilling fluids, but now mud mixer or some called mud hopper are used specially to complete the adding processing in the solids control system.

Jet mud mixer is composed of single mixer & double mixer. The electrical motor drives the drilling fluids flowing in the pipeline, and fluids agents are added through the hopper into the drilling fluids. It enhances the shearing rate to the fluids agents, and reduce the viscosity time of the drilling fluids. KOSUN series mud mixer is used to make and mix drilling fluid to change the density and viscosity. This device can satisfy the fluid weighting and mixing of solids control system for 1500m-9000m drilling.

Below is the illustration of mud hopper. The design of mud hopper is with venturi & jet. When the drilling fluids flow through the jet, the pressure of venturi would be lower than the standard air pressure, so the drilling fluids agents in the hopper would enter into the venturi automatically, and dissolve into the fluids with the fluids flowing.

Technical Features: 1. Can be worked for mud preparation, adjusting mud density, viscosity, acid-base property 2. Can reach the request for the mud density adjusting and preparation for the drilling solid control system of 1500-9000m 3. Getting a better mud disposal 4. Increasing jet force of the mud 5. Promoting sufficient circulation and mix for the mud.

KOSUN is one of the professional solids control equipment manufacturers, not only specialize in designing & manufacturing mud mixer, but also shale shaker, mud cleaner, centrifuge, mud agitator, etc. If interested in these products, please contact us(sales@adkosun.com).

Shale shaker for sale by KOSUN

Shale shaker are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling. They are considered to be the first phase of a solids control system on a drilling rig, they are used to remove large solids also called cuttings from the drilling fluid, more commonly called “Mud” due to its similar appearance.
Drilling fluids are integral to the drilling process and, among other functions, serve to lubricate and cool the drill bit as well as convey the drilled cuttings away from the bore hole. These fluids are a mixture of various chemicals in a water or oil based solution and can be very expensive to make. For both environmental reasons and to reduce the cost of drilling operations drilling fluid losses are minimized by stripping them away from the drilled cuttings before the cuttings are disposed of, this is done using a multitude of specialized machines and tanks.
Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.
Shale shakers are considered by most of the drilling industry to be the most important device in thesolids control system as the performance of the successive equipment directly relates to the cleanliness of the treated drilling fluid.

Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery

Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. In the typical case, the fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits.

Common uses include water, sewage, petroleum and petrochemical pumping. The reverse function of the centrifugal pump is a water turbine converting potential energy of water pressure into mechanical rotational energy.

Technical Features for centrifugal pump:

1. Can be worked as feed pump for desander and desilter, mixing pump for jet mud mixer, supercharge pump for slurry pump of drilling rig.

2. Getting a better leak tightness with tungsten carbide mechanical seal

3. With novel design for impeller, reducing load for the axial thrust, Easy installation and maintenance

Work principle for centrifugal pump

The outlet pressure is a reflection of the pressure that applies the centripetal force that curves the path of the water to move circularly inside the pump. On the other hand, the statement that the “outward force generated within the wheel is to be understood as being produced entirely by the medium of centrifugal force” is best understood in terms of centrifugal force as a fictional force in the frame of reference of the rotating impeller; the actual forces on the water are inward, or centripetal, since that is the direction of force need to make the water move in circles. This force is supplied by a pressure gradient that is set up by the rotation, where the pressure at the outside, at the wall of the volute, can be taken as a reactive centrifugal force. This was typical of nineteenth and early twentieth century writings, mixing the concepts of centrifugal force in informal descriptions of effects, such as those in the centrifugal pump.

Differing concepts and explanations of how centrifugal pumps work have long engendered controversy and criticism. For example, the American Expert Commission sent to the Vienna Exposition in 1873 issued a report that included observations that “they are misnamed centrifugal, because they do not operate by centrifugal force at all; they operate by pressure the same as a turbine water wheel; when people understand their method of operating we may expect much improvement.” John Richards, editor of the San Francisco-based journal Industry, also downplayed the significance of centrifugal force in his essay.

the three earliest solid control equipment manufacturers

As oil and gas consumption is increasing, demand of drilling equipment is also bigger because more drilling well need to be exploited. As one important component of drilling rigs, solids control equipment are also in a golden time now, which are mainly used for mud circulation to protect environment and save cost for operators.

Solids control equipments mainly include shale shaker, mud cleaner (desander& desilter), decanter centrifuge, vacuum degasser, centrifugal pump, mud tank and so on. At some areas where environment protection is very sensitive, drilling waste management equipments will be adopted.

Both the theory research and technological level of China’s drilling fluid solid control equipment have a large development. But we also must remember that there is a certain distance in the performance and life time between domestic solid control equipment and those big international brands. Especially for the material, processing technique, machining precision and quality of the common equipments, we still have lots to do to be better. What’s more, the types of many domestic solid control equipments are too few, we need to improve our research and development and add more kinds of products, so that we can supply to customers all over the world, without concerning whether our products can work for those new circumstances. Another side, we also need to perfect our solid control equipments and aim to make them suitable for all kinds of working conditions multifunction solid control system. Compact design with smaller footprint, more functional performance, convenient for transportation, even can work at different circumstances, all of these are the same aims for drilling equipment. For example, desander and desilter can be composed as one machine, which can also have the same performance as before.

Fortunately, some top solid control manufacturers in China has realized the gap between our products and that of big international brand many years ago and has been trying to shrink the gap for a long-time. As KOSUN, one of the three earliest solid control equipment manufacturers, has the ability to design and produce equipments which can be equivalent to those of big international brand. And now Kosun products perform very well in many oilfield, no matter in China or abroad.

KOSUN decanter centrifuge is an excellent tool for separating liquid

KOSUN decanter centrifuge is an excellent tool for separating liquid and solid mixtures. Industrial work and water processing plants are often tasked with purifying substances with variable amounts of solid material, and a decanter centrifuge is engineered to remove any and all contaminates from sewage and effluent sludge. Centrifuges are also capable of separating disparate fluids such as weighted or non-weighted oil and water based liquids. For example, those in the beverage industry commonly employ decanter centrifuges to extract juices. Utilizing basic gravitational force, the centrifuge divides the denser, weightier solids from the lighter, effluent liquid. Consequently, decanter centrifuges are utilized by a variety of industries with applications extending from water processing to the manufacturing of stainless steel.

Each decanter centrifuge is equipped with a hydraulic scroll drive system that allows the user to automatically control the rate of solid material discharge. The design of the device separates solids while still maintaining their weight and consistency. For example, research has shown decanter centrifuges when used to separate mud are able to sustain the material’s viscosity and original composition. The machine provides flexibility as well, with programmable frequencies and an adjustable belt that allows for altered rotation speeds. In addition, the solids control system offers long term reliability, with well maintained equipment lasting for up to 25 years.

Applications of Decanter Centrifuges

The primary application for decanter centrifuges is extracting solid materials from collected sludge. However, despite its singular purpose, the equipment can be utilized by a variety of industries. For example, oil companies employ decanter centrifuge to separate debris and dirt from crude oil. Refineries also make use of the technology in conjunction with shale shakers and mud cleaners. Companies that sell processed foods and fish depend heavily on decanter centrifuges to ensure the quality of their products. Most importantly, decanter centrifuges are critical to water processing facilities and ensuring our environment is free of unnecessary toxins.
