the customer told me they were running at 3200 psi, note we repair and reseal the cylinders but seems like we are always responsible for customers systems lol. we will get it fix. my goal is to give insight of the hydraulic business and how it works.....
idk if you guys have a tool to make a 3d scan of the object, you could see where the liquid can come out, but i know these metals are dense for xrays. i'm not a specialist so don't take my words for advice, im just a guy on youtube who think it is intersting and want to learn more
When the cylinder is run all the way out, it is the same as putting a load on it. Pressure against the stop would be the same as pressure against a load. And if he wanted, he could run a length of chain around the entire cylinder and press against that which would simulate a load at any length of piston travel.
how would you do it to be cost effective the load is thousands of pounds, all we could do is a simulation, we have done 100s of thousands of cylinder repairs
Let the cylinder sit full of oil at zero pressure for a half hour. Sometimes the leak is at low pressure when the machine is sitting. If it leaks then you probably have some damage in your seal groove. It could be a deep scratch or pitting from corrosion, it could also be that the seal groove is out of round which would be hard to determine unless you set the gland up in a lathe. I usually skim .005-.010 out of the seal groove if you have any of the above issues and problem is cured.
Pressure relief valve could be set to high or cheap oil

would not be cost effective for us as small business
@@LOWBROW369 if you guys need softwares to be written for some hardware, hit me up
Pity you cant put a load on it

@@HueToobBlows It could be leaking anywhere along the stroke, and without a load it would never show.
@@lastmanstanding9389 You saw the part of my post where i mentioned "chain" and "points along stroke" didn't you?
Test it under load?

@@LOWBROW369 I am sure you could rig together a universal fit kind of a thing for less than $1000
@@mechcntr7185 i wouldn't put my hand on that machine lol

this cylinder works with another one 22 hrs a day hard, customer just authorized us to machine a new rod
Too low of viscosity in customers equipment?
could be system runs 22 hrs a day oil is hot as hell its just the way it is high pressures also
