Accentuate Your Fashion Trend with Mud Agitator

Shaker deck angle adjustment refers to fig. There are lifter, pipe, worm gear lifter etc. When we make adjustment, handle wheel rotary by clockwise, drilling waste management will be larger; handle wheel rotary by anti clockwise shaker deck angle will be less.

Desilter output angle adjustment can be operated under both running and off condition. When deliver the shaker deck is 0°. While operating, user can adjust the angel according to drilling mud property and flow rate on job site,. If adopt same screen, the higher the angle, the better treating performance and capacity will .

To make Mud Agitator installation and uninstall much easier, GNZS752 designed fast installation structure. The structure is a special type use tension wedge to fix screen. The structure including shelve strip and wedge. The first screen installation, we should inspect the screen dimension, such as 1250+/-2mm, the tolerance can’t over it. After fixed rubber strip, then put screen, shelve strip from shaker back (drilling fluid input), and push wedge evenly on two sides use hammer to push or tension wedges, make two sides identical. Tension each screens subsequently.

Good sealing rubber shale shaker

Shale shaker is the first stage solids control equipment. Sealing rubber is used between shale deck and shaker screen. It plays a very important part for shale shaker performance. A better quality sealing rubber can enable a longer life time of shale shaker and can great reduce the quantity of replacement shaker screen.

Functions of shale shaker sealing rubber

1) Shale shaker is a screening device adjust high vibrating strength to separate bigger particals from drilling fluids. Good quality Sealing rubber can reduce the friction of shale shaker deck and the shaker screen, and provented the shaker from damage.

2) What will happen if there isn’t sealing rubber? If there isn’t screen rubber or it is damaged, the screen frame will touch with shaker deck directly, which will be damaged in a very short time.

3) The worse condition is the dirty mud with many junks from well will fall into mud system directly. It needs the higher treating capacity of the next step equipment. Otherwise it may make damage to the next step solids control equipment, or even worse, it may block mud pump and make stop of the drilling rig.

4) If the sealing of the rubber is not good enough, its anti-corrosion not good enough, it will be broken easily under high temperature drilling mud, and the shaker screen will be damaged very quickly.

In some countires, like in China, Kuwait,Oman, U.S. , Canada, Australia, etc…, shale shaker is usually the only solids control equipment in a mud system. Drilling fluids only treated by shale shaker, then back to mud system for drilling again. In this case, it requrests a high standard for the reliability of shale shaker performance.
Which brand shale shaker can suits such high requirement? See below:

1) Top 1 brand: Derrik FLC 514, Derrick FLC 513 shale shaker

2) Top 2 brand: GN Solids Control shale shaker: GNZS703, GNZS594

1500HP Land drilling rig mud system

1500HP land drilling rig usually match 2000bbls mud system. The mud system will have complete full 4 stages solids control equipment and with 5 steps separation process.

Equipment included in 1500 hp land drilling rig mud system:

1) First stage solids control – Shale shaker GNZS594E / GNZS703E linear motion, 3 each

2) The second & third stage solids control – Mud cleaner GNZJ594E-3S-16N / GNZJ703E-3S16N, 1 each

3) Vacuum degasser GNZCQ360 to remove gas from drilling mud before enters into mud cleaner desander / desilter cone.

4) The fourth stage solids control – Decanter centrifuge, 2 each

One decanter centrifuge GNLW452S in middle speed for barite recovery.

Another decanter centrifuge GNLW363 in high speed to separate the low gravity mud.

5) Jet mud mixing & shearing mixing system, with GN high efficiency centrifugal pump and shear pump for chemical shearing and mixing.

6) 7 each Mud tanks: shale shaker tank, decanter centrifuge tank, suction tank, mixing tank, shearing tank, storage tank 1 or 2 each

Above is the standard 2000bbls mud system for 1500 hp land drilling rigs. GN Solids Control can make customized mud system per user’s special requirements. If you need more information of other size land drilling rig mud system, you can visit GN website or send mail to vivi@gnsolidscontrol.com

Solids control mud gun

Mud gun is usually matched with mud agitator, used to agitating tank corner where the mud agitator cannot work to, and to clean the tank coner. In some cases, Mud gun also used for small tanks no extra space for mud agitator.

GN Solids Control make 3 nozzle mud gun to cover the 360º tank corner. GN is a API certificated company, all its manufacturing per API standard.

GN200 GPM water well drilling mud system

GN 200GPM mud system is suitable to treat capacity between 100~200GPM. It can be used for water well drilling and CBM drilling rigs.

The 200GPM mud system for water well drilling and CBM drilling including below equipment, it is a 1-tank mud system:

1) Mud tank: 4000*2100*1350mm, 1 each

2) Mud cleaner :GNZJ753E-4N, 1 each

The mud cleaner mounted with double deck shale shaker. Above the shaker is a 4-desitler cone assembly.

3) Centrifugal pump: GNSB4x3-11J, (11kw), 2 each, 1 pump for mud mixing, 1 pump for feeding the desilter cone.

4) Mud gun: GNNJQ50-3G, 1 each

5) Mud hopper GNSLM25, 1 each, matched with the 11kw centrifugal pump, to mixing mud for the water well drilling rig.

6) Submersible slurry pump 80YZ50-20(7.5Kw), feeding for shale shaker from mud pit

It is compact design, the whole GN200 GPM mud system with total height no over than 3.5m. And the total width is 2.4m. No equipment need to be removed during shipment. It can be shipped as a complete set in most countries and areas.
