A Mud Agitator is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation.

The agitating shaft of mud agitator is the transmission structure can be rised. Agitator inadmissibility stopped in drilling process. It can’t get to the requirements in the practical work. After running of agitator, because sinking sand in the tank, maybe impellers buried in the sand, and it is difficult to start again. The impellers are often burned and appears motors burned. In order to solve the problem, usually oilfield adopts the agitator shaft which is can be rised, the impellers can be rised to a certain height. The impellers dive to the common location When re-start Agitator.


Agitator shaft of Mud agitator is divided into solid shaft and hollow shaft, the carbon steel shaft is the most commonly used. Solid shaft is directly on the reducer output shaft, usually adopts the rigid joint. There is a processed keyway on the bottom which can adjust the impellers installation height. It required inatall the stable end tube when the depth of container is exceed 1.83cm.

Hallow steel shaft apply to the deeper tank especially, they can connected with flange or bolt. Most hollow shaft all use bolt impellers which are joint to the scheduled location. Known from Mechanics of materials, in the same sectional area, hollow shaft more resistance to bend.

The rised agitating shaft is made of the hollow shaft of transmission torque and the screw shaft. The shaft installed agitating impellers connected the rised shaft through the coupling. The transmit torque can use the square hole, also can use the slide spline.

Mud agitator composed by explosion-proof motor, reducer, engine base and impeller components four parts .The motor and the speed reducer, reducer and the impeller shaft are connected through rigid coupling .

Agitating volume

According to production scale, agitating purpose and material performance to confirm the agitating shape and size. If don’t have special requirements, usually use upright cask container, meanwhile ensure the appropriate aspect ratio; if has the heat transfer requirements, the outside of kettle need set the jacketed structure.


Reduction gears

It should meet the requirements of power and rotary speed; operation is reliable, convenient to maintain; high mechanical efficiency and lower noise.


Agitating shaft has the enough spacing to ensure agitating shaft has little deflection amount; ensure the output shaft of transmission, agitating shaft and shaft sealing device is centring; have the enough radial and axial capability of adapting.

Shaft sealing

If allowed more fluid leakage, when the pressure in kettle is low can choose the packing seal; when allowed leakage, kettle pressure or vacuum is high, the friction energy consumption is less choose the mechanical sealing; when agitating medium is toxic or inflammable, explosive of expensive high purity material, or operate in high vacuum condition can choose the

Agitating shaft

Agitating shaft should have the enough torsional strength and bending strength. It must has the enough rigidity, rotary speed should avoid 800-1200r/min.


It should ensure material have the efficiency mix; consume the lowest power; needed the low cost; convenient to operate and maintain.
