[PSUBS-MAILIST] Fw: actuator

[Hugh Fulton via Personal_Submersibles]

Hi Hank,

Is the other end of the rod compensated?  i.e. if the rod is say ¾” diameter then 50 lbs is eaten up at 113 psi approx. 250 ft depth.  If it is 5/8” diam then you get to over 350 ft.  Actuators with the shaft out both ends are of course perfectly balanced.  Hugh

Hi All,

Here is a picture of my first electric liner actuator that is fully submersible.  The actuator can lift 50lbs  at 1 inch per second approximately.  The actuator cost me 50 dollars Canadian to make.  This one has a 4 inch stroke and is well suited for the second sage on the manipulator.    I can either air compensate  or oil compensate the actuator.  I can also put 160 psi inside permanently and use with no compensation to an undetermined depth.  

Hank
