    Determine cylinders for my system.

    Hi again! I have made another adjustment. I did place an third cylinder that should act like a lock for the door that going to be opened. So when the door is down it will be locked with the third cylinder. Then i want the two opening cylinders to NOT begin operating before the third cylinder is...

    Determine cylinders for my system.

    Hi Ted! I made a small adjustment to go with the relief valves you were suggested. Is this a more correctly drawn system? Would this work? Thanks again for your valuable inputs!

    Hi Ted Thank you again for your effort to help me, i appreciate it! Like i did in the picture at the left(pilot operated check valve)? Oh, so should switch the directional control valve (with the bypass position) to same valve but with float position? And keep the unloader valve at the left...

    Determine cylinders for my system.

    Thank you, really appreciate the feedback! One question, the cylinders do they need to be double-acting? Since the hatch itself should have enough weight to pull the cylinders back into place? -if i use an single-acting cylinder, do i need to compensate with some kind of damping effect so the...

    Thank you for your answer!. Yeah i think i was aiming for an to big bore size. I would like to have the hatch open alot faster aswell. I am still somewhat uncertain on how the acctually schemeatic would look on paper. I tried to draw it in fluidsimulation, with some adjustment that Ted talked...

    Determine cylinders for my system.

    Hi Ted and thank you for your reply, i really appreciate it! # The check valves at the cylinders were my try to stop the hatch from going down again in case of leakage in the direction valve. # Regarding the filter i just did not think it did matter if i had it as a suction filter or as a...

    Determine cylinders for my system.

    Hi! I have constructed a simple hydralic system (on paper) that should be able to open a cargo door. As you can see it will have 2 lifting cylinders. To open the cargo door a force of 45kN is required for each cylinder. The stroke has to me 600mm. The pump that will be used: Deplacement ...
