AI Technical Summary
Existing compressors are prone to generating low-frequency resonance noise during operation. Existing vibration reduction and noise reduction structures cannot flexibly adapt to vibrations of different frequencies and amplitudes, and are prone to resonance phenomena.
An auxiliary damping structure is adopted, including an inclined pulley track and auxiliary pulleys, which, together with the reset component and the main damping structure, adjust the lateral and longitudinal deflection of the compressor by the inclined setting of the pulley track and the dynamic adjustment of the reset component, thus avoiding low-frequency resonance noise.
It effectively avoids low-frequency resonance noise during compressor vibration, improves noise reduction effect, and enhances the compressor's vibration damping performance.
