A mud cleaner is a combination of desander and/or desilter mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone ( desander and/or desilter ) to separate particles and the underflow passes to the fine screen mesh where particles larger than barite are discarded and thrown away. In most drilling operations, a mud cleaner is installed in its mud systems. It is usually located in a mud tank in the same location as with the desilters.

The large cuttings in drilling fluids coming from the well are separated in the mud cleaner, and the treated mud enters next separation equipment for further processing. The performance and application of mud cleaner will exert direct influence on the effects of next separation equipment. The screen is designed on the basis of the vibration theory of the liner motion’s movement locus. The exciter moves the screen box back and forth so that the solid particles in the mud is sifted out from the surface to achieve the purpose of the solid and liquid separation.

Daily maintenance can ensure it has a longer service life and runs without trouble. The daily operation schedule is flexible. The users can change it according to their own application experience.

Mud Cleaner maintenance includes:

1. Vibration Motor Maintenance

(1) Clean dust on shell regularly

(2) Before operating, you must check the bolts to confirm whether it is loose or not. Otherwise, we must screw bolts tightly before running shaker.

(3) Inspect the cable, whether it is worn, held down, crushed, etc.

(4) The vibration motor should be well lubricated during operation.

Before fixing motors on shaker, the bearing is filled with SKF specific lubricating grease and the temperature is set -40~200℃.
 

2. Shaker Screen Maintenance

(1) Before every thing shuts off, the shaker should run without any load for 5-10 minutes, at the same time, use clean water to flush shaker screen clean.

(2) Every time it is shut down, the shaker frame and screen should be flushed by water. Please replace new screen or repair the damaged screen once it is found damaged, otherwise large cuttings may drop into the clean mud and influence the following processes.

3. Electric Cabinet Maintenance

4. Wear Parts Replacement

The user should check and replace the wear parts regularly. Apart from vibration motor, shaker screen and electric cabinet mentioned above, locking wedge, composite vibration spring as well as sealing rubber should be replaced at once.
