Pneumohydraulic Drive with Separate Working Cylinder | AT Series

Pneumohydraulic Drive (with Separate Working Cylinder), AT Series

Operating pressure ≤6bar
Pressing force 2-2000kN
Force stroke 5-52mm
Total stroke 100/200/250mm

The pneumohydraulic drive combines the advantages of compressed air and hydraulic systems, integrating the high-speed motion of the separate pneumatic cylinder with the high intensity of hydraulic systems. It enables pneumatic rapid advance, pneumatic rapid return, and utilizes the intensifier to provide high-pressure oil to achieve work. The control logic is consistent with standard pneumohydraulic cylinders.

Cylinder Selection Example

Requirement: 2 cylinders with 60kN force, 130mm stroke, 12mm pressure stroke, side-exit oil port, synchronous action, oil pipe length 1200mm, with an intensifier option.
The AT08 cylinder outputs 81 kN at a maximum oil pressure of 400 bar, which meets the 60kN requirement. The corresponding intensifier must be the MPS series, which converts 6 bar air pressure into a maximum 400 bar hydraulic output.
A1 (Cylinder Stroke): Since the required stroke is 130mm, a standard 150mm stroke is selected.
Total volume for 2 cylinders = 2×150 ×1.96CC (V)×1.5 (Safety storage coefficient) = 882CC
A2 (Volume Loss Due to Hose Length) = (1200/50)×3.5CC (V1) = 84CC
A0 (Total Required Low-Pressure Oil): 882CC + 84CC = 966CC.
B1 (Cylinder Consumption): Volume for 2 cylinders = 2×12×1.96CC (V) = 47.04 CC.
B2 (Volume Loss Due to High-Pressure Hose Expansion) = 2×(1200/100)×0.9 CC (V2) = 21.6 CC.
B0 (Total Required High-Pressure Oil): 47.04 CC + 21.6 CC = 68.64 CC.
