Centrifuge for is fourth phase oil drilling rig fluid solids
control equipment. Mainly separate particle sized 2-7microns. Drilling fluid
decanter
centrifuge has got large development on both structure and functions.
Especially there are many manufacturers design centrifuges according to
drilling mud features or property. Then the centrifuge become many models and
types used in various drilling projects.
Always there is a screw pump or submersible pump to feed the mud to Decanter
Centrifuge. After the drilling fluids being fed into the centrifuge drum, under
the function of centrifugal force, solid phase particles are pushed to the
internal wall of the drum, then to the solid discharge export of the small end
of the drum and excreted. While the fluids is excreted from the overflow hole of
the large end.
Especially, KOSUN Solid
control combines abroad advanced technology and our unique design to
developed the most cost-effective drilling fluid centrifuges. Recent years, our
superior quality centrifuge and lowest line price had been recognized by more
and more users.
KOSUN Decanter Centrifuge units are supplied with advanced controls for both
variable speed bowl and scroll back-drive optimization making them easily
configured to produce a wide range of sludge dewatering results. KOSUN decanters
are very easy to set up while being extremely robust, stable, and reliable in
everyday use, without the ease of use detracting from the quality of the
operating results.

Selection and maintenance of vertical cuttings dryer retarder
Selection and maintenance of vertical
cuttings dryer retarder:
1. For the first time, replace the oil after one-cycle operation. And replace it every 3-6 months later on. If the temperature goes too high or too humid, remember to shorten the period and to add oil.
2. Retarder is not lubricated when leaving the factory, so users should add enough lubricating oil until it reaches the designated height by oil standard.
3. When impact load is too much or startup too frequent, users should accesorize positioning pin or hydraulic coupling between base and footing, or demand a positioning slot or positioning plane upon the base.
4. Users should make it clear when placing the order if retarder output shaft should be installed upwards and negotiate over designing lubricating system.
5. Horizontal and lateral retarder should be installed about 15° inclined.
6. Vertical and luffing retarders adopt pump reciprocating lubrication. When input power is
7. It is regulated that retarder should use N220 industrial gear oil(horizontal one uses N150 gear oil), lubricating oil should comply with.
8. After installation, the input shaft of retarder should be rotated flexibly by hand and output shaft rotated by 360°, the resistance felt everywhere should be the same, and lubricating oil should be added to the designated height by oil standard. Then, connect the power to allow it run without load for 1-2 hours and increase load bit by bit if everything is alright.

Oil leakage management measure of vertical cuttings dryer
Oil leakage management measure of vertical
cuttings dryer:
I. Reparation: Take some as examples, scrape it if the joint surface of Worm Speed Reducer case cover is not closely sealed. Repair the tubing flare when oil leakage occurs at the tubing connection due to unfit bell mouth. Sometimes burrs, scratches and deformations of hydraulic lubricating control system components can cause external or internal oil leakage. If not serious, it can be eliminated by reparation. In drilling waste management, these error is not allowed.
II. Fastening: Fasten the screws, nuts, connection points, etc. at the leaking place to eliminate the leaking phenomenon caused by loose connection. During the process, examination should be implemented on fastening situations of all connection. For daily maintenance, operators must also be aware of this point. They are supposed to fasten immediately once loose parts are discovered so that oil leakage or other unexpected problems and accidents will be avoided.
III. Replacement: Replace them when it is found that oil leakage in speed reducer is caused abrasion on seal elements and unreparable damage on relative components. And remember to match the replacements and the opposite parts properly so as to prevent new oil leakage problem from following the old.
IV. Dredging: It is a vital oil leakage management measure to ensure a smooth return oil passage. Enlarge the oil hole promptly, remove the sewage, do dredging or add new return oil hole tubing when it is found that the holes are not large enough, structure not reasonable and tubing blocked by sewage. A smooth oil passage will greatly reduce the chance of lubricating oil leakage.
V. Sealing coating: As for pipe joint, use sealing adhesive to seal at the box seam to eliminate seep. Sealing coating method has the advantages of simplicity, remarkable effects, cheap costs and extensive adaptability. Usually, 70%-80% of equipment can be coped by different sealing coatings when it is leaking oil.
VI. Retrofitting: Somtimes it is necessary to improve sealing materials, change fastening methods, replace lubricating agent, adjust return oil position, modify pre-leakage measures, etc in order to resolve the leakage problem. Retrofitting can take many forms. Generally speaking, it should be remembered not to affect the normal operation nor the original strength and rigidity of machine, especially by adding return chutes, enlarging screw holes, attaching oil dripping pans, etc.
VII: Adjustment: Reduce system pressure, adjust sliding bearing, narrow the gap between shaft hole and journal by adjusting the oil pressure of hydraulic lubricating system so as to avoid leakage caused by too much overflow. Overcome the leakage problem resulted from its failure by means of adjusting oil scraper like loosening, tightening, raising and lowering the felt. What is more, it is the best to adjust at first and then take some other measures based on the proper matching of relative components.
