GREEN GR Series Decanter Centrifuge is used in separating suspension of solids phase with particle ≥2μm in diameter for drilling mud and fluids handling.
Decanter Centrifuge Features and Benefits:
1. Innovative design includes longer bowl, allowing drilling fluids to thread through more slowly, thus resulting in drier solids and finer separation point;
2. Big bowl offers big volume. It also generates high-G force;
3. Stainless steel bowl, scroll, compartment are available and covered with corrosion-proof coating so as to have longer lifespan;
4. Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maximum solids control efficiency.
5. German FAG or Swedish SKF brand bearings are available;
6. Electrical Components complies with SIEMENS/Schneider ATEX or IEC Ex.
7. Screw pump and submersible slurry pump are provided to meet liquid feeding requirements of centrifuge of various customers
Oilfield Decanter Centrifuge Working Principle:
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 the spiral propeller rotate in the same direction with a certain differential speed.
Decanter Centrifuge Application:
GREEN GR Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G.
GREEN Decanter Centrifuge can meet with different requirements of mud treatment under various drilling conditions, that can do sedimentation and separation for particles more than 2 μm. After treatment, the mud can achieve ideal viscosity and proportion, resulting in better recycling, high efficiency, saving and environment protection.
The series of centrifuge by our company has been developed many years with the continuous improvement and optimization design, which possesses the characteristics of good result of separation and settlement, as well as large quantity, reliable work, longer life, lower energy consumption, easy maintenance, smooth operation, lower noises, etc.
To ensure that the effective treatment result and long service life, the important parts adopts high quality stainless steel, forging material, strengthen heat treatment and strict control processing. And on each part that easily wears take spraying wear-resisting layer and mosaic of hard alloy, etc. The overflow of the main drum mouth using adjustable poling board, it can be adjusted anytime according to different sludge treatment.
To meet the requirements of the development of modern drilling engineering, GREEN developed and equipped with the explosion-proof variable frequency control system which could adjust separation factor and drum rotational speed. By this new technology, make the centrifuge adapt property changing of mud during the operation process, that makes the treatment more effective and perfect.
A VFD ( Variable Frequency Drive ) module monitors and controls both the main and back electric drives. The operator can manage bowl and scroll speeds via a touchscreen that also displays input from the various sensors, including temperature, current, rotational speed and vibration.
A professional supplier which specialized in solid-liquid separation equipment in the energy industry, mainly supply drilling shale shaker, decanter centrifuge, mud cleaner, desander and desilter, mud agitator, vacuum degasser, shaker screen, cyclones, slurry pump and solid control equipments spare parts products etc.
