A .The adjustment of the drum speed.


The adjustment of the bowl speed is performed in  manual adjustment or decanter centrifuge plate prescribed maximum working speed following the adjustment.

Different rated speed by installed different size wheel by diameter for driving the main belt wheel to set different drum operation speed

In variable frequency drive decanter centrifuge will paired with control panel that allow increase and decrease the drum speed.

By fine-tuning the speed of the drum, it can perform more precise solids particles separation.  It can also improve the wear of the drum, the vibration and the noise to extend the service life of the decanter centrifuge.

The separation purpose or drilling fluid solids content  is by the choice drum speed. For instance, barite recovery or processing high-density mud, it is suggested that the low spending  speed. For general medium density mud prefer choose medium or high speed.  The low density mud is ideal for using high speed decanting centrifuge.

B. The adjustment of the differential drive


Centrifuge differential speed (back drive is also refer by) in its within the prescribed scope of, do not suggest user to adjust and it can only adjust in a small range change the parameters.

Different speed centrifuge adjustment methods are remove the original auxiliary motor pulley, and reloading large diameter or smaller diameter belt wheel  Auxiliary motor pulley  change the differential input shaft speed enhancement in result of differential speed decreased. On the other hand, it can also cause differential speed increase.


Operators must understand that regular maintenance on the centrifuge such as regular cleaning the inlet and outlet by filling water or diesel depends what kind of fluid it needs process.  It is also crucial that  add grease to the bearing parts to ensure proper lubrication.

Vertical type, horizontal type and spherical type structure are available shapes for making liquid gas separator from various manufacturers. Most manufactures are produce vertical type and horizontal type liquid gas separator.  Two more structure type available under the horizontal type, which is single tube and double tube.  Each type of separator has specific advantages and limitations. The factors choosing separator type is based on several factors including characteristics of production system to be treated, floor space availability at the facility site, transportation and cost.


Vertical liquid gas separator

The inlet diverter baffle is a centrifugal inlet device making the incoming stream spin around. This action forces the liquid droplets to stay together and fall to the bottom of the separator along the separator wall due to gravity.

The vertical type liquid gas separator is use to treat low to inter mediate gas-oil ration well stream with relatively large slugs of liquid. The handle slugs is greater of liquid without carryover to the gas outlet and the liquid level control is not as critical.

Mud Gas Separator

Mud Gas Separator



Horizontal liquid gas separators

In horizontal separator, gas flows horizontally while liquid droplets fall toward the liquid surface. The moisture gas flows in the baffle surface and forms a liquid film that is drained away to the liquid section of the separator. The baffles need to be longer than the distance of liquid trajectory travel. The liquid-level control placement is more critical in a horizontal separator than in a vertical separator because of limited surge space. Typically, horizontal type liquid gas separator is ideal choice because of the low cost to make and widely used for high gas-oil stream, foaming well streams,  and liquid-from-liquid separation. They have much greater gas-liquid interface because of a large and long baffled gas separation section. Horizontal liquid gas separator is easy to skid-mount and service and require less pipe- connection for field and minimize space requirements. GN Solids Control sell a series of solids control equipment and drilling waste management including mud cleaner, shale shaker ,screw conveyor, desander, desilter ,vacuum degasser ,mud agitator,mud tank ,etc. GN keeps research and develop the best technology to manufacture top quality  for our clients, welcome to cotract us to know more info from our sales team.

The GNZCQ270 Vacuum Degasser is a rugged vacuum unit that is designed to safely and effciently remove 98% of entrained air and gases such as H2Sand methane from drilling mud.Unlike the traditional vacuum degasser,GNZCQ vacuum degasser is a self-contained unit.The gas-cut mud is drawn into the degasser by a vacuum created by a regenerative vacuum without needing centrifugal pump.

Working Principle of GNZCQ270 Vacuum Degasser

ZCQ series Degasser belongs to the vacuum degasser, namely use the suction effect of the vacuum pump to create negative pressure region in the vacuum tank, and the mud enter the hollow shaft of the rotor through the suction tube under the action of the atmospheric pressure. And then the mud spray to the tank wall through surrounded windows of the hollow shaft. As collision and the function of separate wheel, the mud separated into thin layers, bubble immersed in the slurry breakup and gas escape. Gas is discharged to safe zone from gas separator through the suction of vacuum pump and separation of gas-water separator. the mud is discharged outside of the tank by impeller. As the main motor start first, the impeller associated with the motor is in a high-speed rotation state, so mud gets into the tank only from the suction pipe not be sucked from the liquid discharge tube.

From 2011,GN start building atmospheric degasser.This type degasser is more reliable,with simple design.

Features & Benefits of Atmospheric Degasser

The GN Atmospheric/Centrifugal Degasser is a special in-tank alternative to the standard GNCQ series Vacuum Type Degasser. The GNAD Series Degasser is a self contained unit without needing for centrifugal pump to feed drilling mud.

The GNAD Series Atmospheric/Centrifugal Degasser retained gas from drilling muds. Atmospheric degassers process mud by accelerating fluid through a submersible pump impeller and impinging the fluid on stationary baffles to maximize surface area and thus enable gasses to escape to the atmosphere.

Features and Benefits of Vacuum Degasser

GNCQ Series Vacuum Degassers that are able to service the needs of any application .It is usually fixed after the shakers. Each degasser effectively and efficiently removes gases from gas-cut mud, thus ensuring that the proper mud weight is pumped down hole. In doing so, the degassers are able to aid in the prevention of potential blowouts. Unlike the traditional vacuum degasser, GNCQ vacuum degasser is a self-contained unit. The gas-cut mud is drawn into the degasser by a vacuum created by a regenerative vacuum without needing centrifugal pump .Moreover, GN degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter. GN also have Atmospheric/Centrifugal Degasser available as an alternative to the standard vacuum type degasser.

Vacuum degasser breif info

Vacuum degasser is a special-purpose device for the treatment of gas-cut driling fluid . It is a new type one we have designed and developed by combining different sorts of degassers from home and abroad . It’s applied to match to various mud purification system Vacuum degasser is very important for returning mud gravity , stabilizing mud viscosity and reducing drilling cost . Also , at the same time it can be used as a heavy-power agitator during the operation of gas free mud .

Working principle of vacuum degasser

This degasser belongs to a kind of vacuum . One which uses the suction of the vacuum pump to establish an under balannced pressure area in the vacuum cylinder and causes the drilling fluid into the hollow shaft of the rotator through suction pipe under the atmosphere pressure, and then lets the fluid spray to the walls of the cylinder from the windows on the hollow shaft , now the gas bubble cut in the mud may break and run off in the funtion of vacuum pump suction to a saft area due to the fluid collision and bubble separator.
