KOSUN drilling fluids desander’s daily maintenance

The mud desander is the two-level solids control equipment used for drilling fluid treatment. The desander and desilter is mainly used for separating those solid particles with the granularity of 47 to 76 microns in the drilling fluid. Structure of desander
Here are several unmissed points on desander’s daily maintenance:
1. No butter should be applied insider its hydrocyclones and seal groove cavity on the top since they are sealed by metal which will be damaged by the potential particle content or fixture from butter.
2. Spare filter element and adequate O-shape sealing ring should be fully prepared.
3. Visual inspection should be conducted into its hydrocyclones.
4. Indicated value displayed on pressure differential gauge should not surpass 3MPa when it is working.
5. Only one hydrocyclone is rolling while the other one is saved for later use.
6. Six-hourly examination of wall thickness should be carried out on key parts of desander.
7. A sudden fall of pressure differential indicates damaged filter element. In this case, one hydrocyclone should be shut and another one started.
8. Filter element should be taken out and examined after one day finishes.
9. The butter from screw thread should be prevented from blocking desander filter element. If blocked, it should be moved from machine and cleaned by high-pressure steam.
10. The moment the filter element is moved from machine, it should be cleaned by water at once to avoid precipitation of sand or support agent at essential points.
The desander features:
a. Adjustable swirler underflow The swirler underflow can be adjusted by changing the swirler nozzle.
b. Long service life The material of the swirler is polyurethane,so the swirler is wear resistant,light weight,corrosion resistant,and not easily aged.
c. Easy to use The mud cleaner can use be used desander unit and shale shaker combination，or desilter unit and shale shaler combination,or desander unit,desilter unit and drilling shale shaker combination,or just the shale shaker only.
d. Compact structure
