[0025] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-surge device for a centrifugal compressor, including a base 1, an anti-surge body 2 fixedly connected to the upper surface of the base 1, a top cover 3 fixedly connected to the top of the anti-surge body 2, an air pipe 4 fixedly connected to the outer surface of the anti-surge body 2, and an installation mechanism 5 fixedly connected to the outer surface of the air pipe 4.

[0026] In this embodiment, the anti-surge body 2 is fixed by the base 1, the top cover 3 is fixed by the anti-surge body 2, the air pipe 4 is fixed by the anti-surge body 2, and the installation mechanism 5 is fixed by the air pipe 4. When the pump inside the compressor is not pumping enough air, the anti-surge body 2 will open the internal valve to allow gas to enter the compressor and supplement the air, thereby preventing surge.

[0027] Example 2

[0028] like Figures 1-4As shown, an installation ring 6 is fixedly connected to the outer surface of the installation mechanism 5. Multiple telescopic rods 7 are fixedly connected to the outer surface of the installation ring 6. A sliding ring 8 is fixedly connected to the output end of each telescopic rod 7. Multiple rotating blocks 9 are rotatably connected inside the sliding ring 8. A rubber pad 10 is fixedly connected to the outer surface of each rotating block 9. Fastening mechanisms 11 are rotatably connected to both sides of the installation ring 6. A connecting ring 12 is provided on the outer surface of the fastening mechanism 11. A fastening rope 13 is provided on the outer surface of the connecting ring 12. Connecting rods 14 are fixedly connected to both sides of the sliding ring 8. The outer surface of the connecting rod 14 is movably connected to the other end of the fastening rope 13, and the other end of the connecting rod 14 is fixedly connected to a... The positioning ring 15 and the limiting ring 15 are used to prevent the fastening rope 13 from falling off. The other end of the fastening mechanism 11 is fixedly connected to a handle 16. The handle 16 can drive the fastening mechanism 11 to rotate inside the mounting ring 6. A certain port of the compressor is inserted into the interior of the mounting mechanism 5. The outer surface of the mounting mechanism 5 is slidably connected to the interior of the sliding ring 8. The lower surfaces of multiple rubber pads 10 are all attached to the outer surface of the compressor port, so that it can be tightly connected to the mounting mechanism 5 to avoid air leakage. The limiting ring 15 prevents the fastening rope 13 from falling off the outer surface of the connecting rod 14. The sliding ring 8 can be fixed by the cooperation between the connecting rod 14 and the fastening rope 13.

[0029] In this embodiment, the entire device is first placed at the port of the compressor. Then, the port is inserted into the interior of the mounting mechanism 5. The telescopic rod 7 on the outer surface of the mounting ring 6 is activated. The telescopic rod 7 can move the sliding ring 8 to slide on the outer surface of the mounting mechanism 5. When the sliding ring 8 is retracted, it can drive the multiple rotating blocks 9 on the outer surface to rotate, thereby driving the multiple rubber pads 10 to connect with the port, thus tightly fitting the port with the interior of the mounting mechanism 5. This allows the anti-surge body 2 to directly send air into the interior of the compressor through the mounting mechanism 5 and the port. After installation, the handle 16 is manually turned. The handle 16 drives the fastening mechanism 11 to rotate on the outer surface of the mounting ring 6. The fastening mechanism 11 drives the connecting ring 12 to rotate. When the connecting ring 12 rotates, it will drive the fastening rope 13 on the outer surface to wind up.

[0030] The working principle of this embodiment is as follows: First, the entire device is placed at the port of the compressor. Then, the port is inserted into the interior of the mounting mechanism 5. The telescopic rod 7 on the outer surface of the mounting ring 6 is activated. The telescopic rod 7 allows the sliding ring 8 to slide on the outer surface of the mounting mechanism 5. When the sliding ring 8 retracts, it drives the multiple rotating blocks 9 on the outer surface to rotate, thereby driving the multiple rubber pads 10 to connect with the port, thus tightly fitting the port with the interior of the mounting mechanism 5. This allows the anti-surge body 2 to directly deliver air into the compressor through the mounting mechanism 5 and the port. After installation, the handle 16 is manually turned. The handle 16 drives the fastening mechanism 11 to rotate on the outer surface of the mounting ring 6, and the fastening mechanism 11 drives the connecting ring 12 to rotate. When the connecting ring 12 rotates, it will cause the fastening rope 13 on the outer surface to coil up. Coiling the fastening rope 13 into a taut state can fix the sliding ring 8, preventing shaking or movement and improving the tightness between the port and the mounting mechanism 5. The anti-surge body 2 is fixed by the base 1, the top cover 3 is fixed by the anti-surge body 2, the air pipe 4 is fixed by the anti-surge body 2, and the mounting mechanism 5 is fixed by the air pipe 4. When the pump inside the compressor is not pumping enough air, the anti-surge body 2 will open the internal valve to allow gas to enter the compressor and supplement the air, thus preventing surge. The limiting ring 15 prevents the fastening rope 13 from falling off the outer surface of the connecting rod 14. The cooperation between the connecting rod 14 and the fastening rope 13 can fix the sliding ring 8.
