[0002]
Bottled high-pressure cold air is often used in many hydraulic systems, and the pressure is generally above 16MPa. In many cases, after the high-pressure cold air cylinder is used, the remaining pressure does not meet the pressure requirements for continued use, but it is still relatively high. For example, some hydraulic In the device fatigue test, it cannot be used if it is lower than 10MPa
It would be a waste to let go of this and buy a full pressure cylinder
Especially in some places where the pressure consumption of high-pressure gas cylinders is fast and the usage is large, but the minimum operating pressure is high, the remaining pressure in many gas cylinders is all wasted
Equipping high-pressure air source is currently the solution to general high-pressure air-conditioning. For hydraulic systems that only use high-pressure air-conditioning frequently for a period of time, it is a waste of resources. Existing hydraulic system resources are underutilized and inefficient

Embodiment
[0038] The accessory test of a hydraulic container is a fatigue test. The use condition is to pressurize the cavity of the test piece to 10MPa at intervals of a certain period of time to test the air tightness. The high-pressure air source is only required during the fatigue test cycle, and there is no need to spend money to establish a high-pressure air source. Therefore, high-pressure cold gas cylinders are used as the gas source. The test piece has a large cavity, and after one gas cylinder is used to pressurize the two test pieces several times, the pressure drops below 10MPa, which does not meet the air pressure requirement of the 10MPa test piece and cannot be used again. Like this, for fatigue test, the required gas cylinder quantity of air pressure detection is just a lot, and the gas of remaining 10MPa is wasted in vain.

The invention belongs to the field of liquid pressure and air pressure, and particularly relates to a high-pressure gas cylinder assembly pressurization conversion device. The high-pressure gas cylinder assembly pressurization conversion device comprises a pressurizer, a control unit and a high-pressure gas cylinder assembly. Hydraulic high-pressure energy in the prior art is utilized, low-pressure gas is pressurized through the control unit and the pressurizer, and then the low-pressure gas is stored in the high-pressure gas cylinder assembly through the control unit. The hydraulic high-pressure energy in the prior art can be utilized through the device, in some places where high-pressure gas cylinders are high in consumption and the lowest use pressure is high, residual pressure in the multiple gas cylinders is pressurized and then continues to be used, and the residual pressure of the high-pressure gas cylinder assembly and the specific first-stage / second-stage pressurization capacity are utilized in the pressurization process. Resources in the prior art are fully utilized, waste is avoided, and expenditure is saved. The overall utilization efficiency is improved.

technical field [0001] The invention belongs to the fields of liquid and air pressure, and in particular relates to a pressurization conversion device for a high-pressure gas bottle assembly. Background technique [0002] Bottled high-pressure cold air is often used in many hydraulic systems, and the pressure is generally above 16MPa. In many cases, after the high-pressure cold air cylinder is used, the remaining pressure does not meet the pressure requirements for continued use, but it is still relatively high. For example, some hydraulic In the device fatigue test, it cannot be used if it is lower than 10MPa. It seems very wasteful to let go of it and buy a full pressure cylinder. Especially in places where the pressure consumption of high-pressure gas cylinders is fast and the usage is large, but the minimum operating pressure is high, the remaining pressure in many gas cylinders is all wasted. Equipping high-pressure air source is the current general solution for high-...
