[0015] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0016] like Figures 1 to 2 The diagram shown is a structural schematic of the novel high-pressure pneumatic diaphragm pump provided by this utility model. The novel high-pressure pneumatic diaphragm pump includes a pump body 10, a pressurization system 20 mounted on the pump body 10, and a connecting air pipe 30 connecting the pump body 10 and the pressurization system 20. It is conceivable that the novel high-pressure pneumatic diaphragm pump also includes other functional modules such as an air source and gas valves, which are technologies well known to those skilled in the art and will not be described in detail here.

[0017] The pump body 10 is a pneumatic diaphragm pump. The pneumatic diaphragm pump is a prior art. For example, the working principle of the pneumatic diaphragm pump is mentioned in the Chinese invention CN202211014241.2, which discloses a pneumatic diaphragm pump valve chamber and a pneumatic diaphragm pump. Therefore, only a brief description is given here.

[0018] The pump body 10 is provided with an air inlet 11 and two mounting protrusions 12. The air inlet 11 connects to the air chamber of the pump body 10 to supply air to the air chamber, enabling the piston inside the air chamber to move. The corresponding structure and working principle are common technologies in the field of pneumatic diaphragm pumps and are not the main content of this application, so only a brief description is given here. The mounting protrusions 12 are two rectangular block protrusions, with their protrusion direction from the pump body 10 toward the direction away from the ground, for mounting and fixing the booster system 20.

[0019] The booster system 20 includes a mounting bracket 21 disposed on the pump body 10, and a booster device 22 disposed on the mounting bracket 21.

[0020] The mounting bracket 21 includes a device mounting plate 211, two fixing arms 212 connected to the device mounting plate 211, and two fastening ends 213 disposed on the free ends of the fixing arms 212.

[0021] The equipment mounting plate 211 is a fixed plate, and a plurality of fixing holes for inserting fasteners are arranged on the plate surface. The supercharging equipment 22 is placed on the equipment mounting plate 211, and is fixed by using fasteners, so as to realize the fixation of the supercharging equipment 22. The extension direction of the equipment mounting plate 211 is perpendicular to the protruding direction of the mounting protrusion 12, that is, the equipment mounting plate 211 is parallel to the ground, so as to ensure the stability of the supercharging equipment 22 placed on the equipment mounting plate 211.

[0022] The fixed force arm 212 is a sector-shaped arc, and the center of the sector-shaped arc is located on the side away from the equipment mounting plate 211, so that the fixed force arm 212 can be attached to the pump body 10 when the mounting bracket 21 is mounted on the pump body 10.

[0023] The clamping end 213 is located on the free end of the fixed force arm 212 away from the equipment mounting plate 211, can be clamped on the mounting protrusion 12, and is provided with a screw hole for inserting a fastener, so as to ensure that the mounting bracket 21 is firmly fixed on the pump body 10.

[0024] The supercharging equipment 22 is an air supercharging valve, and the main function is to increase the pressure of low-pressure gas by compression, so as to supply high-pressure systems. The working principle is that low-pressure gas on a large-area piston end drives a small-area piston end to generate high-pressure fluid. The supercharging equipment 22 is a prior art widely used in the field of mechanical production, and should be well known to those skilled in the art. Therefore, only the function is briefly described here. The supercharging equipment 22 includes an air inlet connector and an air outlet connector. The air inlet connector is connected to a low-pressure gas source to supply gas.

[0025] The connecting air pipe 30 is a high-pressure air pipe, one end of which is connected to the air outlet connector of the supercharging equipment 22, and the other end is connected to the air inlet 11, so as to send high-pressure gas pressurized by the supercharging equipment 22 into the pump body 10, and provide high-pressure gas for the pneumatic diaphragm pump to work.

[0026] In use, when the pneumatic diaphragm pump needs low-pressure delivery conditions, the supercharging equipment 22 is closed, and low-pressure gas enters the air inlet 11. When the pneumatic diaphragm pump group needs high-pressure delivery conditions, the supercharging equipment 22 is opened, and low-pressure gas pressurized by the supercharging equipment 22 is input into the air inlet 11.

[0027] Compared with the prior art, the novel high-pressure pneumatic diaphragm pump provided by the utility model has the ability to convert low-pressure gas into high-pressure gas by setting the pressure increasing system 20 and installing the pressure increasing device 22 on the pump body 10, without the need to input high-pressure gas source, thereby reducing the requirement for the gas source and reducing the production cost. Since the product is provided with a pressure increasing device, the pressure increasing device does not need to be additionally equipped during work, the installation and use of the equipment are facilitated, the equipment is applicable to various production scenes, meanwhile, the problems of interface gas leakage, insufficient gas pressure and the like caused by multiple connections and disconnections of the pressure increasing device are avoided, the gas consumption is low, and the product working efficiency is high.

[0028] The above is only the preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement and the like within the utility model spirit are covered in the claim range of the utility model.
