Table 1 Characteristics of various pressure pulsation attenuators
Type | Working frequency | Attenuation mechanism | Advantages | Disadvantages |
|---|---|---|---|---|
Resistive | Unlimited | Damping and friction | Obvious attenuation effect | Serious fever and large energy loss |
Reactive | Narrow | Resonance and interference of pressure pulsation wave | Stable work | Larger volume |
Composite | Wide | Friction and resonance | Wide working frequency band, good effect | Large volume and difficult design |
