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.
