"What can we do for you?"

Hydraulic / Hydropneumatic Accumulators and the like are extensively use in the Exploration and production Oil Industry, please see hydrotrole.co.uk. 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."Hydro-Pneumatic-Technologies"

Pulse Damping with Dampeners for Pressure Pulsation and Flow Smoothing and stabilization, aka de-surging. 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.1.

Pipe line Shock, pump Surge, acoustic Silencing, Water Hammer prevention, with descriptions like Arrestors, Alleviators, and Attenuators. Directory.Water-Hammer.com: 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 compression of a nitrogen or air. 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 one of these arrestor, desurger, hammer absorbers, 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.2.

Modeling of Pulsation in combination with symptoms ex Vibration, its Analysis from data capture is a Liquid Dynamics Technical Service. LiquidDynamicsInternational.net: Technical services offered enable the prediction of piping problems before the expenditure on piping and 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 recommend dimension and component changes that will reduce or even remove pulsations, shocks, hammers, and the vibration they can induce.4.

Pulse-Acc.com Contact InfoTech@Pulse-Acc.com Communications and navigation center for:- Hydro-Pneumatic-Technologies aka hydraulic and pneumatic technology, meaning the interplay or incompressible liquids with the elasticity of compressible gas, often the gas is Nitrogen, and the liquid is a chemical process or hydrocarbon fluid. This is the science behind Liquid Dynamics International Inc that does computer modeling in this area. Pulsation Damper Safety Login Page The science behind the PulseGuard inc activity is more specifically related to the response charactereistics of pressure and flow in pipelines that are excited by a forcing action from a pump. The techniques deployed by SHOCKGUARD are for preventing pipe line shock and water hammer, whereas the PULSE-ACC program is devoted to low cost low pressure readily availability of equipment in large quantity for flow velocity stabilization with de-surgers.
