Hammer Eliminators from ShockGuard
Hammer eliminators eliminate hammering in circuits so that they do not
excite the tube runs and fracture the joints.
Hammer eliminators are absolutely required when pump spin-up is without VSG ramp
up, and so the attempted mass acceleration makes a pressure transient that
reverberates acoustically at be the same mechanical frequency as the natural
response of any part of the design.
Hammer eliminators are inserted adjacent the hammering instigator, safety
shut down method or block, as is practicable.
A hammer eliminator is connected, to maximize the weight of liquid that may
be cushioned by the compressibility of the pre-fill nitrogen within the
hammer eliminator. This means that it has to go before a column of liquid that
must be accelerated, or at the end of a line that is to be periodically
decelerated.
