Hydraulic / Hydropneumatic Accumulators, Exploration, Oil Industry
Hydropneumatic-Accumulators.com
Hydropneumatic / hydraulic accumulators store fluid power to operate valve actuators for emergency shutdown and shut-in of systems. Hydraulic power is also stored for the operation of blow out prevention systems. Hydraulic / hydro pneumatic accumulators provide counter balance force and connected to hydraulic cylinders are heave motion compensators.
Pulse Damping, Dampeners, Pressure Pulsation, Flow Smoothing
The-Pulsation-Dampener-Directory.com
A pulsation damper enables instantaneous variations in flow from a pump without instant increase and decrease in pressure. The apparent "dampening" is from the accumulator effect of the "dampener" storing sudden increases of flow and then delivery of the stored flow into the system when flow rate decreases. Dampners provide a cushion that prevents unnecessary acceleration head change. Effectively pulsation pressure changes are prevented from occurring - pressure pulsation is prevented from occurring, not allowed to happen, and then "dampened".
Pipe Shock, Surge, Silencing, Water Hammer, Arrestors, Alleviators, Attenuators

Water hammer is the audible result of sudden pressure change. The most common cause of water hammer is the shock wave from quick closing of a valve. The instant deceleration of mass flows that results in the "bang" is removed by creating time over which the deceleration takes place. The increase in time for deceleration is achieved by providing a volume into which to mass may continue to flow, against increasing resistance, caused by the comparison of a gas. These devices may be known as shock absorbers. However they do not absorb, attenuate, or alleviate a shock that has been created - all these alleviators and alternatives actually stop a shock from occurring. When an arrestor, desurger, hammer absorber is placed after a pump that may be started suddenly, these devices prevent start-up surge. These products are also applied as volume compensators for liquid expansion and contraction due to liquid temperature change, they have similar names.
Pulsation / Vibration Analysis, Liquid Dynamics Technical Services
LiquidDynamicsInternational.net
Technical services offered enable the prediction of piping problems before the expenditure on piping ans associated equipment. This pre-emptive approach may provide large savings. Where an installation has gone ahead without first making a piping model, we create the system model to enable diagnosis of the problem and reccomend dimension and component changes that will reduce or even remove pulsations, shocks, hammers, and the vibration they can induce.
