In order to meet with today faster drilling requirement, we keep improving the drilling fluids design including bigger capacity of decanter centrifuge, high capacity shaker with unique shaker screen design and streamlined process. Under this situation, GN displays a series of solids control equipment including shale shaker and decanter centrifuge.

 

GN Vibration Screen Shaker

 

GN drying Shakerwas designed with a two-motor system that can operate the linear motion mode, allowing the operator to tune the G-force down and up depending on the drilling fluids conditions. It provides operator flexible way to make the adjustments based on the condition and volume of drilling fluids across the shaker surface. The shaker can behandled with high G-force for highflow rate but can be turned down to a less vibrating mode for cutting solids flow and volume.GN shakers were recently deployed to many drilling site.

 

GN Solids Control Decanter Centrifuge

GN offers different size decanter centrifuges including 14inch 18 inch and 22 inch. We have more than 30 sets 14 inch bowl decanter centrifuge working in the Nigeria, more than 20 sets of 14 inch bowl centrifugein the Argentina.GN decanter centrifuge provides the most reliable working performance for oil and gas drilling industry. Regarding to different requirement, we also have different model to deal with.

1. Barite Recovery.

 

We utilize either GNLW 452（18 inch） under the 1800RPM or GNLW 363(14inch) under the 2200 RPM to recovery the barite.

 

2. Generally Solids Control or High Gravity Solids

 

We use GNLW 452（18 inch）or GNLW 363(14inch) under the 2700 RPM to recovery high gravity solids. Typically, we also use GNLW 363(14inch) under the 2700 RPM matching with GN vertical cutting dryer for waste management

 

3. Low Gravity Solids

 

We normally utilize the GNLW 363(14inch) under the 3200 RPM which effectively remove solids

 

If you have any solids control issues, please feel free to contact with me.

Hebei GN Solids Control Co., Ltd is the first API certified solids control company in China. This year, GN has made many a solids control system such as one 1000 GPM for COSL, drilling waste management system such as one for GWDC to do service for Shell and four for Baker Hughes in Russia, and also mud system for various drilling. Last month, GN has delivered one set of TBM mud system to its Singapore customer. As introduced before this mud system has a dewatering unit, but in this blog, delivering unit will be introduce briefly. Different from using screw conveyor to deliver solids to a vertical cutting dryer to handle in a drilling waste management system, belt conveyor is used as delivering system in the TBM mud system delivered last month to Singapore.

 

GN provides supplier one-stop service, so GN also outsources some equipment to finish its project and to provides one stop service. Regarding to the TBM mud system delivered to Singapore,  GN purchase the belt conveyor form other suppliers to provide the customer the completer and considerate service. And here I’d to share the usage scope of the belt conveyor briefly after translating the user manual into English.

 

With high delivering volume, simple structure, easy maintenance, low cost and universal usage, TD 75 fixed belt conveyor is usually in metallurgy, coal, transportation, electric-water industry to convey material in power. According to delivering requirements, it can be used singly. Also, a horizontal or slop delivering system can be formed with many a TD75 or with the combination with other equipment.TD 75 is usage temperature is between +40℃ to -10℃, and the material should be below 50℃. Measures should be taker for special requirements such as explosion -proof, anti-water, anti-corrosion, heat withstanding and coldness withstanding

GN solids America is a China based manufacturer of solids control equipments and drilling waste management equipments but with sales office and warehouse in Houston, TX. Our main equipments for solids control including:

Shale shaker( 3 panels or 4 panels, linear motion), mud cleaner(also called 3 en 1 or mud conditioner), desander ( with underflow shaker or without, desander cone 1pc, 2 pcs or 3pcs), desilter (with shale shaker or without, desilter cone 4inch 8pcs, 12pcs, 16pcs for option), vacuum degasser, poor boy degasser, mud agitator, mud gun, centrifugal pump replacable with Mission pump, shear pump for jet shear unit, mixing hopper, screw pump( NETZSCH brand in Germany), slurry pump, etc.

Our main drilling waste management equipments including:

Vertical cuttings dryer, decanter centrifuge, hi-G dryer shaker, screw conveyor, dewatering unit

Screw conveyor is also called Auger which is used to collect and transfer the drill cuttings from the shale shaker to vertical cuttings dryer or cuttings collection box for further treatment. For better operation and maintenance of GN screw conveyor, the following instructions should be followed up:

1 GN standard screw conveyor is composed of 12ft length each section, 2 section, 3 sections or 4 sections for choice. At the end of each auger, there are 2 bearings, which should be lubricated regularly. There is suspension bearing at the end of each section, which should be added grease every 2 weeks.

GN provide options of screw diameters for 12inch, 14inch, 16inch and 18inch.

2 Gearbox is installed at the end of the screw conveyor, it should be lubricated every 6 months according to the operation instructions.

3 The screw conveyor should be installed properly and carefully when it arrived at the jobsite, then placed correctly and tighten the anchor bolts.

GN solids America has professional engineer team in Houston for immediate trouble shooting, pls call us at 713 320 3868 for emergency service.

Fixed speed centrifuge is popular with some customer in tight budget. This kinds of centrifuge is not that easily to use when you shift between different projects with different material property, or when the treating material property change and require centrifuge working with different speed. Why say like that?  Because it takes some time to change belt pulley to get different bowl speed. If the user is familiar with the process on belt pulley change, it may only takes 2-3 hours; However, if the user is not familiar with process on belt pulley change and lacking of some necessary tools, things may be harder and it may takes some days to find the necessary tools first and then, you can done the job.

1) What we need to change belt pulley for GN fixed speed decanter centrifuge

In order to service the customer better, GN Solids Control will offer one tools box containing some necessary tools for centrifuge operation and belt pulley change. The tools including but not limited to below items:

Spanner/Wrench, Grease gun, Screw nuts and screw pine, Tape, Pine wrench, Puller, Drilling Waste Management System, Arm crane Etc.

 

2) The process to change the belt pulley

 

Firstly, we need to release the main motor and put it close to the auxiliary motor;

Secondly, we need to disconnect the rubber connection between auxiliary motor and conveyor;

Thirdly, we need to remove the belt pulley with the coupling;

Fourthly, we need to disconnect the belt pulley from coupling;

Fifthly, we need to put the new belt pulley on the coupling

Sixthly, we need to put back the belt pulley with coupling back to the main motor.

Then, reverse the process one step by one step.

 

The best way is to learn the process from the manufacturer. Different manufacture with different design of centrifuge; GN Solids Control can offer jobsite service if customer request. And also, the customer can come to GN factory to learn about it.
