Hi Everyone,
We opted to re-fabricate this shaft as per the original design, with the holes in the shaft. Although it's still not exactly known why these holes were drilled in the shaft in the first place, we just thought we'd stick to the original design.
Thanks for your input.
This shaft sits at the bottom of a thickener tank, and moves the thick sledge along so that it doesn't stick to the bottom.
I don't think that the shaft would float in the tank since there is another pice at the bottom that keeps the shaft from deflecting.
This is a grandfathered design, so...
I recently had to replace an agitator shaft that was hollow. This shaft is essentially a SCH 80S 6" pipe, and rotates at a very low RPM (around 5 RPM). The shaft is about 8 ft tall.
The original design has two holes about 3/8" drilled into the shaft, one closer to the bottom, and one up top. I...
Thanks for the clarification Jono.
So is the main difference between case 1 and 2 is the amount of moment applied? how do I know when you use case 1, and case 2?
Hello,
I am wondering if any one can clarify Chart C-18 (page 358) in the MW Kellogg Design of Piping Systems book?
I don't understand the case scenarios and how the maximum moment and maximum deflection formulas are arrived at.
Especially the difference between case 1 and 2.. they have the...
