water hydraulic system

[AngeloB]

Hello everyone
I was looking for information on the acup site and I realized that they have a series of cylinders designed to work with water instead of oil.
I did not know that there were cylinders of this type, in some cases being able to use water would solve many problems.
How do these plants behave? I can understand that a stainless steel cylinder can work well with water, but are they suitable solenoid valves? What kind of pumps should you use? Do I have to change the hoses?
I asked my colleagues but no one knows anything about it, now I'll ask myself to the agop.
do you have experiences about it?

I think it's about water-glycol. is not water "of tap", but water with added additives. behaves like oil, but has better resistance to fire.
identical components to use with oil.
behave slightly differently, especially if you have strange components, such as proportional valves, flow regulators and other fines. .

confirmation mbt
hydrodynamic plants using water as is if they see very few and almost always in low critical conditions, type pressures not too high, fixed flow and with on-off drives, therefore without any proportional regulation.
and also in these conditions the maintenance intervals are about 1/4 of those operated with water-glycol and from 1/6 to 1/10 of those with oil.

not to mention the costs, not only the stainless steel cylinders and related seals, or the basic manifolds/platches that can be in aluminium, but also and especially for the directional and control valves, in which there are big problems of wear and risk of blocking for too much similarity of the materials used for bodies, drawers and shutters.

there are some houses that have attempted hybrid solutions, of the body type in steel or cast iron chemically nickeled, with stainless coats reported, but in the end, for the series "dallo and from the if it goes too 'or metal", the corrosion makes itself the same way, and then it throws all in scrap.

Hi.
water plants exist ..... water cylinders there are (in some cases they are built to measure and specially for the plant ), there are water valves for the management control both on/off and proportional (with piloting or oil or water ) working pressures can reach 300 bar
pumps used are water piston pumps (there are different brands) if you want a proportional control you can handle them with inverters
However if you want more clarifications look your info

I hope you've solved it in the meantime, since it's been almost 10 years....

I'm sorry but I registered now and I didn't see the date... only that came out this signal as before ....
Okay.

Anyway, it might interest me, do you have references?
Thank you.
