GNPS70-3S features

1. GNPS70-3S Shale shaker is designed as double motors in-phase principle. The shale shaker will vibrate as elliptical, part of spare parts are interchangeable with international shale shaker

2.  Adopts advanced vibration motor, reliable operation, run long time without any problem

3. The shaker screen can be flat type or pyramid type. Shaker deck can fix 3 pieces screen and make screens as different combination.

This will lead screen take longest usable life. According to different drilling mud the screen mesh will be 40-200 mesh

4.  Screen is tensioned by wedge, this is more convenient and reliable

5. The shale shaker deck can be adjusted. Adjustment will be realized by adjusting worm whirl. There is worm whirl at each side of shaker deck. Middle shaft connect two whirl pipe, when we make adjustment, two sides will be compliant and in-phase

6.  The paint of shaker is processed by grit blast, use high anticorrosive zinc rich coating. Will make shaker surface anticorrosive and more beautiful

Main operations on GNPS70-3S

1.  Shaker screen selection

GNPS70-3S shale shaker can fix different meshes screen. This equipment can use 10-200mesh screen. Usually, when the shale shaker is first stage solids control equipment the shaker screen can be 30-100mesh. When the shale shaker is a part of mud cleaner, the screen can be 80-200mesh.

Shaker screen selection can among manufacturer engineer, user, and contractor discussion. Replacement screen should be selected specially from manufacturer

2. Replace shaker screen process

To make screen installation and uninstall more easy, GNPS70-3S designed fast installation structure. The structure is a special type use tension wedge to fix screen. Refer to fig IV. The structure including shelve strip, wedge. The first screen installation, we should inspect the screen dimension, such as 1050+/-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.

Shale shaker screen replacement, during operation, when screens broken or need to be replaced , please refer to fig IV. Get wedge out, then bring out screen, check if rubber strips are sufficient; then put new screen on shaker deck and tension it steadily. The replacement is finished

3. Shaker deck angle adjustment

Shaker deck angle adjustment refer to fig V. There is mainly bracket, pedestal, elevation whirl worm, elevation nuts, etc. When we make adjustment, handle wheel rotary by clockwise, shaker deck angle will be larger; handle wheel rotary by anti clockwise shaker deck angle will be less.

Shale shaker output angle adjustment can be operated under running and off. When finish the shaker deliver it, the shaker deck is 0°.

When user operate shaker, according to drilling mud property and flow rate on job site, and adopts same screen, the angle is higher, the treating performance will be better while treating capacity will be higher. When drilling fluid is leaking on shaker deck, increase deck angle can get rid of fluid flow away

GNPS70-3S for GNPJ70-3 mud cleaner

GNPJ70-3 combined GNPS70-3S, Desander cone, Desilter cones as well. Thanks to the BEM vibration type make this mud cleaner more effecient. If the two equipments configured in one system, this will save much time and provide more convenience on spare parts replacement, such as shaker screen, etc.

This type shaker and mud cleaner provides users ideal solution and economical cost. It will save drilling cost or decrease more investment also
