Description

Technical Field

[0001] This utility model relates to the field of booster device technology, and in particular to a high-pressure booster device. Background Technology

[0002] In scenarios such as high-pressure sealing testing of precision components, high-pressure cleaning of large equipment, and high-pressure gas injection in energy extraction, high-pressure booster devices are core components ensuring the stable operation of downstream equipment. Their pressure rating, flow stability, and operational reliability directly determine operational efficiency and accuracy. Currently, single-pump booster systems are widely used in low-pressure, low-flow scenarios such as driving small pneumatic tools and local equipment gas replenishment due to their simple structure, fewer parts, and low procurement costs. However, as downstream demands upgrade towards higher pressure, larger flow, and more stable operation, their inherent shortcomings are becoming increasingly apparent: single-pump pressurization relies entirely on the piston movement of a single cylinder. Increasing the output pressure requires increasing the compression ratio, but this reduces the cylinder volume, leading to a decrease in flow rate. Expanding the cylinder to increase flow rate is limited by driving power and material strength, making it impossible to achieve high pressure levels. It is difficult to balance flow rate and pressure, thus requiring a high-pressure booster device. Utility Model Content

[0003] The purpose of this invention is to provide a high-pressure boosting device to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A high-pressure booster device includes a first booster pump, a second booster pump, a third booster pump, a main pipeline, and air sources. The first, second, and third booster pumps have identical structures. The air outlet of the booster chamber of the first booster pump is connected to the left end of the main pipeline, the air outlet of the booster chamber of the second booster pump is connected to the middle section of the main pipeline, and the air outlet of the booster chamber of the third booster pump is connected to the right end of the main pipeline. A first pressure control valve is installed on the main pipeline between the air outlets of the first and second booster pumps, and a second pressure control valve is installed on the main pipeline between the air outlets of the second and third booster pumps. Multiple air sources are provided, and each air source is connected to the first, second, and third booster pumps respectively.

[0006] By adopting the above technical solution, three identical booster pumps achieve pressure output in the left, middle, and right sections of the main pipeline, forming a multi-pump parallel booster structure. This effectively superimposes the output flow and increases the overall pressure in the main pipeline. At the same time, the first and second pressure control valves can regulate the pipeline pressure between adjacent booster pumps, avoiding pressure imbalance in the main pipeline caused by fluctuations in the output of a single pump. This ensures the stability and continuity of the output pressure of the entire device. Furthermore, the identical booster pumps facilitate later maintenance and replacement, reducing equipment operation and maintenance costs.

[0007] In a further embodiment, the first booster pump includes:

[0008] The first cylinder has an air inlet and an air outlet at the top of its inner wall, and a drive piston that moves along the axis of the first cylinder is disposed inside the first cylinder.

[0009] The second cylinder has a first air vent at the bottom of its inner wall and a second air vent at the top of its inner wall. The second cylinder is coaxially arranged with the first cylinder. A booster piston is provided inside the second cylinder. The second cylinder is fixedly installed on the top of the first cylinder.

[0010] A connecting rod, one end of which is fixedly connected to the drive piston, and the other end of which passes through the second cylinder and is fixedly connected to the booster piston. The connecting rod is used to drive the drive piston and the booster piston to reciprocate synchronously.

[0011] A trigger switch is provided, and multiple trigger switches are respectively fixedly installed at the bottom end and the top end of the second cylinder body.

[0012] By adopting the above technical solution, the drive piston achieves power output by taking in air through the intake port and venting air through the exhaust port. The booster piston completes the air path switching by relying on the air exchange port of the second cylinder, thereby realizing the volume change and pressure increase of the booster chamber. The trigger switches at the bottom and top of the second cylinder can accurately detect the end point of the reciprocating stroke of the booster piston, providing position signals for subsequent air path switching, ensuring the accuracy of piston movement, avoiding overtravel damage, and further improving the operational reliability of the booster pump.

[0013] In a further embodiment, a reversing valve is also included. The first and second air vents of the second cylinder are respectively connected to the top of the reversing valve. The bottom of the reversing valve is connected to an air source and a muffler. The trigger switch is signal-connected to the reversing valve and is used to switch the reversing valve.

[0014] By adopting the above technical solution, after the trigger switch detects that the booster piston has reached the end of its stroke, it can send a signal to the reversing valve in real time to control the reversing valve to switch the air path direction of the second cylinder. Through the alternating intake and exhaust of the first and second air exchange ports, the booster piston is driven to achieve reciprocating cycle motion. The automatic boosting operation can be completed without manual intervention, which greatly improves the operating efficiency of the device. At the same time, the muffler connected to the bottom of the reversing valve can effectively reduce the airflow noise during air path switching and reduce noise pollution during equipment operation. The air source provides a stable power source for the reversing valve and the second cylinder, ensuring the timeliness and smoothness of air path switching.

[0015] In a further embodiment, the right end of the main pipeline is connected to one end of a high-pressure output pipeline, and the other end of the high-pressure output pipeline is connected to a third pressure control valve.

[0016] By adopting the above technical solution, the high-pressure gas collected in the main pipeline can be transported to the downstream pressure-using equipment through the high-pressure output pipeline, realizing the effective transmission of high pressure; the third pressure control valve can accurately regulate the final output pressure in the high-pressure output pipeline. When the pressure in the pipeline exceeds the set value, it can automatically release pressure or shut off to prevent downstream equipment from being damaged due to overpressure. At the same time, it can also cooperate with the upstream booster pump to compensate for pressure when the pressure is insufficient, ensuring that the output pressure always meets the pressure requirements and providing a safe and stable pressure guarantee for the operation of downstream equipment.

[0017] In a further embodiment, the air inlet of the first cylinder is connected to a first one-way valve, the air outlet of the first cylinder is connected to a second one-way valve, and an exhaust port is provided at the inner bottom of the first cylinder, with a muffler fixedly installed in the exhaust port.

[0018] In a further embodiment, a first pressure sensor, a second pressure sensor, and a third pressure sensor are also included; the first pressure sensor is disposed to the left of the first pressure control valve and is used to detect the output pressure of the first booster pump; the second pressure sensor is disposed between the first pressure control valve and the second pressure control valve and is used to detect the output pressure of the second booster pump; the third pressure sensor is disposed on the high-pressure output pipeline and is used to detect the output pressure of the third booster pump.

[0019] By adopting the above technical solution, the three pressure sensors can monitor the pressure data at their respective locations in real time: the first pressure sensor monitors the output pressure of the first booster pump, the second pressure sensor monitors the output pressure of the second booster pump, which can promptly detect pressure anomalies in a single booster pump, facilitate quick location of the faulty pump, and reduce the difficulty of troubleshooting; the third pressure sensor monitors the pressure in the high-pressure output pipeline, and can provide real-time feedback on the final output pressure status, providing data for the adjustment of the third pressure control valve and realizing closed-loop control of the output pressure.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. High-pressure gas collected through the main pipeline can be transported to downstream pressure-using equipment through the high-pressure output pipeline, realizing the effective transmission of high pressure; the third pressure control valve can accurately regulate the final output pressure in the high-pressure output pipeline. When the pressure in the pipeline exceeds the set value, it can automatically release pressure or shut off to prevent downstream equipment from being damaged due to overpressure. At the same time, it can also cooperate with the upstream booster pump to compensate for pressure when the pressure is insufficient, ensuring that the output pressure always meets the pressure requirements, and providing a safe and stable pressure guarantee for the operation of downstream equipment.

Multiple air sources 5 are provided, and the multiple air sources 5 are respectively connected to the first booster pump 1, the second booster pump 2, and the third booster pump 3.

[0029] The first booster pump 1 includes a first cylinder 11, with an air inlet and an air outlet at the top of its inner wall. A drive piston 16, which moves along the axis of the first cylinder 11, is disposed inside the first cylinder 11. A second cylinder 12 has a first vent hole at the bottom of its inner wall and a second vent hole at the top of its inner wall. The second cylinder 12 is coaxial with the first cylinder 11 and contains a booster piston 15. The second cylinder 12 is fixedly mounted on the top of the first cylinder 11. A connecting rod 13 has one end fixedly connected to the drive piston 16 and the other end passing through the second cylinder 12 and fixedly connected to the booster piston 15. The connecting rod 13 drives the drive piston 16 and the booster piston 15 to reciprocate synchronously. Multiple trigger switches 14 are also included, each fixedly mounted on the bottom and top of the second cylinder 12.

[0030] It also includes a reversing valve 8. The first and second air vents of the second cylinder 12 are respectively connected to the top of the reversing valve 8. The bottom of the reversing valve 8 is connected to the air source 5 and the muffler 10. The trigger switch 14 is connected to the reversing valve 8. The trigger switch 14 is used to switch the reversing valve 8. The reversing valve 8 can be a two-position five-way reversing valve 8.

[0031] The right end of the main pipe 4 is connected to one end of the high-pressure output pipe, and the other end of the high-pressure output pipe is connected to the third pressure control valve 9. The air inlet of the first cylinder 11 is connected to the first one-way valve, and the air outlet of the first cylinder 11 is connected to the second one-way valve. An exhaust port is opened at the inner bottom of the first cylinder 11, and a muffler 10 is fixedly installed in the exhaust port.

[0032] It also includes a first pressure sensor 17, a second pressure sensor 18, and a third pressure sensor 19; the first pressure sensor 17 is disposed to the left of the first pressure control valve 6 and is used to detect the output pressure of the first booster pump 1; the second pressure sensor 18 is disposed between the first pressure control valve 6 and the second pressure control valve 7 and is used to detect the output pressure of the second booster pump 2; the third pressure sensor 19 is disposed on the high-pressure output pipeline and is used to detect the output pressure of the third booster pump 3.

[0033] Specific implementation process: After the device is started, when the gas source 5 supplies gas to the first cylinder 11 of the first booster pump 1, the gas enters the first cylinder 11 through the first one-way valve connected to the air inlet, pushing the drive piston 16 in the cylinder to move downward along the axis of the first cylinder 11. At the same time, the drive piston 16 moves downward, driving the booster piston 15 in the second cylinder 12 to move downward synchronously through the connecting rod 13. At this time, the first air exchange port at the bottom of the second cylinder 12 is in the air outlet state, and the gas enters the lower chamber of the second cylinder 12 to assist in pushing the booster piston 15 downward. When the booster piston 15 moves downward to the top of the second cylinder 12, it will trigger the trigger switch 14 installed at the bottom of the second cylinder 12. The trigger switch 14 then sends an electrical signal to the reversing valve 8 to control the reversing valve 8 to switch the gas path. After the reversing valve 8 switches, the gas source 5 supplies gas to the first air exchange port of the second cylinder 12, and at the same time, the second The vent is connected to the muffler 10 via the reversing valve 8 to prepare for exhaust. After air enters through the first vent, it pushes the booster piston 15 to move upward along the axis of the second cylinder 12. The connecting rod 13 simultaneously drives the drive piston 16 to return to its original position. When the drive piston 16 moves upward, the exhaust gas in the first cylinder 11 is discharged through the exhaust port at the bottom of the inner end. During the exhaust process, the muffler 10 on the exhaust port reduces airflow noise. When the booster piston 15 moves upward, the volume of the upper chamber of the first cylinder 11 decreases, compressing the gas in the chamber again and continuously outputting high-pressure gas to the main pipe 4 through the exhaust port. When the booster piston 15 moves upward to the bottom of the second cylinder 12, it triggers the trigger switch 14 at the top of the inner end. The trigger switch 14 sends a signal to the reversing valve 8 again, and the reversing valve 8 switches back to the initial air path. The booster piston 15 moves downward again, forming an upward boosting and downward reset cycle, realizing continuous boosting output of a single pump. At the same time, the first, second, and third booster pumps 3 synchronously output high-pressure gas to the left, middle, and right ends of the main pipeline 4, respectively, forming a boosting effect of multiple pumps in parallel. The superimposed output flow causes the overall pressure in the main pipeline 4 to gradually increase. During the continuous operation of the device, each time the drive piston 16 of each booster pump completes a downward reset, the exhaust gas of the first cylinder 11 will be discharged through the exhaust port and the muffler 10, which not only ensures normal air exchange of the cylinder but also reduces exhaust noise. At the same time, when the reversing valve 8 switches the air path, the muffler 10 connected at the bottom end synchronously reduces the airflow noise generated by the air path switching, thus optimizing the overall operating environment of the device.
