Pressure dampers are used to dampen pulsation. Pulsation is measured and seen as a repeated change in pressure. Pressure dampers address pressure amplitude at frequency. The characteristics of a pressure damper have to be designed to respond to the height and fall of pressure at the frequency of the change. A flow through, in and out, pressure damper intercepts the pressure transients so it can respond to its dampening with maximum efficiency and minimum cost.
Flow fluctuation suppression devices for “pulsing systems” may be called reactive or non-reactive / passive in pressure response. Intrinsically when a proportion of head change due to mass acceleration is prevented from occurring by the application of the softness, or cushion, of a liquid accumulator there is still a residual fluctuation. The head change or pressure change that is still residual travels at 1400 meters per second away from the pump, until it meets a point of reflection. Where the distance to the reflection point is say 700 meters, the wave will return in 1 second. This pressure spike (liquid force) will impose a system response frequency of one hertz on the piping.
