KOSUN DC series horizontal decanter centrifuge is used in separating suspension of solid phase with 2～70% solid concentration, liquid viscosity ≤0.01PaS, particle diameter d≥2μm, in clarifying suspensions with little solids as well as amorphous material that brings difficulties for filtering cloth regeneration and suspensions which have a big change range in solid phase concentration.

 Decanter Centrifuge

The centrifuge is also used in the separating of solid and liquid in the fields of petroleum, chemical industry, food, pharmacy and environmental protection, carrying out dehydration of solid phase, liquid clarifying, liquid-liquid-solid separating, granularity grading and other separating processes.

How does hydraulic coupler of decanter centrifuge work?

Hydraulic coupler mounted on main motor, it is a hydrodynamic transmission device, have the function of buffering starting shock, reduce starting current and overload protection . It consists of shell, turbine, pump wheel, input shaft, output pulley; shell is joined with turbine, output pulley connect with shell; input shaft connect with pump wheel, working oil is filled into the shell, pressure emerges in service oil caused by centrifugal force when motor axle drive turbine to rotate, in this way, power is transmitted. Motor’s no-load starting can achieve when motor start-up in lower speed because less liquid pressure and smaller drag exist at this time when reaching its rated rotational speed, oil pressure increase and drive load to rotate, this is coupler’s buffering starting shock principle; When load is too heavy, speed differential between pump wheel and turbine increase , oil heated immediately, melt able plug in the coupler will be melted when oil temperature exceed 120°c, oil sprays out to make input separate from output, thus main motor is protected and make sure no burn occurs, oil is the media of transmission, so its performance will influence coupler’s working condition. Replace the oil as required.

Feature of KOSUN DC Series Decanter Centrifuge:

KOSUN DC series horizontal centrifuge is a professional solid-liquid separation equipment(also called drilling fluid solids control equipment) designed according to the petroleum drilling fluid features. And the equipment can perform feeding, centrifugal settlement and unloading as well as other operation procedures, used in recovery barite, removing fine solids, lowering solid content in the drilling fluid, controlling the drilling liquid viscosity and density to guarantee the liquid performance and has a significant effect on fast drilling.

1. easy adjustment for liquid pit;

2. fluent slag transporting and draining;

3. convenient washing and maintenance.

In China solids control, KOSUN can supply various specifications of decanter centrifuge, like high-speed decanter centrifuge, low-speed decanter centrifuge.
