Background technology
Pneumohydraulic pressure-cylinder is to be combined an oil hydraulic cylinder as integral type with booster, utilizes the compression of different sizes of booster
The ratio between area of section and Pascal's energy keep weighing apparatus principle and work.Because pressure is constant, when compression area from large to small when,
The principle that then pressure can also change with of different sizes, to reach the pressure result that atmospheric pressure is increased to decades of times, with
For prepressing type pressurized cylinder：When operating air pressure is pressed in hydraulic oil（Or piston）When surface, hydraulic oil meeting compressed air is acted on and is flowed
To precompressed stroke chamber, at this time hydraulic oil can rapid push type make displacement, the cylinder when work shift meets obstructions more than atmospheric pressure
Then stop acting, at this point, the booster cavity of pressurized cylinder is because of electric signal（Or pneumatic signal）Action starts supercharging to reach molding
The purpose of product.
The structure of hydraulic pressure booster cylinder includes oil hydraulic cylinder and booster, and booster includes oil storage cylinder and cylinder, and oil storage cylinder is gentle
Cylinder is connected by air compressor realizes that gas supply pushes, and makes piston rod output and retraction on oil hydraulic cylinder, since oil storage cylinder is in length
In phase compression transmit process, due to structure it is unreliable inevitably will appear loosening, cause gas leak of the oil leakage the phenomenon that, cause making for equipment
Use the lost of life.
