LDi - Water Hammer and Shock Analysis, Diagnostics, and Prediction by Software.

Shock Prevention Hardware

Schematic of a water-hammer susceptible system

This system could have had a water hammer problem if the valve was closed to quickly or the pump was started up too quickly. The LDi LiquiCrat (provided it has been correctly sized and installed) will prevent any water-hammer occurring. When the valve is closed too quickly, normally all the liquid would have to suddenly stop. The LiquiCrat provides a space into wich the liquid can flow. As it flows into the space, it compresses a gas-filled bladder, so as the space fills, the bladder provides an increasing resistance. In this way, the liquid can be decelerated more slowly, preventing the formation of a shock wave. The same process happens when the pump is started up too quickly.

LDi manufacture a wide range of shock preventors to suit all systems. Find out which suits your particular system. Alternatively, LDi's ShockView software can provide an analysis of the system to determine how slowly the valve should be closed or the pump started up to prevent the shock wave forming.

If you have a pipeline or pump user problem which requires pulsation analysis, diagnostics, or prediction by software:
The definitions of many problems can be found at Liquid-Dynamics.com. Or send your problem to LiquidDynamics.net.

Liquid Dynamics provides pipeline and pump user problem analysis, diagnostics, and prediction by software. For water hammer and shock solutions pulsation dampening and shock alleviating devices can be obtained from our associate websites PulseGuard and ShockGuard.
