Whether the tank is stirred clockwise or counterclockwise depends on the design. If the design has no turn mark, it can turn left or right. The steering of the reducer is generally ok. The direction of the agitator depends on the type of the agitator blade and should be given in the design direction (clockwise or counterclockwise).

The direction of agitator can not be arbitrarily changed, because on some occasions the impeller is locked by the lock nut on the mixing shaft, and generally the direction of the direction of the thread is opposite. The steering of the output shaft of the reducer should be the same as that of the agitator, so that the steering of the input shaft and the motor can be determined. The speed reducer of the stirring motor has the direction of stirring rotation. According to the provisions of the speed reducer, the process design should also meet the requirements of the equipment. Once the agitator of the tank is selected, its steering is determined and cannot be arbitrarily changed.

Stirring vessel standard is, generally in the drawings should indicate the rotation of the stirring shaft, if it is really necessary to reverse, it must be indicated in the technical requirements, and the specified speed. However, this is not done in the actual process, so it is indicated in the drawing (normal operation), such as positive rotation indicated in the drawing, but there may be instantaneous or intermittent reversal (abnormal operation) in the actual process, generally the speed of reversal is relatively slow and the time is relatively short, so it is not considered. And you need to calculate the strength of the spoiler. There are also many problems encountered in the actual process. When the motor or process absolutely does not support reversal, it will be indicated in the technical requirements that "the rotation direction of the stirring shaft should be consistent with the picture, and no reversal".
