Like oil drilling fluid solids control equipment desander, desilter also is a combination of desilter hydrocyclone and shale shaker screen. The polyurethane is used for hydrocyclone. The lower little shale shaker is elliptical. The vibration generator is driven by vibration motor, which makes the screen box keep a integral forward elliptical motion.
Hydrocyclone Desilter
KOSUN desilter is used as the 3rd stage of solids control equipment for drilling mud, which make separations between 15 and 45 microns.
1. 100% Polyurethane used as the material of desilter cones to extend its service life
2. Clamp type for easy maintenance
3. Compact design with small footprint.
4. flexible options of the number of the cones(8,10,12,16)used for different capacities.
5. Flexible fast connection are available for user assembly.
Desilter Hydrocyclone
Operating a desander ahead of the desilter takes a big load off the desilter and improves its efficiency. Operating desilters at peak efficiency is much the same as operating a desander. Here are a few fundamental principles to keep in mind.
1 Operate the desilter at the recommend pressure 32 – 40 PSI.
2 As solids increase, the cones bottom can be opened slightly to help increase solids removal.
3 Check cones regularly for bottom plugging or flooding, since a plugged cone allows solids to return to the active mud system.
4 If a cone bottom becomes plugged, unplug it with a welding rod or nail. If a cone is flooding it may need to be adjusted or the feed may be partially blocked off. It should also be inspected to make sure the cone is not worn out.
5 Run the desander continuously let fluid overflow back and process over & over.
6. Maintenance: A desilter’s smaller cyclones are more likely than a desander’s cones to become plugged with oversized solids, so it is important to inspect them often for wear & plugging. This may generally be done between bores, unless a failure occurs. The feed manifold needs to be flushed & checked for debris between bores.
