Horizontal Spiral Centrifuge Separation Theory

The separation process of solid phase and liquid phase is in the drum. High speed rotary of drum drive the drilling fluid high speed rotary, drilling fluid is left to the wall of the drum for a liquid circle, because the solid phase in the liquid circle is suffered the centrifugal force which is hundred and thousand times bigger than its own gravity, it overcomes the resistance of drilling fluid viscosity and rapidly sediment to the inner wall of drum and forming solid phase, liquid form liquid phase. The ratio of the solid phase centrifugal force and it own gravity is called the separation factor of centrifuge.

Pushing slag work of Horizontal Spiral Centrifuge is completed by screw propeller, in the function of differential mechanism, screw propeller and the drum form a certain speed difference, then the solid phase particles are precipitation to the drum inner wall are scraped from the wall of the drum, it is pushed to the small end by spiral impeller, in the process of propulsion is dehydration, at last get to disilting nozzle.

Maintenance Methods of Drill Cuttings Dryer

Drill Cuttings Dryer is the core equipment of drilling waste treatment system. Like any other type of equipment it requires regular maintenance and servicing. when we operate the Drill Cuttings Dryer, the is often the problem is that so there are some maintenance methods of Drill Cuttings Dryer as follow:

1. If there are more leakage from Speed Reducer of Cuttings Dryer, please check and do it as follow: If the joint surface of Worm Speed Reducer case cover is not closely sealed, please scrape it; 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.

2. 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.

3. 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.

4.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.

5.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.
