How did the pneumatic symbol of stainless steel pneumatic butterfly valve come from? When the excitation frequency is lower than the natural frequency of the mass (equipment) ball valve system, the shock absorber does not play the role of vibration isolation; When the excitation frequency is close to the natural frequency, the vibration will be amplified; Only when the excitation frequency is greater than the square root of the natural frequency, can the shock absorber have the effect of reducing vibration
Generally, the excitation frequency is required to be 2~3 times greater than the natural frequency to obtain good vibration isolation effect
