Description

Technical Field

[0001] This utility model belongs to the technical field of reciprocating compressors, and in particular relates to a high-pressure nitrogen reciprocating compressor. Background Technology

[0002] In the nitrogen production process, reciprocating compressors play a crucial role in many aspects. They compress nitrogen by changing the volume of the cylinder through the reciprocating motion of a piston. Many subsequent processes and equipment in nitrogen production (such as nitrogen storage devices, pipelines, and gas-using equipment) require nitrogen at a certain pressure to function properly. Reciprocating compressors can boost low-pressure nitrogen to the required high-pressure state to meet the needs of different application scenarios.

[0003] The valves of existing nitrogen reciprocating compressors are all located inside the compressor, at right angles to the suction and discharge pipes. After the nitrogen is accelerated by the piston in the reciprocating compressor, it still needs to pass through the valves and right-angle pipes, which increases the power loss of the compressor and reduces its working efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a high-pressure nitrogen reciprocating compressor, comprising:

[0005] A drive motor is fixed on the base and serves as a drive device; a reciprocating compressor is fixed on the base and connected to the drive motor via a belt; one end of the belt is sleeved on the output end of the drive motor, and the other end is sleeved on the pulley on the side of the reciprocating compressor.

[0006] Preferably, the reciprocating compressor includes a drive section and a piston section, wherein the drive section and the piston section are fixedly connected by bolts.

[0007] Preferably, the drive unit is equipped with a piston assembly, which includes a rocker arm, a cam, and a piston rod. The upper and lower ends of the rocker arm are movably connected to the piston rod and the cam, respectively, via rotating shafts.

[0008] Preferably, a drive shaft is mounted on one side of the cam, and the pulley is fixed to the drive shaft.

[0009] Preferably, the piston rod is placed in the piston section, and the piston section is respectively connected to an inlet check valve and an outlet check valve.

[0010] Preferably, the outer surface of the piston portion is provided with heat dissipation fins.

[0011] The beneficial effects of this utility model are:

[0012] This invention moves the built-in valve to the outermost end of the intake and exhaust pipes, allowing nitrogen to immediately enter the straight pipe structure after being pressurized and accelerated by the piston and leaving the one-way valve. This eliminates the pressure reduction caused by traditional bends and right-angle pipes, ensuring the efficiency of the reciprocating compressor and effectively improving the nitrogen pressurization effect.

[0013] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 3 As shown, this embodiment provides a high-pressure nitrogen reciprocating compressor, including: a drive motor 1, which is fixed on a base 2 as a drive device; a reciprocating compressor 3, which is fixed on the base 2 and connected to the drive motor 1 via a belt 4; one end of the belt 4 is sleeved on the output end of the drive motor 1, and the other end is sleeved on a pulley 5 on the side of the reciprocating compressor 3, so that the reciprocating compressor 3 is driven to work by starting the drive motor 1.

[0023] The reciprocating compressor 3 includes a drive section 6 and a piston section 7, which are fixedly connected to each other by bolts. A piston assembly 8 is installed in the drive section 6, which includes a rocker arm 9, a cam 10, and a piston rod 11. The upper and lower ends of the rocker arm 9 are movably connected to the piston rod 11 and the cam 10 respectively via rotating shafts. A drive shaft 12 is installed on one side of the cam 10, extending through the side wall of the reciprocating compressor 3 and movably connected to the reciprocating compressor 3 via ball bearings. The pulley 5 is fixed to the drive shaft 12 and is driven by a belt 4. When the drive motor 1 starts, the pulley 5 is driven to rotate by the belt 4. At this time, the drive shaft 12 rotates along with the pulley 5, causing the cam 10 to rotate around the drive shaft, thereby pulling the rocker arm 9 and the piston rod 11 up and down, serving as the basis for the reciprocating flow of nitrogen.

[0024] The piston rod 11 is placed in the piston section 7, which is connected to a conventional inlet check valve 13 and an outlet check valve 14. Both the inlet check valve 13 and the outlet check valve 14 are located at the outermost straight section of the pipeline to ensure that the compressed nitrogen maintains its speed and pressure after passing the outlet check valve 14, reducing pressure and speed attenuation caused by pipeline bends and effectively improving nitrogen pressurization efficiency. The outer surface of the piston section 7 is provided with heat dissipation fins 15. Since the piston section 7 generates a large amount of heat during continuous operation, efficient heat dissipation through the heat dissipation fins 15 is necessary.

[0025] All the devices selected in this application (parts whose specific structures are not specified) are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
