A differential cylinder with the area ratio p of 2.5:1 is to lift 50 kN 500 mm in 4 secs. The maximum system pressure for the pump is to be 160 bar. Calculate the piston diameter and find the piston rod diameter dst. On the basis of the piston rod diameter dst, find the maximum possible stroke. (length) from the buckling resistance diagram. In addition, calculate the advance and return speeds for the piston and the pump delivery. The mechanical, hydraulic efficiency of the cylinder amounts to n= 0.90. Pipe loss amounts to 6 bar, pressure drop in the directional control valve 2 bar and back pressure from the return movement 2 bar.
