ULCH Horizontal Hydro-pneumatic cylinder Product Principle
Hydro pneumatic cylinder is combined the oil pressure cylinder and booster together for taking pure gas
press as thepower source.
It makes use of the different size of booster, the crosssection area compression ratio and Pascal energy
conservation principle. Becaus 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 theworkpiece 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!

Main Technical Drawing of ULCH Horizontal type hydro pneumatic cylinder
Advantages of the air oil pressure 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 air liquid pressurized 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 ULCA-80-100-10E-5T), the hydro-pneumatic cylinder consumes 2575cm³ air while the pneumatic cylinder
is 15790cm³,refers to the drawing:
