Hight Pressure Hydraulic Cylinder (Pressing Cylinder) 75x70x300mm · 模型 309956
· High Pressure Hydraulic Cylinder: · This indicates the cylinder is designed to operate at pressures significantly higher than standard industrial hydraulics (typically above 210 bar / 3000 PSI). It may be rated for 350 bar (5000 PSI) or even 700 bar (10,000 PSI) depending on the application . · Design Features: Thicker barrel walls, high-strength materials, special high-pressure seals, and robust end cap retention mechanisms to safely contain the extreme forces. · Pressing Cylinder: · This specifies the application. Pressing cylinders are used in hydraulic presses for stamping, forming, molding, forging, and assembly operations . · Key Requirements: High force, rigidity, minimal deflection under load, and often precise control over pressing speed and force. They must withstand millions of cycles over their lifetime. · Dimensions (75x70x300): · 75 mm: The Bore Diameter. The internal diameter of the cylinder barrel. · 70 mm: The Rod Diameter. The thickness of the piston rod. This is an extremely unusual and heavy-duty ratio. The rod is 70mm, which is 93% of the 75mm bore diameter. · 300 mm: The Stroke Length. 2. Technical Characteristics · Extreme Rod-to-Bore Ratio: · The 70mm rod on a 75mm bore is a ultra-heavy-duty rod ratio (approx. 93%) . This is not a standard cylinder; it is a custom or specialized design for applications requiring maximum rigidity. · Implications: · Very High Column Strength: The rod is exceptionally resistant to buckling under compressive loads. · High Side Load Capacity: Can withstand significant off-center forces without bending. · Reduced Annulus Area: The area on the retract side (bore area minus rod area) is very small. This means the retract force will be significantly lower than the extend force, and retraction speed will be much faster for the same flow rate. · Force Generation (High Pressure Capability): · This cylinder is likely rated for high pressure to achieve significant force despite the relatively modest bore size. · Example Calculation at 350 bar (approx. 5000 PSI): · Piston Area = π × (3.75 cm)² ≈ 44.2 cm² · Push Force ≈ 44.2 cm² × 350 kg/cm² = 15,470 kg (approx. 15.5 Tons or 34,100 lbs). · Example Calculation at 700 bar (approx. 10,000 PSI): · Push Force ≈ 44.2 cm² × 700 kg/cm² = 30,940 kg (approx. 31 Tons or 68,200 lbs). · Retract Force Calculation (at 350 bar): · Annulus Area = Piston Area - Rod Area = 44.2 cm² - (π × (3.5 cm)² ≈ 38.5 cm²) = 5.7 cm²
