Recently, GN Solids Control has successfully sold its fully hydraulic centrifuge GNLW363D-FHD to Asian customers, marking a milestone that further solidifies our position in the international market. GN Solids Control, as a leading player in the industry, has won the trust of global customers with its exquisite craftsmanship and superior product quality.

The GNLW363D-FHD centrifuge, as the star product of GN Solids Control, utilizes a fully hydraulic drive system, boasting significant performance advantages.

Firstly, its hydraulic drive system can operate stably under high-temperature conditions, ensuring that the equipment maintains efficient working conditions under various complex operating scenarios. Secondly, this centrifuge features diverse solid-phase discharge capabilities, adapting to the solid-phase discharge requirements of mud under different conditions through flexible adjustments.

Hydraulic centrifuges possess several notable characteristics that enable them to excel in various industrial applications.

Firstly, during operation,

the hydraulic centrifuge generates powerful centrifugal force through the high-speed rotation of the centrifuge bowl, separating the material into solid and liquid phases within the bowl. Solid particles are compressed into the centrifuge filter bag under the action of centrifugal force, while liquid material flows out from the bottom of the centrifuge bowl through the filter bag, achieving solid-liquid separation. This efficient separation method enables the hydraulic centrifuge to excel in both processing efficiency and capacity.

Secondly, the design of the slag discharge mechanism of the hydraulic centrifuge directly affects its processing efficiency and separation effect.

Common slag discharge mechanisms include manual and automatic types. The automatic slag discharge mechanism controls the movement of the slag discharge plate through a hydraulic cylinder, achieving timed automatic slag discharge. This design reduces manual operation and improves work efficiency. Meanwhile, the spiral slag discharge plate design ensures that the material is fully discharged from the centrifuge bowl, reducing material residue and further enhancing processing efficiency.

Additionally, the hydraulic centrifuge features a compact single-skid structure, facilitating on-site installation.

The entire machine is equipped with pressure, vibration, temperature, and other detection switches, enabling real-time monitoring of the centrifuge’s operating conditions. The hydraulic differential speed transmission torque can be automatically adjusted according to actual operating conditions to adapt to various types of mud. These characteristics provide the hydraulic centrifuge with broad application prospects in the pharmaceutical, chemical, and environmental protection industries.

Taking the GNLW363D-FHD fully hydraulic centrifuge produced by GN Solids Control as an example.

it utilizes a fully hydraulic drive system, featuring high-temperature stability, diverse solid-phase discharge capabilities, and other advantages. This centrifuge employs high-precision CNC machining equipment and high-speed dynamic balance testing equipment to ensure the reliable performance of the rotor. Meanwhile, the PLC intelligent control system incorporates intelligent control and safety protection programs, making operation simpler and safer.

In conclusion, hydraulic centrifuges possess significant advantages in the field of solid-liquid separation due to their efficient separation methods, flexible slag discharge mechanism design, compact structure, and intelligent control system.

In today’s fast-paced oil and gas industry, the demand for efficient and reliable separation equipment is paramount. GN Solids Control, a leading manufacturer of decanter centrifuges, has risen to the challenge by introducing the GNLW363D-FHD, a fully hydraulic drive decanter centrifuge tailored specifically for Asia’s rigorous conditions.

Powered by a hydraulic bowl and scroll drive system, the  offers unparalleled flexibility and adaptability. This system utilizes two hydraulic oil circuits to drive both the conveyor and bowl of the centrifuge, eliminating the need for complex mechanical transmissions. The result is a centrifuge that is not only highly efficient but also exceptionally easy to operate and maintain.

A collaboration between GN Solids Control and our Swiss supplier, a pioneer in centrifuge hydraulic driving systems, has ensured that the GNLW363D-FHD meets the highest international standards. This partnership has allowed us to develop a centrifuge that is specifically designed to handle heavy mud in high-temperature environments.

The full hydraulic drive system consists of three key components: the hydraulic pump unit, the bowl drive hydraulic motor, and the scroll drive. The hydraulic pump unit feeds hydraulic oil to both the scroll and bowl drives via two separate and independently operating circuits. This ensures that the bowl’s rotational speed and the scroll’s differential speed can be adjusted independently, continuously, and infinitely variable during operation.

The pump unit is driven by an electric motor and contains all the necessary setting devices, safety valves, and pressure gauges. This comprehensive design allows for precise control over the centrifuge’s performance, ensuring optimal separation efficiency under varying conditions.

The compact skid design of the GNLW363D-FHD makes it easy to transport and install on any rig site. This, coupled with its exceptional performance, makes it a highly sought-after solution for oil and gas exploration projects in Asia.

In conclusion, the GNLW363D-FHD fully hydraulic drive decanter centrifuge is a cutting-edge solution that offers unmatched flexibility, reliability, and performance. It is the perfect choice for Asia’s demanding oil and gas industry.
