Deformation of the slurry tank mixer shaft
Thread Content
During operation, the agitator in the coal slurry tank is vertical with respect to the liquid level in the tank; theoretically, the forces acting on it should be uniform in all directions. Then why does bending occur? I hope all sea friends will leave active comments
It is likely that the load was too high, resulting in the shaft bending; this is for reference only.
The forces acting on a stationary mixer are uniform around it. Once the mixer starts to rotate, the action of liquids and slurries causes uneven forces to be applied around it; in such cases, the forces are calculated using a cantilever beam model, and torque also plays a role. For more details, one can refer to the book on chemical equipment design, specifically the chapter on mixers, which contains detailed calculation procedures
1. Hollow shaft; 2. Uneven material distribution and uneven stirring forces; 3. Not necessarily vertical
That is the condition under ideal circumstances; during actual operation, there are many complex factors at play.
I hope fellow enthusiasts can help me understand why, when it’s in operation, the forces applied are uneven around the edges; I’m not quite sure about this\ud83d\ude01\ud83d\ude01\ud83d\ude01
If the current changes, considering thickening the shaft diameter is an option. Change the angle of the impeller. It could be due to a low liquid level or idling
