[Help] Ultra-long mixing shaft for extra-high equipment... a 30-meter mixing shaft.
Thread Content
The customer provided a device that is nearly 40 meters long, and a mixing shaft of about 30 meters length is required for continuous mixing. The calculated power is 60 kilowatts. Then, it’s over. Calculate the shaft diameter: 750……Oh my God. Single-span calculation is still used. Is the diameter of such an ultra-long axis really that thick? Can another middle bearing be installed? How do I calculate it? I flipped through the book, but there was no relevant information. I’d appreciate some advice from the experts here.
Intermediate bearings and bottom bearings should be added
What formula is used to calculate the diameter of the stirring shaft? Are there any relevant standard books?
You can consult the design institute of CSSC.
End supports and intermediate supports (more than one) must be added
What kind of process is it? Can’t it be divided into smaller reactors with smaller agitators? Is it operated from an airplane? Why not choose bottom stirring?
If bottom stirring is to be achieved by using openings at the bottom, the key issue is the dynamic seal, which should not pose a problem.
It’s best to use the bottom of the tank for stirring this stuff.
I’ve seen many bottom stirring setups, and they’re not any kind of challenge
Bottom stirring is the most suitable option; sealing technology is now very advanced. Don’t worry
