Hi - attached is 3 pages from the PARKER o ring guide and I am having trouble with specs in the military straight thread tube fitting chart not fitting the designated o-ring. I can't find a different resource for something in my thread size needed - 5/8-18
Does anyone have an alternative...
I build large ovens for powder coating. And exhaust vent location on ovens has always been an argued topic. Some people or companies use forced air propane/gas heaters, with fans that blow 30 CFM to 1450 CFM into almost air tight ovens. These ovens range in size from 4Lx4Wx8H' to 15Lx8Wx8H'...
Here it is specified that optimum operating temp for industrial C02 laser is within the range 59 °F to 77 °F. This is what is generally specified online, but it leads to a number of questions;
How is this measured? Does it refer to the whole unit, or the point of emission of the beam, or some...
This is a 3D model I made of a large industrial steam turbine.
It was modeled after one of the turbines at the Port Richmond generating station in Philadelphia Pennsylvania. I plan on modeling the entire turbine hall of that power plant, but that will take several months, at least. The program...
I have a source of electricity that's alternating but at variable frequencies. So an asynchronous alternating current of sorts if you will. Can industrial rechargeable batteries be charged like this efficiently? Or would DC current work best? Or normal AC?
Summary: Single shaft copper shredder
I design a rotor of a shredder, but i need to find a motor for the rotor of the shredder.
