Pneumatic cylinder Construction: Design
I don't have much knowledge in mechanical design or pneumatic systems.
For my project, I want to create a Pneumatic cylinder, The purpose is, Inside it will will contain a Nylon piston, and one end will be filled with clay. Cylinder will be closed from either side using end caps, which also has Push-in connectors(1/4" BSP). Compressed Air from a cylinder(Max. pressure of Cylinder 10 Bar) will be given to Piston side through a Non return valve and a Regulator. Which will push the Clay out through other end. It is for my Clay printer. Hope anyone here have some background with these kind of system
What should be the Wall thickness of Cylinder? It should safely handle Maximum pressure that might arise.
I have already provided a Safety valve calibrated at 6 Bar in my prototype that I made from a GI water Pipe, which has thickness of 3.85 mm. Is there any way the pressure inside the tank could reach a pressure higher than the maximum pressure Compressor can deliver (Compressor is rated for 10 Bar, with cutoff at 8 Bar)
I'm thinking about making the cylinder using a 100 x 5.75 mm Aluminium Pipe and End caps from Aluminum Rods with wall thickness of 10 mm. Would this be enough?
Should I give more thickness for End caps than cylinder?
How to find the maximum pressure rating of the cylinder if material, Wall thickness and diameter are known?
I asked this in another forum and one gay gave me two pictures
can anyone explain this to, what each parameter units are etc
Syringe pump use cheyyamallo?
Actually I want the capacity to be 3L or more. I already bought 100*6mm Aluminium pipe and 5" Aluminium Rod to make end caps??
Wet clay is thixotropic. The pressure needed to extrude will depend on the water content and the exit pipe diameter.
Are you trying to do some 3D printing?
I'm trying to 3d printing.
I already tested it in my prototype. It works. But I'm not sure that the cylinder is safe. I'm trying to make a new, that's why I asked about the pressure rating capacity, wall thickness etc
