Gas-liquid booster cylinder
AT series split -type working cylinder
Working pressure: ≤6bar

Pressure: 2-2000 kN

Power stroke: 5-52mm

Total stroke: 100/200/250mm

Pneumatic-hydraulic drive combines the advantages of compressed air and hydraulic systems, combining the high-speed movement of independent cylinders with the high strength of the hydraulic system to achieve pneumatic rapid forward and pneumatic rapid retreat, and uses a supercharger to provide high-pressure oil to complete the work. Its control logic is consistent with the standard gas-liquid cylinder.

Cylinder Selection Example

Requirements: 2 cylinders, thrust 60kN, stroke 130mm, pressure stroke 12mm, side outlet, synchronous action, hydraulic hose length 1200mm, booster optional.

The AT08 type cylinder outputs 81 kN of torque at a maximum hydraulic pressure of 400 bar, meeting the 60 kN requirement. The matching booster must be from the MPS series, which converts 6 bar of air pressure into a maximum hydraulic output of 400 bar.

A1 (Cylinder Stroke): Since the required stroke is 130 mm, a standard 150 mm stroke is selected.

Total volume of dual cylinders = 2 × 150 × 1.96 cubic centimeters (V) × 1.5 (safety air storage factor) = 882 cubic centimeters

A2 (volume loss due to hose length) = (1200/50) × 3.5 ml (V1) = 84 ml

A0 (total low-pressure oil requirement): 882 cc + 84 cc = 966 cc.

B1 (cylinder consumption): Volume of 2 cylinders = 2 × 12 × 1.96 cc (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 high-pressure oil required): 47.04 cc + 21.6 cc = 68.64 cc.

Final Selection Results:

Working Cylinder: AT08-150-02 (Quantity: 2 units)

Drive Supercharger: MPS160.60.100 (Quantity: 1 unit)

High-Pressure Hoses: VH04-1200 (Quantity: 2 pieces)
