I know how to calcaulate the required torque. My question is, what friction coefficient should I use? The screw is steel and the nut is bronze. <p>Bob Kennedy<br><a href=mailto:BobK@tdsdesign.com>BobK@tdsdesign.com</a><br><a href=http://www.tdsdesign.com>Turnkey Design...
Does anybody have any friction data for acme screw threads? I have a 1/4-16 double lead screw thread and want to compute the torque required to move the screw.
This is a very low flow rate (.002 gpm). Your leakage at 500 psi will be higher than your delivered flow. Is leakage a concern? <br>Your best bet is a gear or a swash-plate piston pump. Do have any other options besides 316SS for the pumping elements? I would not...
We are designing a rotary vane pump that will be pumping pure oxygen. There is a concern about using carbon based materials from an ignition standpoint. With that in mind we are looking to use non-metallic vanes. The vane material is Torlon 4301 which is...
