[PSUBS-MAILIST] Manipulator arm

[swaters@waters-ks.com via Personal_Submersibles]

Gotcha. I got about 8 different suppliers I have found so far with SS cylinders. I think I'll order a few to play with. I am also planning on using electric silionoids for controlling the valves.
Thanks,
Scott Waters

Scott,
Gamma uses air cylinders with hydraulic fluid and pump.  The hydraulic system is very standard except it uses air cylinders in place of hydraulic cylinders.

Is Gamma all air cylinders? Do you just use
a air compressor? What happens to the air once it is in the
cylinder and you want to lower the cylinder? Is it
recompressed or somehow expelled? I really don't know
crap about pnematics. Haha. Why do all the subs use
hydrolics and not air. For example
hydro-lek?Thanks,Scott

Scott,
Not sure why you want hydraulic cylinders.  You want
air cylinders, they are light weight and all aluminum. 
If you use 2 in bore air cylinders you can run on a 500 psi
system.  Also air cylinders typically have 5/8 rods and
that is the most important part.  The rod size is what
the water pressure is pushing back against you system. 
Air cylinders have a single o ring on the piston and are
cheap and easy to replace. If you want ss rods then just
replace the chrome rods when they wear out.  I made my
own rods for Gamma, easy peezy.

  Are you using hydraulic cylinders or air cylinders.
