The pressurized cylinder is a hydraulic element that can change the input pressure to output at a higher pressure. Booster cylinder is a hydraulic cylinder and the supercharger for one-piece combination, use different compression ratio of the cross section area of the size of the supercharger, because pressure is constant, when the pressure change from big to small, the pressure will change with different sizes and principle, so as to achieve to increase the air pressure to dozens of times the pressure effect, preloading type pressurized cylinder, for example:When work pressure in the hydraulic oil (or piston) surface, the hydraulic oil will be compressed air cavity and flow to the preloading trip, the hydraulic oil will quickly push for displacement, displacement resistance is greater than atmospheric pressure when the work pressure cylinder is to stop the action, at this point, the booster cylinder pressure cavity because electrical signals (or pneumatic) action, start charging so as to achieve the aim of molding products.Supercharging cylinders can be generally divided into: pre-pressure supercharging cylinder, direct pressure supercharging cylinder, stroke gas-liquid supercharging cylinder, increased return tension supercharging cylinder, compact parallel supercharging cylinder, mini supercharging cylinder, fast supercharging cylinder, and oil-gas isolation supercharging cylinder.The working frequency of the pressurized cylinder is generally 10~70 times/min according to different stroke and cylinder diameter Actuating mode: double actuating. Operation speed: 50~1000mm/s. Output range: 1~100 tons. Application: imprint marks, bending profiles, die punching, punching steel, profile welding, extrusion molding, pressing and straightening, riveting forging, integral sheet metal, tight assembly, riveting connection, metal stamping. • Cylinder diameter: 40. 60 • Easy to achieve high output power • Direct pressure type and pre-pressure type are available
