When the centrifuge is working, the drilling fluid enters the centrifuge through the feed pipe, and then is accelerated on the conveyor shaft barrel and flows into the drum through the feed hole in the shaft barrel. Due to the extremely high rotational speed of the cylinder, under the action of centrifugal force, the particles with large density or volume are thrown to the inner wall of the cylinder, so that the solid-liquid phase is separated. The solid is sent to the small end of the drum by the conveyor and discharged through the bottom flow port; The fluid containing fine particles flows in the opposite direction to the large end of the drum and is discharged from the overflow port. The thickness of the liquid layer in the cylinder is controlled by adjusting several overflow holes on the centrifuge face. The conveyor can continuously push the settled solid particles towards the small end. When moving to the transition zone of the dry and wet zone of the centrifuge, due to the role of centrifugal force and extrusion pressure, most of the free water is squeezed out, and the adsorption water is mainly left on the surface of the particles. Most centrifuges in the field have a capacity of 40-60m3/h
Note:
- Before starting the machine, remove the debris that affects the operation of the centrifuge and check the fastening cover.
- Rotate the main motor pulley and auxiliary motor pulley by hand, if there is a blockage phenomenon should be eliminated in time; Check whether the motor running direction is consistent with the indicated direction.
- Turn on the power switch, start the auxiliary motor first, pay attention to the normal operation, and then start the main motor, if there is an anomaly should stop to check and eliminate it.
- Open the inlet valve and start the liquid supply pump to supply liquid to the centrifuge. If there is no abnormality, the diverter valve should be gradually closed until the full flow. If the centrifuge load is found to be too heavy, the diverter valve can be opened appropriately.
- When the solid phase discharged from the centrifuge sand discharge tank is too dry or too wet, the overflow baffle or liquid intake can be adjusted.
- When you need to stop, first turn off the motor of the liquid supply pump.
- Start the motor of the cleaning pump, and open the valve to clean the inner wall, outer surface, and sand discharge tank respectively, and the cleaning time shall not be less than 60 seconds. (If there is no cleaning pump, it can be cleaned directly with the website water source.)
- Turn off the motor of the cleaning pump.
- Turn off the main motor and turn off the auxiliary motor after 2 minutes.
