Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation air compressor technology, specifically a self-cooling mechanism for a magnetic levitation air compressor. Background Technology

[0002] A magnetic levitation air compressor is a permanent magnet motor that uses magnetic force to levitate and rotate the rotor at high speed. By levitizing the rotor, the rotor and stator of the magnetic levitation air compressor do not contact each other, thus eliminating frictional losses. Magnetic levitation air compressors are highly efficient and have a long lifespan. Compared to traditional air compressors, magnetic levitation air compressors do not have gears for speed increase and do not require lubricating oil to reduce friction.

[0003] However, due to the high-power rotation of the rotor of the magnetic levitation air compressor, the compressor temperature will be too high. The cooling range needs to be adjusted according to the compressor speed, which will result in the lubricating oil temperature being too low, making it difficult for the oil film to form in the magnetic levitation bearing, increasing the contact friction between the rotor and the bearing, and increasing energy consumption. Utility Model Content

Detailed Implementation

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

[0022] Please see Figures 1-6 This utility model provides an embodiment of a self-cooling mechanism for a magnetic levitation air compressor, comprising a magnetic levitation air compressor body 1, a plurality of support seats 5 fixedly disposed at the bottom of the magnetic levitation air compressor body 1, an output shaft 6 fixedly disposed at the center of the magnetic levitation air compressor body 1, a transmission mechanism 4 fixedly disposed on the output shaft 6, a cooling mechanism 3 fixedly disposed at the top of the magnetic levitation air compressor body 1 near the output shaft 6, and a piston mechanism 2 sleeved on the magnetic levitation air compressor body 1. The operation of the magnetic levitation air compressor body 1 drives the output shaft 6 to rotate, which in turn drives the transmission mechanism 4 to operate, which in turn drives the piston mechanism 2 to reciprocate. This reciprocating piston movement draws cold air from inside the cooling mechanism 3 into the piston mechanism 2, thereby cooling the magnetic levitation air compressor body 1.

[0023] Specifically, the transmission mechanism 4 includes a first transmission shaft 41, a first transmission gear 42, a second transmission gear 43, a transmission belt 44, a second transmission shaft 45, and an H-shaped fixing plate 46. The H-shaped fixing plate 46 is fixedly mounted on the top of the magnetic levitation air compressor body 1. The first transmission shaft 41 is rotatably mounted on the H-shaped fixing plate 46, the first transmission gear 42 is fixedly mounted on the first transmission shaft 41, the second transmission shaft 45 is rotatably mounted on the H-shaped fixing plate 46, and the second transmission gear 43 is fixedly mounted on the output shaft 6. The transmission belt 44 is sleeved on the first transmission shaft 41 and the second transmission shaft 45. The rotation of the output shaft 6 drives the second transmission gear 43 to rotate, the second transmission gear 43 drives the first transmission gear 42 to rotate, the first transmission gear 42 drives the first transmission shaft 41 to rotate, and the first transmission shaft 41 drives the transmission belt 44 to drive the second transmission shaft 45 to rotate.

[0024] Specifically, the piston mechanism 2 includes a piston cylinder 21, a reciprocating screw 22, a piston plate 23, a telescopic rod 24, and two limiting rods 25. The piston cylinder 21 is fixedly mounted on the magnetic levitation air compressor body 1. The two limiting rods 25 are fixedly mounted on the inner wall of the piston cylinder 21. The reciprocating screw 22 is fixedly mounted at the end of the second transmission shaft 45. The piston plate 23 is slidably mounted inside the piston cylinder 21. The two ends of the telescopic rod 24 are fixedly mounted between the piston cylinder 21 and the piston plate 23. The second transmission shaft 45 drives the reciprocating screw 22 to rotate, which in turn drives the piston plate 23 to move back and forth. The reciprocating movement of the piston plate 23 continuously draws in cooling gas into the piston cylinder 21 and discharges it. This simulates a breathing-like cooling method, allowing the gas to circulate and further increasing the cooling effect.

[0025] Specifically, the piston plate 23 meshes with the reciprocating lead screw 22, and the piston plate 23 is provided with a limiting groove for the limiting rod 25 to pass through.

[0026] Specifically, four first check valves 26 are connected and disposed on the piston plate 23.

[0027] Specifically, the cooling mechanism 3 includes a hollow ring 31, two connecting pipes 32, a coolant ring 33, a liquid filling pipe 34, and a second one-way valve 35. The hollow ring 31 is fixedly installed on the top of the magnetic levitation air compressor body 1, the coolant ring 33 is fixedly installed inside the hollow ring 31, the liquid filling pipe 34 is connected to the top of the coolant ring 33, the two connecting pipes 32 are respectively connected to the hollow ring 31 and the piston cylinder 21, and the second one-way valve 35 is installed on the hollow ring 31. The piston plate 23 moves away from the hollow ring 31, reducing the air pressure inside the piston cylinder 21 and drawing the cooling gas inside the hollow ring 31 into the piston cylinder 21. Simultaneously, external air is drawn into the hollow ring 31 through the second one-way valve 35. The air in the hollow ring 31 is stored as cold air due to the heat conduction effect of the cooling ring. This allows the reciprocating speed of the piston plate 23 to be adjusted according to the rotational speed of the output shaft 6, thus enabling adaptive adjustment of the frequency of air-to-cold air exchange. This ensures that the temperature of the magnetic levitation air compressor body 1 remains at a suitable operating temperature regardless of its power output, thus guaranteeing the service life of the magnetic levitation air compressor body 1, reducing rotor bearing friction, eliminating the need for manual monitoring and adjustment, and achieving a high degree of automation.

[0028] Working principle: The magnetic levitation air compressor body 1 drives the output shaft 6 to rotate, which in turn drives the second transmission gear 43 to rotate. The second transmission gear 43 drives the first transmission gear 42 to rotate, which in turn drives the first transmission shaft 41 to rotate. The first transmission shaft 41 drives the transmission belt 44 to drive the second transmission shaft 45 to rotate, which in turn drives the reciprocating screw 22 to rotate. The reciprocating screw 22 drives the piston plate 23 to move back and forth. As the piston plate 23 moves away from the hollow ring 31, the air pressure inside the piston cylinder 21 decreases, thereby drawing the cooling gas inside the hollow ring 31 into the piston cylinder 21. Simultaneously, external air is drawn into the hollow ring 31 through the second one-way valve 35. The air in the hollow ring 31 is then cooled and stored as cold air due to the heat conduction effect of the cooling ring.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
