high speed centrifuge

In this article,
we will continue to introduce the key features with GN’s decanter centrifuge.

  •  Easily adjustable fluid outlet on the drum;

in order to change the drying degree of solids or clarity of liquid, the size
of fluid outlet on the drum needs to be changed by customer.

GN’s centrifuge, there are 6 fluid outlets at the big end of the drum and there
is a cover plate mounted on each outlet by bolts. It just needs to loosen the
bolts and angle the cover plate and the outlet size could be changed easily.

  •  Feeding fluid from the big end of centrifuge; 

all GN’s centrifuges, the drilling fluid goes into the centrifuge from its big
end. Compared with feeding fluid from the small end of centrifuge, on some
extent it will improve the working efficiency by feeding fluid from the big end
of centrifuge.

  • Parts from world-famous suppliers;

bearing is 1 of the most important parts for the centrifuge. With GN’s
centrifuge, all the bearings are world-famous brands like SKF (Switzerland
brand), NSK (Japan Brand), FAG (Germany Brand).

All the electrical components used in the electric cabinet are also from famous
brands like SCHNEIDER (France Brand), SIEMENS (Germany Brand), CHINT (China
Brand), ABB(Switzerland Brand).

example, for the inverter of GN’s variable speed centrifuge, it is from ABB

adopting these high-quality parts, GN guarantees to provide the best centrifuge
with perfect work performance and longer life to all the customers from the

  • Explosion-proof property;

Exd Standard;

Positive Pressure Type;

the motors and electric cabinet with GN’s centrifuge get through the IEC and
ATEX certification and could meet the explosion-proof requirement in developed

  • PLC intelligent control 

the electric cabinet of GN’s variable speed centrifuge, it has a graphic user
interface and is PLC intelligent control, which could achieve centrifuge’s
self-protection and guarantee its most effective work.

In this article, we will mainly introduce the key features about the
centrifuge manufactured by GN. 

1. From minimum 40GPM to maximum 484 GPM, GN’s Centrifuge could meet
the treatment capacity requirements in different industries. Like oil & gas
drilling industry, HDD & CBM industry, water well & geothermal well
drilling, industrial waste water treatment, etc. 

2. Besides, fixed speed & variable speed, standard configuration
& high configuration are also available and provide different options for
the customer.

  • High-class raw
    material and manufacturing process

1. Drum                               

1).As 1 of the core parts of centrifuge, some company adopts the
manufacturing process of sand casting or solid-solution treatment. But the drum
of GN’s centrifuge is made from S304 or duplex 2205 stainless steel by
centrifugal casting, which could guarantee the drum rotates steadily at a
higher speed and gets a longer life. 

2).The solids
discharge ports on the drum and the fluid ports on the helical pusher are
protected by special ceramic insert.

2. Helical Pusher

1).The helical
pusher of GN’s centrifuge is S304 or S316 stainless steel. By special
solid-solution treatment over 1000℃, the helical
pusher get a higher strength and longer life. 

2).Besides, as the
helical pusher is used for pushing the solids continuously when working, the
wear of the pusher will be serious if no protection. There are special Tungsten Carbide tiles or Ceramic Tiles fixed around the
edge of pusher for protection. The tiles have long life and are easily for replacement. 

  • Compact Structure

1). Usually, there are
2 motors (primary motor and secondary motor) equipped with each centrifuge. Compared with the
centrifuge made by some company, GN’s centrifuge has a much more compact structure,
as the 2 motors are installed at the same end of centrifuge, which also gets a
bigger space and facility the maintenance.

the secondary motor connects directly with the gear differential so that the
belts are also left out.
