Pressure cylinder is a hydraulic cylinder and the supercharger for one-piece, combining with the size of the supercharger different compression ratio of the cross section area, 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 pressure cylinder, for example: When work pressure in the surface of the hydraulic oil, 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 pressure cylinder pressure cavity because pneumatic letter) action, start charging so as to achieve the aim of molding products.

Working principle of gas-liquid supercharging cylinder

Gas-liquid boosting cylinder is combined with the cylinder and the cylinder advantages and design improvements, the hydraulic oil and strict isolation, compressed air in cylinder piston rod contact work piece automatically after the trip, movement speed, stability, and a pneumatic transmission block device is simple, the output adjustment easy, the same conditions can achieve higher force of hydraulic press, low loss, easy installation, small occupied space, Less trouble without temperature rise, long life, low noise, and other core characteristics.

1. Pre-pressurized cylinder: When the working pressure is on the surface of the hydraulic oil, the hydraulic oil will flow to the preloading stroke chamber due to the action of compressed air. At this time, the hydraulic oil will quickly push the shaft for displacement. When the resistance encountered by the working displacement is greater than the pressure pressure, the preloading shaft will stop action. The pressurizing shaft also begins to move and squeezes the low-pressure oil in the pre-pressurized cylinder block to pressurize it to produce a powerful thrust effect.

2. Straight pressurizing cylinder: when the working pressure is on the piston surface of the pressurizing section, the piston will flow to the oil chamber due to the action of compressed air. At this time, the hydraulic oil will quickly push the axis for displacement, and the distance (stroke) of the axis will be high pressure stroke (pressurizing stroke).
