Hydraulic system booster cylinder introduction

The booster cylinder is improved by combining the advantages of the cylinder and the cylinder. The hydraulic oil and compressed air are strictly isolated, the piston rod in the cylinder starts automatically after contacting the working part, the action speed is fast, and it is more stable than the pneumatic transmission, the cylinder block device is simple, the output adjustment is easy, the high force of the hydraulic press can be achieved under the same conditions, the energy consumption is low, and the soft landing does not damage the mold. Easy to install and special booster cylinder can be installed at any Angle of 360 degrees, occupy a small space, less trouble without temperature rise, long life, low noise, and other core characteristics.

1 Supercharging cylinder principle

The booster cylinder is a hydraulic component that can change the input pressure and output it at a higher pressure. The booster cylinder is a combination of a hydraulic cylinder and a supercharger, using the ratio of the size of the supercharger to the area of the compression section, and the PASCAL energy principle to work. 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 pressure increased to dozens of times the pressure effect, taking the pre-pressure 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 pressurizing chamber of the pressurizing cylinder because of the electrical signal (or pneumatic signal) action, began to pressurize to achieve the purpose of forming the product.

2 booster cylinder features

Fast speed
The action speed is faster than hydraulic transmission, and more stable than pneumatic transmission;

Easy to use
The cylinder body is simple, the output adjustment is easy, the use and maintenance are convenient;

Great contribution
Under the same conditions, the high force of the hydraulic press can be reached, and the non-pure pressure system can be reached.

Low price
The unit price of equipment is lower than that of oil pressure system;

Easy to maintain
Because of the simple structure, it is easier to maintain than the oil pressure system;

Low energy consumption
When continuous pressure or stop action, do not have to be like a pure hydraulic system, the motor needs to continue to run, so it can save energy, and the power source is convenient and easy to access, the actual energy consumption is equivalent to 10%-30% of the oil pressure system;

non-disclosure
Energy conversion is convenient, and zero internal leakage can be achieved without worrying about environmental pollution;

Mold free
In order to meet the needs of the process, the impact pressure and working stroke can be stepless adjustable within the specified range.

Easy to install
There are a variety of installation methods, according to different work occasions can be installed at any Angle and position;

Soft landing
Soft stamping technology, so that the operating noise is small and protect your mold;

Less trouble
No oil pressure system temperature rise trouble;

Small space
Compared with ordinary cylinders and hydraulic stations, the occupied space area can be less than 50%

3 Precautions

Since the pressurized cylinder is often in a state of high-speed operation, it is easy to cause machine wear, so it should be operated according to the operating instructions, the working temperature of the pressurized cylinder is about -5 ° C ~60 ° C, and the operating speed is 50~1000mm/s, in order to ensure the normal work of the pressurized cylinder, the following points should be paid attention to in use:

Keep clean

Before connecting the booster cylinder to the gas circuit, please remove dust and other debris in the pipeline and components first, so as not to reduce the service life of the booster cylinder.

Use within normal air pressure range

The working pressure of the cylinder in normal use must be in accordance with the working pressure range specified in the inspection report, and shall not exceed the specified working pressure.

Pay attention to the working environment of the booster cylinder

The temperature in the working environment of the cylinder at the time of design has been set. If the working environment exceeds the temperature due to work needs, contact the relevant personnel of the pressurized cylinder technology.

Because some of the components in the cylinder are iron, please do not use it in a particularly complex working environment (such as chemical contact environment), and please install an effective air handling element (three-point combination) at the front of the cylinder and lubricate and drain when connected.

Do not change other hydraulic oil

The hydraulic oil medium selected in the design of the booster cylinder is VG68# anti-wear hydraulic oil, and other liquid media (such as oil) cannot be changed without authorization. Water, etc.)

Make sure you follow the procedure

The action procedure must be in accordance with the action procedure of the gas circuit assembly diagram, that is, the pre-pressure action - the boost action - the boost release pressure - the pre-pressure reset

Pay attention to maintenance, often check the operation of the booster cylinder

In order to avoid the excessive pressure of the cylinder during pressurization to damage your mold or workpiece, please install a pressure reducing valve at the inlet of the pressurization section of the pressurization cylinder to effectively protect your product.

In order to ensure the working stability of the booster cylinder, it is recommended to install an air storage cylinder in parallel between the three couplings and the booster cylinder as far as possible.

When the pressurized cylinder is used more than 50,000 times or more than half a year, it is recommended to replace all the hydraulic oil in the cylinder once to improve the service life and working life of the cylinder.
