Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a vibration reduction device for compressors. Background Art

[0002] Existing compressors use rubber compressor pads to reduce vibration. The compressor pads are important components used to connect the compressor and the base plate. Their vibration reduction effect directly affects the vibration and noise level of the entire compressor system. When the natural frequency of the compressor pad is close to the operating frequency of the compressor, most of the vibration excitation of the compressor will be transmitted to the base plate through the compressor pad, which will then cause the base plate to resonate and generate fundamental frequency resonance noise, affecting the user experience. Existing compressor pads have a single structure and can only maintain stability in a single direction, either vertically or horizontally.

[0003] For example, Chinese patent publication number CN108981021A, published on December 11, 2018, is titled "Shock-absorbing components, compressors and air conditioners", and includes a shock-absorbing pad; a support member, the shock-absorbing pad is arranged on the support member, and the support member is used to reduce the deformation of the shock-absorbing pad. The present invention reduces the deformation of the shock-absorbing pad by arranging a support member inside the shock-absorbing pad, which is equivalent to hardening the inside of the shock-absorbing pad, which can limit the vibration of the compressor, thereby effectively reducing the impact of the compressor vibration on the pipeline components, thereby achieving the effect of reducing the pipeline strain value.

[0004] The disadvantages of the existing patents are that the existing compressor foot pads have a single structure and can only maintain stability in a single direction, either vertically or horizontally, and have a general vibration reduction effect. Utility Model Content
