The water hammer

Experience shows that any rapid change in flow velocity

Sudden pressure fluctuations can occur in the water in a pipeline.

• These disturbances, i.e., the rapid alternation of overpressure and underpressure,

They reach their maximum extent when the water flow is increased by rapid

The process is interrupted abruptly due to the closing of a device (valve or tap) or due to accidental circumstances, such as a pump stopping.

The resulting overpressures spread at high speed through the flow medium and trigger a series of enormous impacts both

on the device that interrupted the water flow, as well as on the pipeline in which this device is installed.

The phenomenon described above is called water hammer.

and is often accompanied by vibrations and loud noises.

The extent of the resulting overpressure depends on the closing time.

the devices that determine the change in flow rate,

and also influenced by other factors.

In modern sanitary installations, the phenomenon of water hammer occurs due to the increasing use of quick-closing fittings,

such as single-lever mixers, solenoid valves, ball valves, etc., are becoming increasingly common. In fact, these devices cause

The extremely short closing times result in an immediate interruption of the water flow and thus the occurrence of water hammer.

Water hammer pressures very often reach high values ​​and cause the following problems:

• Breakage of pipes, circulation pumps, domestic hot water storage tanks, combination storage tanks, fresh water stations, containers and hoses;
• Wear and tear of fittings and welds;
• Damage to shut-off devices, backflow preventers and control devices;
• loud noises and vibrations in pipelines and surrounding structures;
• Premature wear and tear of the sanitary fittings.
