Description



The equipment is free-standing and comprises two stainless steel test pipes connected to a constant head tank with the necessary connections to an F1-10 Hydraulics Bench.

Pipe surge demonstrations are conducted using the first test pipe, which incorporates a transparent surge shaft with scale and a lever operated valve at the discharge end. An additional valve downstream enables the flow through the test pipe to be varied before closing the lever operated valve. An electronic pressure sensor located at the base of the surge shaft enables the low-speed transients in water level to be measured.

Water hammer demonstrations are conducted using the second test pipe, which incorporates a fast-acting valve at the discharge end. An additional valve downstream enables the flow through the test pipe to be varied before closing the fast-acting valve.

The unique fast-acting valve, specifically designed by Armfield, enables water hammer to be generated in a relatively short length of straight

pipe because of the extremely short closure time achieved using a trigger actuator.

Tappings incorporating electronic pressure sensors are located in the test pipe adjacent to the fast-acting valve and halfway along the test pipe.

These sensors measure the high-speed pressure transients inside the pipe as the water hammer travels backward and forward along the test pipe. The time delay between the sensors can be used to determine the speed of sound through the water that is attenuated by the elasticity of the metal pipe wall.

All three pressure sensors are connected to a conditioning unit with USB connection for direct connection to a PC (not supplied by Armfield).

The transient pressure waves can be analysed on the PC (not supplied) using the software supplied. The pressure sensors are powered from the USB port on the PC so no additional power supply is necessary.
