The impact during the startup of the compressor and the vibration during operation will be transmitted to various parts of the unit refrigeration system through the suction and exhaust pipes, and the air pipe may burst due to vibration fatigue, affecting the normal operation of the entire unit equipment. Summary of the Utility Model
[0003] The present application aims at the above-mentioned disadvantages in the existing production technology, and provides a compressor air pipe vibration damping seat, which can absorb the vibration of the compressor, reduce the occurrence of the rupture of the refrigeration pipeline due to vibration fatigue, and avoid the damage of the compressor pipeline due to impact and large-amplitude vibration.
[0004] The technical solution adopted by the utility model is as follows:

An air pipe is arranged in the air pipe installation cavity, and a gap is left between the air pipe and the side wall of the air pipe installation cavity; a plurality of vibration damping component installation cavities are arranged in the air pipe clamp seat, and a telescopic vibration damping component is arranged in each vibration damping component installation cavity. One end of the vibration damping component extends into the air pipe installation cavity and presses against the outer surface of the air pipe.
[0006] Further, the plurality of vibration damping component installation cavities are uniformly distributed along the circumferential direction of the air pipe installation cavity.
[0007] Further, the air pipe clamp seat includes an upper clamp seat and a lower clamp seat which are arranged corresponding to each other up and down. The upper clamp seat and the lower clamp seat are connected into a whole by a plurality of screws.

[0017] The following combines the drawings to illustrate the detailed embodiment of the present utility model.
[0018] Such as Figure 1As shown in the figure, a vibration damping seat for a compressor air pipe includes an air pipe clamp seat. A circular air pipe installation cavity for passing through the intake and exhaust pipes of the compressor is provided at the center of the air pipe clamp seat. An air pipe 10 is arranged in the air pipe installation cavity, and a gap is left between the air pipe 10 and the side wall of the air pipe installation cavity. Three vibration damping component installation cavities are arranged in the air pipe clamp seat, and the three vibration damping component installation cavities are evenly distributed along the circumferential direction of the air pipe installation cavity. A telescopic vibration damping component is arranged in each vibration damping component installation cavity. One end of the vibration damping component extends into the air pipe installation cavity and presses against the outer surface of the air pipe 10. When the compressor operates and generates vibration, the three vibration damping components absorb and release vibration energy through deformation to weaken the vibration, reduce the resonance amplitude of the pipeline system, and thus avoid structural damage to the refrigeration system pipeline due to the dynamic stress reaching the limit. At the same time, the three vibration damping components can weaken the vibration of the air pipe 10 in all directions.
[0019] As Figure 1 and Figure 2 shown in the figure, the air pipe clamp seat includes an upper clamp seat 1 and a lower clamp seat 3 arranged corresponding to each other up and down. The upper clamp seat 1 and the lower clamp seat 3 are connected into one body by a plurality of screws 2. A semi-circular upper clamping cavity is arranged on the end face of the upper clamp seat 1 facing the lower clamp seat 3, and a semi-circular lower clamping cavity is arranged on the end face of the lower clamp seat 3 facing the upper clamp seat 1. The upper clamping cavity and the lower clamping cavity are connected up and down to form a circular air pipe installation cavity.
[0020] As Figure 1 and Figure 3 shown in the figure, the vibration damping component includes a guide rod 6. The front end of the guide rod 6 extends into the air pipe installation cavity and is welded to a fixing plate 5 with a circular arc structure. A damping pad 4 with a circular arc structure is bonded to the end face of the fixing plate 5 facing the air pipe 10. The damping pad 4 with a circular arc structure can increase the force-bearing area of the air pipe 10 and further prevent the air pipe 10 from deforming under force. The rear end of the guide rod 6 is connected to a positioning nut 7 by a thread. The positioning nut 7 is used to adjust the moving amplitude of the guide rod 6. A spring 8 is sleeved on the rear end of the guide rod 6. The front end of the spring 8 contacts the rear end face of the positioning nut 7. A tightening screw 9 is arranged at the rear end of the spring 8. The tightening screw 9 is threadedly connected in the vibration damping component installation cavity, and the rear end of the spring 8 presses against and contacts the tightening screw 9. During use, by adjusting the positions of the positioning nut 7 and the tightening screw 9, the vibration damping effect of the vibration damping component is improved.
[0021] The working principle of the present utility model is as follows: When the compressor starts to operate, its vibration energy is transmitted to the vibration damping seat that fixes the suction and exhaust pipes of the compressor. At this time, the air pipe 10 contacts the damping pad 4. The damping pad 4 can reduce the ability of the pipeline system to transmit vibration, reduce the resonance amplitude of the pipeline system, thereby avoiding the structural damage caused by the dynamic stress of the refrigeration system pipeline reaching the limit. The damping pad 4 can reduce the sound radiation generated by the resonance of the refrigeration pipeline system and reduce mechanical noise. After a part of the vibration energy is weakened by the damping pad, it is transmitted to the spring 8. The spring 8 weakens the vibration by deforming to absorb and release the vibration energy, causing a small relative displacement of the air pipe 10, and reducing the damage of the vibration to the air pipe 10.
[0022] The above description is an explanation of the present utility model, not a limitation thereof. For the scope defined by the present utility model, refer to the claims. Any form of modification can be made within the protection scope of the present utility model.
