Water hammer, a hydraulic shock wave caused by the sudden interruption or change in flow of water within a piping system, can pose serious risks to fire pump systems if not properly addressed. Potential consequences of water hammer include damage to pipes, fittings, valves, and other system components, as well as increased stress on the fire pump and associated equipment. To mitigate water hammer, various measures can be implemented, including the installation of surge suppressors, air chambers, or hydraulic accumulators to absorb excess pressure fluctuations and dissipate energy. Additionally, proper design of the piping layout, valve configurations, and system operating procedures can help minimize the occurrence of water hammer and ensure the safe and reliable operation of the fire pump system.
