Shale shaker screen maintenance
Shaker screen is an important part of solids control system. It is widely used in oil & gas drilling works. Aipu can produce various of shaker screens，including flat type, corrugated type, the hook strap type, the wedge blocked type, the steel frame and composite frame ones. Shaker screen as a wearing part, in order to save cost, first we must know some maintain methods on shaker screen.
The shaker screen can be used alone or have two or more combined to be installed on screen box according to the users’ requirements.
Screen cloth is an expensive wearing part for this equipment, the quality of its installation will directly influence its service life. A bolt stretching device is adopted to fix the screen cloth. The dip angle of screen box is adjustable to reduce shaker screen wear.
The regulating of the screen box’s dip angle
When slurry discharging quantity is too much or escaping because of a higher viscosity, the screen box’s dip angle should be regulated. The best dip angle is that one preventing slurring from escaping. The screen box’s dip angle of the facility can be discretionarily regulated by the valves including -1°, 0°, 1°, 2°, 3°, 4°, 5° according to actual situation.
Fixing screen box during transportation
In order to prevent any damage during transportation, please remember: the locking yoke should be tightly locked in transportation, making sure that there is no relative movement between screen box and pedestal. The locking yoke should be unlocked before its starting, otherwise, the machine will be seriously damaged.
The maintenance of shaker screen
The screen should be idly operated for 5~10 minutes before stopping operation every time and the sieving medium should be cleaned with clean water at the same time.
The shaker screen and its stand should be cleaned by water (in summer) or vapor (in winter) at least every shift. There should not be too much sediment on the screen and its stand, especially when the viscosity or density is high or the screen mesh is thinner than 60. Otherwise the sediment on the shaker screen will block the meshes when dried, and the efficiency will be greatly impact its later operation, causing unnecessary escapes of slurry.
Aipu solids control cater to different users’ demand to design and produce various different types screens accordingly. We mainly focus on international market. Since our screens can meet strict requirements from overseas clients. If you are interested in shale shaker screen or need it, please call us at any time.
