Description

Technical Field

[0001] This utility model relates to the technical field of booster pumps, specifically a gas booster pump. Background Technology

[0002] A gas booster pump uses low-pressure gas at a large-area piston end to drive a small-area piston end to generate high-pressure gas. It can be used to compress air or other gases, and the output gas pressure can be steplessly adjusted by the driving gas pressure.

[0003] Traditional gas booster pumps compress incoming gas by controlling airflow to drive a piston in a reciprocating motion within a piston chamber, thus boosting the output gas. However, traditional gas booster pumps only perform work in one direction; they do not perform work or output high pressure when the piston retracts. This reduces efficiency and wastes resources.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0005] This utility model addresses the above-mentioned technical problems by providing a gas booster pump. The piston rod inside the cylinder drives the piston to do work during its bidirectional reciprocating motion, meaning that it has high-pressure output during each bidirectional motion, thereby improving efficiency and reducing energy waste.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A gas booster pump includes a front high-pressure cylinder, a booster pump cylinder, and a rear high-pressure cylinder that are coaxially connected in sequence at intervals. A front high-pressure piston, a booster piston, and a rear high-pressure piston are correspondingly provided inside the cylinder and connected as a whole by a piston rod. The inner diameters of the front high-pressure cylinder and the rear high-pressure cylinder are both smaller than the inner diameter of the booster pump cylinder.

[0008] The front high-pressure cylinder and the rear high-pressure cylinder are each provided with a one-way low-pressure intake port and a one-way high-pressure output port.

[0009] The booster pump cylinder has a first vent at one end and a second vent at the other end. The air intake of the booster pump cylinder switches between the first vent and the second vent to ensure that the piston rod has high pressure output during its back-and-forth movement.

[0010] The gas booster pump has air inlets at both ends of the booster cylinder, namely the first air inlet and the second air inlet. By switching between them, air can be introduced in different directions. The booster piston can do work by moving back and forth. High pressure output is achieved through the high pressure output ports at both ends of the front high pressure cylinder and the rear high pressure cylinder. Compared with booster pumps that do work in one direction, this improves the efficiency of high pressure output and reduces energy waste.

[0011] In a further optimized design, the front high-pressure cylinder, the booster pump cylinder, and the rear high-pressure cylinder are respectively connected to a front cover, a rear cover, a front middle cover, and a rear middle cover at both ends and in the middle. The front cover, the front high-pressure cylinder, the front middle cover, the booster pump cylinder, the rear middle cover, the rear high-pressure cylinder, and the rear cover are connected sequentially, which facilitates the manufacturing and installation of the gas booster pump.

[0012] In a further optimized design, the front cover, front middle cover, rear middle cover, and rear cover each have a low-pressure intake port on one side and a high-pressure output port on the other side. The placement of the low-pressure intake port and high-pressure output port on the front cover, front middle cover, rear middle cover, and rear cover facilitates manufacturing, use, and installation.

[0013] In a further optimized design, the low-pressure inlet and high-pressure outlet are connected to one-way valves to achieve one-way air intake or one-way air output.

[0014] To further optimize the design, the first and second vents are connected to solenoid valves to switch the air intake. The solenoid valves enable switching of air intake at both ends of the booster pump cylinder, ensuring stable and reliable reciprocating motion of the booster piston.

[0015] To further optimize the design, a magnetic ring is installed on the booster piston, and magnetic switches are respectively installed at both ends of the booster pump cylinder. When the booster piston moves to the position of the magnetic switch, the two mutually induce each other to trigger the solenoid valve to switch direction. The mutual induction between the magnetic ring and the magnetic switch to trigger the solenoid valve ensures accurate and reliable positioning of the booster piston during its back-and-forth movement.

[0016] In a further optimized design, a front heat-insulating cylinder and a rear heat-insulating cylinder are respectively fitted onto the outside of the front high-pressure cylinder and the rear high-pressure cylinder, forming a front heat-insulating cavity and a rear heat-insulating cavity respectively between their inner and outer surfaces. The front and rear heat-insulating cylinders isolate the high temperatures on the surfaces of the front and rear high-pressure cylinders, preventing the high temperatures from affecting operators, surrounding components, and the environment.

[0017] In a further optimized design, the exhaust gas from the first and second vents is connected by pipelines and then discharged through the front and rear heat insulation chambers, respectively. The exhaust gas from the booster pump cylinder passes through the front and rear heat insulation chambers, assisting in the heat dissipation of the front and rear high-pressure cylinders, enabling waste gas reuse and saving energy; moreover, it facilitates rapid cooling of the front and rear high-pressure cylinders, ensuring stable and reliable operation.

[0018] In a further optimized design, the first and second vents are connected to solenoid valves to switch the air intake, and the exhaust is discharged after passing through the solenoid valve pipeline to the front insulation chamber and the rear insulation chamber.

[0019] Further optimization of the solution also includes a gas source and a gas source dual unit, wherein the gas source is connected to the solenoid valve through the gas source dual unit.

[0020] In a further optimized design, the gas source dual unit is connected to the low-pressure intake port via a one-way valve.

[0021] In a further optimized design, the low-pressure inlets are connected as a single unit via low-pressure air intake pipes, and the high-pressure outlets are connected as a single unit via high-pressure air output pipes. Connecting the low-pressure inlets via low-pressure air intake pipes facilitates the connection and use of the low-pressure air intake lines, while connecting the high-pressure outlets via high-pressure air output pipes facilitates the connection and use of the high-pressure air output lines.

[0022] Compared with the prior art, the gas booster pump of this utility model has the following technical advantages:

[0023] 1. The piston's bidirectional working structure eliminates the energy consumption of the idle stroke, saving energy compared to traditional unidirectional booster pumps;

[0024] 2. The exhaust gas from the booster pump is used to cool the front and rear high-pressure cylinders, achieving self-circulation cooling and ensuring the stability of continuous operation of the high-pressure cylinder.

[0025] 3. Magnetic induction non-contact commutation solves the problem of mechanical contact wear and failure, ensuring the reliability of control. Attached Figure Description

The exhaust gas from the booster pump cylinder 4 passes through the front heat insulation chamber 21 and the rear heat insulation chamber 22, assisting in the heat dissipation of the front high-pressure cylinder 2 and the rear high-pressure cylinder 6, realizing the reuse of exhaust gas and saving energy; moreover, it is beneficial to the rapid cooling of the front high-pressure cylinder 2 and the rear high-pressure cylinder 6, ensuring stable and reliable operation.

[0044] like Figure 5 As shown, the gas booster pump also includes a gas source 23 and a gas source duplex 24, with the gas source 23 connected to the solenoid valve 17 via the gas source duplex 24.

[0045] like Figure 5 As shown, the air source dual unit 24 is connected to the low-pressure inlet 12 through the one-way valve 16.

[0046] like Figure 1 and Figure 3As shown, the low-pressure inlet 12 is connected to the high-pressure outlet 13 via the low-pressure intake pipe 25, and the high-pressure outlet 13 is connected to the high-pressure outlet pipe 26. The low-pressure intake pipe 25 connects the low-pressure inlet 12 to facilitate the connection and use of the low-pressure intake pipe 25, and the high-pressure outlet pipe 26 connects the high-pressure outlet 13 to facilitate the connection and use of the high-pressure outlet 13 gas pipeline.

[0047] like Figure 1 and Figure 3 As shown, a junction box 28 is connected to the end of the front cover 1, which contains a micro electric controller (not shown in the figure); the micro electric controller controls the switching action of the solenoid valve 17 through the sensing signal of the magnetic ring 18 and the magnetic switch.

[0048] The piston rod inside the cylinder of this gas booster pump drives the piston to do work during its bidirectional reciprocating motion, meaning that it has high-pressure output during each bidirectional motion, thereby improving efficiency and reducing energy waste.
