Technical Field

[0001] This invention relates to the field of high-pressure gas drive device technology, and in particular to a high-power, high-energy gas source system and control method. Background Technology

[0002] With the continuous development of fluid machinery technology, the requirements for fluid machinery systems to rapidly drive high-power, high-load products are becoming increasingly stringent. Currently, the two most widely used rapid drive circuits are the hydraulic cylinder differential connection rapid motion circuit and the rapid motion circuit using a dual-pump oil supply system, both of which predominantly employ hydraulic drive. However, the volume change of a liquid under pressure at room temperature is extremely small, leading to these two types of rapid circuits being primarily used for driving low-power, low-load products. Therefore, there is a need to develop a high-power, high-energy air source system and control method capable of rapid action under ultra-high loads. Summary of the Invention

[0004] The specific technical solution is as follows: A high-power, high-energy gas source system includes an energy storage module, a fast drive module, a control oil accumulator, and a replenishing solenoid valve. There are multiple energy storage modules and fast drive modules. Each energy storage module is connected to a corresponding fast drive module. The energy storage modules are connected to each other through a high-pressure ball valve. The energy storage module is connected to a replenishing hose.

[0023] The substantive features and advantages of the present invention will be further described below with reference to examples, but the present invention is not limited to the listed embodiments.

[0024] like Figures 1 to 3 As shown, this embodiment of a high-power, high-energy gas source system includes an energy storage module 100, a rapid drive module 200, a control oil accumulator 20, and a replenishing solenoid valve 8. Multiple energy storage modules 100 and rapid drive modules 200 are included, with each energy storage module 100 correspondingly connected to one rapid drive module 200. The energy storage modules 100 are connected via high-pressure ball valves 19 and are connected to replenishing hoses 23. Each energy storage module 100 includes a high-pressure nitrogen cylinder 10. The control oil accumulator 20 is connected to the rapid drive module 200 and is connected to the replenishing hose 23 via the replenishing solenoid valve 8. In this technical solution, multiple energy storage modules 100 are separated by high-pressure ball valves 19, and each energy storage module has an independent charging port and pressure measuring point, ensuring that each energy storage module can operate independently. This embodiment uses three energy storage modules and three rapid drive modules, with a maximum drive load of 150T. A large-volume 275L high-pressure nitrogen cylinder is used to ensure sufficient gas compression, enabling a continuous and rapid supply of high-pressure, high-flow-rate hydraulic oil, thus achieving rapid response to ultra-high loads. Through this technical solution, when replenishing the hydraulic oil in the hydraulic system, even though the liquid volume has changed, the high-pressure gas can continue to maintain the hydraulic oil pressure, preventing a rapid loss of pressure due to a decrease in the volume of hydraulic oil in the container caused by replenishment.

[0025] In this embodiment, the energy storage module 100 includes a main accumulator 9, which is connected to the high-pressure nitrogen cylinder 10 via a gas shut-off valve 14. An inflation valve 18 is provided between the main accumulator 9 and the high-pressure nitrogen cylinder 10. The high-pressure nitrogen cylinder is sealed by the combination of two inflation valves and the gas shut-off valve 14, extending its service life. In this embodiment, the main accumulator 9 is connected to the drain hose 24 via a drain ball valve 12 and a drain ball valve 11, thereby controlling the discharge of oil through the drain hose 24. In this embodiment, the high-pressure nitrogen cylinder 10 has a capacity of 275L, the main accumulator 9 has a capacity of 400L, and the control oil accumulator 20 has a capacity of 10L. Both the main accumulator and the control oil accumulator are piston-type accumulators.

[0026] In this embodiment, the rapid drive module 200 includes a main accumulator replenishing solenoid valve 5, which is connected to the main accumulator 9. The rapid drive module 200 includes a hydraulically controlled check valve 3 and three two-way cartridge valves 2. Each hydraulically controlled check valve 3 is connected to the main accumulator replenishing solenoid valve 5 and the two-way cartridge valve 2, respectively. The two-way cartridge valve 2 is connected to the outlet high-pressure hose 25. The rapid drive module 200 includes a control oil solenoid valve 7, which is connected to the control oil accumulator 20 and the hydraulically controlled check valves 3. The rapid drive module 200 includes a drain solenoid valve 6, which is connected to the control oil solenoid valve 7, the hydraulically controlled check valves 3, and the drain hose 22.

[0027] In this embodiment, a control cover assembly 1 is provided above the two-way cartridge valve 2, and the outlet high-pressure hose 25 is controlled by the outlet high-pressure ball valve 4 to control the oil output. The energy storage module 100 includes a gas safety valve 15, a pressure gauge 16, and a pressure gauge switch 17 to monitor the gas pressure and improve safety. The main accumulator 9 is provided with a pressure test connector 13 for testing pressure. The high-power high-energy gas source system of this embodiment uses four piston accumulators (three 400L accumulators and one 10L accumulator, of which the 10L accumulator is a control oil accumulator) to maintain pressure. The valve core position is controlled by electromagnetic control. When the fast drive circuit is turned on, multiple main accumulators supply oil to the actuator (such as a hydraulic cylinder) to achieve the purpose of rapid movement of high-load products. In addition, the device uses a large-volume high-pressure nitrogen cylinder with a large gas compression capacity, which makes its drive action response fast and its load capacity strong. Maximum system working pressure: 32MPa; Sealing pressure holding: Under normal temperature and constant volume, the pressure drop over 90 days is ≤0.2MPa; Maximum flow rate: 2000L / min; Working medium: nitrogen and hydraulic oil.

[0028] A control method for a high-power, high-energy gas source system includes the following steps: a) Opening the high-pressure ball valve 21 of the control oil circuit of the control oil accumulator 20 to complete the nitrogen filling of the gas chamber of the control oil accumulator 20; b) First opening the gas shut-off valve 14, then opening the drain ball valve 12 and the discharge ball valve 11 to complete the nitrogen filling of the gas chamber of the main accumulator 9 and the high-pressure nitrogen cylinder 10; c) Energizing the oil replenishing solenoid valve 8 of the control oil accumulator to complete the oil filling of the liquid chamber of the control oil accumulator 20 through the oil replenishing hose 23; d) De-energizing the oil replenishing solenoid valve 8 of the control oil accumulator and energizing the oil replenishing solenoid valve 5 of the main accumulator to complete the oil filling of the liquid chamber of the main accumulator 9 through the oil replenishing hose 23; e) Energizing the drain solenoid valve 6 and then energizing the control oil solenoid valve 7, so that the main accumulator power source delivers oil to the hydraulic system to complete the rapid action under ultra-high load.

[0029] In the above technical solution, in order to protect the oil pressure sealing and oil synchronization in the fast drive circuit, a combination of three hydraulic control check valves is used to control the oil outlet of each piston accumulator. When the two-position two-way control solenoid 7 is energized, the hydraulic check valve will be reversed and the three 400L piston accumulators will supply oil to the hydraulic system at the same time.

[0030] This embodiment presents a high-power, high-energy gas source system and control method. Because gas has much greater compressibility elasticity, it can maintain a relatively high pressure even under significant volume changes. Therefore, when the accumulator replenishes hydraulic oil in the hydraulic system, even though the liquid volume has changed, the high-pressure gas can continue to maintain the hydraulic oil pressure, preventing a rapid loss of pressure due to a decrease in the volume of hydraulic oil in the container caused by replenishment. Furthermore, each piston-type accumulator has an independent charging port and pressure measuring point, ensuring that each piston-type accumulator can operate independently, with a maximum drive load of up to 150T. It can continuously and rapidly provide high-pressure, high-flow-rate hydraulic oil, thereby achieving rapid response to ultra-high loads.

[0031] It should be noted that the above preferred embodiments are merely illustrative of the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
