Points of appling drilling fluids decanter centrifuge

The decanter centrifuge is mostly employed for the separation between solid particles and liquid in the suspension. The horizontal decanter centrifuge is commonly utilised for the chemical business, petroleum market, food industry, medicine industry, mineral processing industry, coal industry, water remedy, ships business, and so forth.

Points of appling drilling fluids decanter centrifuge:

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.

The drilling mud decanting centrifuge is installed on top of a relatively taller mud tank. The drilling mud from bore hole flows through shale shaker, desander, desilter and was transfer to the decanter centrifuge to remove the find solids particles in it. The mud after the treatment of the decanter centrifuge are considered to be clean and can be reused back to the drilling hole.

The centrifuge may be chosen according to the size and concentration of the strong particles within the suspension liquid or the drilling flare ignition device, density contrast of two liquids, the viscosity of the liquids, the qualities regarding the residue or the sediment, coupled with the separation requirement, at the same time, the requirements concerning the moisture content materials about the residue or the sediment and the clarity of the filtering liquid as well as the separated liquid will be taken into consideration to decide the choice of the centrifuge.
