Pipe Surge & Water Hammer Apparatus
The apparatus is designed to generate and visualise water hammers in pipes and to demonstrate how a surge chamber works. The trainer contains a pipe section with a surge pipe, solenoid valve & ball valve.In the first experiment a pipe surge is produced by rapidly closing the solenoid valve. The sudden deceleration of the water mass releases kinetic energy, which is converted into potential energy in the surge pipe.
The resulting pressure oscillations are measured by a pressure sensor in the pipe.The oscillations are plotted on a strip chart recorder. The oscillation can also be seen as pendulum movement of the water level in the surge chamber.In the second experiment the valve at base of surge pipe is closed so that the rapid closing of the solenoid valve in the pipe section produces a strong water hammer.
