Description

Technical Field

[0001] This utility model relates to the field of centrifugal compressor technology, and in particular to the compressor head of a two-stage magnetic levitation high-speed centrifugal compressor. Background Technology

[0002] The two-stage magnetic levitation high-speed centrifugal compressor is a highly efficient and energy-saving device that uses magnetic bearings to support the rotor and compresses gas stage by stage through two centrifugal impellers. Its rotor operates without contact under magnetic levitation, avoiding mechanical friction and offering advantages such as high speed, low noise, low vibration, and no lubrication required, while also reducing energy loss and maintenance costs. Due to its two-stage compression method, it can achieve higher compression ratios and efficiencies within a smaller volume, making it suitable for supplying clean compressed air and gases in the electronics, chemical, and energy industries.

[0003] In existing technologies, it is inconvenient to move the compressor head, making it difficult to adjust its position in a timely manner during installation or maintenance. This often requires repeated manual handling or the use of additional tools, which not only increases the difficulty and labor intensity of operation, but also makes it easy for the compressor head and the compressor connection to be difficult to align precisely, thus affecting assembly efficiency and operational stability.

[0026] 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.

[0027] Example 1: Refer to Figure 1 and Figure 2 The present invention provides an embodiment of a two-stage magnetic levitation high-speed centrifugal compressor head, including a positioning plate 1, a moving component 2 on the outer side of the positioning plate 1, support rods 3 at the four corners of the upper surface of the positioning plate 1, and adjusting rods 4 inserted at the upper ends of the four sets of support rods 3, mounting plates 5 installed at the upper ends of the four sets of adjusting rods 4, and a head body 6 on the front side of the mounting plate 5.

[0028] Specifically, by setting the positioning plate 1 in a suitable position and then adjusting the height of the adjusting rod 4 at the upper end of the support rod 3, the height of the mounting plate 5 can be adjusted by moving the adjusting rod 4. This allows the mounting plate 5 to drive the machine head body 6 to align with the compressor, thus facilitating the connection between the machine head body 6 and the compressor.

[0029] Reference Figure 3 The moving component 2 includes four sets of moving wheels 201. The four sets of moving wheels 201 are installed at the four corners of the lower surface of the positioning plate 1. Positioning plates 202 are provided on both the front and rear sides of the positioning plate 1. Positioning rods 203 are inserted into the middle of the two sets of positioning plates 202 through a threaded structure. Positioning blocks 204 are installed at the lower end of the positioning rods 203. A throttle 205 is installed at the upper end of the positioning rods 203.

[0030] Specifically, the positioning plate 1 can be easily moved by the movable wheel 201. After being moved to the appropriate position, the positioning rod 203 moves in the middle of the positioning piece 202 by rotating the handle 205, thereby driving the positioning block 204 to contact the ground and fix the position of the positioning plate 1.

[0031] Reference Figure 5 A heat-conducting plate 7 is fixedly installed on the rear side of the machine head body 6, and three sets of heat pipes 8 are inserted in the middle of the heat-conducting plate 7. Multiple sets of fins 9 are sleeved on the rear end of the three sets of heat pipes 8, and two sets of cooling fans 10 are installed on the upper surface of the multiple sets of fins 9.

[0032] Specifically, the heat-conducting plate 7 can conduct the heat generated during the operation of the machine head body 6 into the heat pipe 8, and then the multiple sets of fins 9 fitted at the rear end of the heat pipe 8 significantly increase the heat dissipation area and accelerate the exchange speed of air and heat. The two sets of cooling fans 10 installed on the upper surface of the multiple sets of fins 9 can quickly dissipate the heat inside the fins 9.

[0033] Reference Figure 6 Four sets of adjusting rods 4 are respectively movably inserted into the upper end of four sets of support rods 3, and fixed bolts are provided on the outer side of each of the four sets of support rods 3. The lower ends of the four sets of adjusting rods 4 are connected by four sets of connecting rods 11, and two sets of matching sliding grooves are opened on the side of each of the four sets of support rods 3 that are close to each other.

[0034] Specifically, the height of the upper end of the adjusting rod 4 can be adjusted at the upper end of the four sets of support rods 3. Through the cooperation of the four sets of connecting rods 11 and the sliding groove, the height of the four sets of adjusting rods 4 can be moved synchronously. Then, the height of the adjusting rod 4 can be fixed by the fixing bolt.

[0035] Reference Figure 6 The upper end of the four sets of support rods 3 is provided with an I-shaped mounting bracket 12, and the front and rear sides of the mounting bracket 12 are movably inserted with limiting rods 13, and the lower end of the two sets of limiting rods 13 is installed with mounting strips 14. The middle position of the lower surface of the mounting strip 14 is provided with a drive motor 15, and the upper end of the drive motor 15 is connected with a path rod 16. The path rod 16 is inserted into the middle position of the mounting bracket 12 through a threaded structure, and the upper end of the path rod 16 is rotatably installed on the lower surface of the mounting plate 5.

[0036] Specifically, by turning on the drive motor 15, the path rod 16 is driven to rotate in the middle position of the mounting bracket 12 and on the lower surface of the mounting plate 5. Then, the path rod 16 is moved in the middle position of the mounting bracket 12 through the threaded structure. The position of the mounting strip 14 is restricted by the set limit rod 13 to prevent the mounting strip 14 from rotating, thereby adjusting the position of the path rod 16, and then driving the mounting plate 5 to move through the path rod 16.

[0037] Example 2: Refer to Figure 4 The moving component 2 includes four sets of moving wheels 201. The four sets of moving wheels 201 are installed at the four corners of the lower surface of the positioning plate 1. Each set of moving wheels 201 has a fixing rod 206 on its front side, and each set of fixing rods 206 has a positioning seat 207 sleeved on its lower end through a threaded structure.

[0038] Specifically, the movable wheel 201 is moved to a suitable position, and then the position of the positioning seat 207 at the lower end of the fixed rod 206 is rotated so that the positioning seat 207 moves through the threaded structure and contacts the ground, thereby fixing the position of the positioning plate 1.

[0039] Working principle: The positioning plate 1 can be easily moved to a suitable position by the moving component 2. Then, the drive motor 15 is turned on, and the mounting plate 5 is moved on the upper side of the mounting frame 12 by the cooperation of the path rod 16 and the limit rod 13. Then, the four sets of adjusting rods 4 are moved synchronously on the support rod 3 by the connecting rod 11, so as to facilitate the alignment of the machine head body 6 with the compressor and the connection between the compressor and the machine head body 6. When the machine head body 6 is working, the heat generated by the machine head body 6 can be discharged to the heat pipe 8 by the heat conduction plate 7. Then, the heat is transferred to the space between multiple sets of fins 9 by the heat pipe 8, and then the heat is dissipated by the cooling fan 10.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
