    Hydraulic Circuit Design

    Hello Everyone,

    I need to design a hydraulic circuit to push 500 TON
    Force = mass x Acceleration = 4905 KN where Acceleration = G = 9.81

    then to get the Area of the Jack, I need to determine the working pressure to use it in P = F / A
    So my question is based on what shall I determine the pressure settings?

    After I get the area of the Jack, I can calculate the pump flow rate using Q = A x V where V= 3 to 4 cm/min

    Good I checked all the links but still can't understand what determine the pressure range for that application?

    You determine the pressure by comparing the capabilities of the cylinder and the pump. Select a pump you think will work. What pressure will that pump provide? Then select a cylinder that will handle that pressure and size the bore of the cylinder to create the desired force from that pressure.
