FM-201 | Pipe Surge and Water Hammer Apparatus

In structures such as hydroelectric power plants, or in systems for supplying water, changes in flow rate result in pressure fluctuations. For example, during startup and shutdown of hydraulic machines or by opening and closing shut-off elements. There is a distinction to be made between rapid pressure changes that propagate with high velocity (water hammer) and slow pressure changes caused by mass oscillations. Pipeline systems use air vessels or surge chambers to dampen water hammer and mass oscillations. This unit is used to generate and visualise water hammer in pipes and to demonstrate how a surge chamber works. The trainer contains a pipe section with a ball valve and a surge chamber and a second pipe section with a solenoid valve. The experimental unit is connected to the FM-430 Hydraulic Bench. The water is supplied and the flow rate measured by FM-430 Hydraulic Bench. Alternatively, the experimental unit can be operated by the laboratory supply.
