In Reply to: IS ANYONE USING PNUEMATICS
Posted by Rimple Bhakta on 2/5/2001 3:48 PM EST:
We are using pneumatics to help lower the bridge and stow the front grabber in the robot (to save space). However, we are having problems keeping in air. Our pressure drops about 1 psi/sec. We did wrap all of the pipes in teflon (before that, we couldn't get more than 20 psi). Hence, we might leave the pump always on. It only drains 2-3 amps, right? If I feel the need, I'll make a half decent routine in the program to turn the pump off but I'm afraid of the pump constantly turning on and off.
We are using the pump -> one tank (-> pressure "limit switch"

-> SMC pressure regulator -> "union T" -> solenoids. Are we something wrong? Any ideas? Thanks
