Tag Archives: High Quality Shaker Screens

Hookstrip bonding shaker screen is a kind of screen which is designed by our country proper development, it is made of two layers or three layers of stainless steel cloth to glue, it without metal plate, the screen cloth according high temperature bonding technology to strong unifies in together. This kind of multilayer structure design increases the strength of shaker screen and using life time. But each screen meshes are different, accurate and reasonable collocation make screening effect is more detailed, it not only can guarantee the enough strength but also increase the effective area in screening process.

Hookstrip soft bonding shaker screen use a coarse mesh screen and a detail mesh screen to bond together. When use it, we should install a network, then the bonding laminated screen is tension. Field tests show that, the using life of this kind of screen can extend. Special to point out, the two sides of super fine screen is not pressed in crochet, so in tension process, the more fine screen layer bears pressure is very small, it is only used as screening layer. This new kind of pressure layer is separate with screening layer is proved is reasonable and the effect is remarkable.

The crudeness or fineness of bonding grid size and bearing layer screen is according need to choose. The upper screen is more fine, the stress layer screen is more fine, the size of grid smaller. Usually the screening layer use 60-100mesh, the stress layer use 30 mesh, when screening layer is bigger than 150 mesh, the stress layer use 40mesh. When screening layer is bigger than 150mesh, the press layer use 60 mesh, in general the grid size is 33mm*25mm*25mm.

Shale shaker is the first level in drilling mud solid phase control system, dispose the mud which carrying large drilling cuttings returned from the well and enter into the second separation equipment. And the main problem is screen replacing, follows are the how to install and correctly adjust the screen.

1.The screen can be used alone, and also can be used duplex and more screen connection. According to users’ requirements to manufacture the inlet mud manifold.
2.Installation and replacement of the screen.

Screen is a more expensive quick-wear part in the equipment, the installation quality is directly influence its service life. Screen adopts bolts tighten device.

Notice: when operation, firstly tighten the right (viewing from discharging sand mouth) makes the screen outboard clamp the limited block which in the bottom of spiral hole, the three bolts should all firstly fix the middle one and make it is more uniformity. The bolt is the dedicated, when replace in the field we must carefully operate and avoid to lose.

3.Adjustment of the screen box dip angle.
When mud displacement is oversize or viscosity is overtop, screen will running mud, this moment we must rapidly adjust screen box dip angle. The size of dip angle is according to don’t run mud o be as the best. The shale shaker screen box dip angle can be adjusted according to requirements, from -1°, 0°, 1°, 2°, 3°, 4°, 5°. When adjust it, first take out the archivierungen, then use lead screw adjust it to make screen box dip angle changed, insert the dowel after adjusted. When screen box works, the mud must filled up above 3/4 of screen surface, if it is not filled up 3/4 of screen surface which is show that screen is too coarse. In order to improve purification effect, we must replace fine mesh screen at this times.
4.The fixed of the screen box in transportation process.

In order to avoid shale shaker damaged in transport process, Notice: the locking lathedog must be locked to make screen box and foundation don’t have relatively vibration in transport process; before start operation we must open the locking lathedog, otherwise will make equipment badly damaged.

5.The maintenance of screen surface.

Before every stop screen, it should be idling 5-12 minutes, meanwhile use pure water wash the screen. Pershift should uses water (summer) or steam (winter) washes screen surface and screen shoe at least. Screen and screen shoe can’t have too much sediment. Especially the mud with the big viscosity, density or use above 60 mesh screen. Otherwise, the viscous materials or after the fine sand is dry up on the screen will blocking the screen holes, when re-start shale shaker will decrease screen filtering effect and must run mud and cause the unnecessary loss.
