How to maintain the drilling mud decanter centrifuge ?

KOSUN decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system.oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.
How can we maintain the drilling mud decanter centrifuge to keep its high capacity and serve oilfield solids control system better? The following will give you the answers.

1. Minimize the need for gears or belts to drive the centrifuge.
2. Control and maintain speed during the decanting process.
3. Develop high torque at very low speeds.
4. Two motor applications, one for the bowl and one for the scroll.
5. The bowl has a very high-reflected inertia.
6. The scroll is usually in continuous regeneration, as it runs at a slower speed than the bowl and is pulled along.
7. Torque limiting on the scroll is very important.
8. Some configurations require zero-speed operation of the scroll ( differential gearbox ).
9. Dynamic braking or regenerative modules may be required if the bowl is NOT driven by a drive.
10. Explosion-proof environments.
KOSUN drilling mud decanter centrifuge is built around a slender cylindrical bowl with a relatively large length/diameter ratio and a conical end. This bowl rotates at speeds of up to 4000 rpm (according to model), producing centrifugal force of anywhere from 300 to 3130 G. The other key components include a main drive motor, heavy-duty gearbox, back drive motor and control panel.

Defference on vacuum degasser and poor boy degasser fluid processing

Vacuum degasser gas cut drilling fluid is used to remove the gas, its capacity should be able to reach full flow processing. Vacuum degasser must be placed after the drilling fluid shale shaker sand pump drilling fluid prior to treatment. Because drilling fluids containing gas, drilling centrifugal sand pump cavitation will occur, not only drilling sand pump cavitation performance degradation, noise and vibration, shortened life expectancy, serious cause fluid sand pump is not working or damaged.
Gases are entrained in drilling fluids from the wellbore during normal drilling operation as well as during “kick” or well control situations ,these gases may bring 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 drilling fluid degasser.

Vacuum degasser is a special-purpose solids control equipment and a new type one for the drilling fluids system. It can get rid of various gas of invasive drilling quickly. Drilling mud vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time vacuum degassing machine can be used as a heavy-power agitator and supported applicable to all types of drilling mud purification system. The drilling vacuum degassing unit design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.
Defference on vacuum degasser and poor boy degasser fluid processing
Vacuum degasser usually used to separate less gas than poor boy degasser. Although they both are degassing devices. Poor boy degasser is set up before shale shaker in the oil and gas well drilling. Before fluid flowing to shale shaker it need to be processed by poor boy degasser for safety working condition. Especially when the well depth is more than 4KM.

Such as oil well drilling, gas drilling, water well drilling, geothermal well drilling, etc. The shakers will be used in all solids control system. Then the shale shaker screens will be used in wide range as shakers. There are so many different shaker screens fit on various shale shakers. The difference is on type, shape, material, etc.Shaker screens according to different division way including quantity different types. Such as according to tensioning way, appearance, material, manufacture technique or process, applications, etc.
Including the hook strap shaker screens, pre-tensioned screen or frame shaker screen the flat type shaker screen and corrugated shaker screen, the polyurethane screen, the composite frame shaker screen, and so on。
In different period, people invented different types of shaker screens, such as conventional flat screen, corrugation screens, and with square meshes, hexagonal meshes, diamond meshes, etc. And different geological condition may require different ability and type of shaker screens. But in different times, people use different ways to describe the ability of screens.

KOSUN shaker screen characteristic is wear resistance,wearability,rating of temperature,low cost,easy disassembly,conductivity (powder) liquid,trapping(dreg) effect is good.The composite material is employed for producing the frame which is constructed with many stiffeners made of high-strength steel for interior structure supporting. This kind of structure can increase the life span of the product and the processing capacity for drilling fluid. It can divide the screen mesh into more small panels, which can help to distribute the mechanical stress evenly. Meanwhile, it won't affect the normal use of the product even when the mesh is torn up in some places.
The shale shaker is the first stage of solids control equipment in drilling purification system. It can remove cuttings above 75μm brought from the drilling well to leave the liquid with smaller particles into the tanks below, which will flow into next grade solids control equipment to be treated.
KOSUN linear motion shaker is especially effective while drilling top-hole sections where heavy and high-volume solids are usually encountered. In these intervals, shakers may generate powerful G-forces and its effective vibrating motion can quickly remove the dense solids from screens and particles from wells.
