JULY Easy Disassembly 20 Ton Hydraulic Cylinder for Crane

The cylinder has a lightweight shape that is similar to the gas cylinder,and moves fast,has steady output speed, keeps stable in work status has short length in the longitudinal direction and so on. For its converse ,the shortcomings are that it has short stroke action and has certain restrictions on the installation and so on. Therefore this kind of cylinder applies to the workplace that prepress length is not very long. As a result of the above characteristics, it applies to product forming,plastic welding,riveting electronic components,forming metal sheet and so on.

Hydro pneumatic cylinder is combined the oil pressure cylinder and booster together for taking pure gas press as the power source. It makes use of the different size of booster, the crosssection area compression ratio and Pascal energy conservation principle. Because of constant pressure, when the compression area change from small to large, the press would vary with the size, so as to raise the gas pressure to tens. Taking the prepress standard hydro pneumatic cylinder as an example: When the work gas pressed on the hydraulic oil (or working piston) surface, hydraulic oil would flow to the approach stroke cavity because of the air pressure, then the hydraulic oil would promote the workpiece to move rapidly. When the workpiece is meet the resistance larger than the gas pressure, it stops moving. At this point, the booster cavity start moving because of the signal (or pneumatic signal), then achieve the purpose of moding products!

Fast speed: The action speed is faster than the hydraulic drive and it is more stability than pneumatic drive;

Easy to use: The cylinder body device is simple, so it is easy to adjust the output and facilitate to use and maintain;

High output: It can reach the highest output of oil hydraulic machine under same conditions, which can not be achieved by the pure pneumatic machine;

Low price: The price is lower than the oil pressure system;

Easy to maintain: The simple structure is easier to maintain than the oil pressure system;

Low energy consumption: When continue to boost or stop moving, it does not need the motor to keep working as the hydraulic system, then the energy can be saved. And it is convenient to take the power source, so the actual energy consumption is equivalent to 10%-30% of hydraulic power system;

No leakage: Energy conversion is easy with zero leakage, so not worry about the environmental pollution;

No harm to the die: In order to meet the technology needs, stamping pressure and the work stroke can keep within the provided area without adjustable levels;

Easy installation: There are several ways to in stall according to different work environments at any angle and position;

Soft landing: Soft-stamping technology reduce the noise to protect the die;

Fault less: No temperature rising problems unlike the hydraulic system;

Small space: Space area can be less than 50% compare with normal air cylinder and hydraulic station;

Less fault : No temperature rising problems unlike the hydraulic system;
