Working principle and characteristics of mud agitator

The mud agitator is a continuous and reliable drilling mud solids control system for the drilling fluid to maintain the uniformity of the drilling fluid and suspend the solid particles. It is mainly used for the stirring and mixing of drilling fluid to prevent the solid particles of the drilling fluid from depositing in the tank circulation system, so that the performance of the circulating drilling fluid is stable and the mixing is uniform. The mud agitator is mainly composed of explosion-proof motor, reducer, base and pulsator components. The motor and reducer, and the reducer and pulsator shaft are all connected by a rigid coupling. The pulsator is assembled by welding 4 blades.

The mud agitator is suitable for mixing petroleum drilling fluid. The mud agitator below 5.5kW adopts a cycloid reducer, and the mud agitator of drilling fluid above 7.5kW adopts a turbo-worm type reduction transmission. The pulsator can make the mixing liquid produce vortex motion, thereby enhancing the mixing effect. The tray sandwiched between the blades can also prevent the solid particles of the mud from depositing around the lower blades after shutdown. This use can reduce the drag torque of the sediment on the blades during startup, thereby avoiding overloading and burning of the motor.

The mud agitator has the advantages of compact structure, small footprint, large transmission torque, stable operation and reliable operation.

1. The arc cylindrical worm reducer is adopted, the shaft section is a circular cylindrical worm, and the tooth profile of the worm gear is a circle that is conjugated to the worm. Therefore, the convex-concave meshing performance is reliable, the benefit is high, and the structure is compact.

2. Combination of reducer and explosion-proof motor is convenient for maintenance and suitable for use under harsh working conditions in the field.

3. The stirring intensity is large, the spreading range is wide, and the starting resistance torque is reduced.

4. The motor is placed horizontally, which is convenient for installation, adjustment and replacement.

5. Various gearbox and blade combinations can meet most requirements;

6. The mud agitator has high efficiency in deep and large containers;

7. It can be designed to produce suitable shear force according to needs;

8. Expose more fluid to contact with the atmosphere, and the mud agitator helps cool the drilling fluid.
