[0029] Please see Figures 1 to 8 The present invention relates to a liquid-driven gas booster pump, which includes a connecting plate 10, an end plate 20, a fixing rod 30, a cylinder 40, a pipe 70, a gas passage 80, and a piston assembly 90.

[0030] The connecting plate 10 forms the driving cavity 50 and facilitates the inflow and outflow of driving fluid. Specifically, the connecting plate 10 has a first liquid channel 11, a second liquid channel 12, and a mounting hole 13. The first liquid channel 11 is arranged radially, and the second liquid channel 12 is arranged axially. One end of the first liquid channel 11 is connected to the pipe body 70, and the other end is connected to the second liquid channel 12. The second liquid channel 12 extends to the side wall of the connecting plate 10 and communicates with the driving cavity 50. The connecting plate 10 forms the end wall of the driving cavity 50. The mounting hole 13 is used to mount the fixed shaft 91, which moves along the axis within the mounting hole 13.

[0031] There are two connecting plates 10, which are parallel to each other and form a compression chamber 60 between them. The two connecting plates 10 are respectively connected to two pipe bodies 70, which are used for liquid inlet and liquid return.

[0032] There are two end plates 20, which form the compression chamber 60. The end plates 20 are used for both gas entry and exit. Specifically, the end plates 20 have a connecting hole 21, an inlet channel 22, and an outlet channel 23. The connecting hole 21 is axially aligned, and the inlet channel 22 and outlet channel 23 are located on the same straight line and radially aligned. The intersection of the inlet channel 22 and outlet channel 23 communicates with the connecting hole 21. The inlet channel 22 communicates with the inlet pipe 82 and is used for gas intake into the compression chamber 60. A one-way valve 85 is provided in the inlet channel 22; the one-way valve 85 opens when gas is intake and closes when compressed gas is output.

[0033] The fixing rod 30 is used to fix the connecting plate 10 and the end plate 20, so that the two connecting plates 10 are located between the two end plates 20. The connecting plates 10 and the end plates 20 are distributed axially. The fixing rod 30 is distributed axially and is parallel to the fixing shaft 91.

[0034] The cylindrical body 40 is used to form a cavity. In this embodiment, there are three cylindrical bodies 40. One cylindrical body 40 is fixed at both ends to two connecting plates 10, forming a driving cavity 50. The remaining cylindrical bodies 40 are fixed at both ends to the connecting plate 10 and the end plate 20, forming a compression cavity 60. The driving cavity 50 is located between the two compression cavities 60, and the driving cavity 50 and the two compression cavities 60 are on the same straight line. The driving cavity 50 and the compression cavity 60 are sealed by a sealing ring.

[0035] The tube 70 is used for the input and output of the driving fluid. There are two tubes 70. The two tubes 70 are fixed to the two connecting plates 10 respectively. The two tubes 70 are connected to the driving chambers 50 on both sides of the driving piston 92. The driving piston 92 is moved by inputting the driving fluid, thereby driving the compression piston 93 to compress air.

[0036] The gas path 80 includes an inlet 81, an inlet pipe 82, an outlet pipe 83, an outlet 84, and a one-way valve 85. The inlet 81 is connected to the inlet channel 22 and the inlet pipe 82. Both ends of the inlet pipe 82 are fixed to end plates 20, and the inlet pipe 82 delivers the gas to be compressed to the other end plate 20, which then delivers it to the distant compression chamber 60. Both ends of the outlet pipe 83 are fixed to the end plates 20, and the outlet pipe 83 is parallel to the inlet pipe 82. The outlet pipe 83 is connected to the compression chamber 60 through the outlet channel 23, and the outlet pipe 83 collects and outputs the compressed gas. The outlet 84 is connected to the outlet pipe 83. The one-way valve 85 is installed in the inlet channel 22 and the outlet channel 23 to control the direction of gas flow and prevent cross-contamination between the inlet and outlet.

[0037] The piston assembly 90 includes a fixed shaft 91, a drive piston 92, and a compression piston 93, which are fixed to the fixed shaft 91. There are two compression pistons 93, located on either side of the drive piston 92. The fixed shaft 91 is slidably mounted on two connecting plates 10. The compression pistons 93 are located in the compression chamber 60, and the drive piston 92 is located in the drive chamber 50.

[0038] In use, the hydraulically driven gas booster pump of this invention involves the driving fluid entering the driving chamber 50 from the pipe 70 through the first liquid channel 11 and the second liquid channel 12. This driving fluid causes the driving piston 92 to move within the driving chamber 50, which in turn drives the compression piston 93 to move within the compression chamber 60 via the fixed shaft 91. The gas to be compressed enters the compression chamber 60 through the inlet 81, the end plate 20, and the inlet pipe 82. The compression piston 93 compresses the gas, and the compressed gas is output from the outlet 84 through the outlet pipe 83. This hydraulically driven gas booster pump features a liquid-driven driving chamber 50 in the middle, resulting in high driving force; and compression chambers 60 at both ends, providing high compression efficiency.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
