A same decanter centrifuge will work differently by different operators. Because the professional maintainence is very important to protect the centrifuge and gives the decanter centrifuge a longer operation life.Following is two reminding for handling GN decanter centrifuges.

• 1)Protect the Centrifuge Bearing before Moving.

GN latest designed decanter centrifuge is fixed with tighten steel bracket belt to support the bowl assemly.Before moving the centrifuge, it is very important to fix the bracket under the bowl assemly by screws and make sure it is tighten enough,if the bracket can not support the bowl assembly tightly,operators can put some rubber on the steel bracket to make the bracket more tightly under the  bowl assembly. And then tighten belt to prevent the rotation of the bowl during shipping from jobsite to jobsite.

2) To start the centrifuge,operators should disassemble the supporting bracket for the bowl, and remove the tighten belt,and rotate the bowl assembly by hand before start to make sure the bowl rotation is free.

3)Lubrication should be done regularly for the centrifuge as following.

If customers have any other questions for your decanter centrifuge,please feel free to contact GN representatives.We will do our best to support you and give you solutions.

GN Solids Control is not only professional solids control equipment supplier, but also supply different mud tanks for different functions. The size of mud tanks range from big mud tanks for oil drilling solids control system and mud plant to mini mud tanks, eg trip tank, sump tank, pill tank etc.

1) Pill tank and trip tank for solids control mud system

Pill tank is used for conditioning the drilling mud by add barite, bentonite or other heavy weight additive.  The size is about 1000x1000x1500mm. The position is placed after decanter centrifuge, fixed on the mixing mud tank. After adding heavy weight additive, the drilling mud can be mixing fully by force from Jet mud mixer with a centrifugal pump.

Trip tank is used for feeding the well when change the drilling tubes. It is generally positioned besides the shaker tank.

Recently, GN Solids Control just offer one sets of 1500HP rig mud system to RG Petroleum.  Pill tank and trip tank is included.

Mud gas separators in other countries also called Poor boy degasser,Liquid-gas separators, Mud/Gas Separators, etc.GN Solids Control  designs and manufactures ZYQ Mud gas Separators. Mud gas Separators is an extremely reliable, vital piece of safety equipment for today’s drilling operations. It is ideal for use where drilling is likely to encounter large volumes of gas, sour gas or when an operator is drilling with an under balanced mud column.

GN Solids Control also manufacture the solar charged electric flare ignition device to matching the mud gas separator to burn the gas.

Solar Charged Flare Igniter

As part of the requirement of the tender drilling contractor are required to provide PT PERTAMINA EP with a supporting letter from GN Solids Control.

GN mud gas separator is to separate gas inside the drilling mud vent to the flare line to burn it in the safe areas.

GN oilfield decanter centrifuges can be used in different applications for handling drilling mud for solids control and drilling waste management.

How to set up bowl speed for decanter centrifuge for drilling mud?

Take GNLW363 serires decanter cantrifuge for examsple, operator can set up the decanter centrifuge speed as following, it can used for following application:

PLC Decanter Centrifuge Speed

• Barite Recovery: Operator can run the centrifuge with G foce at range from 700-1000 G, and run the 14 inch decanter centrifuge at speed around 2000 RPM.
• High Gravity Solids(HGS) Separation:Operator can run the centrifuge with G foce at range from 1000-2000 G, and run the 14 inch decanter centrifuge at speed around 2500 RPM.
• Low Gravity Solids(LGS) Separation:Operator can run the decanter centrifuge with G foce at range from 1800-2300 G, and run the 14 inch decanter centrifuge at speed around 3000 RPM.

How to asjust the speed for decanter centrifuge?

The method to set up bowl speed for decanter centrifuge normally have three ways, one is to USE the VFD control system to adjust the frequency for the motors to control the speed for the decanter centrifuge, second is to use Hydraulic driven system to adjust the bowl speed and differential speed.Third, to change the centrifuge speed is to use different sizes of pulley and belt to change the speed.

GN offers decanter centrifuge for all above types to allow users to use the decanter centrifuges for different applications.

Decanter Centrifuge Feeding Pump speed and capacity.

To feed the GN 14 inch GNLW363 Decanter centrifuge, normaly we recommend to use GNG30-7.5 screw pump.The GNG30-7.5 screw pump is a positive displacement single screw pump, the capacity of the pump depends on the speed or the motor, the motor transfer the speed thru gearbox to the pump.  For example, the ration of the Screw pump is 6/1 so if the pump motor run at 60HZ, that means the motor run at 1750RPM and the pump will run at 291RPM. And if the decanter centrifuge feeding pump run at 291 RPM with capacity at 30m³/h. And if adjust the VFD to run at 30HZ, the pump speed will be half capacity, around 15m³/h.
