 Detailed Introduction of Desander

Features and Advantages:　

KOSUN Desander is the second-phase solids control equipment in drilling fluids treatment. It can be used to solid particles between 45 and 74 in diameter.　　

Desander cones are made from 100% polyurethane and high-chromium iron. It has a lone lifespan. 

Its clamp-on design makes it easy to maintain.　 

It is compact and takes up small footprint.　 

It is flexible to choose 1, 2 or 3 10” or 12” cones based on capacities. 

It is quick to be assembled and installed for users.

     1.Centrifugal Pump outlet and Desander inlet are connected by 6” pipe. 

     2.Desander pipe manifold, whether they are inlet main line or outlet main line, are linked by flange at either end both to allow flow-in and -out of liquid. The joint of overflow main line can rotate at any angle in order to install 8” rubber hose into another compartment of mud tank. Inlet pipe and overflow pipe should form 90° angle when they are installed. 

3.Screen box fixation devices should be turned on before 

    4.Desander can be adjusted via the adjustment of Centrifugal Pump outlet pressure. 

Assembly of Screens 

    1. Screens

Screen lifespan and efficiency will be greatly affected by how well screens are assembled. Try to prevent screen from being artificially damaged. Straighten the screen, or screens will be rapidly worn due to “friction” between screens and supporting strips when shale shaker is working; but they cannot be too tightened, or they will be rapidly damaged or directly torn under over great prestress.When crooked or damaged, supporting strips should be straightened and replaced. 

    2. Slip locking mechanism 

It is aimed at locking screens and tightening winding shaft. Winding shaft can be locked by tightening slip with screw. In order to prevent the mechanism from rusting away, it is better to lubricate it with butter every time when screens are replaced. 

3. Maintenance of Screens:It is forbidden to scratch or slap them with shovel or other iron tools and hard shovel. Apply screens with different mesh based on drilling fluids performances. It is best to use screens with thinner mesh for better efficiency when it is ensured that drilling fluids will run away. 

Maintenance regulations must be implemented on screen maintenance, reparation and cleanup. Failed or damaged components should be adjusted, screwed, lubricated, cleaned, replaced when accumulative working time is above 500 hours. When above 4000 hours. Tightening shaft of screen box should be examined and replaced, taper cylinders and spiral case changed and electric motor insulation property examined.
