[PSUBS-MAILIST] Manipulator

Scott,
All oils used on the water should be environmentally friendly.  I use vegetable oil in my launch cart.

 Alan, I
 looked into air, but it presents some problems. One is
 compensating it otherwise you will get less preformance
 based on depth. Two is they are not as stiff and have give
 as well as less fine control. Also another problem is if you
 used compressed air, you have a limiting factor or you could
 use a compressor, but have to have a bank to draw
 from.The main draw back of hydraulic for me was
 the mess and polution factor. Otherwise, hydraulic seems to
 be the way to go.I am hoping to come up with a
 manipulator design that can be used on most psubs that is
 easy and affordable.Thanks,Scott

 Hank,why not
 just use air if the pneumatic cylinders are rated for 150
 psi.If they
 are rated for 150 psi it would be assumed that their
 mechanical strengthwould
 match the load they can lift with 150 psi
 also.Is there
 any advantage other than the o ring working both ways to
 stop wateringress,
 as you have said previously. Does anyone else use them in
 placeof
 hydraulic cylinders?Alan

 No problems, Gamma has air
 cylinders and at 1,000 feet the hydraulic pump is set at
 1,100 psi.  Your K sub can have a pressure setting of 500
 or less and work just fine. Remember, your not lifting a lot
 just the arm plus a bit.

  Do you
  have any problem with over pressure though?
 The pnuematic
  cylinders are rated to 150psi
 with air and 1000 psi with
 
 oil. Thanks,Scott

  hi Scott
  use a
  hydraulic pump just the
 same as if you used hydraulic
  cylinders

          Hank,I know you
  said to use
 pnumatic cylinders  for the manipulator arm.
  What kind of pump do you
 
 use?Thanks,Scott Waters
