Performace

The merits of the cylinder include fast action (faster than the standard cylinder for 50 - 100%), low-cost of after-sale maintenance and using (it is necessary to replenish after the hydraulic oil is consumed,it can be replenished by the special supplementary cup automatically ). For the shortcomings, the installation and the longitudinal length are difficult to control, so the cylinder is only installed upright (that is from top to down), the up-side down or casual angle installation are not allowed. And it is little long in the longitudinal length, so it only applies to the work situation without restrictions in longitudinal length, as a result of the above characteristics, this cylinder applies to products forming, bearing and other hardware's assembly, squeezing die and forming, as well as other fast frequency work situations. 

 


Product Principle

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!

 


Advantages of the hydropneumatic cylinder

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;

 

The energy loss comparison chart of hydropneumatic cylinder and pneumatic cylinder

The ratio of air consumption takes hydropneumatic cylinder and pneumatic cylinder with the same output as the example: When the working air pressure is 6kg/cm² and the diameter is 320mm, the pneumatic cylinder reaches 4800kg, but the output of hydropneumatic cylinder is 4800kg and the diameter is 80mm. When the stroke is the same 100mm(the model of pneumatic cylinder is QGB 320*100 and the hydropneumatic cylinder is JLC-80-100-10E-5T), the hydro-pneumatic cylinder consumes 2575cm³ air while the pneumatic cylinder is 15790cm³,refers to the drawing:
