Rubber shock absorber for the foundation of machinery vibration damping noise

Rubber shock absorber is suitable for the foundation vibration damping noise of power machinery such as pumps, compressors, blowers, freezers, compressors, etc. It is especially suitable for the foundation vibration damping of vertical pumps, made of metal and rubber compound with good iso-frequency load range of 30kg-1250kg, resistant to oil, seawater and salt. Large internal friction, good damping effect, conducive to high-frequency vibration and noise attenuation. The modulus of elasticity is much smaller than that of metal, which can produce large elastic deformation, no sliding part, easy maintenance and low quality. It can be adjusted by formula design. With large elastic deformation and small elastic modulus, rubber impact stiffness is greater than dynamic stiffness and dynamic stiffness is greater than static stiffness, which is conducive to reducing impact deformation and dynamic deformation.
Rubber shock absorber is highly elastic and viscoelastic. As an important vibration damping element, compared with steel, its area is equal to each vibration cycle into thermal vibration. The impact stiffness is higher than the static stiffness and dynamic stiffness, the internal friction is large, and the damping effect is good, which is conducive to crossing the resonance zone and attenuating high-frequency vibration and noise. Modulus of elasticity is much smaller than metal, can produce larger elastic deformation, no sliding part, easy maintenance, low mass, easy installation and disassembly, impact stiffness is higher than static stiffness and dynamic stiffness.
