Many people can easily know how to choose a decanter centrifuge, but it is a little difficult for them to select a suitable model of centrifuge. Here is a simple method to judge a proper model for you.
Decanting Centrifuge
First, the model of a decanter centrifuge represents the following meanings: For example, LW450*842, a model of decanter centrifuge, among which L means Luoxuan in Chinese Pinyin, W means Woshi in Chinese Pinyin, 450 means the bowl diameter of decanter centrifuge, and 842 means the bowl length of decanter centrifuge.
A suitable model ofdecanter centrifuge can not only solve production problems and improve work efficiency, but also save production cost and reduce business risks. Several main factors that determine the centrifuge model are as follows:
decanter centrifuges
Speed of decanter centrifuge: The speed of a common decanter centrifuge is more than 2000RPM. For some materials hard to separate, a higher speed is required. The higher the speed is, the higher the separation factor of centrifuge, the better the separation effect.
Material of decanter centrifuge: PH value of materials to be treated determines the bowl material of decanter centrifuge. Different materials have diverse physical and chemical indexes in their abrasion and corrosion resistances. Overseas decanter centrifuges are generally made of 316L or duplex stainless steel, with wear parts made of ceramic materials.
Differential control of decanter centrifuge: Different differentials have different control accuracies, service lives and maintenance costs. The higher its differential accuracy is, the better its adaptation to materials is. So it is advisable to select equipment with a high differential accuracy.
Length-diameter ratio: The bigger the length-diameter ratio of decanter centrifuge is, the higher the handling capacity is, the lower the moisture content is.
Control system: At present, almost all of equipment manufacturers at home and abroad have achieved a full automatic control over the equipment.
Installed power: As for a control over energy consumption, generally speaking, domestic equipment has a higher energy consumption ratio, while foreign equipment has a lower one.
Manufacturing technique: Since a decanter centrifuge is a kind of separation equipment with high precision machining requirements, the centrifuges manufactured by enterprises without a precision machining capability will suffer from a high maintenance ratio and a restricted handling capacity.
Decanting Centrifuge Separation Principle:Taking advantage of the principle that the light liquid, heavy liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid particles in the liquid to deposit can be achieved.
Decanting Centrifuge
KOSUN DC series decanting centrifuge is used in separating suspension of solids phase with particle diameter(d≥2μm) for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The centrifuge must test the dynamic balance for smooth operation over long periods.Speed ranging from 0 to 3900 RPM, generating centrifugal forces reach up to 3000G.
DC decanting centrifuge is 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 mud 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
In China solids control industry, KOSUN is a solids control leader and expert in drilling waste management. KOSUN is capable of providing customers with such four series as oil & gas drilling solids control equipment, centrifuge, drilling waste treatment equipment and drilling security equipment, including 25 categories of products,such as 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, complete solids control system,etc.
In the wholesolids control system, the drilling mud Decanter Centrifuge is the most important solids control equipment, it is the forth stage equipment and it decides the quality of drilling fluids in a way. The first equipment is oilfield shale shaker, it is one of the most important equipment, too. The second stage equipment is desander, third equipment is desilter. Sometimes they are combined to be as one equipment—drilling mud cleaner.
Oilfield Solids Control
KOSUN Drilling Fluid Centrifuge is designed to speed up the settling process. The rotating speed is transformed into centrifugal force inside the rotating assembly to accelerate particle settling in accordance with Stoke’s Law. In essence, a centrifuge is a miniature settling pit that alloys very rapid settling of solids under controlled conditions. Though much more complicated than a hydrocyclone, centrifuges have the advantage of achieving extremely fine cut points. Centrifuges can improve the cut point by a factor of 6X when compared to a prototypical shaker/hydrocyclone system and can dramatically increase the drilling fluid life.
KOSUN Decanter Centrifuge can effectively remove the harmful solid particles from the oil and gas drilling fluid, improve the mud performance, ensure the drilling safety, lessen the pollution of oil/gas reservoir and reduce the mechanical abrasion of drilling equipment. 1500-3000 rpm centrifuge can separate 2-7μm solid particles. It is an ideal choice for drilling mud purification.
Drilling fluids is important for the whole drilling system, but is too expensive, we usually spend abundant expense for that. But if we clean the drilling fluids and use it for recycling, we can save more drilling cost. At this time, the drilling fluids solids control of the drilling fluids seems to be so important.
In the whole markets, centrifuge or even decanter centrifuge has been used in most fields. There are also mutual types or styles of decanter centrifuge in different fields. We just take oil drilling industry as an example,there are RFD decanter centrifuge, VFD decanter centrifuge, Disc centrifuge, hydraulic centrifuge, etc.
Decanter Centrifuge
Now KOSUN want to share some necessary tips about safety operation regulation for decanter centrifuge. The following content is about the topic of “6 Tips of Safety Operation Regulation for Decanter Centrifuge”.
Decanter Centrifuge
Just as we all know that Decanter Centrifuge is one kind of machine revolving at high speed. During operation, revolving drum will generate strong centrifugal force (it is not like the solid control system, to some extent, decanter centrifuge is a core part for a whole solid control system and water based mud unit). To ensure the safety of operators and equipment, the following safety rules shall be strictly followed when using it.
Pay more attention for original Instruction Orders or Steps. Through dynamic balance of revolving drum parts of centrifuge, during assembly, original installation order shall not be changed and there shall be no parts omitted. Threaded connection part shall be installed in place; during assembly, if there is assembly mark, the mark shall be aligned. Before startup, operating pump system shall be inspected and there shall be no water leakage under close state of magnetic valve.
Keep the decanter centrifuge off. Before clamping revolving drum clamp ring and fixing inlet/outlet device and other fastening screws, decanter centrifuge shall not be started.
Before completely stopping revolving drum, any part of equipment shall not be loosened.
During operation, if abnormal vibration of decanter centrifuge is found, power shall be cut off for emergency shutdown. After revolving drum is completely stopped, each part shall be disassembled cleaned and inspected and attention shall be paid to assembly order and position. After the causes of abnormal vibration are found out and removed, reassembly and startup can be carried out. Time interval between re-startup and shutdown shall be more than 4h (This item is also suitable for mud cleaner).
Flame heating or repair welding of main revolving drum parts is not allowed, especially revolving drum body, revolving drum cover and clamp ring.
Use of revolving drum parts and revolving drum parts of other equipment shall not be mixed, even the revolving drum parts with same model.
3 Phase Decanter Centrifuge
The above 6 tips or we can call it as steps should be kept in our mind, they can help us improve our working efficiency. Just as I mentioned in the post, you could find more information about solids control system, drilling waste management unit, oil recovery unit, and some other solids control equipment, such as mud cleaner, sand pump, vacuum degasser, cutting dryer, etc. In another words, KOSUN could be your better cooperator.
A decanter centrifuge is a very useful equipment for any drilling site.A decanter centrifuge is basically used to dilute the fluid that is extracted from the gas or oil mine. Generally, the liquid that is extracted from a mine is of highly concentrated and coagulated. So, extracting minerals from them is practically impossible. In order to thin up the extracted fluids, a decanter centrifuge is used. By using the rotational speed of a decanter centrifuge, the highly concentrated are turned into minerals extractable thin liquid.
There are three basic designs of decanter centrifuges. The first one is vertically oriented decanter centrifuge, the second one is horizontally oriented decanter centrifuge and finally the third one is conveyor or scroll decanter centrifuge. In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically.
Vertical decanter centrifuge is very effective for high temperature and high pressure work. A horizontally oriented decanter centrifuge gathers the fluids or solids generated from high rotation in horizontal orientation. A horizontally oriented decanter is very effective for high pressure works as it provides a strong organization due to its horizontal orientation. Lastly, a conveyor or scroll centrifuge is basically a rotating machine inside a bowl.
The first thing that should be done to maintain a decanter centrifuge is to replace any hydraulic suction filter and replace hydraulic returns filter. It is a very important step for the oil and gas drillers. As when the oil or gas drilling goes on both the hydraulic suction filter and the hydraulic returns filter undergo an extensive pressure. So, there is a huge possibility of both of them to be worn out. So in that sense, both of the filters must be checked regularly and be replaced when it is necessary.
Another important thing that is required to do in order to maintain a decanter centrifuge is greasing the machine. It is very important. As decanter centrifuge is basically used in a heavy working areas, the machine can easily be stuck or jammed off. In order to avoid that, greasing is very important. Oil lubricated gear box greasing and recirculating oil greasing are two very effective methods for greasing. A very significant task for managing a decanter centrifuge is adjusting speed sensor to it. It is very important just because adjusting a speed sensor enables drillers to control the differential speed.
Beside these above mentioned activities replacing hydraulic motor sensor, bowl belt replacement, scroll belt replacement and regulating the weir plate are some of the steps that should be taken to maintain a decanter centrifuge.
