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.

Recent days, DC Solid control package well 100pcs shaker screen and preparing to delivery to Russian. DC Solid control not only can manufacture mud equipment but also design all kinds size of high quality shaker screens.

The order of By Russian is hookstrip type.

The hook strip shaker screen has many advantages. Due to the difference in mesh number of the screen meshes, the user can get more excellent screening effect by using the screen meshes with rational and correct arrangement. The metal lining is designed with different hole size to match with screen mesh of different mesh number.

On the basis of ensuring adequate strength, we strive to obtain the maximum effective area of the screen mesh. Meanwhile, the integration of the bottom coarse wire mesh with small mesh number and metal lining enhances the strength of the whole product and prolongs its lifetime effectively. The grid on the metal lining of the product divides the screen mesh into multiple independent small meshes, which can avoid local damage and excessive expansion. In addition, the product is furnished with special rubber plug which is used for repairing damage. This design can save time and reduce use cost.

All DC shaker screens with the excellent quality, good separating performance, long working lifespan and competitive price,  DC shaker screens are widely used in more than 60 countries。
