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.

Centrifugal pump is most important conveying device in a oil and gas drilling mud solids control system. Main structure and parts of centrifugal pumps are impeller, pump cover, guide wheel, shaft, bearing, sealing devices and etc.

1. Impeller: impeller is the most important part of centrifugal pump, it transfers the generator’s energy to the liquid. Most centrifugal pumps’ impellers are made of iron.
2. Pump cover: pump cover is used to guide the liquid flow from impeller, as the flow cut is gradually larger and larger, the liquid flow’s speed smoothly lowered. Then dynamic energy turns into pressure. Besides that, pump cover guides the liquid to outlet pipe.
3. Guide wheel: guide wheel is installed on out edge of impeller and fixed on pump cover, its main function same as pump cover.
4. Sealing devices. In order to make sure the efficiency of centrifugal pump, there should be insulation from inside liquid and outside air. GNSB centrifugal pumps use mechanical sealing for better performance.

GNSB Series centrifugal pumps are one of main equipments GN Solids Control produce. In near future, GN will arrange a separate workshop especially for centrifugal pump production. GN centrifugal pumps’ spare parts are interchangeable with some world famous centrifugal pump. Each year, GN sells tens of systems with hundreds of centrifugal pumps. Besides that, GN also sells such pumps separately.
