Product Description

Separation principle: Under the action of centrifugal force field, when the density of the solid phase is greater than that of the liquid phase, the solid phase is deposited on the inner wall of the bowl, and the screw conveyor and the bowl move the solid phase to the discharge under the set differential speed. When it enters the cone end of the bowl and reaches the discharge port, it leaves the overflow surface, the moisture content of the solid phase is further reduced, and is discharged to the discharge port. The liquid phase overflows from the overflow port at the big end of the bowl.
The overflow radius can be adjusted to suit different materials. The smaller the overflow radius, the higher the moisture content of the solid phase and the lower the solid content of the liquid phase (the liquid phase is clearer); the larger the overflow radius, the lower the moisture content of the solid phase and the lower the solid content of the liquid phase. High (more turbid liquid phase).
LWX horizontal decanter (centripetal pump liquid) centrifuge: the liquid discharge method is centripetal pump, and the liquid discharge radius is adjustable. The outlet liquid has a certain pressure and can be directly connected to the outlet pipeline.
LWXF horizontal decanter (explosion-proof) centrifuge: Before starting the centrifuge, the centrifuge inner cavity and the casing cavity are replaced with nitrogen, and the oxygen content concentration in the inner cavity is below the set safe concentration before it can be started. Nitrogen is added during operation. Nitrogen seals are installed at both ends of the centrifuge to ensure the isolation of the centrifuge cavity from the outside and meet explosion-proof requirements. The motor of the centrifuge and the electrical components on site must meet the explosion-proof grade of the working condition. The transmission belt is antistatic and has static grounding. In explosion-proof applications, centripetal pumps are generally used. The solid outlet of the centrifuge must be connected to the fan and other devices.
The settling velocity of the solid-liquid two-phase mixture is determined by the dispersion state of the suspended matter and the two-phase density, and is also significantly affected by the surface state of the solid-liquid two-phase, because it can affect the stability of the mixture and control the interaction between particles. state of contact. The properties of these systems may also be time dependent, as some suspensions have settling velocities that vary with time.
Settling velocity is the main basis for type selection. By analyzing and testing the physical and chemical properties of the solid-liquid mixture, determining the separation process, and conducting necessary technical and economic analysis (product quality, yield, energy consumption, production capacity, operation safety, control), select the appropriate separation equipment.
Generally, the sedimentation method is more economical than the filtration method, especially in those cases involving high-volume, continuous liquid flow, gravity settling is considered to be the first choice.
When the density difference between the solid-liquid two-phase is very small, try not to use the sedimentation method for solid-liquid two-phase separation. Or increase the density difference through appropriate process methods, or increase its separation power through the action of centrifugal force.

 

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

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.

 

Shenzhou LW 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.

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, Shenzhou 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.
