There are some basic steps to operate an oilfiled centrifuge ,here GN solids control a specilised centrifuge manufactrue list some for your referenc,to help your centrifuge work stable for longer time.

1 Adjustment of the rotation speed of bowl

The rotation speed of bowl is only allowed to be adjusted within the maximum active rotation speed specified in the specification or on the nameplate of the centrifuge.

For rated frequency centrifuge, change the main pulley with bigger or smaller diameter and longer or shorter V-belts as well to increase or decrease the rotation speed of bowl.

When the operating speed of rotating bowl is increased, smaller solid particle can be separated but the throughput will be reduced, the abrasion, vibration noise and load will be increased and the service life will be shortened.

Hence, it is recommended to rationally select bowl speed according to separation application or solid content in drilling mud. For example, select medium/low speed for recycling barite or high density slurry, select higher speed for medium density slurry, and select the highest speed for low density slurry.

2 Adjustment of differential speed

The differential speed of centrifuge is generally within the stipulated range and need not to be adjusted by customers. However, customers can only change this parameter within a small range by themselves.

Excessively high differential speed may result in turbulence of fluid flow, disturb solid deposit and reduce slag discharge; while excessively low differential speed may cause conveyor blocked.

3 Adjustment of pond depth

Dismantle the 4 dams on the big end semi-shaft, reassembly with a new same angle, and the overflow diameter is consequently changed. When the overflow diameter increases, the pond depth will decrease, and vice versa. Under the condition that the speed of bowl and the differencial speed is definite, if the pond depth decreases, the moisture of discharge solid will decrease, the torque moment on screw conveyor will increase; contrariwise, the recovery ratio of solid phase will increase.

4 Adjustment of V-belts

Checking to see if the triangle rubber belt is appropriately set up is imperative. If applicable, to loose the bolts of motor control, adjust the screw to properly fasten the triangle belt, and finally re-tighten the bolts. In the process of adjustment, to align the active wheel with the passive wheel is a must.

5 Adjustment of overload release and electric interlock

The distance between the roller and the drive plate should be appropriately adjusted. If the distance is excessive long, the electric protection will fail to function; if it is excessive short, the roller and the limit switch can easily be damaged.

After each action, the drive plate and the coupling should be reset. The safety pin, the roller and the limit switch should be inspected and replacement should be performed for any damage.
