The shape, size, and deformation of the agitator. The shape and size of the reactor. The liquid movement in the reactor. Among them, the eddy current generated by the relative motion between the agitator blade and the medium causes the vibration of the agitator.
The analysis shows that the main reason for the strong vibration of the agitator is that the actual working speed is close to the critical speed. Due to the limitation of process conditions, it is difficult to change the actual speed of the agitator mixer. So the measure of installing a damping block on the mixing shaft is taken.
