Decanter centrifuges have been working as really essential equipment for separating ever since it came out yrs ago, it is widely used in many industrial sectors, including the food industry, substance industry, pharmacy industry in addition to oil and gas industries.
Divided from the types, the decanter centrifuges could be defined as horizontal decanter centrifuge and vertical decanter centrifuges. The working principles work the same way that by using the different centrifugal forces laid on the distinct size materials, a certain sort of particles are separated out there. In oil and gas industry, side to side decanter centrifuges are commonly utilized while they use Vertical Cuttings Dryers in front of the horizontal decanter centrifuges. GNLW series decanter centrifuges covers all needed sizes and applications useful for oil and gas drilling, such programs including following:
1 . GNLW452, 18 inch diameter involving bowl, big bowl centrifuge, middle speed. suitable for solids control application in gas and oil drilling, especially for barite recuperation. Barite is heavy and also expensive drilling material from the drilling liquid and could be fitted for re-use if it is very well recovered. This model of GNLW Centrifuge is normally fixed velocity as standard configuration, however it still has 3 optional rates by changing the pulleys and belts

2015.12.11 GN centrifuge
2 . GNLW363, 14 inch diameter connected with bowl, most popular size throughout oil and gas drilling, high speed as much as 3900RPM, it provides the most programs among all GNLW centrifuge versions, in case of fixed speed GNLW363, GN designed 3 various speeds based on the experiences inside previous projects, and user could choose via employing different pulley and devices. In case of VFD controlled, GN also have 2 optional VFD control panel for selection, the speed could be set coming from 0 rpm to 3200 rpm.
3. GNLW453-VFD decanter centrifuge, 18 inch jar diameter big bowl centrifuge, with larger length size ratio as above mentioned GNLW452, higher speed and for extra excellent particles comparing with GNLW452, but with larger treating ability than GNLW363.
4. Major big bowl centrifuge GNLW553C-VFD with 22 inch pan diameter, which is no doubt a major guy in centrifuge family members, and GNLW223 decanter centrifuge with only 9 half inch bowl and a very high velocity, which is a baby member throughout GNLW centrifuge family.

The mud guns that place in the mud system’s function is to move drilling mud from tank space to another.  GN Solids America LLC’s mud gun can be either fixed or rotate setup for drilling operators to optimize the performance for the mud gun.

The mud gun can be use in high pressure and low pressure spray action by using different feeding pump.  The high pressure kind of mud gun is smaller design whole low pressure kind  is larger compare with high pressure kind .  The mud gun equip with movable nozzles and mounted on the mud tank with joint and connected with the pump.  It separate the drilling mud in jet form and mixing the drilling fluid in the pool of mud to keep the drilling mud consist mixed.

Mud Gun

The mud gun’s nozzle  is equip either fixed direction or rotated direction. The fixed nozzle is with hydraulic mixing line, the difference is that the drilling mud gun installed the two diagonal, nozzle direction parallel to the vertical tank wall tank. So as to form a can of drilling fluid layer rotation. But in the height direction, the jet effect can be ensured to ensure the convection of the drilling fluid.   The rotary nozzle drilling mud gun is by the input pipe, barrel, crosshead, two curved pipe with threaded joints, can change the nozzle and two coat nut composition, the gun body through the ball bearing and the input pipe is connected with. The drilling fluid through the inlet pipe, a nozzle, crosshead and start at a certain speed to the opposite direction. Speed depends on the drilling fluid pressure, density and viscosity.

GN SB model centrifugal pump converts the input power to the liquid by rotating the liquid by a revolving device – an impeller. Fluid enters pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump.

Centrifugal pump Principle

1. it is important to understand the fact that the pump will pump all fluids to the same height if the shaft is turning at the same rpm.The only difference between the fluids is the amount of power it takes to get the shaft to the proper rpm.

2. We must know that centrifugal pump does not create pressure, it only creates flow. The gauge pressure is a measurement of the resistance to flow.

3. Centrifugal pump’s vertical discharge “pressure-head” is the vertical lift in height – usually measured in feet or m of water

Advantage of GN Centrifugal pump20120414_142207

1. Impeller: impeller plays a vital role in the centrifugal pump, it converts the motor power to the rotate movement and subsequently discharge the fluids .GN centrifugal pumps’ impellers are made of iron.

2. GN centrifugal pump use tungsten carbide mechanical seal to maximally prevent problems, and using the famous brand bearing to assist the shaft

3. In our system, it also be used as feeding pump for desander, desilter and connecting with hopper to mix chemical. Meanwhile, it can be used as trip pump and supercharging pump for rig mud pump.

GN has worked on the solids control units for many years. We have produced a plenty of solids control units including shale shaker, desander, desilter, mud cleaner, mud gun, mud agitator, centrifugal pump, vacuum degasser, mud gas separator, centrifuge and vertical cutting dryer etc. Also, GN is the 1st API certified solids control company in China, also certified by: Europe DNV CE, HSE, ISO9001, Russia TP&TC assure the units quality.
