Simulation - pipeline 1 - pressure profile without any protections

Example of a transient event generated by a pump trip, at first we notice a drop in pressure followed by a surge as the water column moves back towards the check valves of the pumping station.

 

Simulation - pipeline 1 - pressure profile with CSA anti-water hammer devices

Example of a transient event generated by a pump trip in presence of CSA surge anticipating valve XLC 321/421 and anti hammer air valves FOX 3F AS range. The effect of the valve with anticipated opening is evident in preventing unwanted increase in pressure with possible damages to the system.

 

Simulation - pipeline 2 - pressure profile without any protections

Example of a transient event, generated by a pump trip, leading to column separation with vapor pockets formation and collapse. This phenomenon is associated to severe and sudden high frequency changes in pressure.

 

Simulation - pipeline 2 - pressure profile with CSA anti-water hammer devices

Example of a transient event generated by a pump trip in presence of CSA surge vessel AVAST (patent pending) and anti hammer air valves FOX 3F AS range. The effect of the AVAST pushing water back into the system, following a pump trip, is evident to contain the drop of the hydraulic grade line and prevent negative pressure conditions.
