In the oilfield drilling, decanter centrifuge is used frequently and is necessary to effectively separate solids particles in the drilling fluids. Decanter centrifuge is also called horizontal screw discharge sedimentation centrifuge, is the special solids control equipment of solid-liquid separation, designed by the characteristic of drilling fluid. It can accomplish each procedure of feed, centrifugal sedimentation, unloading, etc.

How to keep decanter centrifuge working well in drilling solids control ?

1. Centrifuges to be installed on top of the new entrance to the tank away from the drilling pump, can also be arranged according to the actual situation.

2. Frequently check the fasteners are tightened, and lubrication of lubricating parts.

3. The top-long centrifuge should be cleaned rollers and conveyor to have a confirmation no jamming before boot.

4. Machine operation should idling for 10-15 minutes, confirm centrifuge normal operation, then open the pump for a small to large amount of slurry, adjusted to a suitable date.

5. If the drilling fluid viscosity is too high, should be appropriately adding dilution water, to reduce viscosity, to accelerate the solid phase precipitation speed, improve the processing capability of the centrifuge.

6. All safety protection guards shall be installed before starting up. It is forbidden to open the guards of decanter centrifuge to observe the running state of the machines.

7. During the operation of the decanter centrifuge, don' t touch the moving parts and rotation parts.

8. It is forbidden to brake in any way before the decanter centrifuge is stopped.

9. If there is abnormal noise and vibration, close down decanter centrifuge immediately and make troubleshooting.

10. It is forbidden to have the decanter centrifuge running at the rotating speed out of active speed that indicated in the instruction and nameplate.
