Technical Field

[0001] This utility model relates to the field of compressor parts technology, specifically to a centrifugal compressor housing. Background Technology

[0002] Centrifugal compressors, also known as "vortex compressors," are a type of compressor. Their structure and operating principle are similar to centrifugal blowers, but they are always multi-stage, enabling them to achieve higher gas pressures, larger throughput, and higher efficiency. Centrifugal compressors typically have an external casing to protect the internal components.

[0003] Existing compressor housings and covers are often connected and fixed with multiple bolts, making disassembly cumbersome. Furthermore, with prolonged use, the bolts may corrode, making separation of the housing and cover difficult when internal components need maintenance. Therefore, we propose a new centrifugal compressor housing design. Utility Model Content

The limiting block is slidably connected in the guide groove. A connecting rod is provided on the outer wall of the limiting block. The other end of the connecting rod extends through to the outside of the fixed seat. A limiting hole is provided on the outer wall of the connecting seat. The limiting hole corresponds to the limiting block in position and size.

[0008] Preferably, a pull ring is rotatably connected to one end of the connecting rod that extends to the outside of the fixed base, and a rubber sleeve is nested on the pull ring.

[0009] Preferably, a spring is nested on the connecting rod, and the spring is pressed between the outer wall of the limiting block and the inner wall of the guide groove.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a centrifugal compressor housing.

[0025] The utility model provides Figure 1-4 The centrifugal compressor housing shown includes a housing 1 and a cover 2. The housing 1 is provided with multiple limiting mechanisms 3. The inner wall of the housing 1 is provided with an installation groove 4. The outer wall of the cover 2 is provided with a connecting seat 14. The cover 2 is connected to the housing 1 through the connecting seat 14. The limiting mechanism 3 includes a fixed seat 6 and a limiting block 8. The fixed seat 6 is disposed on the outer wall of the housing 1. The fixed seat 6 is provided with a guide groove 7. The guide groove 7 is interconnected with the installation groove 4. The limiting block 8 is slidably connected in the guide groove 7. The outer wall of the limiting block 8 is provided with a connecting rod 9. The other end of the connecting rod 9 extends to the outside of the fixed seat 6. The outer wall of the connecting seat 14 is provided with a limiting hole 15. The position and size of the limiting hole 15 correspond to those of the limiting block 8.

[0026] The present invention relates to a centrifugal compressor housing, wherein a pull ring 10 is rotatably connected to one end of the connecting rod 9 that extends through to the outside of the fixed base 6, and a rubber sleeve is nested on the pull ring 10, which can easily drive the connecting rod 9 and the limiting block 8 to move, thereby improving the ease of operation.

[0027] The centrifugal compressor housing of this utility model has a spring 11 nested on the connecting rod 9. The spring 11 is pressed between the outer wall of the limiting block 8 and the inner wall of the guide groove 7. Through the elastic force of the spring 11, a certain pushing force can always be applied to the limiting block 8, so that it can always maintain a snap-fit ​​state with the limiting hole 15, avoiding separation between the two and affecting the connection stability.

[0028] This utility model discloses a centrifugal compressor housing. A fixing plate 12 is provided on the outer wall of the fixing base 6. An arc-shaped groove is provided on the fixing plate 12. A stop bar 13 is provided on the outer wall of the pull ring 10. The size of the stop bar 13 matches the arc-shaped groove. When the operator removes the housing cover 2, after the limiting block 8 is separated from the limiting hole 15, the stop bar 13 is inserted into the arc-shaped groove to limit the position of the limiting block 8. This makes it easy for the operator to remove the housing cover 2, and no multiple people are required. One person can operate it.

[0029] The present invention relates to a centrifugal compressor housing, wherein a limiting groove 5 is provided on the inner wall of the mounting groove 4, and a guide block is provided on the outer wall of the connecting seat 14. The connecting seat 14 is fitted and connected to the limiting groove 5 through the guide block, which can provide a guiding function for the housing cover 2 when it is installed, so as to avoid the need to rotate the housing cover 2 back and forth to adjust the position of the limiting hole 15 after the connecting seat 14 is inserted into the mounting groove 4.

[0030] The centrifugal compressor housing of this utility model has inclined surfaces on both the limiting block 8 and the connecting seat 14. The corresponding surfaces of the two inclined surfaces are consistent, which makes it convenient to directly insert the connecting seat 14 into the mounting groove 4.

[0031] The centrifugal compressor housing of this utility model has a rectangular guide groove 7 and a corresponding limit block 8, which can prevent the limit block 8 from rotating arbitrarily during use and affecting the performance.

[0032] In use, when installing the cover 2, first align the guide strip on the connecting seat 14 with the limiting groove 5, then insert the connecting seat 14 into the mounting groove 4. After the connecting seat 14 is inserted into the mounting groove 4, it will first contact the limiting block 8. Since both have inclined surfaces, and the corresponding surfaces of the inclined surfaces are aligned, the limiting block 8 can be directly pushed into the guide groove 7. After the connecting seat 14 is fully inserted, the limiting hole 15 will move to the position of the limiting block 8. At this point, the limiting block 8 loses external pushing force and will enter the limiting hole 15 under the elastic action of the spring 11, thereby limiting the cover 2. The cover 2 is now installed. When disassembling the cover 2, simply pull the pull ring 10 in sequence to separate the limiting block 8 from the limiting hole 15. Then rotate the pull ring 10 to make the stop bar 13 lock in the arc groove. After all the limiting blocks 8 are separated from the limiting hole 15, the cover 2 loses its limiting effect and can then be removed.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
