Help: What should be done if the mixing tank shakes severely?
Thread Content
Dear seniors: There is currently a mixing tank with dimensions of ф2600*3500, a power rating of 15 Kw, and a rotation speed of 73 r/min. There is no vibration in the reducer and stirring shaft during operation, but the entire tank shakes severely and cannot be operated. I’m seeking help with a solution; I earnestly ask for your advice. Thank you!
Ensure the tank is properly secured; furthermore, your mixing is severely unbalanced and needs to be adjusted
The stirring isn’t at the center; the tank is under stress.
First, check the verticality of the shaft, its centering, as well as the imbalance of the blades (in terms of angle and weight). Address any issues that can be resolved; if not, then add a stabilizing ring under the mixing blades. The function of this stabilizing ring is to generate damping effect in order to reduce vibrations. For specific instructions, please refer to this forum: http://bbs.hcbbs.com/viewthread.php?tid=18321&highlight=%BD%C1%B0%E8%D3%EB%BB%EC%BA%CF%C9%E8%B1%B8%C9%E8%BC%C6%D1%A1%D3%C3%CA%D6%B2%E1
The stirring is off-center. First, adjust the stirring position and verticality ； Furthermore, the tank body support is reinforced.
1. Check whether the equipment foundation is secure; are the bolts tightened properly? 2. Are there any defects in the design of the equipment’s structure? A simple schematic diagram of the equipment installation can help identify these issues.
1 If there is a solid foundation, any shaking is simply due to issues with the bolts used for fixation; with foot bolts in place, the structure should not shake as a whole. Furthermore, is there a swirl plate inside this tank? At such high rotational speeds, if no swirl plate is used, the entire liquid will form a large vortex that drives the tank to move, making shaking inevitable. 2 If there is no foundation, it is recommended to check whether it is installed eccentrically. Moreover, the height-to-diameter ratio of this tank is not appropriate; a tank with a smaller height-to-diameter ratio should be built. This way, the above situation will be much better.
