Water Hammer Alleviators
Water hammer alleviators attenuate bang from reverse flow when pumping system
stops, by being placed immediately after the delivery outlet.
Water hammer alleviators arrest the flow gently preventing water hammer;
it is the increase in time for deceleration that counts.
Water hammer alleviators suppress the surges from centrifugal fast motor spin-up. when a loop back to source, with metered restriction was not provided.
Water hammer alleviators also used for volume compensation with temperature
change, by functioning as an accumulator.
Water hammer alleviators for attenuating surges in pipes with surging liquids,
are needed to suppress a shock.
Water hammer alleviators for smoothing the shock when a pump starts;
these shock alleviators are installed down stream of discharge check valve.
Water hammer alleviators dampen the system overpressure from a fast start-up;
required when there is no flow back bypass to suction.
Water hammer alleviators stop the shock from quick valve closure and isloator
slam; and work best, when mounted as close to the isolating valve as possible.
Water Hammer Alleviator
Water hammer alleviators attenuates hammer from reverse flow when stopping
pumps; catching the weight of the returning fluid, with progressive
resistance.
Water hammer alleviators arresting the flow gradually, so preventing water
hammer, by prolonging the period of slow down.
Water hammer alleviators suppresses the shock on fast motor spin-up of
centrifugals, when a metered resistance, looping back to inlet, has not been provided.
Water hammer alleviators are used for compensating volume on temperature
variations, giving excess volume somewhere to go without a large pressure increase.
Water hammer alleviators attenuates a shock in a pipe having liquids that are
surging, by stabilizing the mass oscillation with their cushioning.
Water hammer alleviators for leveling the shock when pumps are started;
this shock alleviator is piped in, just after of the discharge check valve.
Water hammer alleviators dampening system overpressure with instant start-up,
is by substituting for a flow back bypass going to source of supply.
Water hammer alleviators stopping shocks from quick valve closure, isloator
slam,
is most efficient, when positioned adjacent the isolation valve.
