Last week, GN engineer came back from a jobsite at Middle East, he brought back not only valuable feedback from the end-user and important data for jobsite commissioning, but also, more important for us, the customer’s trust for GN and their future cooperation plan with GN.

As sales of GN Solids Control, my colleague and myself, are very happy to received a huge bag of gifts from my customer. To us, they are not only gifts, but also, the sign for their satisfaction of GN high quality products and GN reliable technical support. They are indeed the approval of our work.

This customer is a powerful drilling waste management service provider in Middle East, they have projects all over middle east, and they have their own producing ability for all parts used in their package, except for high speed decanter centrifuge. This time, they purchased 2 sets of GNLW363BG-VFD decanter centrifuges from GN, as their boss said when signing contract with GN” we only focus on Top Quality products”.

Detailed Data of GNLW363BG-VFD:

1. Most popular VFD control panel, positive pressurized control panel for 3 VFDs for centrifuge main motor, back motor and centrifuge feeding pump.
2. Adjustable speed from 0 to 3200RPM, suitable for many applications. Nearly all applications during solids control and waste management.
3. Genuine SKF bearings to ensure a longer service life and special method during transportation for protecting the bearing.
4. Easily adjustable liquid discharge ports for changing the drying degree of separation.
5. Impeller and solids discharge ports protected by tungsten carbide tiles, for anti-wearing.
6. SS2205 Duplex Stainless Steel for main body of rotation bowl.
7. ABB, Schneider and Siemens brands electric parts.

In a word, GNLW363BG-VFD is an ideal choice for their jobsite.

And this time, GN sent chef electric engineer to their jobsite for first time commissioning. They commend GN’s engineer as” a professional engineer and an esteemed person”. They spent a good time during the successful commissioning.

GN Solids Control deserves the trust of valuable customers.

Mud agitator, as an auxiliary equipments in solids control system and main equipment for mud plant, plays an important role in drilling mud tanks. It helps the drilling mud in tank to be evenly mixed and avoid from sedimentation.

Normally, there are two types of mud agitators:

1. Vertical type mud agitator:
2. Horizontal type mud agitator:

 

Advantage and disadvantage of Vertical Type Mud Agitator:

In structure of vertical type mud agitator, the gear box and motor are vertically connected with each other, motor is located on top of gear box. When it is installed on tank, it occupies less space than the horizontal type mud agitators. But comparing with horizontal type mud agitator, it is a bit complicated for maintenance and repair.

Advantage and disadvantage of Horizontal Type Mud Agitator:

Comparing with vertical type mud agitator, this horizontal mud agitator need more space on tank top. But also because of the horizontal location of motor and gear box, both of which are installed in same level of surface, it is easier to maintenance and repair.

Recently, the horizontal solution is more popular in usage.

GN Solids control, as the 1^st API/ISO/CE/HSE Certified solids control company in China, focuses not only on main equipments like centrifuges, shale shakers, vertical cutting dryers and etc, but also for auxiliary equipments like mud agitators. This year, GN has designed and put into production the new generation of mud agitators, the 3^rd generation horizontal mud agitator, which sure will proved more efficient.

Comparing with fixed speeded Decanter centrifuge, clearly VFD controlled decanter centrifuge have its own advantages like easily changeable rotating speeds per site condition and mud condition. But also, in a comparably stable condition jobsite, when a certain speed is decided, a fixed speeded GNLW363BG Decanter Centrifuge also has its own benefits。

 

Common advantages for GNLW363BG (Fixed Speed) and GNLW363BG-VFD Centrifuges:

1. High speed centrifuges, GNLW363BG-VFD has a speed range from 0 to 3200 RPM, while for fixed speeded GNLW363BG Centrifuge, determined speed is 3200RPM.
2. Best materials like SS2205 for rotation bowl and tungsten carbide tiles for impeller protection, also tungsten carbide solids discharge ports for both GNLW363BG Fixed speed and VFD.
3. Top quality bearings, SKF bearing original from Germany.

Briefly speaking, for centrifuge itself, GNLW363BG and GNLW363BG-VFD are totally the same, only differences are of electric control panels. For VFD control panel, GN Solids Control adopts positive pressurized VFD control panel, which is world widely popular.

Benefits for GNLW363BG FIXED SPEEDED

1. Easy to operate, because speed already decided per jobsite condition, no need for the operator to learn how to adjust the rotation speed.
2. Small space required by fixed speed control panel. The fixed speed control panel can be installed on centrifuge base frame, which occupies less space.
3. Fixed speed model saves more money than VFD model.

Fixed speed means only 1 speed for option?

Of course not. For fixed speed GNLW363BG, GN can provide customer extra pulley and belt sets for reaching other requested speeds, like the designed speed is 3200RPM, and extra speed 2500RPM and 1800RPM available.

High Fixed Speed May Cause Damage to Machine?

Of course not. In somebody’s eyes, a sudden high speed will do damage to machine or motor. But GN engineers have already taken this into consideration. They use hydraulic coupling for fixed speed centrifuges to solve this problem.

May you need centrifuges for high speed or middle speed, fixed speed or VFD, 14 inch bowl or big bowl, you can consult to us, we have several options for you.

By end of next month, September of 2014, GN Solids Control’s new factory will be started. This is the 4^th factory GN owns. And this factory will play an important role in GN production line.

Since its establishment in year 2007, GN grows from a single factory company to today’s top manufacturer of solids control and waste management company in China. It owns 4 factories: old factory in city of Tangshan, new factory near Beijing, a separate factory for shaker screens and the above mentioned one, a new factory with office building and workshop.

GN’s core product decanter centrifuge will be moved there and production capability will be doubled soon. Besides decanter centrifuges, GN Solids Control will establish a separate workshop for centrifugal pumps.

Recently, orders for centrifuges come from everywhere in the world. Some old customers even complain that GN never has in-stock centrifuges. GN is sorry about that too. For each lot of under production centrifuges, before production finished, all are sold out. The new factory will solve this problem for GN Solids Control, this is no doubt a good news for both GN staff and GN valuable customers.

For the new factory, GN will continue its high standard for quality control and advanced technology used for precise products. And GN is always willing to do better in providing the customers and end users with most suitable solutions and highly efficient equipments.

One of the most current vision of GNZJ Mud Cleaners and GNLW decanter centrifuges was shown at OTC 2014 in Houston, USA. This can be the third time that GN brings the solids manage gear for the show. Not only the solids handle gear is improved and upgraded, but moreover GN established a Houston based American branch firm to provide nearby warehouse and soon after sales service to American market place.

Mud Cleaner and Desilter at OTC 2014

GNZJ-703E-2S12N Mud Cleaner is usually a mixture of 1 unit GNZS shale shaker, two sets desander Cone and 12 sets Desliter Cone utilizing a all round capacity of 240m3/h(1056GPM).

GNLW553-VFD is generally a major bowl massive volume decanter centrifuge specially designed for quickly processing operation with VFD and PLC manage method.

GNLW363-VFD is GN most well-known decanter that is certainly typically installed inside the active mud tank system for control the viscosity inside the water primarily based drilling mud.

GN Solids America Solids Deal with Gear warehouse is 30 munite drive from OTC Exhibition Center, many the prospects possess a check out there to sea the shale shaker, mud cleaner, decanter centrifuge, shale shaker screen. Later GN will fill in much more as inventory which contains centrifugal pumps, solids control spare parts and so on.

GN believes GN Solids America LLC will enhance GN’s US & Canada solids control sales.
