Decanter Centrifuge Plays an Important Role in Drilling Oil Fields

Jan 26, 2024

KOSUN DC 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 environCmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solid 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.

KOSUN 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, KOSUN 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.
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.
