Derrick DE-1000FHD Full Hydraulic Drive Decanter Centrifuge VS ZHFHD-1400
Decanter centrifuge is a commonly used solid-liquid separation equipment, which is widely used in various fields. Such as: oil drilling, subway shield, paper mill, sewage treatment, river dredging, horizontal directional crossing, building piling and other fields. The separation of the Decanter centrifuges mainly uses the strong centrifugal force generated by the high-speed rotation of the centrifuge drum to accelerate the sedimentation speed of the particles in the liquid, and separate the substances with different sedimentation coefficients and buoyancy densities in the liquid.
Decanter centrifuges can be divided into high-speed centrifuges and medium-speed centrifuges according to the rotational speed. High-speed Decanter centrifuges can separate solid particles of 2-5 microns, and medium-speed decanters can separate solid particles of 5-7 microns.
Decanter centrifuges can be divided into two-phase (solid phase and liquid phase) separation Decanter centrifugesand three-phase (water, oil and a small amount of solid phase) separation Decanter centrifuges according to the separated substances.
Decanter centrifuges can be divided into electric drive Decanter centrifuges and Hydraulic Drive Decanter centrifuges according to the driving mode. Electric drive Decanter centrifuges motor drive, more common. Since the Fully Hydraulic driven Decanter Centrifuge. centrifuge can be used for aggravating the separation of mud in a high temperature environment, it can achieve better results. ZH, as a professional centrifuge manufacturer, has developed its own Fully Hydraulic driven Decanter Centrifuge. The fully hydraulically driven Decanter centrifuges drives the bowl and vortex with two independent oil circuits, making their speed independently variable.
