LW-NC High-speed Decanter Centrifuge

LW-NC High-speed Decanter Centrifuge is mainly composed of rotary body combination (screw and bowl, etc.), planetary gear differential, double motor (main and auxiliary motor) double frequency converter, integrated ship frame, fully closed chassis, feed pipe and automatic control system. It can be used for solid-liquid separation, particle size classification, solid-phase dehydration and liquid-phase clarification of a variety of suspensions requiring higher “g” number. 


Decanter Centrifuge


Product features: 

(1) The centrifuge adopts an integrated structure, with low rotation weight and center of gravity. The centrifuge has compact structure, small floor area, better load impact resistance, stable operation and small vibration.

(2) The centrifuge has high working speed, large separation factor, stable operation and high reliability.

(3) It is controlled by PLC+ touch screen and has a man-machine operation interface. All operations of the centrifuge can be realized through the touch screen. A number of data real-time monitoring and fault, overload alarm and automatic shutdown protection devices are set for the centrifuge to truly realize intelligent monitoring operation.

(4) It has a high degree of automation. It can realize the functions of one key start and shutdown, and can operate automatically for 24 hours, thus reducing the labor cost to a greater extent.

(5) The centrifuge base has good structural rigidity and heavy weight. Centrifuge operation is more stable, safe and reliable.

(6) The main bearing of the centrifuge is lubricated by forced oil, and the oil pump is operated and standby, which can better ensure the lubrication effect of the bearing, ensure the effective lubrication of the bearing, and make the equipment safer and more reliable.

(7) Centrifuge bowl and journal are centrifugally cast with high-strength dual-phase steel. The bowl has high strength, no welding stress and small part deformation, which can effectively avoid the deformation of key parts caused by the release of welding stress and affect the reliable operation of the machine.

(8) The centrifuge adopts energy feedback unit, which is efficient and energy-saving. The motor is driven by the common DC bus of double frequency converters, which can effectively feed back the energy generated by the auxiliary motor to the main frequency converter through the auxiliary frequency converter.

(9) The parts in contact with materials are made of high-quality stainless steel with full acid-base resistance; It can be equipped with various anti-wear technologies, such as tungsten carbide spraying, wear-resistant alloy surfacing, cemented carbide block, wear-resistant alloy sleeve and other advanced technologies, which can greatly improve the stability and reliability of the machine.
