KOSUN LW Series Decanter Centrifuge

XI'AN, China - July 13, 2013 - PRLog -- What is a good Decanter Centrifuge? How to choose a good one? Which brand is a reliable one? It is said that KOSUN LW Series Decanter Centrifuge is a good choice.

What is Kosun LW Series Decanter Centrifuge Application？

KOSUN LW 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.

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.

What is LW Centrifuge Working Principle

Separation of solids and fluid is done in the drum. Its principle is: high-speed rotating drum drive inner mud rotate speedily and then the mud is thrown onto drum’s surface to form a fluid circle. Under the centrifugal force, solid sedimentary force in the separated liquid will be several hundred even thousands of times heavier than its own gravity so as to separate the solids from the suspension quickly. The ratio of centrifugal force which the solids have gained and the solid’s gravity is called as separating factor. The larger the centrifugal force, the finer the separated solids, so three types of centrifuge can get according to separating factor.

LW Hydraulic Coupler Working Principle

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.

What is GLW Gear Box Working Principle

Differential gear in fact is a secondary planet slowdown gear, there is ring gear in the shell internal processing. the shell is rotated with the roller, the left belt pulley drives the first sun gear on the input gear rotate, the first sun gear engaged with the ring gear of the shell through the first planet gear, by doing this, the shell rotating speed and the input bearing rotating speed combined into a first tumbler’s rotating speed，and the secondary sun gear output the combined speed to the second part, the transmission principle of the second part is the same with the first one, and finally drives the screw propeller rotate through the output bearing.
