hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located down steam of the shale shakers and degassers, but before the desilters or mud cleaners.
Design Principles:
DC desander is produced by an advanced design, careful engineering, quality materials and finest workmanship which comprising 8, 10, and 12 inches cone diameter. As desanders have varying capacity based on its diameter.
Operation Mechanism:
Desander include two 12-in.(305-mm) diameter polyurethane hydroclones slant mounted over the shaker. Each desander clone includes four replaceable wear resistant polyurethane sections that are joined together with quick release stainless steel clamps. The desander is furnished with an 8-in.(203-mm) diameter feed manifold and a 10-in (254-mm) diameter discharge manifold and a 0-60 psi (4.1-bar) pressure gauge. The desander also includes a solids discharge trough to distribute the hydroclone underflow evenly onto the screening surface.
Tangshan Dachuan Machinery has overcome the disadvantage of the original manufacuture technology, produced a new style hyrocyclonic desander based on the thoery of particle sedimentation.
The characteristics
1. Combined by the 10″ or 12″ swirler and pipes, the operation and maitenance is much easier.
2. Used the abrasion resistant special polyurethane which is corrosion resistant, anti-scouring and has a long life.
3. Put the materials into machine along the tangent line of the inlet hole, the transition is smooth and is in favor of increasing separation efficiency. The separation range is large.
4. The bottom flow hole of hydrocyclone discharges the sand particles as an umbrella and the wet discharging can make the particles be dischaged quickly to avoid the block of bottom flow hole.
5. The symmetrical inlet structure makes the allocation more reasonable and the work stable.
6. The bottom flow hole can be adjusted to control the handling capacity to match the different requirements.
7. According to the clients’ requirements of the handling capacity, the desander can be made up by several groups of hydrocyclone.
