GN USA company’s solids control equipment

USA Solids Control system of GN america company  is for on-site treatment and removal of waste water-based mud slurry ultrafine solid development of skid-mounted physico-chemical treatment systems. 10 µg of mechanical separation of slurry separation of solid particles is very difficult, especially for about 2 μg of colloidal particles (low specific gravity solid-phase) can do about it. Whether on land or at sea, in waste management operations, treatment of waste mud face two issues: one is to reduce the volume of waste and subsequent processing costs, the other a recovery based liquid to achieve recycling. USA Solids Control system is necessary. Chemical treatment methods can make solid-free (clarification) water recovery from failure of drilling fluids, isolate and low rate of liquid-solid phase for further processing, these solid-state weight and volume than the original expiration of the mud becomes negligible, transfer and further processing costs are also much lower. In environmentally sensitive and water-poor regions in drilling operations, use of slurry dewatering system will bring about many benefits, and regulatory and economic considerations are almost essential.


The solids Control system for colloids or close to the colloidal particles, and factors that contributed to the solid phase precipitation is far from overcoming fluid relative to its suspension. Chemical treatment methods can change characteristics of mud, so that most of the suspended particles can be separated  by mechanical methods. Centrifuge feed stream of appropriate chemical (flocculation and other reagents) enables colloidal particles aggregation formation of floccules, resulting in slow precipitation under the action of gravity or centrifugal force. This principle has been widely applied in sewage treatment and other practice, but the nature of the solid-liquid system of mud and sewage are very different and, therefore, chemical reagents selection and isolation of structures are very different.

Drilling fluid solids control system is an important part of modern drilling. Drilling fluid solids control system is to ensure that the normal circulation of drilling mud in the process of drilling and stable performance of the important equipment, drilling fluid solids control The solid control system The solid control system System is mainly composed of mud tank, vibrating screen, vacuum degasser, desanding cleaner, silt cleaner, mixer, centrifuger, the funnel of mud gun, mixed, the sand pump, mud agitator, increase the pump, shear pumps, etc. All levels of solids control equipment. Production, workover, drilling mud solid control system. Especially the workover rig with solid control system, developed by crown to solid control, substantial and durable, unique anti-corrosion technology, very suitable for workover treatment of actual production.

operate the cuttings dryer system after long time off status

If we operate the cuttings dryer system after long time off status, we need to inspect motor rotary unit on insulation. Use 500V Ω gauge, get resistance is not larger than 0.5MSZ, we can run the shaker

Notice: ① If the motor doesn’t run at all, we must shut off the power immediately to avoid motor broken
② After starting motor, to inspect, whether this is any problem. If there is any break off or uncommon noise. If two motors are not running in-phase we need to stop the motors and get rid of problems then turn it on again for operation
③ When motor is under cold status, should not be started 5 times continuously; when motor is turned off under hot status, the restart can not be over 3 times continuously
Shaker screen maintenance
① Before every shut off, the shaker should run without any medium for 5-10 minutes, at the same time, use clean water to flush screen clean
② Every time finish operation, the shaker frame and screen should be flushed by water (summer) or steam (winter), there should be not much sediment on shaker frame and shaker screen. Especially when the drilling mud has large viscosity and high density or screen is finer than 60 mesh. Otherwise, the particles and fine sand on screen will block screen hole, when we start shale shaker, it will decrease filtration result and lead drilling mud flow away, lose much unnecessary cost.
cuttings dryer maintenance
Electric control cabinet is explosion proof magnetic starter, the electric principle is as fig VI, if there is any trouble we must shut off the power, and repaired by electrician or specific person
