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