The gas-hydraulic pressurized cylinder is an energy-saving and environmentally friendly product that replaces the traditional cylinder, hydraulic cylinder and other equipment, which many people should already know. For the types of such products, may not be very clear, the following for you to answer one by one. I hope it will be helpful to you in product understanding and selection.

Working principle of gas-liquid booster cylinder

The gas-hydraulic booster cylinder is a combination of an oil cylinder and a booster. The pure air pressure is used as the power source, and the ratio of the cross-sectional area of the supercharger and the PASCAL principle of energy conservation are used. The low pressure of the air pressure is increased by dozens of times to supply the hydraulic cylinder for use, so as to achieve the purpose of product molding. Because the pressure is unchanged, when the pressure area is changed from large to small, the pressure will also change with the size of the principle, so as to achieve the pressure of the air pressure to dozens of times the pressure effect. Take the pre-pressurized gas-hydraulic booster cylinder as an example: When the working pressure is pressed on the surface of the hydraulic oil (or piston), the hydraulic oil will compress the air and flow to the pre-pressure stroke chamber, at this time the hydraulic oil will quickly push the type to displacement, when the working displacement encountered resistance greater than the pressure cylinder will stop the action, at this time, the pressure chamber of the gas-liquid pressurization cylinder because of the electrical signal (or pneumatic signal) action, began to pressurize to achieve the purpose of forming the product.

Type of gas-liquid pressurization cylinder

In general, it is mainly divided into two categories, respectively, direct pressure type and pre-pressure type booster cylinder. The direct pressure type has only one stroke (booster output stroke), and the prepressure type has two strokes (prepressure stroke + booster stroke).

Gas-hydraulic cylinder type subdivision: although it is generally a direct pressure type and a pre-pressure type of products, there are more than ten types of conventional models and non-standard customization. Conventional booster cylinder model types are standard booster cylinder, stroke adjustable booster cylinder (total stroke adjustable, force stroke adjustable, total stroke and force stroke adjustable and magnetic adjustable), direct pressure type, mini, fast type, oil and gas isolation type, integrated, compact, parallel and so on.

According to the installation method can also be divided into formal type, horizontal installation type, flip type, arbitrary Angle installation type and so on.

How to select columns between molds when assisting mold design? Check the number and placement of cavities. Because the number and placement have a great impact on the system oil circuit balance of the high-temperature ultra-high pressure microcylinders between the molds. Select an even number of cavities arranged symmetrically. Since the CAL module is in the hollow and there is the core of the micro ultra-high pressure cylinder mold, the hollow plate is too thin and cannot reach the desired state, and the blade module makes the cylinder too thin and increases the weight of the mold, and the mold is urgently needed before importing the system, so it is easy to determine the thickness of the core and template with the manufacturer. Restriction on the number of holes. Hot parts limit the distance of small cavities, so be careful to check part distances when designing cavities very close together.
